The battle is described as one the largest tank battles in history since the Battle of Kursk in World War II. Pakistan's invading force, consisting of the 1st Armoured Division and 11th Infantry Division, crossed the International Border and captured the Indian town of Khem Karan. Considering the situation, GOC Indian 4th Mountain Division (Maj. Gen. Gurbaksh Singh) immediately ordered the division to fall back and assume a horseshoe shaped defensive position with Asal Uttar as its focal point. The battle strategy was the brainchild of Brigadier Thomas K.Theogaraj.
