March 24, 1975 – It what would be the final chapter in the long history of the Vietnam war, the North Vietnamese Politburo orders the start of the Ho Chi Minh Campaign whose objective was to celebrate the Vietnamese leader’s birthday (September 2nd) in Saigon. As part of the 1973 Paris Peace Accord, then President Nixon had promised to come to the defense of the South Vietnamese if the North where to attack. After Nixon’s resignation on August 9, 1974, the North Vietnamese started a series of smaller campaigns in December 1974. With Nixon gone, the United States did nothing. With ever-increasing momentum, the North Vietnamese regulars and Viet Cong guerrillas moved south and east eventually leaving only the area around Saigon. On March 24th they moved in for the kill and would eventually take Saigon April 30, well ahead of their objective. On May 1st, the city of Saigon was renamed Ho Chi Minh City in honor of the father of the now united Socialist Republic of Vietnam.
