Turning Points
- Battle of Britain: Stopped Germany taking Britain and turned Hitlers attention to Russia. Also allowed Great Britain to be turned into an unsinkable aircraft carrier. If you want one single turning point I believe this is probably the closest there is. If Germany had won the Battle of Britian the war in Western Europe would probably have been over with a good chance that Germany would have beaten Russia in 1941 as the distractions, Greece and the Balkans, that delayed Germany's attack on Russia would not have happened.
- Battle of Midway: Stopped Japanese expansion and crippled the Japanese fleet.
- Battle of El Alamein: The beginning of the End for German Expansion and stopped German access to additional oil supplies. This turned out to be critical in the long run.
- Battle of Moscow: Stopped the German Advance in Russia and inflicted enormous casualties on the German Army
- Battle of Stalingrad: Stopped the German Army once and for all and started to push the Germans back.
- Battle of Normandy: The beginning of the end for Germany in Western Europe.
- The Atomic Bombs:
I deliberately didn't include Sicily, Italy, Battle of Kursk, Battle of the Bulge etc. While they were major operations and tied down German troops and caused a lot of damage and shortened the I don't believe that they were turning points more of a progression.
My point being that no one battle, except the last, is really THE turning point. If Germany had won the Battle of Britain the Battle for England would have been over very quickly as by this stage Britain didn't really have an effective army. If Midway hadn't happened the way it did then the Allies would still have won. It would have been another setback but the invasion of Mainland USA was beyond the Japanese. Both Germany and Japan knew they could not win a war of attrition. Both aimed for a quick and decisive war. In Japans case to negotiate a peace (which was never going to happen after Pearl Harbour) and in Germany's case to win the war against Russia in the summer of 1941. Net result would have been a prolonging of the war and more casualties but the simple reality is that the US got the A Bomb first and ultimately that would have won the war anyway.
