The 75th Carnatic Infantry were an infantry regiment of the British Indian Army. They could trace their origins to 1776, when they were raised as the 15th Carnatic Battalion by enlisting men from the 2nd, 6th and 12th Carnatic Battalions.
Their first action was during the Carnatic Wars. Followed by the Battle of Sholinghur in the Second Anglo-Mysore War, they also took part in the Third Anglo-Mysore War and the Third Burmese War.
After World War I the Indian government reformed the army moving from single battalion regiments to multi battalion regiments.[1] In 1922, the 75th Carnatic Infantry became the 2nd Battalion, 3rd Madras Regiment.[2] After independence this new regiment was allocated to the Indian Army.
