When it comes to ‘most confirmed kills’ on the battlefield, few would challenge the record of Simo Häyhä. During the Winter War of 1939-40, the Finnish sniper racked up 505 confirmed kills of Soviet soldiers in less than 100 days.
As a sign of respect – and the fact he wore white camouflage especially suited to snow warfare – the Soviets gave Häyhä the nickname ‘White Death’. Soviet soldiers took Häyhä’s impact on the battlefield so seriously that they specifically deployed snipers and artillery against him.
Eventually ‘White Death’ found his luck running out and ended up on the receiving end of a barrel. He was hit in the left side of the jaw by a Soviet bullet. Although he was seriously wounded, he survived the war and was decorated with the Cross of Liberty, the Medal of Liberty and the Cross of Kollaa Battle.
Short answer: A Finnish sniper known as ‘White Death’ killed 505 Soviet soldiers during the Winter War of 1939-40.
