And you should look carefully for example at the underlying reason why half a million British soldiers were killed or wounded in Flanders during 1917.
Let me give you a hint. The French soldiers were, to all intents and purposes, on strike. Rather than all out mutiny they had agreed with their officer corps, (largely Petain himself), that they would not abandon their trenches but that they would not partake in any offensive actions until their grievances were addressed. This meant that there was a huge weak point in the allied front and it fell to the British under General Hague, (widely blamed for his stupidity in constantly attacking the Germans), to keep the Germans occupied so they couldn't move divisions opposite the French sector and exploit the weakness they presented.
So, you see, French military history was, yet again, tarnished. I won't mention Agincourt where the English and Welsh were outnumbered as much as six to one and gave the French a severe thrashing...
There is a good reason that the most decorated and highly respected arm of the French military is the French Foreign Legion.
For your edification, stereotypes, especially those that lead to humor, are generally based on a pattern of behaviour that has been observed over time, the French being "cheese eating surrender monkeys" has it's basis in such observation and you can be as offended as you like but all it does is make you look a little precious.
