Battle of Kapyong
1951  

The Battle of Kapyong was fought during the Korean War between United Nations Command (UN) forces - primarily Canadian, Australian, and New Zealand - and the 118th and 60th Divisions of the Chinese People's Volunteer Army (PVA). The fighting occurred during the Chinese Spring Offensive and saw the 27th British Commonwealth Brigade establish blocking positions in the Kapyong Valley, on a key route south to the capital, Seoul. The two forward battalions - the 3rd Battalion, Royal Australian Regiment (3 RAR) and 2nd Battalion, Princess Patricia's Canadian Light Infantry (2 PPCLI), both battalions consisting of about 700 men each""were supported by guns from the 16th Field Regiment (16 Fd Regt) of the Royal Regiment of New Zealand Artillery along with two companies of US mortars and fifteen Sherman tanks. These forces occupied positions astride the valley with hastily developed defences. As thousands of soldiers from the Republic of Korea Army (ROK) began to withdraw through the valley, the PVA infiltrated the brigade position under the cover of darkness, and assaulted the 3 RAR on Hill 504 during the evening and into the following day. The U.S. mortar companies fled the battlefield, expecting an imminent PVA breakthrough at the Kapyong Valley.

Although heavily outnumbered, the 3 RAR and U.S. tanks held their positions into the afternoon of April 24 before they retreated from the battlefield to a reserve position near brigade headquarters, with both sides having suffered heavy casualties. The PVA then turned their attention to the surrounded 2 PPCLI on Hill 677, whose encirclement prevented any resupply or reinforcements from entering. The 2 PCCLI were ordered to make a last stand on Hill 677. During a fierce night battle on April 24/25 the PVA forces were unable to dislodge the 2 PPCLI and sustained enormous losses. The next day, the PVA withdrew back up the valley in order to regroup, and the 2 PPCLI were relieved late on April 26. The fighting helped blunt the PVA Spring Offensive and the actions of the 2 PPCLI and 3 RAR at Kapyong were critical in preventing a breakthrough against the UN central front, the encirclement of U.S. forces in Korea, which were at that point in general retreat, and ultimately, the capture of Seoul. The 2 PPCLI and 3 RAR battalions bore the brunt of the assault and stopped PVA divisional forces estimated at 10,000-20,000 in strength during the hard-fought defensive battle. Today, the battle is regarded as the most famous and significant action fought by the Canadian and Australian armies in Korea, and the most famous battle fought by the Canadian Armed Forces since WWII.
