Battle of Chosin Reservoir
On November 27, 1950, the Korean War Battle of Chosin Reservoir began, a fighting withdrawal in the bitter cold.
By November 1950, the United Nations forces had driven the North Korean army back into its own territory. The Yalu River, the northern border of the peninsula was within reach and many believed the war would be over by Christmas. American and UN commanders didn’t realize Chinese forces were massing along the border and would soon change the course of the war.
