When was the last day of the Vietnam War?

 Vietnam is a small country in Southeast Asia. In 1954, it was divided into communist-ruled North Vietnam, and non communist South Vietnam. North Vietnam wanted to end US support of South Vietnam, and to unite the north and south into a single nation. Over the next ten years, tensions in the area increased as the conflict between North and South Vietnam grew. When North   Vietnam attacked a US destroyer on August 2nd 1964, USA officially entered the Vietnam War.

The Vietnam War was the longest war in which the United States took part. The first U.S. troops entered Vietnam in March 1965. Until 1969, North Vietnam and the United States did most of the fighting. By 1969, the Vietnam War seemed endless, and many Americans opposed American involvement in the war. As a result, United States slowly began to withdraw troops. On 29th April 1975, the US began a massive helicopter evacuation, airlifting 1000 Americans and 6000 South Vietnamese from the capital city of Saigon. The official last day of the war was 30th April 1975, when South Vietnam surrendered to North Vietnam.
