Korean War truce talks began July 10, 1951. Although the talks started slowly, on Nov. 27, 1951, the two sides agreed on the 38th Parallel as the line of demarcation and almost immediately military operations slowed down. When Gen. Mark Clark assumed command of U.N. forces in Korea, on May 12, 1952, he was confronted with a military deadlock on the front lines, stalled Armistice negotiations, and a violent prisoner of war situation on the island of Koje-do, off the southern coast of South Korea. Clark believed that the Communists only understood force and stepped up military pressure on the enemy to break the stalemate at Panmunjom.
