(1945-1954). The war developed as a sequel to the struggle (1946-1954) between the French, who were the colonial rulers of Indo-China before World War II, and the Communist-led Vietminh, or League for the Independence of Vietnam, founded and headed by the revolutionary leader Ho Chi Minh. Having emerged as the strongest of the nationalist groups that fought the Japanese occupation of French Indo-China during World War II, the league was determined to resist the re-establishment of French colonial rule and to implement political and social changes.
Following the surrender of Japan to the Allies in August 1945, Vietminh guerrillas seized the capital city of Hanoi and forced the abdication of Emperor Bao Dai. On September 2 they declared Vietnam to be independent and announced the creation of the Democratic Republic of Vietnam, commonly called North Vietnam, with Ho Chi Minh as president. France officially recognized the new state, but the subsequent inability of the Vietminh and France to reach satisfactory political and economic agreements led to armed conflict beginning in December 1946. With French backing Bao Dai set up the state of Vietnam, commonly called South Vietnam, on July 1, 1949, and established a new capital at Saigon (now Ho Chi Minh City). The following year, the United States officially recognized the Saigon government, and to assist it, US President Harry S. Truman dispatched a military assistance advisory group to train South Vietnam in the use of US weapons. In the meantime, the two main adversaries in Vietnam—France and the Vietminh—were steadily building up their forces. The decisive battle of the war developed in the spring of 1954 as the Vietminh attacked the French fortress of Điên Biên Phu (also known as Điên Biên) in northern Vietnam. On May 8, 1954, after a 55-day siege, the French surrendered. On the same day, both North and South Vietnamese delegates met with those of France, Great Britain, the Soviet Union, the United States, Communist China, and the two neighbouring states, Laos and Cambodia, in Geneva, to discuss the future of all of Indo-China. Under accords drawn up at the conference, France and North Vietnam agreed to a truce. It was further agreed to partition the country temporarily along the 17th parallel, with the north going to the Communists and the south placed under the control of the Saigon government. The agreement stipulated that elections for reunification of the country would be held in 1956. Neither the United States nor the Saigon government agreed to the Geneva accords, but the United States announced it would do nothing to undermine the agreement. Once the French had withdrawn from Vietnam, the United States moved to bolster the Saigon government militarily and, as asserted by some observers, engaged in covert activities against the Hanoi government. On October 24, 1954, President Dwight D. Eisenhower offered South Vietnam direct economic aid, and the following February, US military advisers were dispatched to train South Vietnamese forces. American support for the Saigon government continued even after Bao Dai was deposed, in a referendum on October 23, 1955, and South Vietnam was made a republic, with Ngo Dinh Diem as president. One of Diem's first acts was to announce that his government would refuse to hold reunification elections, on the grounds that the people of North Vietnam would not be free to express their will and because of the probability of falsified votes (although Diem and other South Vietnamese officials were also accused of fraudulent election practices).
THE NEW WAR BEGINS
The position taken by Diem won the backing of the United States. The Communist government in Hanoi, however, indicated its determination to reunify the nation under their rule. The truce arranged at Geneva began to crumble and by January 1957, the International Control Commission set up to implement the Geneva accords was reporting armistice violations by both North and South Vietnam. Throughout the rest of the year, Communist sympathizers who had gone north after partition began returning south in increasing numbers. Called Vietcong, they began launching attacks on US military installations that had been established, and in 1959 began their guerrilla attacks on the Diem government. The attacks were intensified in 1960, the year in which North Vietnam proclaimed its intention “to liberate South Vietnam from the ruling yoke of the US imperialists and their henchmen”. The statement served to reinforce the belief that the Vietcong were being directed by Hanoi. On November 10, the Saigon government charged that regular North Vietnamese troops were taking a direct part in Vietcong attacks in South Vietnam. To show that the guerrilla movement was independent, however, the Vietcong set up their own political arm, known as the National Liberation Front (NLF), with its headquarters in Hanoi.
