BOB a mistake ? --- The Battle of France

[Rama]

There are many other books than just Spears one you should read to have a somewhat unbiased view of the French Campaign.
Some of his thoughts are correct (you find the same in other testimonies), other contradictory to other historian views.

The main responsability of the defeat are not to be searched On Weygand side. When he overtook the command, the disaster was allready there.
I agree French were poorly leaded, but the main responsibles were Gamelin and the HHQ, and on a lower level, army generals like Huntziger that were more concerned about their own cariers than being efficient in the field.

It's also false to say that "logistic support required to supply replacement and new equipment to front line was almost non existent"... it was ok until the retreat when everything get disorganized... and it was much better than other sectors, like transmission for example (based mostly on.... civilian phone and letters transmitted by motorbikers "estafettes"... it took around 3 days for an information to go from the front to the HQ...).
The biggest problem was.... there was no available replacement...
All the army strategical reserve had been used for the stupid northern move with objective too keep Netherland into the war (move that of course failed badly).
... you can't replace a company with emptyness, even if you have the railways, the trucks and the drivers...
