Royal Marines were involved in the Korean War. 41 (Independent) Commando was reformed in 1950, and was originally envisaged as a raiding force for use against North Korea. It performed this role in partnership with the United States Navy until after the landing of United States Army X Corps at Wonsan. It then joined the US's 1st Marine Division at Koto-Ri. As Task Force Drysdale with Lt. Col. D.B. Drysdale RM in command, 41 Commando, a USMC company, a US Army company and part of the divisional train fought their way from Koto-Ri to Hagaru after the Chinese had blocked the road to the North. It then took part in the famous withdrawal from Chosin Reservoir. After that, a small amount of raiding followed, before the Marines were withdrawn from the conflict in 1951. It received the Presidential Citation after the USMC got the regulations modified to allow foreign units to receive the award.
