Among the three key military battles led by Allied forces that tipped the war in favour of the Allies are:
1. Battle of Stalingrad - the attempted German invasion of Russia was topped by the courage of the Soviets in Stalingrad
2. Battle of Midway - the battle of the Pacific islands proved to be costly on the side of the Japanese Imperial Navy
3. D-day - the huge-scale battle marked the Allied advancement to Germany
