the germans were 80 millions(with austria the twin),france 40 millions only. So, there was nothing to do.

Now, let's add in the populations of the Netherlands, Belgium and Great Britain, all of which had forces on that front as well. The Allied forces and the Germans were virtually equal on 10 May 1940. The Allies had a slight advantage in number and in quality of armor, the Germans had a slight edge in the air.

The difference is that the Germans were much better commanded and organized. There is no way, given competent Allied leadership, that the Germans could have won a total victory using any strategy. Given good Allied leadership, the Manstein Plan should have resulted in the total cutoff and destruction of the best German armored forces.

The German General Staff fully expected to get their asses kicked if they tried an attack. The Manstein Plan was adopted because it was the only plan that gave Germany a chance--provided that Gamelin was an idiot. And he was.

They send 10 divisions, and instead rely on their ally, letting him supporting 90% of the war burden, as Churchill sadly noticed.

BTW, how does it feel to see that even Belgium, a neutral country, disposed of an army 2.5 more important than your

Gamelin told the British he didn't need any more soldiers. He was so sure he was going to win, he even let Poland get wiped out while he faced nothing but a dozen second-rate German divisions.

If he had thought for a second that maybe, just maybe, the Germans would try something different than they did in 1914, he might have won in spite of his arrogance.

They were last seen fighting and dying in a vain attempt to cover the escape of Martin Bormann

The survivors were either shot by General Leclerc in a fit of rage, or enlisted in the Foreign Legion, where they died under incompetent Frog leadership at Dien Bien Phu. The Froggies got their revenge on these Waffen-SS men, if they felt like they needed it.
