The Battle of the Imjin River, also known as the Battles of Kumgul-san, P'ap'yong-san and Solma-ri or the Battle of Xuemali, took place 22–25 April 1951 during the Korean War. Forces from People’s Republic of China attacked UN positions on the lower Imjin River in an attempt to achieve a breakthrough and recapture the South Korean capital Seoul. The attack was part of the Chinese Fifth Phase Campaign, also known as the Chinese Spring Offensive, whose aim it was to regain the initiative on the battlefield after a successful UN counter-offensive in March 1951 had allowed UN forces to establish themselves past the 38th parallel at Line Kansas. The section of the UN line where the battle of the Imjin River took place was defended primarily by British forces of 29th Infantry Brigade. 29th Infantry Brigade consisted of three British and one Belgian infantry battalions supported by tanks and artillery. Despite facing a numerically superior enemy, 29th Infantry Brigade held its positions for 3 days. When the units of 29th Infantry Brigade were ultimately forced to fall back, their actions in the Battle of the Imjin River together with those of other UN forces, for example in the Battle of Kapyong, had blunted the impetus of the Chinese offensive and allowed UN forces to retreat to prepared defensive positions north of Seoul where the Chinese were halted.
