jun 22, 1941 - Hitler attacks Russia – Operation Barbarossa
Hitler sent 3 million soldiers and 3,500 tanks into Russia. The Russians were taken by surprise as they had signed a treaty with Germany in 1939. Stalin immediately signed a mutual assistance treaty with Britain and launched an Eastern front battle that would claim 20 million casualties. The USA, which had been supplying arms to Britain under a ‘Lend-Lease’ agreement, offered similar aid to USSR.
