It is not easy to ascertain the force engaged on each side, but it is certain that the Black Prince, with about ten thousand men-at-arms and as many archers, was superior in numbers and very decidedly superior in the quality of his troops. Nevertheless the force had suffered much hardship, and the men were individually enfeebled by want of food. The Spanish army was distributed into four divisions. The first of these, consisting of dismounted knights, was placed under the command of Bertrand du Guesclin and formed the first line. The remaining three formed the second line; the largest of them, composed of mounted men-at-arms and a rabble of rude infantry, being drawn up in rear of the vanguard, while the other two, made up chiefly of light cavalry copied from the Moorish model, were drawn up on either flank slightly in advance of the second and in rear of the first line. The arrangement of the Black Prince's army was similar but more massive; first came the vanguard under John Chandos, then a second line with two flanking divisions pushed slightly forward, as in the Spanish army, and lastly the third line in reserve. Every man in the English host was dismounted. The battlefield was a level plain; and the sight of the two armies advancing against each other, armour and pennons glancing under the morning sun was, in Froissart's words, great beauty to behold. [Illustration: THE CAMPAIGN OF 1367. _To face page 46_ ] The English archers as usual opened the engagement, and then the divisions of Chandos and du Guesclin, the two most gallant and chivalrous soldiers of their day, met in full shock. In spite of a furious resistance the English, weakened by privation, were for a moment borne back. Chandos was overthrown and went near to lose his life. But meanwhile the English archers in the flanking divisions had driven off the light horse that stood before them, and now wheeling inward enveloped du Guesclin's devoted band on both flanks. The bastard Henry strove gallantly to save the day with the second line, but the Black Prince brought up not only a second line but a third, and the battle was soon over. Then the English men-at-arms flew, as at Poitiers, to their horses, and the defeat was turned into a rout. A rapid torrent, spanned by but a single bridge, barred the retreat of the fugitives; the narrow passage was choked by the press of the flying, and thousands were taken or slain.
