The Regular Infantry Regiments of the British Indian Army

The Two Battalion Regiments 1796 - 1824

In 1796 the infantry of all three presidencies was organised in regiments of two battalions each. From then until 1824 the number of these regiments steadily grew. In 1824 the two battailion structure was abandoned and all battalions became regiments in their own right.
