This YouTube video here is self-explanatory about the Fall of Saigon. The aftermath of the Fall of Saigon is briefly touched in this video, but here is a little bit more information about the aftermath of Saigon.
As Saigon is coming to a loss in this one part of the Vietnam War, North Vietnam is coming in South Vietnam. With the American army able to rescue some of the southern Vietnamese citizens from the Northern Vietnamese army, the next decade wouldn't be so easy for the capital of the now-vanquished Southern regime. Saigon was now renamed after Ho Chi Minh to honor him and for the revolutionary leader he was and how he claimed independence in 1945.
