"Siege" is an American comic book storyline, published by Marvel Comics from January 2010 to May 2010. It deals with the aftermath of the "Dark Reign" company-wide storyline, which led to a shift of power in the Marvel Universe toward Norman Osborn, a former supervillain who, through deception and media manipulation, has become the United States' security czar. The story also depicts the Asgardian trickster deity Loki, manipulating Osborn into leading an all-out assault to overthrow Asgard. The events in "Siege" lead to the subsequent company-wide storyline, "Heroic Age".

Publication history[link]

This section requires expansion.

Siege ran as an eponymous four-issue miniseries, with connected one-shots and associated miniseries, as well as crossovers into existing ongoing series.

Marvel announced in early 2010 that the company-wide Siege storyline will lead to a subsequent company-wide storyline, Heroic Age.^[1] This was first hinted at in-story by Athena to Amadeus Cho.^[2]

Publication aftermath[link]

The end of aftermath is described as what will be the start of a new "Heroic Age" in the Marvel Universe.^[1]

The final tie-in issues of the four Avengers titles, Mighty Avengers #36, New Avengers #64, Dark Avengers #16 and Avengers: The Initiative #35 will be the last ones of those series, along with a New Avengers: Finale one-shot, with art by Bryan Hitch.^[3]

From June there will also be a limited series called Avengers Prime: Siege Aftermath. This five part series will focus on Thor, Iron Man, and Steve Rogers and will bridge the gap between Siege and Heroic Age.

Though not badged as an aftermath series, a limited series starting in May 2010 will examine the fall of Norman Osborn and examine the effects upon his son Harry. The series is called Amazing Spider-Man Presents: American Son.^[4]

Plot[link]

Norman Osborn calls a meeting of the supervillain Cabal, consisting of Doctor Doom, the Hood, Taskmaster, and the Norse god Loki, to discuss Asgard, the home of the Norse gods, now located floating above Broxton, Oklahoma, and the last holdout in Osborn's consolidation of power. A rift develops between Doom and Osborn, creating mayhem that appears to dissolve the group. Later, under his guise of respectability, Osborn attempts in vain to secure from the President of the United States permission to invade Asgard under the claim it poses a national security threat. On Loki's advice, Osborn engineers a tragedy in which the hapless Norse god Volstagg, manipulated into battling the supervillain team the U-Foes, inadvertently causes an explosion that kills everyone in a crowded Soldier Field football stadium in Chicago, Illinois. This gives Osborn the pretext to lay siege on Asgard with military troops as well as with the Dark Avengers — his team of supervillains posing as superheroes — and with loyalists planted amid the various "50-State Initiative" teams of heroes. Osborn's aide-de-camp, Victoria Hand, growing worried over Osborn's instability, suggests unsuccessfully that Osborn seek therapy. Shortly afterward, the President realizes likewise, and orders Hand to produce Osborn.

In the meantime, in order to better control the highly powerful but psychologically fragile superhero the Sentry, who has allowed himself to be under Osborn's care, Osborn has the villainous Bullseye kill the Sentry's wife, Lindy Reynolds, and claim she committed suicide. Concurrently, Loki prepares Asgard for invasion through selective assassination and by neutralizing Heimdall, the city's guardian.

The siege begins with the Sentry attacking Asgard, followed by a massive aerial assault led by Osborn in his Iron Patriot armor. The Norse god superhero Thor is stunned and falls in battle. With the attack on Asgard instantly becoming a major news story, Steve Rogers, the erstwhile Captain America, assembles a group of legitimate Avengers in Brooklyn, New York City, to battle the Dark Avengers and help defend Asgard and aide their comrade Thor. At the same time the Avengers Resistance led by Tigra, Justice, and Gauntlet launch their own attack on Camp H.A.M.M.E.R., aimed at eliminating Osborn's Initiative.

Osborn's people offer Todd Keller, a conservative talk show host, exclusive official coverage of the siege, in order to mold public opinion. Meanwhile, longtime investigative journalist Ben Urich, editor of the New York City newspaper The Front Line, heads to the Oklahoma site of the battle with cameraman Will Stern. Volstagg, whom they meet in a chance encounter along the way, accompanies them and gives the reporters his own perspective.

As the battle in Asgard intensifies, the Greek god Ares, whom Osborn had deceptively recruited to his Dark Avengers, realizes the truth about Osborn, and vows to kill him. Osborn has the Sentry brutally kill Ares instead. Osborn declares martial law, just as Rogers and a contingent of Avengers arrive.^[5][6] Volstagg, with the aid of a local sheriff whose own suspicions about Osborn have been raised, speaks to the public via a webcam video, leading to the beginnings of public disenchantment with the increasingly volatile Osborn.

The siege continues with the supervillain Scourge using the enchanted spear of the Norse gods' ruler, Odin, to sever the left limbs of the superhero U.S. Agent.^[7] The conflicted hero Night Thrasher, who had been compelled to make a Faustian bargain with Osborn, turns on Osborn by battling Osborn's Cabal minion the Hood.^[8] In Washington, the President orders the Secretary of State to dispatch military forces to Oklahoma to have Osborn and the Dark Avengers arrested for treason. At that moment in Asgard, Osborn is struck down by Captain America's shield,^[9][10] yet manages to order the Sentry to destroy the infrastructure of Asgard. Sentry, having survived a flurry of brutal blows from Thor unscathed and on the verge of tearing Thor apart having transformed into the evil Void (which greatly multiplies his power to evolved heights) he leaves Thor and annihilates Asgard in a climactic moment in the battle, as he levels the floating city, bringing it crashing down to Earth.^[9][11] Captain America finds Osborn amid the wreckage, pulls him out and places him under arrest. Before anyone can react further, Osborn's armor, now under the control of its inventor, Tony Stark / Iron Man, explodes off his body on live television, revealing his face painted in the image of the Green Goblin. He begins raving that with he himself now powerless, he no longer has the leverage to control the Sentry, who is now fully possessed by his nihilistic other self, the Void.^[9]

As the Void battles the Avengers, Loki repents and begs Odin to let him use the mystical Norn Stones to power-boost the heroes and give them the strength to win the day. The Void, realizing that the heroes' enhanced power is being granted to them by Loki, kills Loki. Spurred on by Loki's sacrifice, Thor and the others battle the Void to a point that it reverting to the Sentry's human form. The Sentry begs the heroes to kill him, and Thor, after circumstances force his hand, regretfully complies, striking the Sentry down with a lightning blast that leaves only a charred skeleton.^[12] As Thor takes the Sentry's body to the sun, the New Avengers round up the Dark Avengers, Victoria Hand, the renegade members of the Initiative and the remaining members of the Cabal and others, and have them placed under arrest. Steve Rogers gives his former partner, Bucky Barnes, his Captain America shield, bequeathing Barnes the mantle.^[13]

As the Avengers and their allies celebrate their victory at their headquarters, Stark Tower, the Superhuman Registration Act is abolished. The President asks Steve Rogers to take over Osborn's position.^[12][14] A large group of heroes later attend the Sentry's memorial service.^[15] Rogers says he will continue the 50-State Initiative.^[16] He also assigns Victoria Hand to work with the reformed Avengers.^[13] U.S. Agent is made warden of the maximum security supervillain prison The Raft.^[17]

What if?[link]

In the special "What if..." series, the story "What if Osborn won the Siege of Asgard" is told. Ares gives in to his intuïtion before the Siege of Asgard, attacking Osborn in his own office after realising Osborn lied to him. Sentry murders Ares at the spot, but he is now able to rest up between battles, allowing him to head into battle fully powered. In turn, this leads to him being able to kill Thor as well as Captain America (by beheading him with his own shield). Most of the heroes present are subsequently slaughtered by the Dark Avengers (Bullseye kills Iron Man with a divine cannon, Daken kills Ben Grimm and Cyclops o.a.). Doom has himself and Emma Frost teleported out of battle, and comes up with a new strategy: Have Emma scan the Dark Avengers and find out the truth about Lindy's death. Bullseye is found out, and Emma asks Sentry to visit them, to show him the truth of what happens, with catastrophic results: Sentry's fragile psyche is shattered entirely, and he goes on a murderous rampage, killing both Frost and Bullseye straight off the bat, before transforming into a fully powered Void, who then kills Doom, Taskmaster, and the Hood. He then confronts Osborn, and thanks him for releasing him, only to kill him too. In the end, with the Avengers, Dark Avengers, and the gods all defeated, none were left to fight Sentry, and he eventually consumed planet earth, before spreading out to the rest of the Universe.

Picture of the siege of Rancagua during the Chilean War of Independence

A siege is a military blockade of a city or fortress with the intent of conquering by attrition or assault. The term derives from sedere, Latin for "to sit".^[1] Generally speaking, siege warfare is a form of constant, low intensity conflict characterized by one party holding a strong, static defensive position. Consequently, an opportunity for negotiation between combatants is not uncommon, as proximity and fluctuating advantage can encourage diplomacy.

A siege occurs when an attacker encounters a city or fortress that cannot be easily taken by a coup de main and refuses to surrender. Sieges involve surrounding the target and blocking the reinforcement or escape of troops or provision of supplies (a tactic known as "investment"^[2]), typically coupled with attempts to reduce the fortifications by means of siege engines, artillery bombardment, mining (also known as sapping), or the use of deception or treachery to bypass defences. Failing a military outcome, sieges can often be decided by starvation, thirst or disease, which can afflict either the attacker or defender.

Sieges probably predate the development of cities as large population centres. Ancient cities in the Middle East show archaeological evidence of having had fortified city walls. During the Warring States era of ancient China, there is both textual and archaeological evidence of prolonged sieges and siege machinery used against the defenders of city walls. Siege machinery was also a tradition of the ancient Greco-Roman world. During the Renaissance and the Early Modern period, siege warfare dominated the conduct of war in Europe. Leonardo da Vinci gained as much of his renown from the design of fortifications as from his artwork.

Medieval campaigns were generally designed around a succession of sieges. In the Napoleonic era, increasing use of ever more powerful cannon reduced the value of fortifications. In the 20th century, the significance of the classical siege declined. With the advent of mobile warfare, a single fortified stronghold is no longer as decisive as it once was. While traditional sieges do still occur, they are not as common as they once were due to changes in modes of battle, principally the ease by which huge volumes of destructive power can be directed onto a static target. Modern sieges are more commonly the result of smaller hostage, militant, or extreme resisting-arrest situations such as the Waco Siege.

Ancient era[link]

The necessity of city walls[link]

The Assyrians deployed large labour forces to build new palaces, temples and defensive walls.^[3] Some settlements in the Indus Valley Civilization were also fortified. By about 3500 BC, hundreds of small farming villages dotted the Indus River floodplain. Many of these settlements had fortifications and planned streets.

The stone and mud brick houses of Kot Diji were clustered behind massive stone flood dikes and defensive walls, for neighbouring communities quarreled constantly about the control of prime agricultural land.^[4] Mundigak (c. 2500 BC) in present-day southeast Afghanistan has defensive walls and square bastions of sun-dried bricks.^[3]

City walls and fortifications were essential for the defense of the first cities in the ancient Near East. The walls were built of mud bricks, stone, wood or a combination of these materials depending on local availability. They may also have served the dual purpose of showing presumptive enemies the might of the kingdom. The great walls surrounding the Sumerian city of Uruk gained a widespread reputation. The walls were 9.5 km (5.9 mi) in length, and up to 12 m (39 ft) in height.

Later the walls of Babylon, reinforced by towers and moats, gained a similar reputation. In Anatolia, the Hittites built massive stone walls around their cities, taking advantage of the hillsides. In Shang Dynasty China, at the site of Ao, large walls were erected in the 15th century BC that had dimensions of 20 m (66 ft) in width at the base and enclosed an area of some 2,100 yards (1,900 m) squared.^[5] The ancient Chinese capital for the State of Zhao, Handan, founded in 386 BC, also had walls that were 20 m (66 ft) wide at the base; they were 15 m (49 ft) tall, with two separate sides of its rectangular enclosure at a length of 1,530 yd (1,400 m).^[5]

The cities of the Indus Valley Civilization showed less effort in constructing defences, as did the Minoan civilization on Crete. These civilizations probably relied more on the defence of their outer borders or sea shores. Unlike the ancient Minoan civilization, the Mycenaean Greeks emphasized the need for fortifications alongside natural defenses of mountainous terrain, such as the massive Cyclopean walls built at Mycenae during the last half of the 2nd millennium BC.^{[citation needed]}

Archaeological evidence[link]

The Egyptian siege of Dapur in the 13th century BC, from Ramesseum, Thebes

Although there are depictions of sieges from the ancient Near East in historical sources and in art, there are very few examples of siege systems that have been found archaeologically. Of the few examples, several are noteworthy:

• The late 9th century BC siege system surrounding Tell es-Safi/Gath, Israel, consists of a 2.5 km long siege trench, towers and other elements, and is the earliest evidence of a circumvallation system known in the world. It was apparently built by Hazael of Aram Damascus, as part of his siege and conquest of Philistine Gath in the late 9th century BC (mentioned in II Kings 12:18).

• The late 8th century BC siege system surrounding the site of Lachish (Tell el-Duweir) in Israel, built by Sennacherib of Assyria in 701 BC, is not only evident in the archaeological remains, but is described in Assyrian and biblical sources and in the reliefs of Sennacherib's palace in Nineveh.

• The siege of Alt-Paphos, Cyprus by the Persian army in the 4th century BC.

Depictions[link]

The earliest representations of siege warfare have been dated to the Protodynastic Period of Egypt, c. 3000 BC. These show the symbolic destruction of city walls by divine animals using hoes.

The first siege equipment is known from Egyptian tomb reliefs of the 24th century BC, showing Egyptian soldiers storming Canaanite town walls on wheeled siege ladders. Later Egyptian temple reliefs of the 13th century BC portray the violent siege of Dapur, a Syrian city, with soldiers climbing scale ladders supported by archers.

Assyrian palace reliefs of the 9th to 7th centuries BC display sieges of several Near Eastern cities. Though a simple battering ram had come into use in the previous millennium, the Assyrians improved siege warfare and used huge wooden tower-shaped battering rams with archers positioned on top.

In ancient China, sieges of city walls (along with naval battles) were portrayed on bronze 'hu' vessels, like those found in Chengdu, Sichuan in 1965 which have been dated to the Warring States Period (5th century BC to 3rd century BC).^[6]

Tactics[link]

Offensive[link]

Depiction of various siege machines in the mid-16th c.

The most common practice of siege warfare was to lay siege and just wait for the surrender of the enemies inside, or quite commonly, to coerce someone inside to betray the fortification. During a siege a surrounding army would build earthworks (a line of circumvallation) to completely encircle their target, preventing food, water, and other supplies from reaching the besieged city. If sufficiently desperate as the siege progressed, defenders and civilians might have been reduced to eating anything vaguely edible - horses, family pets, the leather from shoes, and even each other.

The Egyptian siege of Megiddo in the 15th century BC lasted for 7 months before its inhabitants surrendered. The Hittite siege of a rebellious Anatolian vassal in the 14th century BC ended when the queen mother came out of the city and begged for mercy on behalf of her people. The Hittite campaign against the kingdom of Mitanni in the 14th century BC bypassed the fortified city of Carchemish. If the main objective of a campaign was not the conquest of a particular city, it could simply be passed by. When the main objective of the campaign had been fulfilled, the Hittite army returned to Carchemish and the city fell after an eight-day siege.

The well-known Assyrian Siege of Jerusalem in the 8th century BC came to an end when the Israelites bought them off with gifts and tribute, according to the Assyrian account, or when the Assyrian camp was struck by mass death, according to the Biblical account. Due to logistics, long-lasting sieges involving a minor force could seldom be maintained.

To end a siege more rapidly various methods were developed in ancient and medieval times to counter fortifications, and a large variety of siege engines were developed for use by besieging armies. Ladders could be used to escalade over the defences. Battering rams and siege hooks could also be used to force through gates or walls, while catapults, ballistae, trebuchets, mangonels, and onagers could be used to launch projectiles in order to break down a city's fortifications and kill its defenders. A siege tower, a substantial structure built to equal or greater height than the fortification's walls, could allow the attackers to fire down upon the defenders and also advance troops to the wall with less danger than using ladders.

Medieval trebuchets could sling about two projectiles per hour at enemy positions.

In addition to launching projectiles at the fortifications or defenders, it was also quite common to attempt to undermine the fortifications, causing them to collapse. This could be accomplished by digging a tunnel beneath the foundations of the walls, and then deliberately collapsing or exploding the tunnel. This process is known as mining. The defenders could dig counter-tunnels to cut into the attackers' works and collapse them prematurely.

Fire was often used as a weapon when dealing with wooden fortifications. The Byzantine Empire used Greek fire, which contained additives that made it hard to extinguish. Combined with a primitive flamethrower, it proved an effective offensive and defensive weapon.^[7]

Disease was another effective siege weapon, although the attackers were often as vulnerable as the defenders. In some instances, catapults or similar weapons were used to fling diseased animals over city walls in an early example of biological warfare. If all else failed, a besieger could claim the booty of his conquest undamaged, and retain his men and equipment intact, for the price of a well-placed bribe to a disgruntled gate-keeper.

Defensive[link]

The universal method for defending against siege is the use of fortifications, principally walls and ditches to supplement natural features. A sufficient supply of food and water was also important to defeat the simplest method of siege warfare: starvation. On occasion, the defenders would drive 'surplus' civilians out to reduce the demands on stored food and water.^[8]

During the Warring States Period in China (481–221 BC), warfare lost its honorable, gentlemen's duty that was found in the previous era of the Spring and Autumn Period, and became more practical, competitive, cut-throat, and efficient for gaining victory.^[9] The Chinese invention of the hand-held, trigger-mechanism crossbow during this period revolutionized warfare, giving greater emphasis to infantry and cavalry and less to traditional chariot warfare.

The philosophically-pacifist Mohists (followers of the philosopher Mozi) of the 5th century BC believed in aiding the defensive warfare of smaller Chinese states against the hostile offensive warfare of larger domineering states. The Mohists were renowned in the smaller states (and the enemies of the larger states) for the inventions of siege machinery to scale or destroy walls. These included traction trebuchet catapults, eight-foot-high ballistas, a wheeled siege ramp with grappling hooks known as the Cloud Bridge (the protractable, folded ramp slinging forward by means of a counterweight with rope and pulley), and wheeled 'hook-carts' used to latch large iron hooks onto the tops of walls to pull them down.^[10]

Cahir Castle in Ireland was besieged and captured three times: in 1599 by the Earl of Essex, in 1647 by Lord Inchiquin, and in 1650 by Oliver Cromwell.

When enemies attempted to dig tunnels under walls for mining or entry into the city, the defenders used large bellows (the type the Chinese commonly used in heating up a blast furnace for smelting cast iron) to pump smoke into the tunnels in order to suffocate the intruders.^[9]

Advances in the prosecution of sieges in ancient and medieval times naturally encouraged the development of a variety of defensive counter-measures. In particular, medieval fortifications became progressively stronger—for example, the advent of the concentric castle from the period of the Crusades—and more dangerous to attackers—witness the increasing use of machicolations and murder-holes, as well the preparation of hot or incendiary substances.^[11] Arrow slits (also called arrow loops or loopholes), sally ports (airlock-like doors) for sallies, and deep water wells were also integral means of resisting siege at this time. Particular attention would be paid to defending entrances, with gates protected by drawbridges, portcullises and barbicans. Moats and other water defences, whether natural or augmented, were also vital to defenders.^[12]

In the European Middle Ages, virtually all large cities had city walls—Dubrovnik in Dalmatia is an impressive and well-preserved example—and more important cities had citadels, forts or castles. Great effort was expended to ensure a good water supply inside the city in case of siege. In some cases, long tunnels were constructed to carry water into the city. Complex systems of underground tunnels were used for storage and communications in medieval cities like Tábor in Bohemia, similar to those used much later in Vietnam during the Vietnam War.^{[citation needed]}

Until the invention of gunpowder-based weapons (and the resulting higher-velocity projectiles), the balance of power and logistics definitely favored the defender. With the invention of gunpowder, cannon and (in modern times) mortars and howitzers, the traditional methods of defence became less effective against a determined siege.^[13]

Siege accounts[link]

Although there are numerous ancient accounts of cities being sacked, few contain any clues to how this was achieved. Some popular tales existed on how the cunning heroes succeeded in their sieges. The best-known is the Trojan Horse of the Trojan War, and a similar story tells how the Canaanite city of Joppa was conquered by the Egyptians in the 15th century BC. The Biblical Book of Joshua contains the story of the miraculous Battle of Jericho.

A more detailed historical account from the 8th century BC, called the Piankhi stela, records how the Nubians laid siege to and conquered several Egyptian cities by using battering rams, archers, and slingers and building causeways across moats.

Greco-Roman era[link]

Alexander the Great's Macedonian army successfully besieged many powerful cities during his astounding conquests. Two of his most impressive achievements in siegecraft took place in the Siege of Tyre and the Siege of the Sogdian Rock. His engineers built a causeway that was originally 60 m (200 ft) wide and reached the range of his torsion-powered artillery, while his soldiers pushed siege towers housing stone throwers and light catapults to bombard the city walls.

Most conquerors before him had found Tyre, a Phoenician island-city about 1 km from the mainland, impregnable. The Macedonians built a mole, a raised spit of earth across the water, by piling stones up on a natural land bridge that extended underwater to the island, and although the Tyrians rallied by sending a fire-ship to destroy the towers, and captured the mole in a swarming frenzy, the city eventually fell to the Macedonians after a seven-month siege. In complete contrast to Tyre, Sogdian Rock was captured by stealthy attack. Alexander used commando-like tactics to scale the cliffs and capture the high ground, and the demoralized defenders surrendered.

Roman siege machines.

The importance of siege warfare in the ancient period should not be underestimated. One of the contributing causes of Hannibal's inability to defeat Rome was his lack of a siege train, thus, while he was able to defeat Roman armies in the field, he was unable to capture Rome itself. The legionary armies of the Roman Republic and Empire are noted as being particularly skilled and determined in siege warfare. An astonishing number and variety of sieges, for example, formed the core of Julius Caesar's mid-1st century BC conquest of Gaul (modern France).

In his Commentarii de Bello Gallico (Commentaries on the Gallic War), Caesar describes how at the Battle of Alesia the Roman legions created two huge fortified walls around the city. The inner circumvallation, 10 miles (16 km), held in Vercingetorix's forces, while the outer contravallation kept relief from reaching them. The Romans held the ground in between the two walls. The besieged Gauls, facing starvation, eventually surrendered after their relief force met defeat against Caesar's auxiliary cavalry.

The Sicarii Zealots who defended Masada in AD 73 were defeated by the Roman legions who built a ramp 100 m high up to the fortress's west wall.

Chinese and Mongols[link]

In the Middle Ages, the Mongol Empire's campaign against China (then comprising the Western Xia Dynasty, Jin Dynasty, and Southern Song Dynasty) by Genghis Khan until Kublai Khan, who eventually established the Yuan Dynasty in 1271, with their armies was extremely effective, allowing the Mongols to sweep through large areas. Even if they could not enter some of the more well-fortified cities, they used innovative battle tactics to grab hold of the land and the people:

"By concentrating on the field armies, the strongholds had to wait. Of course, smaller fortresses, or ones easily surprised, were taken as they came along. This had two effects. First, it cut off the principal city from communicating with other cities where they might expect aid. Secondly, refugees from these smaller cities would flee to the last stronghold. The reports from these cities and the streaming hordes of refugees not only reduced the morale of the inhabitants and garrison of the principal city, it also strained their resources. Food and water reserves were taxed by the sudden influx of refugees. Soon, what was once a formidable undertaking became easy. The Mongols were then free to lay siege without interference of the field army as it had been destroyed... At the siege of Aleppo, Hulegu used twenty catapults against the Bab al-Iraq (Gate of Iraq) alone.^[14] In Jûzjânî, there are several episodes in which the Mongols constructed hundreds of siege machines in order to surpass the number which the defending city possessed. While Jûzjânî surely exaggerated, the improbably high numbers which he used for both the Mongols and the defenders do give one a sense of the large numbers of machines used at a single siege."^{[citation needed]}

Another Mongol tactic was to use catapults to launch corpses of plague victims into besieged cities. The disease-carrying fleas from the bodies would then infest the city, and the plague would spread allowing the city to be easily captured, although this transmission mechanism was not known at the time. In 1346 the bodies of Mongol warriors of the Golden Horde who had died of plague were thrown over the walls of the besieged Crimean city of Kaffa (now Feodosiya). It has been speculated that this operation may have been responsible for the advent of the Black Death in Europe.^[15] The Black Death is estimated to have killed 30% – 60% of Europe's population.^[16]

On the first night while laying siege to a city, the leader of the Mongol forces would lead from a white tent: if the city surrendered, all would be spared. On the second day, he would use a red tent: if the city surrendered, the men would all be killed, but the rest would be spared. On the third day, he would use a black tent: no quarter would be given.^[17]

Chinese and Korean troops assault the Japanese forces of Hideyoshi in the Siege of Ulsan Castle during the Imjin War (1592–1598).

However, the Chinese were not completely defenceless, and from AD 1234 until 1279 the Southern Song Chinese held out against the enormous barrage of Mongol attacks. Much of this success in defense lay in the world's first use of gunpowder (i.e. with early flamethrowers, grenades, firearms, cannons, and land mines) to fight back against the Khitans, the Tanguts, the Jurchens, and then the Mongols.

The Chinese of the Song period also discovered the explosive potential of packing hollowed cannonball shells with gunpowder. Written later around 1350 in the Huo Long Jing, this manuscript of Jiao Yu recorded an earlier Song-era cast-iron cannon known as the 'flying-cloud thunderclap eruptor' (fei yun pi-li pao). The manuscript stated that (Wade-Giles spelling):

The shells (phao) are made of cast iron, as large as a bowl and shaped like a ball. Inside they contain half a pound of 'magic' gunpowder (shen huo). They are sent flying towards the enemy camp from an eruptor (mu phao); and when they get there a sound like a thunder-clap is heard, and flashes of light appear. If ten of these shells are fired successfully into the enemy camp, the whole place will be set ablaze...^[18]

During the Ming Dynasty (AD 1368–1644), the Chinese were very concerned with city planning in regards to gunpowder warfare. The site for constructing the walls and the thickness of the walls in Beijing's Forbidden City were favored by the Chinese Yongle Emperor (r. 1402–1424), because they were in pristine position to resist cannon volley and were built thick enough to withstand attacks from cannon fire.^{[citation needed]}

Age of gunpowder[link]

Turks laid siege to Constantinople for nearly two months in 1453. Other sieges lasted much longer.

The introduction of gunpowder and the use of cannons brought about a new age in siege warfare. Cannons were first used in Song Dynasty China during the early 13th century, but did not become significant weapons for another 150 years or so. By the 16th century, they were an essential and regularized part of any campaigning army, or castle's defences.

The greatest advantage of cannons over other siege weapons was the ability to fire a heavier projectile, further, faster and more often than previous weapons. They could also fire projectiles in a straight line, so that they could destroy the bases of high walls. Thus, 'old fashioned' walls - that is high and, relatively, thin - were excellent targets and, over time, easily demolished. In 1453, the great walls of Constantinople, the capital of the Byzantine Empire, were broken through in just six weeks by the 62 cannons of Mehmet II's army.

However, new fortifications, designed to withstand gunpowder weapons, were soon constructed throughout Europe. During the Renaissance and the Early Modern period, siege warfare continued to dominate the conduct of the European wars.

Once siege guns were developed the techniques for assaulting a town or a fortress became well known and ritualized. The attacking army would surround a town. Then the town would be asked to surrender. If they did not comply the besieging army would surround the town with temporary fortifications to stop sallies from the stronghold or relief getting in. The attackers would then build a length of trenches parallel to the defences and just out of range of the defending artillery. They would then dig a trench towards the town in a zigzag pattern so that it could not be enfiladed by defending fire. Once within artillery range another parallel trench would be dug with gun emplacements. This was called sapping.

If necessary using the first artillery fire for cover this process would be repeated until guns were close enough to be laid accurately to make a breach in the fortifications. In order to allow the forlorn hope and support troops to get close enough to exploit the breach, more zigzag trenches could be dug even closer to the walls with more parallel trenches to protect and conceal the attacking troops. After each step in the process the besiegers would ask the besieged to surrender. If the forlorn hope stormed the breach successfully the defenders could expect no mercy.

Emerging theories[link]

The castles that in earlier years had been formidable obstacles were easily breached by the new weapons. For example, in Spain, the newly equipped army of Ferdinand and Isabella was able to conquer Moorish strongholds in Granada in 1482–92 that had held out for centuries before the invention of cannons.

In the early 15th century, Italian architect Leon Battista Alberti wrote a treatise entitled De Re aedificatoria which theorized methods of building fortifications capable of withstanding the new guns. He proposed that walls be "built in uneven lines, like the teeth of a saw." He proposed star-shaped fortresses with low thick walls.

However, few rulers paid any attention to his theories. A few towns in Italy began building in the new style late in the 1480s, but it was only with the French invasion of the Italian peninsula in 1494–95 that the new fortifications were built on a large scale. Charles VIII invaded Italy with an army of 18,000 men and a horse-drawn siege-train. As a result he could defeat virtually any city or state, no matter how well defended. In a panic, military strategy was completely rethought throughout the Italian states of the time, with a strong emphasis on the new fortifications that could withstand a modern siege.

New fortresses[link]

The most effective way to protect walls against cannon fire proved to be depth (increasing the width of the defences) and angles (ensuring that attackers could only fire on walls at an oblique angle, not square on). Initially walls were lowered and backed, in front and behind, with earth. Towers were reformed into triangular bastions.^[19] This design matured into the trace italienne. Star-shaped fortresses surrounding towns and even cities with outlying defences proved very difficult to capture, even for a well equipped army.^[20] Fortresses built in this style throughout the 16th century did not become fully obsolete until the 19th century, and were still in use throughout World War I (though modified for 20th century warfare). During World War II trace italienne fortresses could still present a formidable challenge, for example in the last days of World War II, during the Battle in Berlin that saw some of the heaviest urban fighting of the war, the Soviets did not attempt to storm the Spandau Citadel (built between 1559 and 1594) but chose to invest it and negotiate its surrender.^[21]

However, the cost of building such vast modern fortifications was incredibly high, and was often too much for individual cities to undertake. Many were bankrupted in the process of building them; others, such as Siena, spent so much money on fortifications that they were unable to maintain their armies properly, and so lost their wars anyway. Nonetheless, innumerable large and impressive fortresses were built throughout northern Italy in the first decades of the 16th century to resist repeated French invasions that became known as the Italian Wars. Many stand to this day.

In the 1530s and 1540s, the new style of fortification began to spread out of Italy into the rest of Europe, particularly to France, the Netherlands, and Spain. Italian engineers were in enormous demand throughout Europe, especially in war-torn areas such as the Netherlands, which became dotted by towns encircled in modern fortifications. The densely populated areas of Northern Italy and the United Provinces (the Netherlands) were infamous for their high degree of fortification of cities. It made campaigns in these areas very hard to successfully conduct, considering even minor cities had to be captured by siege within the span of the campaigning season. In the Dutch case, the possibility of flooding large parts of the land provided an additional obstacle to besiegers, for example at the Siege of Leiden. For many years, defensive and offensive tactics were well balanced leading to protracted and costly wars such as Europe had never known, involving more and more planning and government involvement. The new fortresses ensured that war rarely extended beyond a series of sieges. Because the new fortresses could easily hold 10,000 men, an attacking army could not ignore a powerfully fortified position without serious risk of counterattack. As a result, virtually all towns had to be taken, and that was usually a long, drawn-out affair, potentially lasting from several months to years, while the members of the town were starved to death. Most battles in this period were between besieging armies and relief columns sent to rescue the besieged.

Marshal Vauban and Van Coehoorn[link]

Vauban refined siege warfare by designing fortresses to withstand attacks and planning attacks.

At the end of the 17th century, two influential military engineers, the French Marshal Vauban and the Dutch military engineer Menno van Coehoorn, developed modern fortification to its pinnacle, refining siege warfare without fundamentally altering it: ditches would be dug; walls would be protected by glacis; and bastions would enfilade an attacker. Both engineers developed their ideas independently but came to similar general rules regarding defensive construction and offensive action against fortifications. Both were skilled in conducting sieges and defences themselves. Before Vauban and Van Coehoorn, sieges had been somewhat slapdash operations. Vauban and Van Coehoorn refined besieging to a science with a methodical process that, if uninterrupted, would break even the strongest fortifications. Examples of their styles of fortifications are Arras (Vauban) and the no-longer existent fortress of Bergen op Zoom (Van Coehoorn). The main differences between the two lay in the difference in terrain on which Vauban and Van Coehoorn constructed their defences: Vauban in the sometimes more hilly and mountainous terrain of France, Van Coehoorn in the flat and floodable lowlands of the Netherlands.

Planning and maintaining a siege is just as difficult as fending one off. A besieging army must be prepared to repel both sorties from the besieged area and also any attack that may try to relieve the defenders. It was thus usual to construct lines of trenches and defenses facing in both directions. The outermost lines, known as the lines of contravallation, would surround the entire besieging army and protect it from attackers.

Vauban's star-shaped fortified city of Neuf-Brisach.

This would be the first construction effort of a besieging army, built soon after a fortress or city had been invested. A line of circumvallation would also be constructed, facing in towards the besieged area, to protect against sorties by the defenders and to prevent the besieged from escaping. The next line, which Vauban usually placed at about 600 meters from the target, would contain the main batteries of heavy cannons so that they could hit the target without being vulnerable themselves. Once this line was established, work crews would move forward creating another line at 250 meters. This line contained smaller guns. The final line would be constructed only 30 to 60 meters from the fortress. This line would contain the mortars and would act as a staging area for attack parties once the walls were breached. Van Coehoorn developed a small and easily movable mortar named the coehorn, variations of which were used in sieges until the nineteenth century. It would also be from this line that miners working to undermine the fortress would operate.

The trenches connecting the various lines of the besiegers could not be built perpendicular to the walls of the fortress, as the defenders would have a clear line of fire along the whole trench. Thus, these lines (known as saps) needed to be sharply jagged.

The Battle of Vienna took place in 1683 after Vienna had been besieged by the Ottoman Empire for two months.

Another element of a fortress was the citadel. Usually a citadel was a "mini fortress" within the larger fortress, sometimes designed as a reduit, but more often as a means of protecting the garrison from potential revolt in the city. The citadel was used in wartime and peacetime to keep the residents of the city in line.

As in ages past, most sieges were decided with very little fighting between the opposing armies. An attacker's army was poorly served incurring the high casualties that a direct assault on a fortress would entail. Usually they would wait until supplies inside the fortifications were exhausted or disease had weakened the defenders to the point that they were willing to surrender. At the same time, diseases, especially typhus were a constant danger to the encamped armies outside the fortress, and often forced a premature retreat. Sieges were often won by the army that lasted the longest.

An important element of strategy for the besieging army was whether or not to allow the encamped city to surrender. Usually it was preferable to graciously allow a surrender, both to save on casualties, and to set an example for future defending cities. A city that was allowed to surrender with minimal loss of life was much better off than a city that held out for a long time and was brutally butchered at the end. Moreover, if an attacking army had a reputation of killing and pillaging regardless of a surrender, then other cities' defensive efforts would be redoubled. Usually a city would surrender (with no honour lost) when its inner lines of defence were reached by the attacker. In case of refusal however, the inner lines would have to be stormed by the attacker and the attacking troops would be justified in sacking the city.

Mobile warfare[link]

Siege warfare dominated in Western Europe for most of the seventeenth and eighteenth centuries. An entire campaign, or longer, could be used in a single siege (for example, Ostend in 1601–04; La Rochelle in 1627–28). This resulted in extremely prolonged conflicts. The balance was that while siege warfare was extremely expensive and very slow, it was very successful—or, at least, more so than encounters in the field. Battles arose through clashes between besiegers and relieving armies, but the principle was a slow grinding victory by the greater economic power. The relatively rare attempts at forcing pitched battles (Gustavus Adolphus in 1630; the French against the Dutch in 1672 or 1688) were almost always expensive failures.

Storming of Redoubt #10 during the Siege of Yorktown

The exception to this rule were the English.^[22] During the English Civil War anything which tended to prolong the struggle, or seemed like want of energy and avoidance of a decision, was bitterly resented by the men of both sides. In France and Germany, the prolongation of a war meant continued employment for the soldiers, but in England both sides were looking to end the war quickly. Even when in the end the New Model Army—a regular professional army—developed the original decision-compelling spirit permeated the whole organisation as was seen when pitched against regular professional continental troops the Battle of the Dunes during the Interregnum.^[23]

British infantry attempt to scale the walls of Badajoz, Peninsular War, 1812

Experienced commanders on both sides in the English Civil War recommended the abandonment of garrisoned fortifications for two primary reasons. The first, as for example proposed by the Royalist Sir Richard Willis to King Charles, was that by abandoning the garrisoning of all but the most strategic locations in ones own territory, far more troops would be available for the field armies and it was the field armies which would decide the conflict. The other argument was that by slighting potential strong points in ones own territory, an enemy expeditionary force, or local enemy rising, would find it more difficult to consolidate territorial gains against an inevitable counter attack. Sir John Meldrum put forward just such an argument to the Parliamentary Committee of Both Kingdoms, to justify his slighting of Gainsborough in Lincolnshire.^[24][25]

Sixty years later during the War of the Spanish Succession the Duke of Marlborough preferred to engage the enemy in pitched battles rather than engage in siege warfare, although he was very proficient in both types of warfare.

On 15 April 1746, the day before the Battle of Culloden, at Dunrobin Castle, a party of the William Sutherland, 17th Earl of Sutherland’s militia conducted the last siege fought on the mainland of Great Britain against Jacobin members of clan MacLeod.

Strategic concepts[link]

In the French Revolutionary and Napoleonic Wars, new techniques stressed the division of armies into all-arms corps that would march separately and only come together on the battlefield. The less concentrated army could now live off the country and move more rapidly over a larger number of roads.

Fortresses commanding lines of communication could be bypassed and would no longer stop an invasion. Since armies could not live off the land indefinitely, Napoleon Bonaparte always sought a quick end to any conflict by pitched battle. This military revolution was described and codified by Clausewitz.

Industrial advances[link]

French Engineer Corps during the Siege of Antwerp.

Advances in artillery made previously impregnable defenses useless. For example, the walls of Vienna that had held off the Turks in the mid-seventeenth century were no obstacle to Napoleon in the late eighteenth.

Where sieges occurred (such as the Siege of Delhi and the Siege of Cawnpore during the Indian Rebellion of 1857), the attackers were usually able to defeat the defenses within a matter of days or weeks, rather than weeks or months as previously. The great Swedish white-elephant fortress of Karlsborg was built in the tradition of Vauban and intended as a reserve capital for Sweden, but it was obsolete before it was completed in 1869.

Railways, when they were introduced, made possible the movement and supply of larger armies than those that fought in the Napoleonic Wars. It also reintroduced siege warfare, as armies seeking to use railway lines in enemy territory were forced to capture fortresses which blocked these lines.

During the Franco-Prussian War, the battlefield front-lines moved rapidly through France. However, the Prussian and other German armies were delayed for months at the Siege of Metz and the Siege of Paris, due to the greatly increased firepower of the defending infantry, and the principle of detached or semi-detached forts with heavy-caliber artillery. This resulted in the later construction of fortress works across Europe such as the massive fortifications at Verdun. It also led to the introduction of tactics which sought to induce surrender by bombarding the civilian population within a fortress rather than the defending works themselves.

The Siege of Sevastopol (1854–1855) during the Crimean War and the Siege of Petersburg (1864–1865) during the American Civil War showed that modern citadels, when improved by improvised defences, could still resist an enemy for many months. The Siege of Plevna during the Russo-Turkish War (1877–1878) proved that hastily-constructed field defences could resist attacks prepared without proper resources, and were a portent of the trench warfare of World War I.

Advances in firearms technology without the necessary advances in battlefield communications gradually led to the defense again gaining the ascendancy. An example of siege during this time, prolonged during 337 days due to the isolation of the surrounded troops, was the Siege of Baler, in which a reduced group of Spanish soldiers, was besieged in a small church by the Philippine rebels, in the course of the Philippine Revolution and the Spanish-American War, until months after the Treaty of Paris, the end of the conflict.

Furthermore, the development of steamships availed greater speed to blockade runners, ships with the purpose of bringing cargo, e.g. food, to cities under blockade, as with Charleston, South Carolina during the American Civil War.

Modern warfare[link]

This sepoy POW shows the conditions of the garrison at Kut at the end of the siege in the First World War.

Mainly as a result of the increasing firepower (such as machine guns) available to defensive forces, First World War trench warfare briefly revived a form of siege warfare. Although siege warfare had moved out from an urban setting because city walls had become ineffective against modern weapons, trench warfare was nonetheless able to use many of the techniques of siege warfare in its prosecution (sapping, mining, barrage and, of course, attrition) but on a much larger scale and on a greatly extended front.

More traditional sieges of fortifications took place in addition to trench sieges. The Siege of Tsingtao was one of the first major sieges of the war, but the inability for significant resupply of the German garrison made it a relatively one-sided battle. The Germans and the crew of an Austro-Hungarian protected cruiser put up a hopeless defense and after holding out for more than a week surrendered to the Japanese, forcing the German East Asia Squadron to steam towards South America for a new coal source.

The other major siege outside Europe during the First World War was in Mesopotamia, at the Siege of Kut. After a failed attempt to move on Baghdad, stopped by the Ottomans at the bloody Battle of Ctesiphon, the British and their large contingent of Indian sepoy soldiers were forced to retreat to Kut, where the Ottomans under German General Baron Colmar von der Goltz laid siege. The British attempts to resupply the force via the Tigris river failed, and rationing was complicated by the refusal of many Indian troops to eat cattle products. By the time the garrison fell on 29 April 1916, starvation was rampant. Conditions did not improve greatly under Turkish imprisonment. Along with the Battle of Tanga, the Battle of Sandfontein, the Battle of Gallipoli and the Battle of Namakura, it would be one of Britain's numerous embarrassing colonial defeats of the war.

The Skoda 305 mm Model 1911.

The largest sieges of the war, however, took place in Europe. The initial German advance into Belgium produced four major sieges, the Battle of Liege, the Battle of Namur, the Siege of Maubeuge and the Siege of Antwerp. All three would prove crushing German victories, at Liege and Namur against the Belgians, at Maubeuge against the French and at Antwerp against a combined Anglo-Belgian force. The weapon that made these victories possible were the German Big Berthas and the Skoda 305 mm Model 1911 siege mortars, one of the best siege mortars of the war,^[26] on loan from Austria-Hungary. These huge guns were the decisive weapon of siege warfare in the 20th century, taking part at Przemysl, the Belgian sieges, on the Italian Front and Serbian Front, and even being reused in World War II.

At the second Siege of Przemysl, the Austro-Hungarian garrison showed an excellent knowledge of siege warfare, not only waiting for relief, but sending sorties into Russian lines and employing an active defense that resulted in the capture of the Russian General Lavr Kornilov. Despite its excellent performance, the garrison's food supply had been requisitioned for earlier offensives, a relief expedition was stalled by the weather, ethnic rivalries flared up between the defending soldiers and a breakout attempt failed. When the commander of the garrison Hermann Kusmanek finally surrendered, his troops were eating their horses and the first attempt of large-scale air supply had failed. It was one of the few great victories obtained by either side during the war; 110,000 Austro-Hungarian prisoners were marched back to Russia. Use of aircraft for siege running, bringing supplies to areas under siege, would nevertheless prove useful in many sieges to come.

The largest siege of the war, and the arguably the roughest, most gruesome battle in history, was the Battle of Verdun. Whether the battle can be considered true siege warfare is debatable. Under the theories of Erich von Falkenhayn it is more distinguishable as purely attrition with a coincidental presence of fortifications on the battlefield. When considering the plans of Crown Prince Wilhelm, purely concerned with taking the citadel and not with French casualty figures, it can be considered a true siege. The main fortifications were Fort Douaumont, Fort Vaux and the fortified city of Verdun itself. The Germans, through the use of huge artillery bombardments, flamethrowers and infiltration tactics were able to capture both Vaux and Douaumont, but were never able to take the city, and eventually lost most of their gains. It was a battle that, despite the French ability to fend off the Germans, neither side won. The German losses were not worth the potential capture of the city and the French casualties were not worth holding the symbol of her defense.

The development of the armoured tank and improved infantry tactics at the end of World War I swung the pendulum back in favour of maneuver, and with the advent of Blitzkrieg in 1939, the end of traditional siege warfare was at hand. The Maginot Line would be the prime example of the failure of immobile, post–World War I fortifications. Although sieges would continue, it would be in a totally different style and on a reduced scale.

Second World War[link]

The Blitzkrieg of the Second World War truly showed that fixed fortifications are easily defeated by maneuver instead of frontal assault or long sieges. The great Maginot Line was bypassed and battles that would have taken weeks of siege could now be avoided with the careful application of air power (such as the German paratrooper capture of Fort Eben-Emael, Belgium, early in World War II).

The most important siege was the Siege of Leningrad, that lasted over 29 months, about half of the duration of the entire Second World War. Along with the Battle of Stalingrad, the Siege of Leningrad on the Eastern Front was the deadliest siege of a city in history. In the west, apart from the Battle of the Atlantic the sieges were not on the same scale as those on the European Eastern front; however, there were several notable or critical sieges: the island of Malta, for which the population won the George Cross, Tobruk. In the South-East Asian Theatre there was the siege of Singapore and in the Burma Campaign sieges of Myitkyina, the Admin Box, Imphal and Kohima which was the high-water mark for the Japanese advance into India.

The siege of Sevastopol saw the use of the heaviest and most powerful individual siege engines ever to be used: the German 800mm railway gun and the 600mm siege mortar. Though a single shell could have disastrous local effect, the guns were susceptible to air attack in addition to being slow to move.

The airbridge methods which were developed and used extensively in the Burma Campaign for supplying the Chindits and other units, including those in sieges such as Imphal, as well as flying the Hump into China, allowed the western powers to develop air lift expertise which would prove vital during the Cold War Berlin Blockade. Air supply failed to prevent the fall of Dien Bien Phu to the Vietnamese in 1954 but proved crucial in maintaining the American base at Khe Sanh in 1968.

Post Second World War[link]

French troops seeking cover in trenches, Dien Bien Phu, 1954

During the Vietnam War the battles of Dien Bien Phu (1954) and Khe Sanh (1968) possessed siege-like characteristics. In both cases, the Viet Minh and NLF were able to cut off the opposing army by capturing the surrounding rugged terrain.^[27] At Dien Bien Phu, the French were unable to use air power to overcome the siege and were defeated.^[28] However, at Khe Sanh a mere 14 years later, advances in air power allowed the United States to withstand the siege. The resistance of US forces was assisted by the PAVN and PLAF forces' decision to use the Khe Sanh siege as a strategic distraction to allow their mobile warfare offensive, the first Tet Offensive, to unfold securely.

The Siege of Khe Sanh displays typical features of modern sieges, as the defender has greater capacity to withstand the siege, the attacker's main aim is to bottle operational forces or create a strategic distraction, rather than take the siege to a conclusion. In neighboring Cambodia, at that time known as the Khmer Republic, the Khmer Rouge used siege tactics to cut off supplies from Phnom Penh to other government-held enclaves in an attempt to break the will of the government to continue fighting.

In 1972 the Easter offensive, the Siege of An Loc Vietnam occurred. ARVN troops and U.S. advisers and air power successfully defeated communist forces. The Battle of An Loc pitted some 6,350 ARVN men against a force three times that size. During the peak of the battle, ARVN had access to only one 105 mm howitzer to provide close support while the enemy attack was backed by an entire artillery division. ARVN had no tanks, the NVA communist forces had two armored regiments. ARVN prevailed after over two month of continuous fighting. As General Paul Vanuxem, a French veteran of the Indochina War, wrote in 1972 after visiting the liberated city of An Loc: "An Loc was the Verdun of Vietnam, where Vietnam received as in baptism the supreme consecration of her will."

Police activity[link]

Siege tactics continue to be employed in police conflicts. This has been due to a number of factors, primarily risk to life, whether that of the police, the besieged, bystanders or hostages. Police make use of trained negotiators, psychologists and, if necessary, force, generally being able to rely on the support of their nation's armed forces if required.

One of the complications facing police in a siege involving hostages is the Stockholm syndrome where sometimes hostages can develop a sympathetic rapport with their captors. If this helps keep them safe from harm this is considered to be a good thing, but there have been cases where hostages have tried to shield the captors during an assault or refused to co-operate with the authorities in bringing prosecutions.

The 1993 police siege on the Branch Davidian church in Waco, Texas, lasted 51 days, an atypically long police siege. Unlike traditional military sieges, police sieges tend to last for hours or days rather than weeks, months or years.

In Britain, if the siege involves perpetrators who are considered by the British Government to be terrorists, and if an assault is to take place, the civilian authorities hand command and control over to the military. The threat of such an action ended the Balcombe Street Siege in 1975 but the Iranian Embassy Siege in 1980 ended in a military assault and the deaths of all but one of the hostage takers.

Gilberto Hernández (/hiːlˈbɛərtoʊ/ heel-BAIR-toh; Spanish pronunciation: [xilˈβerto]; born February 1, 1957; usually credited as Gilbert Hernandez and also known by the nickname Beto (Spanish pronunciation: [ˈbeto])), is an American cartoonist. He best known for his Heartbreak Soup stories in Love and Rockets, an alternative comic book he shared with his brothers Jaime and Mario.

Early life[link]

Hernández grew up in Oxnard, California, in a family of five brothers and one sister.^[1] He was exposed to comic books early in life through his mother, who passed on her love of the medium to her children. He was particularly enamored with the work that Jack Kirby and Steve Ditko produced for Marvel Comics, as well as Hank Ketcham's Dennis the Menace and the Archie comics line. His brother Mario was responsible for introducing Gilbert to the underground comix movement when he smuggled a copy of Zap Comix into the house. Another big influence on Hernández's work has been rock music, including punk, new wave and glitter rock. In particular, the "Brothers Hernández" were influenced by the energy and diversity of the late 1970s California punk and hardcore scene. Hernández has credited punk rock with giving him the confidence to start drawing his own comics.^{[citation needed]}

Career[link]

In the early 1980s, both Jaime and Gilbert created flyer and cover art for local bands.^[1] He also did the cover artwork for the record Limbo by Throwing Muses. The alternative rock band Love and Rockets was named after the Hernández brothers' comic book.^[2]

The first wider recognition of Gilbert and his brothers' work occurred in 1982, after they had sent in a copy of their Love & Rockets comic, which up to that point they had been self publishing, to the Comics Journal, the foremost U.S. magazine of news and criticism pertaining to comic books and strips.^[3] This led to their work being published by the then just established Fantagraphics books. Between 1996 and 2001, the Love & Rockets series was temporarily suspended, while each brother, including Gilbert, pursued solo projects. During this time Gilbert created New Love, Luba, and Luba's Comics and Stories.^[1] After its resumption, Love & Rockets continued to be published by Fantagraphics on an annual basis. In 2009, Gilbert published The Troublemakers, his second solo graphic novel with the publisher, inspired by pulp novels and heist films.^[4] This has continued a trend he started with Chance in Hell and Speak of the Devil; all three books are faux adaptations of fictional B-movies.^[5]
