Charles Martel. and the Battle against Saracen Invaders

After the death of Mohammed the Saracens, as Mohammedans are also called, became great warriors. They conquered many countries and established the Mohammedan religion in them. In 711 the Saracens invaded and conquered a great part of Spain and founded a powerful kingdom there, which lasted about seven hundred years. They intended to conquer the land of the Franks next, and then all Europe... In 732 the Saracens again invaded France under Abdalrahman, advanced rapidly to the banks of the Garonne, and laid siege to Bordeaux.
The city was taken by assault and delivered up to the soldiery. The invaders still pressed forward, and spread over the territories of Orleans, Auxerre, and Sens. Their advanced parties were suddenly called in by their chief, who had received information of the rich abbey of St. Martin of Tours, and resolved to plunder and destroy it. Charles during all this time had done nothing to oppose the Saracens, for the reason that the portion of France over which their incursions had been made was not at that time under his dominion, but constituted an independent kingdom, under the name of Aquitaine, of which Eude was king.
But now Charles became convinced of the danger, and prepared to encounter it. Abdalrahman was advancing toward Tours, when intelligence of the approach of Charles, at the head of an army of Franks, compelled him to fall back upon Poitiers, in order to seize an advantageous field of battle.
