fall of 1950, 10, 587 men had volunteered to fight in Korea. Canada sent 26,791 Canadians to serve in the Korean War, with 7,000 more remaining to supervise the ceasefire until the end of 1955. Of these 1,558 became casualties, including 516 deaths, most due to combat. Canada's participation included several naval vessels and aircraft, in addition to the 25th Canadian Infantry Brigade which served as part of the 1st Commonwealth Division. In late 1950, Princess Patricia's Regiment left for South Korea and in February 1951 entered the line as part of an Anglo-Australian brigade. Princess Patricia's regiment was engaged in heavy fighting during the Battle of Kapyong on 22–25 April 1951 when a Chinese assault caused a South Korean division to collapse in the Kapyong valley; Princess Patricia's regiment was sent with British, Australian and New Zealand units in to hold the line. At one point during the night of April 22–23, 1951, Princess Patricia's had to call down artillery fire on their own positions to stop the advancing Chinese.

The 25th Brigade fitted in well with the British, Australian and New Zealand soldiers of the Commonwealth Division fighting for the Crown on the war-scarred hills of Korea. Canada's military was revitalized as a result of the Korean War. A planned changeover to US-designed weapons equipment had been planned for the 1950s, but the emergency in Korea forced the use of war stocks of Second World War–vintage British-designed weapons. On 5 February 1951, at a time when the Chinese were advancing in Korea, the Defence Minister, Brooke Claxton, announced in the House of Commons an emergency military budget of $5 billion which committed the government to raise an infantry division within the next three years and committed a brigade to Europe at once. At the time, it was believed that Stalin had ordered the North Korean invasion of South Korea in June 1950 as a part of a diversion to tie down Western forces in Korea as a prelude to a Soviet invasion of West Germany. Consequently, Canada followed the United States in increasing forces for the defence of
