After French Indochina falling, with the 1954 Geneva Conference on 21 July, the country gained independence from France but was divided into two parts: the Viet Minh took control of Northern parts of Vietnam, while the U.S. assumed financial and military support for South Vietnam. The Viet Cong or VC, a Southern Vietnamese area under the north, and the VC usually uses gurreilla warfare. The north Vietnamese forces fought in more conventional warfare with U.S. and the Republic parts of Vietnam. In 1958, Northern Vietnam invaded Laos, making the Ho Chi Minh Trail to help the Viet Cong. The north. U.S. got more involved.
Ever since the Gulf of Tonkin battle, Congress allowed President Lyndon B. Johnson to raise forces of troops in Vietnam, although not declaring a official war yet. He raised troops by a ton, up to 184,000. Thier strategy was to completely out-gun the forces with sheer fire power and air dominance. Bombing runs and troop increases were made, but it didn't have significant impact. The north launched a offensive but lost, It was still a win in some sort of way because it made the citizens of America start to dislike the war. Later, the VC was in charge of only a little bit of land.
In 1969, VC supply lines were destroyed by America in Laos and Cambodia. Norodom Sihanouk was the king of Cambodia then and caused the invasion of the nation by the Khmer Rouge. Then the U.S joined in, which was the Cambodian Civil War. In the same year, Richard Nixon became president, and started a policy called Vietnamization. Forces however withdrew because of opposers in America, and the army in Vietnam had little to no troops. In 1973, its said all forces have left, but then still fought for 2 years, before it finally ended on April 30, 1975, and the North and southern Vietnam reunited.
