His name was Simo Häyhä.

"During the 1939–1940 Winter War, in temperatures as low as –40 °C, the Finnish sniper undertook a killing spree that saw him single-handedly take the lives of at least 700 men in less than 100 days. Over 500 of these he shot using a standard, bolt-action rifle with non-telescopic sights. Is it any wonder he earned the nickname The White Death among his enemies?"
