Cause

Operation Courageous sought to trap large PVA and KPA forces between the Han and Imjin Rivers north of Seoul. US I Corps was to advance rapidly toward the Imjin River, while a separate airborne insertion would cut off enemy retreat. The 187th RCT was selected to execute this blocking role approximately 30 kilometres north of the existing front line.

Event

On 23 March 1951, over 120 C-119 and C-46 aircraft dropped 3,437 paratroopers of the 187th RCT and 12 members of the Indian Army's 60th Parachute Field Ambulance near Munsan-ni. Upon landing, the force linked up with armored and infantry elements of Task Force Growdon and advanced toward their objectives, marking the first successful aerial delivery of 105mm howitzers and heavy equipment.

Consequence

The PVA/KPA had already withdrawn before the airborne force could encircle them, resulting in only light resistance—mainly minefields. The operation yielded 136 enemy killed and 149 captured, with 19 American fatalities. It remained the last full-scale U.S. combat parachute jump until Operation Junction City in Vietnam in 1967.
