The 1st Commonwealth Division was the military unit that commanded Commonwealth land forces in the Korean War. The division was a part of the multinational British Commonwealth Forces Korea, with infantry units of the British Army, Canadian Army and Australian Army forming the bulk of the division. Additionally, the New Zealand Army supplied artillery contingents and an Indian medical unit was also attached. As with the "Korean Augmentation To the United States Army" (KATUSA) programme, numerous South Korean troops were seconded to the Commonwealth division to make up numbers under a scheme known as "KATCOM".

History

Background

Following the outbreak of the Korean War, the 27th British Commonwealth Brigade, which was the initial parent formation of Commonwealth army units in Korea, arrived in the peninsula with two British Infantry battalions in August 1950. It was reinforced by the 3rd Battalion, Royal Australian Regiment (3 RAR) in September, and by the 2nd Battalion, Princess Patricia's Canadian Light Infantry (PPCLI), in February 1951. The brigade was subsequently re-constituted as the 28th Commonwealth Brigade in April 1951. Meanwhile, in November 1950, the brigade was joined by the 29th Independent Infantry Brigade, and in May 1951 by the 25th Canadian Infantry Brigade.

Formation

In July 1951, the infantry brigades were combined to form the 1st Commonwealth Division, wherein the unit was 58% British forces, 22% Canadian forces, 14% Australian forces, 5% New Zealander forces, and 1% Indian forces. The 1st Commonwealth Division was part of the US I Corps, which also included the US 1st Cavalry Division, the US 3rd and 25th Infantry Divisions, and the ROK 1st Division. The division occupied the strategically important sector of front on the Jamestown Line, stretching from the Kimpo peninsula on the Yellow Sea coast to a point east of Kumhwa about 6.3 mi, and just 30 mi from the South Korean capital, Seoul.

Dissolution

It was deactivated in 1954 as part of the demobilisation of forces in Korea in the aftermath of the war, being reduced to a Commonwealth Brigade Group, and from May 1956 until its final withdrawal in August 1957 to a Commonwealth Contingent of battalion strength.
