The Battle of An Lộc was a major battle of the Vietnam War that lasted for 66 days and culminated in a decisive victory for South Vietnam. In many ways, the struggle for An Lộc in 1972 was an important battle of the war, as South Vietnamese forces halted the North Vietnamese advance towards Saigon.

An Lộc is the capital of Bình Phước Province located northwest of Military Region III. During North Vietnam's "Easter Offensive", officially known as the Nguyen Hue Offensive of 1972, An Lộc was at the centre of North Vietnamese strategy due to its location on QL-13 between Base Area 708 in Cambodia, and Saigon. To protect this important area the Republic of Vietnam had essentially one single division in Bình Phước Province, the ARVN 5th Division. During the battle the 5th ARVN division was outnumbered by a combined force of three North Vietnamese and Viet Cong divisions resulting in the most protracted conflict of the whole 1972 Easter Offensive.

On the same day that Loc Ninh—a small town 20 miles (32 km) north of An Loc on the border with Cambodia was assaulted the (NVA) PAVN 7th division launched an attack on Route 13 in an attempt to cut off An Loc from Saigon. To control route QL-13 was to control the road to Saigon, some 90 miles (140 km) to the south. This prevented resupply of ARVN forces in An Loc.

The Battle of Antietam ( /ænˈtiːtəm/) also known as the Battle of Sharpsburg, particularly in the South, fought on September 17, 1862, near Sharpsburg, Maryland, and Antietam Creek, as part of the Maryland Campaign, was the first major battle in the American Civil War to take place on Union soil. It was the bloodiest single-day battle in American history, with about 23,000 casualties on both sides.

After pursuing Confederate General Robert E. Lee into Maryland, Union Army Maj. Gen. George B. McClellan launched attacks against Lee's army, in defensive positions behind Antietam Creek. At dawn on September 17, Maj. Gen. Joseph Hooker's corps mounted a powerful assault on Lee's left flank. Attacks and counterattacks swept across Miller's cornfield and fighting swirled around the Dunker Church. Union assaults against the Sunken Road eventually pierced the Confederate center, but the Federal advantage was not followed up. In the afternoon, Union Maj. Gen. Ambrose Burnside's corps entered the action, capturing a stone bridge over Antietam Creek and advancing against the Confederate right. At a crucial moment, Confederate Maj. Gen. A.P. Hill's division arrived from Harpers Ferry and launched a surprise counterattack, driving back Burnside and ending the battle. Although outnumbered two-to-one, Lee committed his entire force, while McClellan sent in less than three-quarters of his army, enabling Lee to fight the Federals to a standstill. During the night, both armies consolidated their lines. In spite of crippling casualties, Lee continued to skirmish with McClellan throughout September 18, while removing his battered army south of the Potomac River.

An Lộc is a small town in Bình Phước Province in southern Vietnam, located approximately 90 km north of Saigon (Ho Chi Minh City) with a population of 15,000. The town became famous during the Vietnam War, as the location of a major battle in 1972.

In North Vietnam's Easter Offensive of 1972, the Communist Politburo/General Vo Nguyen Giap planned simultaneous attacks to capture as much territory as possible and to defeat the US-supported South Vietnamese Army of the Republic of Vietnam (ARVN). By then, the number of United States ground forces in South Vietnam had fallen to 65,000 from an all-time high of 543,000 in 1969; and the North Vietnamese correctly anticipated that the US was unwilling to commit ground troops again. An aerial armada consisting of United States Air Force (USAF) B-52 Stratofortresses, F-4 Phantom IIs, A-37 Dragonflies and US Navy planes from four aircraft carrier wings and some Vietnam Air Force (VNAF) fighters, however, were at hand to provide strong and at times crucial air-support.

The Battle of An (Chinese: 鞍之战; pinyin: Ān zhī Zhàn) was fought during the Spring and Autumn Period in 589 BC at Hua Hill in the area of the present-day city of Jinan, Shandong between the states of Qi and Jin. It ended in a victory for the state of Jin and eventually resulted in an alliance between the two states.

Two of the three surviving commentaries on the Spring and Autumn Annals, the Zuo Zhuan and the Guliang Zhuan describe the event that led to the battle as an insult that an emissary of Jin suffered at the court of Qi, but the two accounts differ on the nature of the insult. According to the Zuo Zhuan, the duke of Qi allowed women to watch the emissary's visit from behind a screen, women who then insulted the emissary with their laughter. The Guliang Zhuan claims that the duke of Qi insulted the emissaries of four visiting states by assigning each of them a server who shared their respective physical defects.
