You guys with this "NEVER" mentality in a "what if" thread...very strange.
It was that "never" mentality that did not expect the Fall of France, the successful invasion of Norway, the massive initial success of Operation Barbarrosa, the success of Rommel in North Africa (including kicking our (American) asses at Kesserine Pass); oh and btw regardless of losses the parachute assault on Crete succeeded despite knowledge of the attack through cracking the enigma code and British naval control of the seas areound the island.
The real "myth" is this invincibility of the English Channel and the British Navy. We are not talking about a major sea engagement between warships or an invasion on a highly fortified zone like the coast of France in 1944, we are talking about an un-prepared (and with the suggested loss of the B.E.F. which did not happen in real life) and ill-defended coast. You guys are depending too much on the Wikipedia version of actual events.
We are supposed to be in "what if" land here folks, not "
Never-Never land." LOL
P.S. although this is the "what would be needed for success in Russia" thread, I stand by my "what if there was only a single front war" which would have made the invasion successful original post.
