and was attached to the 27th British Commonwealth Brigade. The initial invasion of South Korea by the North Korean People's Army (NKPA) had been broken by General Douglas MacArthur's amphibious landing at Inchon, and so, in what was a complicated war of manoeuvre, 3 RAR was involved in the pursuit of the NKPA back across the 38th parallel. On 21 October 1950, 3 RAR took part in the Battle of Yongyu in an apple orchard north of Pyongyang, the first large-scale engagement fought by a battalion of the regiment. The farthest north 3 RAR would advance into North Korea was the Pakchon–Chongju area following the Battle of Chongju, and it was near here that Lieutenant Colonel Charlie Green, the battalion's commanding officer, was mortally wounded on 30 October 1950. By November 1950, following the Chinese intervention, 3 RAR was withdrawing south along with the rest of the allied Eighth Army, fighting the Battle of Pakchon. However, following a UN counteroffensive a defensive line was established about north of Seoul and it was here in April 1951 that 3 RAR, along with the 2nd Battalion, Princess Patricia's Canadian Light Infantry and supporting UN forces, fought a successful defensive action at the Battle of Kapyong. This battle proved to be the climactic point of the regiment's first year in Korea. By June 1951, 3 RAR moved to a position on the Imjin River under the command of the US I Corps and it was here that the battalion would spend the next two years of the war. The major action fought by the regiment in the second half of 1951 was the Battle of Maryang San, where 3 RAR, under the command of Lieutenant Colonel Frank Hassett, assaulted Hill 317 on 5 October 1951. Known as Operation Commando, Hill 317 was captured after five days of hard fighting. Following this action the war was defined by fixed defences of trenches, bunkers and wire, constant patrolling, and numerous clashes. In April 1952, 3 RAR was joined by 1 RAR and command of the 28th British Commonwealth Brigade, of which they were now a part, passed to an Australian officer as a result. Meanwhile, the expansion of the commitment in Korea to two battalions resulted in the establishment of a regimental depot at Ingleburn in 1952 to train and hold infantrymen for service in Korea. In April 1953, 1 RAR was replaced by 2
