In short: In November 1970, U.S. forces executed a meticulously planned, high-stakes rescue mission at the Son Tay prison camp, located 23 miles west of Hanoi. Despite flawless execution and intense training, the raiders discovered the facility was empty. The prisoners had been moved shortly before the assault, sparking a major intelligence overhaul.

Operation Ivory Coast was the first joint military mission in U.S. history directed by the Chairman of the Joint Chiefs of Staff. Planning began in May 1970 after intelligence analysis of aerial photography suggested 55 American prisoners were held at a compound near Son Tay. A 15-member study group later concluded the camp actually held 61 prisoners. To prepare, the task force built a replica of the prison at Eglin Air Force Base in Florida, where they conducted 170 practice sessions, including full-scale night rehearsals.

The mission launched on 21 November 1970, involving 116 aircraft and 219 personnel. To mask the raid, U.S. Navy forces conducted the largest carrier night operation of the Vietnam War, saturating North Vietnamese air defenses with flares and chaff. Despite this, the ground assault faced immediate complications. The lead helicopter mistakenly landed at a nearby barracks, which was identified as a secondary school during planning. This triggered an eight-minute firefight where the support group estimated they killed 100 to 200 hostile soldiers.

The assault team, led by Captain Richard J. Meadows, successfully breached the actual prison compound at 02:19. After a systematic, cell-by-cell search, they confirmed the absence of prisoners and transmitted the code phrase 'Negative Items.' The raiders withdrew with only two casualties and two aircraft losses. While the mission failed to recover any POWs, the embarrassment caused by the intelligence failure regarding the prisoners' relocation prompted a significant reorganization of the United States intelligence community in 1971.

The operation remains a case study in complex military planning and the limitations of intelligence. The raiders were heavily equipped with specialized tools, including chainsaws and bolt cutters, and utilized innovative flight profiles to maintain secrecy. Although the mission did not achieve its primary objective, the execution demonstrated the capability of U.S. Special Operations Forces to conduct deep-penetration raids under extreme conditions, even as the failure to track the prisoners' movements highlighted critical gaps in strategic reconnaissance.
