French warplanes have had a good reputation. Even during WWII, it wasn’t the quality of their planes (or tanks) which caused their defeat. It was the way they were used.
I just recently saw a military history show in which it was pointed out that the French had better and more tanks than the Germans when the war began. They just didn’t use them properly.
You have got to be kidding. During the Battle For France their tanks kept breaking down in the middle of the fighting with the Germans. See “The World At War:Battle for France”
Google Maginot Line, and extrapolate that to the rest of the French plan of battle to deter the German invasion of France...how and how long did it work.
The Nieuport and Spad were good against the Huns...but that was in WW1, French bicycles couldn’t fly in WWII.
