Before it could settle down in its new location, the division was asked to move to the Akhnoor sector. The division at this time was re-designated as 10 Infantry Division. It was asked to take over operational command over 80 and 191 Infantry Brigades by 15 September 1965.

They captured a large number of posts along the Kalidhar and Nathua-Tibba-Laleali ridges. On 1 September 1965, as part of Operation Grand Slam, Pakistani forces launched an offensive in Akhnoor sector with three infantry brigades, two armoured regiments (with M48 Pattons and M-36 Sherman B-2 tank destroyers) and artillery support. This attack overwhelmed the two forward companies of 15 Kumaon and came to striking distance of HQ, 191 Infantry Brigade. An urgent request for air support proved counter-productive, as it did little damage to the enemy, but took a heavy toll due to friendly fire. The AMX squadron of 20 Lancers put up a gallant fight, avoiding a disaster. In face of the overwhelming Pakistani attack, the XV Corps headquarters pushed in 6 Rajput, 20 Lancers and 28 Infantry Brigade. 191
