The UN force retreats in Korea

MacArthur underestimated the power of the Chinese. Late in 1950, 200,000 Chinese troops joined the North Koreans and attacked. They had soldiers who were strongly committed to Communism and had been taught to hate the Americans. The United Nations forces were pushed back into South Korea. Conditions were some of the worst the American forces had known. The Chinese forces were more familiar with fighting in these conditions.
