The release of U.S. POWs begins in Hanoi as part of the Paris peace settlement. The return of U.S. POWs began when North Vietnam released 142 of 591 U.S. prisoners at Hanoi’s Gia Lam Airport. Part of what was called Operation Homecoming, the first 20 POWs arrived to a hero’s welcome at Travis Air Force Base in California on February 14. Operation Homecoming was completed on March 29, 1973, when the last of 591 U.S. prisoners were released and returned to the United States.
