1975 in the Vietnam War

1975 marked the end of the Vietnam War. After the South Vietnamese army folded under NVA pressure the Fall of Saigon was inevitable. The US started evacuating its citizens but to not alarm the South Vietnamese they left under a number of pretexts including Operation Babylift. On April 30, 1975 Saigon fell and the Vietnam War was over.
