The regiment was raised during the upheaval of the Indian Mutiny, at Ferozepur on 1 July 1857, as the Ferozepore Punjab Battalion. In 1862, the regiment took part in operations in Assam, while during the Second Afghan War of 1878-80, it fought at Peiwar Kotal, Charasiah and Kabul. In 1891, it participated in the Black Mountain Expedition on the North West Frontier of India. Subsequent to the reforms brought about in the Indian Army by Lord Kitchener in 1903, the regiment's designation was changed to 28th Punjabis. During the First World War, they were stationed in Ceylon on garrison duty and was called out to suppress the riots in 1915 which they did brutally. Many atrocities were committed by the Punjabis during Martial Law that prevailed in the country. Following the incidents of the riots, 28th Punjabis was transferred to Mesopotamia, where they fought in the bloody battles on the Tigris Front, as the British made desperate efforts to relieve their besieged garrison at Kut al Amara. In 1917, the regiment took part in the Third Battle of Sannaiyat, the Capture of Baghdad, and the actions at Istabulat and Tekrit. In 1918, the 28th Punjabis participated in the British campaign in Palestine. During the war, the regiment suffered a total of 1423 casualties. It raised a second battalion in 1918, which was disbanded after the war. In 1921, Sepoy Ishar Singh of the 28th Punjabis was awarded the Victoria Cross for exceptional valour during the Waziristan Campaign.
Subsequent history
In 1921-22, a major reorganization was undertaken in the British Indian Army leading to the formation of large infantry groups of four to six battalions. Among these was the 15thPunjab Regiment, formed by grouping the 28th Punjabis with the 25th, 26th, 27th and 29th Punjabis. The battalion's new designation was 4th Battalion 15th Punjab Regiment. During the Second World War, the battalion fought in the Burma Campaign with great distinction. The battalion suffered 921 casualties and was awarded numerous gallantry awards including two Victoria Crosses to Lieutenant Karamjeet Singh Judge and Naik Gian Singh. In 1947, the 15th Punjab Regiment was allocated to Pakistan Army. In 1956, it was merged with the 1st, 14th and 16th Punjab Regiments to form one large Punjab Regiment, and 4/15th Punjab was redesignated as 12 Punjab. During the 1965 Indo-Pakistan War, it fought on the Lahore Front, while in 1971, it served in East Pakistan.
