April 30 is best known for 1975, when North Vietnamese tanks rolled into Saigon and South Vietnam surrendered, ending the Vietnam War. The same date saw George Washington sworn in as the first U.S. president in 1789 and Tim Berners-Lee put the World Wide Web’s software in the public domain in 1993.
The big story: Saigon falls (1975)
The end came fast. South Vietnam’s president, Nguyen Van Thieu, resigned, and on April 25, 1975, he fled Saigon. By April 27, North Vietnamese forces had the capital surrounded. His successor, Tran Van Huong, held the job for a single day before handing it to General Duong Van Minh. As Americans and their Vietnamese allies scrambled to get out, U.S. helicopters carried out what has been called the largest helicopter evacuation of its kind. At dawn on April 30, the final attack began. It met little resistance. North Vietnamese tanks smashed through the gates of the Presidential Palace, and Minh surrendered to Colonel Bui Tin, who told him he had nothing to fear. The surrender ended the Vietnam War, a long conflict that had divided Americans at home. Saigon is now known as Ho Chi Minh City.
