The term "Indochina" originally referred to French Indochina, which included the current states of Vietnam, Laos and Cambodia. In use, it applies largely to a geographic region, rather than to a political area. The wars included: - The Vietnam War, also known as the Second Indochina War, and known in Vietnam as Resistance War Against America or simply the American War, was a war that occurred in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and the government of South Vietnam. The North Vietnamese army was supported by the Soviet Union, China and other communist allies and the South Vietnamese army was supported by the United States, South Korea, Australia, Thailand and other anti-communist allies and the war is therefore considered a Cold War-era proxy war. - Operation Masher (24 January6 March 1966) was in early 1966 the largest search and destroy mission that had been carried out in the Vietnam War up until that time. It was a combined mission of the United States Army, Army of the Republic of Vietnam (ARVN), and Republic of Korea Army (ROKA) in Binh Dinh province on the central coast of South Vietnam. The 3rd Division of the communist North Vietnamese Army, made up of two regiments of North Vietnamese regulars and one regiment of main force Viet Cong guerrillas, controlled much of the land and many of people of Binh Dinh province which had a total population of about 800,000. A CIA report in 1965 said that Binh Dinh was "just about lost" to the communists. - South Vietnam, officially the Republic of Vietnam was a state governing the southern half of Vietnam from 1955 to 1975. It received international recognition in 1949 as the "State of Vietnam" (194955), and later as the "Republic of Vietnam" (195575). Its capital was Saigon. The term "South Vietnam" became common usage in 1954, when the Geneva Conference provisionally partitioned Vietnam into communist and non-communist parts. - The Pleiku Campaign took place from 23 October to 26 November. II Corps Command named it Pleime Campaign, with a slightly different starting date of 20 October instead of 23 consisted of three operations: - The Cold War was a state of political and military tension after World War II between powers in the Eastern Bloc (the Soviet Union and its satellite states) and powers in the Western Bloc (the United States, its NATO allies and others). Historians do not fully agree on the dates, but a common timeframe is the period (the second half of the 20th century) between 1947, the year the Truman Doctrine (a U.S. policy pledging to aid nations threatened by Soviet expansionism) was announced, and 1991, the year the Soviet Union collapsed. - The Battle of Ia Drang comprises two main engagements conducted by the 1st Battalion, 7th Cavalry Regiment that took place on November 1415, 1965 at LZ X-Ray ("eastern foot of the Chu Pong massif") and by the 2nd Battalion, 7th Cavalry Regiment on November 17 at LZ Albany further north in the Ia Drang Valley. It was the first major battle between the United States Army and the North Vietnamese Army-NVA (People's Army of Vietnam-PAVN) during the Vietnam War as part of the U.S. airmobile offensive code-named Operation Silver Bayonet I (October 23 November 18, 1965). The battle was part of the second phase of a search-and-destroy operation code-named "Operation Long Reach" that took place from October 23 to November 26 during the Pleiku Campaign. - The Battle of Bng Sn was the second major battle for the US 1st Cavalry Division, an airmobile unit of divisional strength, during the Vietnam War. The battle was part of Operation Masher, also known as Operation Whitewing. A month earlier in 1965, in the Battle of the Ia Drang, the 1st Cavalry used all the division infantry, but one brigade at a time. One of the realizations that affected Bong Son was that with adequate helicopter lift, the traditional need to keep a strong reserve was less requiredthe least involved unit usually could break away and go where it was needed. - The Fall of Saigon, or the Liberation of Saigon, depending on context, 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 Vit Cng) 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. - The United States Army (USA) is the largest branch of the United States Armed Forces and performs land-based military operations. It is one of the seven uniformed services of the United States and is designated as the Army of the United States in the United States Constitution, Article 2, Section 2, Clause 1 and United States Code, Title 10, Subtitle B, Chapter 301, Section 3001. As the largest and senior branch of the U.S. military, the modern U.S. Army has its roots in the Continental Army, which was formed (14 June 1775) to fight the American Revolutionary War (17751783)before the U.S. was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784, to replace the disbanded Continental Army.
