After the First World War, the two battalions of 89th Punjabis were grouped with four other Burma Battalions (90th, 91st, 92nd Punjabis and 93rd Burma Infantry) to form the 8th Punjab Regiment in 1922. The 1/89th Punjabis became the 1st Battalion and the 2/89th Punjabis the 10th (Training) Battalion of the new regiment. During the Second World War, 1/8th Punjab fought with great gallantry in the Malayan Campaign and again suffered heavy losses. In 1943, the 10th Battalion became the 8th Punjab Regimental Centre. In 1947, the 8th Punjab Regiment was allocated to Pakistan Army. In 1956, it was merged with the Baluch Regiment and 1/8th Punjab was redesignated as 1 Baluch (now 1 Baloch). During the Indo-Pakistan War of 1965, the battalion again distinguished itself at Lahore and Sulemanki, while during the Indo-Pakistan War of 1971 it was deployed in the Shakargarh Sector. Since then, it has served in the Siachen Conflict during 1990–91 and in Liberia as United Nations Peacekeepers in 2004.
