Vietnam

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 the United States slowly began to withdraw troops. In January 1973, a cease-fire was arranged. The last U.S. ground troops left Vietnam two months later. Despite the treaty fighting between North and South Vietnam resumed soon afterward, but U.S. troops did not return. The war finally ended on April 30, 1975 when South Vietnam surrendered to North Vietnam.
