when we remember that Charles had no standing army, and the independent spirit of the Frank warriors who followed his standard, it seems most probable that it was not in his power to adopt the cautious policy of watching the invaders, and wearing out their strength by delay. So dreadful and so widespread were the ravages of the Saracenic light cavalry throughout Gaul, that it must have been impossible to restrain for any length of time the indignant ardor of the Franks. And, even if Charles could have persuaded his men to look tamely on while the Arabs stormed more towns and desolated more districts, he could not have kept an army together when the usual period of a military expedition had expired.
