Charles was highly delighted, and, after the victory, resolutely discharged his kingly part, rewarding, and also punishing. Du Guesclin was made marshal of Normandy, and received as a gift the countship of Longueville, confiscated from the King of Navarre. Certain Frenchmen who had become confidants of the King of Navarre were executed, and Charles V. ordered his generals to no longer show any mercy for the future to subjects of the kingdom who were found in the enemy’s ranks. The war against Charles the Bad continued. Charles V., encouraged by his successes, determined to take part likewise in that which was still going on between the two claimants to the duchy of Brittany, Charles of Blois and John of Montfort. Du Guesclin was sent to support Charles of Blois; “whereat he was greatly rejoiced,” says Froissart, “for he had always held the said lord Charles for his rightful lord.” The Count and Countess of Blois “received him right joyously and pleasantly, and the best part of the barons of Brittany likewise had lord Charles of Blois in regard and affection.” Du Guesclin entered at once on the campaign, and marched upon Auray, which was being besieged by the Count of Montfort. But there he was destined to encounter the most formidable of his adversaries. John of Montfort had claimed the support of his patron, the king of England, and John Chandos, the most famous of the English commanders, had applied to the Prince of Wales to know what he was to do. “You may go full well,” the prince had answered, “since the French are going for the Count of Blois; I give you good leave.” Chandos, delighted, set hastily to work recruiting. Only a few Aquitanians decided to join him, for they were beginning to be disgusted with English rule, and the French national spirit was developing itself throughout Gascony, even in the Prince of Wales’s immediate circle. Chandos recruited scarcely any but English or Bretons, and when, to the great joy of the Count of Montfort, he arrived before Auray, “he brought,” says Froissart, “full sixteen hundred fighting men, knights, and squires, English and Breton, and about eight or nine hundred archers.” Du Guesclin’s troops were pretty nearly equal in number, and not less brave, but less well disciplined, and probably also less ably commanded. The battle took place on the 29th of September, 1364, before Auray. The attendant circumstances and the result have already been recounted in the twentieth chapter of this history; Charles of Blois was killed, and Du Guesclin was made prisoner. The cause of John of Montfort was clearly won; and he, on taking possession of the duchy of Brittany, asked nothing better than to acknowledge himself vassal of the King of France, and swear fidelity to him. Charles V. had too much judgment not to foresee that, even after a defeat, a peace which gave a lawful and definite solution to the question of Brittany, rendered his relations and means of influence with this important province much more to be depended upon than any success which a prolonged war might promise him. Accordingly he made peace at Guerande, on the 11th of April, 1365, after having disputed the conditions inch by inch; and some weeks previously, on the 6th of March, at the indirect instance of the King of Navarre, who, since the battle of Gocherel, had felt himself in peril, Charles V. had likewise put an end to his open struggle against his perfidious neighbor, of whom he certainly did not cease to be mistrustful. Being thus delivered from every external war and declared enemy, the wise King of France was at liberty to devote himself to the re-establishment of internal peace and of order throughout his kingdom, which was in the most pressing need thereof.
