The Second World War on the European Theatre saw intense conflict between the Axis forces, which consisted of Nazi Germany, Japan and Italy. Hitler, leader of Germany, created a non-aggression pact with the Soviet Union to prevent them from fighting a two front war in Europe. The Nazi's eventually broke this agreement and invaded Russia, where they attacked a city named Stalingrad, which was inherently named after the Russian dictator Joesph Stalin; the ensuing Russian victory over the Wermacht, or German armed forces. The Battle of Stalingrad changed the tide of the war,due to the halting of the German incursion into Russia, paving the way for the Russians to attack Berlin, the German capital. The German defeat at Stalingrad decimated the seemingly invincible 330,000 strong 6th German Army and resulted in the deaths and captures of 220,000 German soldiers.
