But France, even with her southwestern corner in English hands, was still a very warlike power, far richer and more populous than her rival. Single Provinces were so great that they were stronger than many a kingdom. Normandy in the north, Burgundy in the east, Brittany in the west and Languedoc in the south were each capable of fitting out a great army of their own. Therefore the brave and spirited John, watching from Paris this insolent raid into his dominions, sent messengers in hot haste to all these great feudatories as well as to Lorraine, Picardy, Auvergne, Hainault, Vermandois, Champagne, and to the German mercenaries over his eastern border, bidding all of them to ride hard, with bloody spur, day and night, until they should gather to a head at Chartres.
There a great army had assembled early in September, whilst the Prince, all unconscious of its presence sacked towns and besieged castles from Bourges to Issodun, passing Romorautin, and so onward to Vierzon and to Tours. From week to week there were merry skirmishes at barriers, brisk assaults of fortresses in which much honor was won, knightly meetings with detached parties of Frenchmen and occasional spear-runnings where noble champions deigned to venture their persons. Houses, too, were to be plundered, while wine and women were in plenty. Never had either knights or archers had so pleasant and profitable an excursion, so that it was with high heart and much hope of pleasant days at Bordeaux with their pockets full of money that the army turned south from the Loire and began to retrace its steps to the seaboard city.
But now its pleasant and martial promenade changed suddenly to very serious work of war. As the Prince moved south he found that all, supplies had been cleared away from in front of him and that there was neither fodder for the horses nor food for the men. Two hundred wagons laden with spoil rolled at the head of the army, but the starving soldiers would soon have gladly changed it all for as many loads of bread and of meat. The light troops of the French had preceded then and burned or destroyed everything that could be of use. Now also for the first time the Prince and his men became aware that a great army was moving upon the eastern side of them, streaming southward in the hope of cutting off their retreat to the sea. The sky glowed with their fires at night, and the autumn sun twinkled and gleamed from one end of the horizon to the other upon the steel caps and flashing weapons of a mighty host.
