Something I was pondering over my morning coffee. The German plan in May, 1940 was extremely risky. If the French hadn't been saddled with aged generals thinking in WWI terms, inadequate communications, and had had more time to bring their armored divisions and air force up to snuff, a French counterattack on the long, exposed German flanks could have left the heart of the German panzer forces cut off and vulnerable to defeat in detail. As one historian put it, the German army in 1940 was really two armies; a relatively small, modern, highly trained armored/mechanized force, and a much larger foot and horse mobile force more like the 1918 army, with widely varying levels of training and equipment. So, for the sake of argument, the Luftwaffe gains only partial control of the air over the battle space, allowing succesful attacks on the German supply lines. A major armor battle develops, decimating both sides, but leaving the Germans in a much worse position, cut off in enemy territory and having lost their momentum. The German thrust to the channel ends somewhere around Cambrai. What do the Germans do next? What's Plan B? What are the implications for Hitler and the Nazi Party? Do the Generals boot him out of headquarters and make him a figurehead? Does Stalin see this as a good time to grab the rest of Poland?
