On 12 June 1944, near Ningthoukhong, India, 'B' Company was attempting to stem the enemy's advance when it came under heavy machine-gun and tank machine-gun fire. Ganju Lama, "on his own initiative with great coolness and complete disregard for his own safety", took his PIAT anti-tank weapon and crawled forward. Despite a broken wrist and two other serious wounds to his right leg and left hand he then moved forward, succeeded in bringing the gun into action within 30 yards of the enemy tanks, knocking out two of them (a third was taken out by an anti-tank gun). He continued forward and used grenades on the tanks crews who were trying to escape. Not until he "had killed or wounded them all did he allow himself to be taken back to the Regimental Aid Post" to have his wounds dressed.
