However, one must give credit when it is due. Charles the Hammer (Charlegmagnes grandfather) turned the tide of Islamic expansion at the battle of Tours sometimes in the 700's (738?). The religion of peace was raping and pillaging their way over the Pyrenhees. They attacked on horseback and ran smack dab into heavy Frank infantry. Charles the Hammer repelled wave after wave of cavalry attack and then his infantry stomped the fallen horsemen to death. When night fell both sides made their way to their respective camps. Charles went to resume the battle the next day only to find the whipped curs had run away. That marked the high tide of Islamic expansion. His grandson went on to reunify Europe.
Of course, I'm not sure that the French are the true descendantsof the Franks. The Franks were as physically large as the Germani and the Celts (Gauls)which is no longer true. I think there was a lot of intermingling in the centuries to follow.
From Nancy Mitford, The Sun King,Chpt. 2, page 33:
"..the French are divided into Franks and Gauls, Franks, serious and rather cold, the builders and Gauls, adorably frivolous, the destroyers of this nation."
