WW2 Battle for Moscow followed closely by the Battle of Stalingrad.
I agree with Spartan ( a very clear thinker).
If the Germans had all their best divisions still existing and a full strength Luftwaffe available in 1944, they would have kicked our arses in Normandy! (a good forum topic)
I doubt we could have got off the beaches! Lucky Hitler went after the Soviets.
Remember folks, on D-Day the only high quality troops that the allies faced was at Omaha beach and look what happened. The Luftwaffe hardly existed. Rommels Panzer units were nowhere near the beaches (not Rommels choice!). The first Panzer division didn't really get into action until the next day around Caen on the Orne River.
The allies overwhelmed the Germans with their airforce and Naval Guns.
PanzerLehr Division was destroyed by US bombers during operation Cobra. Das Reich Panzer Division was shot to pieces from the air as they tried to move to Normandy and then got belted by naval guns at Normandy. Montgomery destroyed the Germans at Caen (and most of Caen itself) due to saturation bombing.
Sure the Germans were still dangerous as a fighting force but by 1944 they had most of the stuffing knocked out of them and were spread way to thin over multiple fronts.
