Generally, a battle is a conceptual component in the hierarchy of combat in warfare between two or more armed forces, or combatants. In a battle, each combatant will seek to defeat the others, with defeat determined by the conditions of a military campaign. Battles generally are well defined in duration, area and force commitment.^[1]

Wars and military campaigns are guided by strategy, whereas battles take place on a level of planning and execution known as operational mobility.^[2] German strategist Carl von Clausewitz stated that "the employment of battles ... to achieve the object of war"^[3] was the essence of strategy.

Etymology[link]

The definition of a battle cannot be arrived at solely through the names of historical battles, many of which are misnomers. The word battle is a loanword in English from the Old French bataille, first attested in 1297, from Late Latin battualia, meaning "exercise of soldiers and gladiators in fighting and fencing", from Late Latin (taken from Germanic) battuere "beat", from which the English word battery is also derived via Middle English batri,^[4] and comes from the staged battles in the Colosseum in Rome that may have numbered 10,000 individuals.

Characteristics of battle[link]

The defining characteristic of the battle as a concept in the Theory of combat^[5] has been a dynamic one through the course of military history, changing with the changes in the organisation, employment and technology of military forces.

While the British military historian Sir John Keegan suggested an ideal definition of battle as "something which happens between two armies leading to the moral then physical disintegration of one or the other of them",^[6] the origins and outcomes of battles can rarely be summarized so neatly.

In general a battle during the 20th century was, and continues to be, defined by the combat between opposing forces representing major components of total forces committed to a military campaign, used to achieve specific military objectives, within a time-frame of less than a month.^[7] Where the duration of the battle is longer than a week, it is often for reasons of staff operational planning called an operation. Battles can be planned, encountered, or forced by one force on the other when the latter is unable to withdraw from combat.

A battle always has as its purpose the reaching of a mission goal by use of military force.^[8] A victory in the battle is achieved when one of the opposing sides forces the other to abandon its mission, or to surrender its forces, or routs the other, i.e., forces it to retreat or renders it militarily ineffective for further combat operations. However, a battle may end in a Pyrrhic victory, which ultimately favors the defeated party. If no resolution is reached in a battle, it can result in a stalemate. A conflict in which one side is unwilling to reach a decision by a direct battle using conventional military forces often becomes an insurgency.

Until the 19th century the majority of battles were of short duration, many lasting a part of a day. (The Battle of Nations (1813) and the Battle of Gettysburg (1863) were exceptional in lasting three days.) This was mainly due to the difficulty of supplying armies in the field, or conducting night operations. The means of prolonging a battle was typically by employment of siege warfare. Improvements in transportation and the sudden evolving of trench warfare, with its siege-like nature during World War I in the 20th century, lengthened the duration of battles to days and weeks.^[8] This created the requirement for unit rotation to prevent combat fatigue,^[9] with troops preferably not remaining in a combat area of operations for more than a month. Trench warfare had become largely obsolete in conflicts between advanced armies by the start of the Second World War.

The use of the term "battle" in military history has led to its misuse when referring to almost any scale of combat, notably by strategic forces involving hundreds of thousands of troops that may be engaged in either a single battle at one time (Battle of Leipzig) or multiple operations (Battle of Kursk). The space a battle occupies depends on the range of the weapons of the combatants. A "battle" in this broader sense may occupy a large piece of spacetime, as in the case of the Battle of Britain or the Battle of the Atlantic. Until the advent of artillery and aircraft, battles were fought with the two sides within sight, if not reach, of each other. The depth of the battlefield has also increased in modern warfare with inclusion of the supporting units in the rear areas; supply, artillery, medical personnel etc. often outnumber the front-line combat troops.

Battles are, on the whole, made up of a multitude of individual combats, skirmishes and small engagements within the context of which the combatants will usually only experience a small part of the events of the battle's entirety. To the infantryman, there may be little to distinguish between combat as part of a minor raid or as a major offensive, nor is it likely that he anticipates the future course of the battle; few of the British infantry who went over the top on the first day on the Somme, July 1, 1916, would have anticipated that they would be fighting the same battle in five months' time. Conversely, some of the Allied infantry who had just dealt a crushing defeat to the French at the Battle of Waterloo fully expected to have to fight again the next day.

Battlespace[link]

Battlespace is a unified strategy to integrate and combine armed forces for the military theatre of operations, including air, information, land, sea and space. It includes the environment, factors and conditions that must be understood to successfully apply combat power, protect the force, or complete the mission. This includes enemy and friendly armed forces; facilities; weather; terrain; and the electromagnetic spectrum within the operational areas and areas of interest.

Factors within battles[link]

Battles are decided by various factors. The number and quality of combatants and equipment, the skill of the commanders of each army, and the terrain advantages are among the most prominent factors. A unit may charge with high morale but less discipline and still emerge victorious. This tactic was effectively used by the early French Revolutionary Armies.

Weapons and armour can be a decisive factor. On many occasions armies have achieved victories largely owing to the employment of more advanced weapons than those of their opponents. An extreme example was in the Battle of Omdurman, in which a large army of Sudanese Mahdists armed in a traditional manner were destroyed by an Anglo-Egyptian force equipped with Maxim guns.

On some occasions, simple weapons employed in an unorthodox fashion have proven advantageous, as with the Swiss pikemen who gained many victories through their ability to transform a traditionally defensive weapon into an offensive one. Likewise, the Zulus in the early 19th century were victorious in battles against their rivals in part because they adopted a new kind of spear, the iklwa. Even so, forces with inferior weapons have still emerged victorious at times, for example in the Wars of Scottish Independence and in the First Italo–Ethiopian War. Discipline within the troops is often of greater importance; at the Battle of Alesia, the Romans were greatly outnumbered but won because of superior training.

Battles can also be determined by terrain. Capturing high ground, for example, has been the central strategy in innumerable battles. An army that holds the high ground forces the enemy to climb, and thus wear themselves down. Areas of dense vegetation, such as jungles and forest, act as force-multipliers, of benefit to inferior armies. Arguably, terrain is of less importance in modern warfare, due to the advent of aircraft, though terrain is still vital for camouflage, especially for guerrilla warfare.

Generals and commanders also play a decisive role during combat. Hannibal, Julius Caesar and Napoleon Bonaparte were all skilled generals and, consequently, their armies were extremely successful. An army that can trust the commands of their leaders with conviction in its success invariably has a higher morale than an army that doubts its every move. The British in the naval Battle of Trafalgar, for example, owed its success to the reputation of celebrated admiral Lord Nelson.

Types of battle[link]

The Battle of Poltava between Russia and Sweden, by Denis Martens the Younger

Battles can be fought on land, sea and in the modern age, in the air. Naval battles have occurred since before the 5th century BC. Air battles have been far less common, due to their late conception, the most prominent being the Battle of Britain in 1940. However since the Second World War land or sea battles have come to rely on air support. Indeed, during the Battle of Midway, five aircraft carriers were sunk without either fleet coming into direct contact.

There are numerous types of battles:

• A battle of encounter (or encounter battle) is a meeting engagement where the opposing sides collide in the field without either having prepared their attack or defence.

• A battle of attrition aims to inflict losses on an enemy that are less sustainable compared to one's own losses. These need not be greater numerical losses - if one side is much more numerous than the other than pursuing a strategy based on attrition can work even if casualties on both sides are about equal. Many battles of the Western Front in the First World War were intentionally (Verdun) or unintentionally (Somme) attrition battles.

• A battle of breakthrough aims to pierce the enemy's defences, thereby exposing the vulnerable flanks which can be turned.

• A battle of encirclement—the Kesselschlacht of the German Blitzkrieg—surrounds the enemy in a pocket.

• A battle of envelopment involves an attack on one or both flanks; the classic example being the double-envelopment of the Battle of Cannae.

• A battle of annihilation is one in which the defeated party is destroyed in the field, such as the French fleet at the Battle of the Nile.

Battles frequently do not fit one particular type perfectly, and are usually hybrids of different types listed above.

A decisive battle is one of particular importance; often by bringing hostilities to an end, such as the Battle of Hastings or the Battle of Hattin, or as a turning point in the fortunes of the belligerents, such as the Battle of Stalingrad. A decisive battle can have political as well as military impact, changing the balance of power or boundaries between countries. The concept of the decisive battle became popular with the publication in 1851 of Edward Creasy's The Fifteen Decisive Battles of the World. British military historians J.F.C. Fuller (The Decisive Battles of the Western World) and B.H. Liddell Hart (Decisive Wars of History), among many others, have written books in the style of Creasy's work.

The differences among land battles throughout history[link]

There is an obvious difference in the way battles have been fought throughout time. Early battles were probably fought between rival hunting bands as disorganized mobs. However, during the Battle of Megiddo, the first reliably documented battle in the fifteenth century BC, actual discipline was instilled in both armies. However, during the many wars of the Roman Empire, barbarians continued using mob tactics.

As the Age of Enlightenment dawned, armies began to fight in highly disciplined lines. Each would follow the orders from their officers and fight as a single unit instead of individuals. Each army was successively divided into regiments, battalions, companies, and platoons. These armies would march, line up, and fire in divisions.

Native Americans, on the other hand, did not fight in lines, utilizing instead guerrilla tactics. American colonists and European forces continued using disciplined lines, continuing into the American Civil War.

A new style, during World War I, known as trench warfare, developed nearly half a century later. This also led to radio for communication between battalions. Chemical warfare also emerged with the use of poisonous gas during World War I.

By World War II, the use of the smaller divisions, platoons and companies, became much more important as precise operations became vital. Instead of the locked trench warfare of World War I, during World War II, a dynamic network of battles developed where small groups encountered other platoons. As a result, elite squads became much more recognized and distinguishable.

Maneuver warfare also developed with an astonishing pace with the advent of the tank, replacing the archaic cannons of the Enlightenment Age. Artillery has since gradually replaced the use of frontal troops. Modern battles now continue to resemble that of World War II, though prominent innovations have been added. Indirect combat through the use of aircraft and missiles now comprise of a large portion of wars in place of battles, where battles are now mostly reserved for capturing cities^{[citation needed]}.

The evolution of naval warfare[link]

The Battle of Scheveningen of 1653: episode from the First Anglo-Dutch War.

One significant difference of modern naval battles as opposed to earlier forms of combat is the use of marines, which introduced amphibious warfare. Today, a marine is actually an infantry regiment that sometimes fights solely on land and is no longer tied to the navy. A good example of an old naval battle is the Battle of Salamis.

Most ancient naval battles were fought by fast ships using the battering ram to sink opposing fleets or steer close enough for boarding in hand-to-hand combat. Troops were often actually used to storm enemy ships as used by Romans and pirates. This tactic was usually used by civilizations that could not beat the enemy with ranged weaponry.

Another invention in the late Middle Ages was the use of Greek fire by the Byzantines, which was used to set enemy fleets on fire. Empty demolition ships utilized the tactic to crash into opposing ships and set it afire with an explosion. After the invention of cannons, naval warfare became useful as support units for land warfare.

During the 19th century, the development of mines led to a new type of naval warfare. The ironclad, first used in the American Civil War, resistant to cannons, soon made the wooden ship obsolete. The invention of military submarines, during World War I, brought naval warfare to both above and below the surface. With the development of military aircraft during World War II, battles were fought in the sky as well as below the ocean. Aircraft carriers have since become the central unit in naval warfare, acting as a mobile base for lethal aircraft.

Aerial battles throughout history[link]

Although the use of aircraft has for the most part always been used as a supplement to land or naval engagements, since their first major military use in World War I aircraft have increasingly taken on larger roles in warfare. During World War I, the primary use was for reconnaissance, and small-scale bombardment.

Aircraft began becoming much more prominent in the Spanish Civil War and especially World War II. Aircraft design began specializing, primarily into two types: bombers, which carried explosive payloads to bomb land targets or ships; and fighter-interceptors, which were used to either intercept incoming aircraft or to escort and protect bombers (engagements between fighter aircraft were known as dog fights). Some of the more notable aerial battles in this period include the Battle of Britain and the Battle of Midway.

Another important use of aircraft came with the development of the helicopter, which first became heavily used during the Vietnam War, and still continues to be widely used today to transport and augment ground forces.

Today, direct engagements between aircraft are rare - the most modern fighter-interceptors carry much more extensive bombing payloads, and are used to bomb precision land targets, rather than to fight other aircraft. Anti-aircraft batteries are used much more extensively to defend against incoming aircraft than interceptors. Despite this, aircraft today are much more extensively used as the primary tools for both army and navy, as evidenced by the prominent use of helicopters to transport and support troops, the use of aerial bombardment as the "first strike" in many engagements, and the replacement of the battleship with the aircraft carrier as the center of most modern navies.

Battle naming[link]

Battle of Gibraltar of 1607 by Hendrick Cornelisz Vroom.

Battles are usually named after some feature of the battlefield geography, such as the name of a town, forest or river, commonly prefixed "Battle of...". Occasionally battles are named after the date on which they took place, such as The Glorious First of June.

In the Middle Ages it was considered important to settle on a suitable name for a battle which could be used by the chroniclers. For example, after Henry V of England defeated a French army on October 25, 1415, he met with the senior French herald and they agreed to name the battle after the nearby castle and so it was called the Battle of Agincourt.

In other cases, the sides adopted different names for the same battle, such as the Battle of Gallipoli which is known in Turkey as the Battle of Çanakkale. During the American Civil War, the Union tended to name the battles after the nearest watercourse, such as the Battle of Wilsons Creek and the Battle of Stones River, whereas the Confederates favoured the nearby towns, as in the Battles of Chancellorsville and Murfreesboro. Occasionally both names for the same battle entered the popular culture, such as the battle of Antietam, which is also referred to as the battle of Sharpsburg.

Sometimes in desert warfare, there is no nearby town name to use; map coordinates gave the name to the Battle of 73 Easting in the First Gulf War.

Some place names have become synonymous with the battles that took place there, such as the Passchendaele, Pearl Harbor, the Alamo, Thermopylae, or Waterloo. Military operations, many of which result in battle, are given codenames, which are not necessarily meaningful or indicative of the type or the location of the battle. Operation Market Garden and Operation Rolling Thunder are examples of battles known by their military codenames.

When a battleground is the site of more than one battle in the same conflict, the instances are distinguished by ordinal number, such as the First and Second Battles of Bull Run. An extreme case are the twelve Battles of the Isonzo—First to Twelfth—between Italy and Austria-Hungary during the First World War.

Some battles are named for the convenience of military historians so that periods of combat can be neatly distinguished from one another. Following the First World War, the British Battles Nomenclature Committee was formed to decide on standard names for all battles and subsidiary actions. To the soldiers who did the fighting, the distinction was usually academic; a soldier fighting at Beaumont Hamel on November 13, 1916 was probably unaware he was taking part in what the committee would call the "Battle of the Ancre".

Many combats are too small to merit a name. Terms such as "action", "skirmish", "firefight", "raid" or "offensive patrol" are used to describe small-scale battle-like encounters. These combats often take place within the time and space of a battle and while they may have an objective, they are not necessarily "decisive". Sometimes the soldiers are unable to immediately gauge the significance of the combat; in the aftermath of the Battle of Waterloo, some British officers were in doubt as to whether the day's events merited the title of "battle" or would be passed off as merely an "action".^{[citation needed]}

The effects of a battle[link]

Battles affect the individuals who take part, as well as the political actors. Personal effects of battle range from mild psychological issues to permanent and crippling injuries. Some battle-survivors have nightmares about the conditions they encountered, or abnormal reactions to certain sights or sounds. Some suffer flashbacks. Physical effects of battle can include scars, amputations, lesions, loss of bodily functions, blindness, paralysis — and death.

Battles also affect politics. A decisive battle can cause the losing side to surrender, while a Pyrrhic Victory such as the Battle of Asculum can cause the winning side to reconsider its long-term goals. Battles in civil wars have often decided the fate of monarchs or political factions. Famous examples include the War of the Roses, as well as the Jacobite Uprisings. Battles also affect the commitment of one side or the other to the continuance of a war, for example the Battle of Incheon and the Battle of Hue during the Tet Offensive.

Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.

As president, Obama signed economic stimulus legislation in the form of the American Recovery and Reinvestment Act of 2009 and the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010. Other domestic policy initiatives include the Patient Protection and Affordable Care Act, the Dodd–Frank Wall Street Reform and Consumer Protection Act, the Don't Ask, Don't Tell Repeal Act of 2010, and the Budget Control Act of 2011. In May 2012, he became the first sitting U.S. president to openly support legalizing same-sex marriage. In foreign policy, he ended the war in Iraq, increased troop levels in Afghanistan, signed the New START arms control treaty with Russia, ordered U.S. involvement in the 2011 Libya military intervention, and ordered the military operation that resulted in the death of Osama bin Laden.

Early life and career[link]

Obama was born on August 4, 1961, at Kapiʻolani Maternity & Gynecological Hospital (now Kapiʻolani Medical Center for Women and Children) in Honolulu, Hawaii,^[2][4][5] and is the first President to have been born in Hawaii.^[6] His mother, Stanley Ann Dunham, was born in Wichita, Kansas, and was of mostly English ancestry,^[7] along with Scottish, Irish, German, and Swiss.^{[8][9][10][11][12]} His father, Barack Obama, Sr., was a Luo from Nyang’oma Kogelo, Nyanza Province, Kenya. Obama's parents met in 1960 in a Russian class at the University of Hawaiʻi at Mānoa, where his father was a foreign student on scholarship.^[13][14] The couple married on February 2, 1961,^[15] separated when Obama Sr. went to Harvard University on scholarship, and divorced in 1964.^[13] Obama Sr. remarried and returned to Kenya, visiting Barack in Hawaii only once, in 1971. He died in an automobile accident in 1982.^[16]

After her divorce, Dunham married Indonesian Lolo Soetoro, who was attending college in Hawaii. When Suharto, a military leader in Soetoro's home country, came to power in 1967, all Indonesian students studying abroad were recalled, and the family moved to the Menteng neighborhood of Jakarta.^[4][17] From ages six to ten, Obama attended local schools in Jakarta, including Besuki Public School and St. Francis of Assisi School.^[18]

In 1971, Obama returned to Honolulu to live with his maternal grandparents, Madelyn and Stanley Armour Dunham, and with the aid of a scholarship attended Punahou School, a private college preparatory school, from fifth grade until his graduation from high school in 1979.^[19] Obama's mother returned to Hawaii in 1972, remaining there until 1977 when she went back to Indonesia to work as an anthropological field worker. She finally returned to Hawaii in 1994 and lived there for one year before dying of ovarian cancer.^[15][20]

Of his early childhood, Obama recalled, "That my father looked nothing like the people around me—that he was black as pitch, my mother white as milk—barely registered in my mind."^[14] He described his struggles as a young adult to reconcile social perceptions of his multiracial heritage.^[21] Reflecting later on his years in Honolulu, Obama wrote: "The opportunity that Hawaii offered—to experience a variety of cultures in a climate of mutual respect—became an integral part of my world view, and a basis for the values that I hold most dear."^[22] Obama has also written and talked about using alcohol, marijuana, and cocaine during his teenage years to "push questions of who I was out of my mind."^[23] At the 2008 Civil Forum on the Presidency, Obama described his high-school drug use as a great moral failure.^[24]

Following high school, Obama moved to Los Angeles in 1979 to attend Occidental College. In February 1981, he made his first public speech, calling for Occidental to divest from South Africa in response to its policy of apartheid.^[25] In mid-1981, Obama traveled to Indonesia to visit his mother and sister Maya, and visited the families of college friends in Pakistan and India for three weeks.^[25] Later in 1981, he transferred to Columbia University in New York City, where he majored in political science with a specialty in international relations^[26] and graduated with a Bachelor of Arts in 1983. He worked for a year at the Business International Corporation,^[27] then at the New York Public Interest Research Group.^[28][29]

Chicago community organizer and Harvard Law School[link]

Two years after graduating, Obama was hired in Chicago as director of the Developing Communities Project (DCP), a church-based community organization originally comprising eight Catholic parishes in Roseland, West Pullman, and Riverdale on Chicago's South Side. He worked there as a community organizer from June 1985 to May 1988.^[29][30] He helped set up a job training program, a college preparatory tutoring program, and a tenants' rights organization in Altgeld Gardens.^[31] Obama also worked as a consultant and instructor for the Gamaliel Foundation, a community organizing institute.^[32] In mid-1988, he traveled for the first time in Europe for three weeks and then for five weeks in Kenya, where he met many of his paternal relatives for the first time.^[33] He returned to Kenya in August 2006 for a visit to his father's birthplace, a village near Kisumu in rural western Kenya.^[34]

In late 1988, Obama entered Harvard Law School. He was selected as an editor of the Harvard Law Review at the end of his first year,^[35] and president of the journal in his second year.^[31][36] During his summers, he returned to Chicago, where he worked as an associate at the law firms of Sidley Austin in 1989 and Hopkins & Sutter in 1990.^[37] After graduating with a J.D. magna cum laude^[38] from Harvard in 1991, he returned to Chicago.^[35] Obama's election as the first black president of the Harvard Law Review gained national media attention^[31][36] and led to a publishing contract and advance for a book about race relations,^[39] which evolved into a personal memoir. The manuscript was published in mid-1995 as Dreams from My Father.^[39]

University of Chicago Law School and civil rights attorney[link]

In 1991, Obama accepted a two-year position as Visiting Law and Government Fellow at the University of Chicago Law School to work on his first book.^[39][40] He then taught at the University of Chicago Law School for twelve years—as a Lecturer from 1992 to 1996, and as a Senior Lecturer from 1996 to 2004—teaching constitutional law.^[41]

From April to October 1992, Obama directed Illinois's Project Vote, a voter registration campaign with ten staffers and seven hundred volunteer registrars; it achieved its goal of registering 150,000 of 400,000 unregistered African Americans in the state, leading Crain's Chicago Business to name Obama to its 1993 list of "40 under Forty" powers to be.^[42] In 1993, he joined Davis, Miner, Barnhill & Galland, a 13-attorney law firm specializing in civil rights litigation and neighborhood economic development, where he was an associate for three years from 1993 to 1996, then of counsel from 1996 to 2004. His law license became inactive in 2002.^[43]

From 1994 to 2002, Obama served on the boards of directors of the Woods Fund of Chicago, which in 1985 had been the first foundation to fund the Developing Communities Project; and of the Joyce Foundation.^[29] He served on the board of directors of the Chicago Annenberg Challenge from 1995 to 2002, as founding president and chairman of the board of directors from 1995 to 1999.^[29]

Legislative career: 1997–2008[link]

State Senator: 1997–2004[link]
