I'm just reading David Irving's book about Hitler (1933-45) and it appears to me that the Luftwaffe and the Kriegsmarine were both "up" for the coming battles but the Army's generals were a far more reluctant bunch and delayed the invasion of France for a good 6 months due to their hesitancy and pessimism.

I have the greatest respect for Irving as an authority on WW2 and the Third Reich but I'd previously had the impression that the Wehrmacht was ready to take on all-comers and was supremely confident of success so this is a bit of an eye-opener for me, I must say!
