Description: In late January of 1968, a watershed event, known as the Tet Offensive, occurred during the Vietnam War. North Vietnam and the communist Viet Cong launched coordinated attacks in Saigon and areas of South Vietnam against the forces of the South Vietnamese Army and the United States military forces and their allies. While the Viet Cong were unsuccessful in their campaign, the Tet Offensive is said to have played a key role in weakening U.S. public support for the war and undermining the confidence of Americans in their government. To help researchers gain a deeper understanding of this pivotal moment in the Vietnam War, this collection contains film, case studies and primary source materials from the National Archives and Records Adminstration's Records of the U.S. Forces in Southeast Asia.
