re: #471 Lupin
Let me suggest William Shirer’s COLLAPSE OF THE THIRD REPUBLIC if you haven’t read it.
I’ll second that. Shirer’s tome on Nazi Germany was an insightful memoir by someone who was there: his book about the Fall of France is something else, though: a thorough and comprehensive history.
And, while it doesn’t excuse French mistakes - military OR political - in the lead up to, and the early battles of WWII ( and they were beaucoup) - it puts a serious dent in the “cheese-eating surrender-monkeys” myth. Definitely a worthwhile read.
