Merriam Press Korean War Series. A few weeks after North Korea invaded South Korea, MacArthur authorized the creation of a Provisional Raider Co. Of 800 volunteers, 115 made the cut, enduring weeks of grueling training. Raiders went ashore at Inchon with the Marines, and X Corps at Wonsan. They conducted long-range intelligence-gathering patrols in which they also inserted and removed Korean agents. During the Chosin Reservoir campaign they took and held open the mountain passes for the withdrawal of the Marines and the 7th Div. The Raiders were evacuated from North Korea on 14 December 1950, and assigned anti-guerrilla activities in South Korea. At Chang-to they were cut off and surrounded by two North Korean regiments. On 1 April 1951, all Ranger and Special Operations units were disbanded because the army high command believed they were not being utilized properly. This is their story, as told by a member of the unit. 32 photos, 7 documents.
