When war broke out between North Korea and South Korea in 1950, Canada sent 26,971 military personnel to the Korean peninsula as part of a United Nations force, the third largest contingent behind the United States and the United Kingdom. Additionally, Canadians saw action in both naval and air forces with eight destroyers, 3,621 naval officers and men, twenty-two fighter pilots and several technical officers; whom were attached to the U.S. Fifth Air Force. Canada continued peacekeeping operations in Korea with the introduction of the Armistice Agreement. Due to the nature of the Korean War as the "Forgotten War", public awareness has been raised with the dedication of a national monument in 1997 - the Wall of Remembrance in Brampton, Ontario. 516 Canadians died in the war and 378 Canadians lie buried in the United Nations Memorial Cemetery in Busan.
