Simo Häyhä (1905-2002) was a Finnish sniper in the Winter War (Talvisota) 1939-40. Mainly equipped with a modified Mosin-Nagant he killed more than 500 soviet soldiers. Thereby he has the highest recorded number of confirmed kills in any major war. The soldiers of the Red Army nicknamed him “The White Death” (Russian: Белая смерть, Belaya Smert).
The Russian forces were absolutely terrified of Häyhä. They attempted numerous times to kill him, from sending teams of countersnipers after him (none came back alive) to artillery bombing any place they thought he was hiding. Needless to say, each of these attempts was met with failure, and Simo continued to utterly stomp any enemy who came within his sights. Eventually, the Russians had a stroke of luck when one sniper, after Simo had pretty much wiped out the whole team, managed to shoot him through the jaw with an exploding bullet, blowing half of his cheek away. Incredibly, Simo managed to pick up his gun and kill the sniper, and walked back to his nearest unit, where he was sent to the hospital, whereupon he slipped into a coma. A ceasefire was ordered, and eleven days later, on the day Simo awoke, the Russian army withdrew.
