While the 2nd Gurkhas became one of the four Gurkha regiments to transfer to the British Army, the regiment's 4th Battalion was transferred to the Indian Army as 5th Battalion, 8th Gurkha Rifles (Sirmoor Rifles) where it exists to this day. The first Indian commanding officer of this battalion, Lieutenant Colonel (later Brigadier) Nisi Kanta Chatterji, requested Army Headquarters, to let the battalion keep the title 'Sirmoor Rifles', which was accepted. This battalion saw action in the 1965 Indo-Pakistan War (as part of the 3rd (Independent) Armoured Brigade, 28 and 191 Infantry Brigades) where it stopped the advance of the Pakistani armour to Akhnur in the Battle of the Fatwal Ridge. In the 1971 war against Pakistan, the battalion now as part of the 68th Mountain Brigade, the corps reserves, once again saw fierce action in the defence of Chamb-Akhnur. It launched five successful counterattacks and recaptured the bridge over the Tawi river.
