April 30 is a day of mixed emotions for Vietnamese people and veterans of the Vietnam War. It is the day of the reunification of Vietnam but it is also the day the Americans and the South Vietnamese lost the war/their country, respectively. Sometimes it is called Black April because the lead-up to the end lasted throughout the month of April.
Last Days in Vietnam, an Academy Award-winning documentary by Rory Kennedy, depicts the events throughout that last stand of April 1975. The story is told from the point of views of various American naval and military men and South Vietnamese soldiers and civilians. Starting with a brief synopsis of the situation in January 1973, the documentary then fast-forwards to April 1975 and the surrender of Saigon to North Vietnamese troops.
