Lachhiman Gurung

Havildar Lachhiman Gurung, a Gurkha soldier during WW2 lost his right hand while throwing back a grenade from his trench (after two successful attempts at hurling back the grenades), which exploded in his hand. He then "single-handedly" defended his post for over 4 hours against 200 enemy soldiers killing 31 Japanese using only his left hand.
