Bogart [1] The 25th Canadian Infantry Brigade was Canada's primary combat-formation intending to be sent as part of the British Commonwealth Forces Korea.

Although a full brigade had been trained and armed by 1951, the success of the Inchon Landing meant that only 2nd Battalion, Princess Patricia's Canadian Light Infantry (2 PPCLI) was initially sent.

2 PPCLI earned a Presidential Unit Citation for their actions during the Battle of Kapyong while serving with the 27th British Commonwealth Brigade.

In April 1951, the Chinese People's Liberation Army launched a series of massive offensives across the Korean front, with the intention of recapturing Seoul.
