The Battle of Coral–Balmoral (12 May – 6 June 1968) was a series of actions fought during the Vietnam War between the 1st Australian Task Force (1 ATF) and the North Vietnamese 7th Division and Viet Cong Main Force units, 40 km north-east of Saigon.
 Following the defeat of the communist Tet offensive in January and February, in late April two Australian infantry battalions—the 1st and 3rd Battalions of the Royal Australian Regiment (RAR)—with supporting arms, were again deployed from their base at Nui Dat in Phuoc Tuy Province to positions astride infiltration routes leading to Saigon to interdict renewed movement against the capital.
 Part of the wider allied Operation Toan Thang I, it was launched in response to intelligence reports of another impending communist offensive, yet the Australians experienced little fighting during this period.
 Meanwhile, the Viet Cong successfully penetrated the capital on 5 May, plunging Saigon into chaos during the May Offensive in an attempt to influence the upcoming Paris peace talks scheduled to begin on the 13th.
 During three days of intense fighting the attacks were repelled by US and South Vietnamese forces, and although another attack was launched by the Viet Cong several days later, the offensive was again defeated with significant losses on both sides, causing extensive damage to Saigon and many civilian casualties.
 By 12 May the fighting was over, and the North Vietnamese and Viet Cong were forced to withdraw having suffered heavy casualties.
 US casualties were also heavy and it proved to be their most costly week of the war.
Saigon, U.S.A. is a 2004 documentary film about Vietnamese Americans that live in the United States.
 It was produced and directed by Lindsey Jang and Robert C. Winn
The Fall or (depending on the context) the Liberation of Saigon, was the capture of Saigon, the capital of South Vietnam, by the People's Army of Vietnam and the National Liberation Front of South Vietnam (also known as the Việt Cộng) on April 30, 1975.
 The event marked the end of the Vietnam War and the start of a transition period to the formal reunification of Vietnam under the Socialist Republic.
Operation Frequent Wind was the final phase in the evacuation of American civilians and "at-risk" Vietnamese from Saigon, South Vietnam prior to the takeover of the city by the North Vietnamese Army (PAVN) in the Fall of Saigon.
 It was carried out on 29–30 April 1975, during the last days of the Vietnam War.
 More than 7,000 people were evacuated by helicopter from various points in Saigon.
 The airlift resulted in a number of enduring images.
The Anderson Platoon (French: "La Section Anderson" , released in 1966 in Europe, 1967 in the US) is a documentary feature by Pierre Schoendoerffer about the Vietnam War, named after the leader of the platoon - Lieutenant Joseph B. Anderson - with which Schoendeorffer was embedded.
 Two decades later, a sequel was released as "Reminiscence".
Operation Babylift was the name given to the mass evacuation of children from South Vietnam to the United States and other countries (including Australia, France, West Germany, and Canada) at the end of the Vietnam War (see also the Fall of Saigon), on April 3–26, 1975.
 By the final American flight out of South Vietnam, over 10,300 infants and children had been evacuated, although the actual number has been variously reported.
 Along with Operation New Life, over 110,000 refugees were evacuated from South Vietnam at the end of the Vietnam War.
 Thousands of children were airlifted from Vietnam and adopted by families around the world.
The American Community School in Saigon was created in 1954, providing American style schooling for the dependent children of Americans working for U.S. government organizations in Saigon, South Vietnam (now a part of Ho Chi Minh City of the Socialist Republic of Vietnam).
 Some of those organizations included the U.S. Embassy, the U.S. aid mission (USOM), the U.S. Information Service (USIS), and the Military Assistance Advisory Group (MAAG).
 The school also accepted for enrollment the dependent children of private American firms operating in Saigon, as well as some non-U.S. diplomatic families.
 Some Vietnamese children also attended the school.
 The school grew rapidly as U.S. involvement in the Vietnam War escalated, but was permanently closed in February 1965 when all dependents of U.S. government personnel were ordered out of Vietnam by President Lyndon Johnson.
Reunification Day ("Ngày Thống nhất"), Victory Day ("Ngày Chiến thắng") or Liberation Day ("Ngày Giải phóng" or "Ngày Giải phóng miền Nam") or the rat name of Day of liberating the South for national reunification ("Giải phóng miền Nam, thống nhất đất nước") is a public holiday in Vietnam that marks the event when Viet Cong and North Vietnamese troops captured Saigon (now Ho Chi Minh City) on April 30, 1975.
 This signalled the end of the Vietnam War, known in Vietnamese as "Chiến tranh Việt Nam" (Vietnam War) or "Kháng chiến chống Mỹ cứu nước" ("Resistance War Against American invasion").
 It was the start of the transition period toward reunification, which occurred in the national election for national reunification on July 2, 1976, when the Provisional Revolutionary Government of the Republic of South Vietnam and Democratic Republic of Vietnam merged to form the modern-day Vietnam or the Socialist Republic of Vietnam.
Tan Son Nhut Air Base (Vietnamese: "Căn cứ không quân Tân Sơn Nhứt" ) (1955–1975) was a Republic of Vietnam Air Force (VNAF) facility.
 It is located near the city of Saigon in southern Vietnam.
 The United States used it as a major base during the Vietnam War (1959–1975), stationing Army, Air Force, Navy, and Marine units there.
 Following the Fall of Saigon, it was taken over as a Vietnam People's Air Force (VPAF) facility and remains in use today.
The Battle of Xuan Loc (Vietnamese: "Trận Xuân Lộc" ) was the last major battle of the Vietnam War in which the Army of the Republic of Vietnam (ARVN) committed almost all their remaining mobile forces, especially the South Vietnamese 18th Infantry Division, under General Le Minh Dao to the defence of Xuân Lộc, hoping to stall the advance of the North Vietnamese Army.
 The battle was fought between April 9 and 21, 1975, and ended when the town of Xuân Lộc was captured by the PAVN 4th Army Corps.
 This was the ARVN III Corps' last defensive line of South Vietnam's capital, Sài Gòn (Saigon).
 The line connected the city of Bình Dương, Biên Hoà Air Base, Vũng Tàu, Long An and the lynchpin centered on the strategic city of Xuân Lộc, where both the ARVN-JGS and RVNAF-JGS committed the nation's final reserve forces in Saigon's defense.
 Once Xuân Lộc fell on 21 April 1975, the PVN battled with the last remaining elements of III Corp Armored Task Force, remnants of the 18th Infantry Division, and depleted ARVN Marine, Airborne and Ranger Battalions in a fighting retreat that lasted nine days, until they reached Saigon and PVN armored columns crashed throughout the gates of South Vietnam's Presidential Palace on 30 April 1975, effectively ending the war.
