Hanoi Hilton Rescue Mission Overview

In May 1972, the USS Greyback embarked on a mission to rescue American prisoners from a North Vietnamese prison. The mission, led by Navy Captain John Chamberlain and Seal Team 1's Alpha platoon, awaited a signal from President Nixon, which was delivered by SR71 aircraft. However, the mission faced challenges as American officers in the prison were divided on the escape plan. Operation Thunderhead monitored the situation, but no prisoners appeared. The Vietnam War concluded in January 1973 after Nixon's final bombing campaign, leading to the return of prisoners who were grateful for clandestine assistance.
