The Royal Canadian Navy, with over a century of service under its belt, has always answered its call to duty. In particular, on July 30, 1950,[1],[5], the Royal Canadian Navy was ordered to deploy part of its fleet to Japan to assist its allies in an emerging conflict in Korea. The previous month, on June 24, 1950, heightened tensions on the Korean Peninsula boiled over and the small border town of Ongijin was heavily bombed as the first light of dawn broke the horizon.[1],[5] . Shortly after, North Korean troops began crossing the border, heavily supported by their armored divisions, signaling the start of the next Great Korean War.[1] On June 27, 1950, the RCN began preparing its Pacific Fleet for wartime status following the Security Council meeting at the United Nations that day.[1] Canada's three main Pacific destroyers were in different states of readiness; HMCS Cayuga being the oldest ship was the best equipped at the time, closely followed by HMCS Athabaskan and finally HMCS Sioux which was then in dry dock [1]. The Pacific Fleet received its final orders that day to begin preparation and to cancel all planned training and maintenance: "You are to sail the 'Cayuga', 'Sioux' and 'Athabaskan' from Esquimalt at 16 knots to Pearl Harbor, Wednesday, July 5. , 1950...[1] ". As operational requirements increased throughout the conflict, more and more ships began to be deployed on a rotational basis to the Korean coast, including the Atlantic Fleet: HMCS Haida, Huron, Iriquois, Nootka and HMCS Crusader of the Pacific Fleet from 1950 to 1955 [1]. The conflict Canada's naval contribution had a significant impact on the coalition's efforts to secure South Korea.[5] It was the first post-world...... middle of document ......MRC, Canadian Commander Destroyers Far East, "Korean War Report, part 2", Directorate of History and Heritage (DHH ),81/520/1650-239/187.[4] Canadian Naval Memorial (2014) The Korean War (1950-54).
