As the title suggests, 1962 The War in the Hills is inspired by true events during the 1962 Indo-China War, where not more than a fistful of 125 Indian soldiers, belonging to battalion C Company, led by Major Suraj Singh (Abhay Deol), held off an invading force of 3000 Chinese soldiers at the strategic Galwan Valley, thus thwarting their ultimate goal to capture Ladakh and take over a prime airstrip instrumental to the war effort.
