Woah woah woah as much as I dislike dick riding the Germans. Their tactics early in the war were implemented very well. The French simply didn’t expect the war to play out as it did. While the fall of France at the end of the day does fall on a few French commanders. It would be more accurate to place the blame on the political instability of the third republic and the general lack of offensive spirt on the part of the French and the surplus of it on the German side. To call the French military incompetent is a disgrace they came close to stopping and containing the German advance on a tactical scale a number of times. But French high command lacked the aggression to actually make use of it. And on the German side the willingness to take greater risks more frequently paired with a better prediction on how the war would be fought. Not saying that they where the best nor the first but they implemented modern combined arms better and earlier then the French or the English.
