France wasn't the first country to surrender. The French military however was the second largest force in Europe behind the Red Army. They had nearing 1.5 million men, 800,000 of which stood on the ''Shield of France" (Maginot Line).
They lacked any kind of knowledge on armoured and mobilised warfare. The BEF was not on the continent to be a holding force, yet France accuses Britain of selfishness for not staying.
On top of that, France did not hand over the French Navy to the Royal Navy. The Royal Navy was forced to destroy the French Navy, which the French still are bitter about when they were in the wrong!
The French Resistance is often given credit for a lot of destruction and disruption when in reality, they were only an information gathering organisation and not even a good one at that.
The French resistance is extremely over-rated, in my opinion.
