This latter province, however, John had the imprudence again to dismember by bestowing it on Philip, his fourth son, the object of his most tender affections;[*] a deed which was afterwards the source of many calamities to the kingdom.
John was succeeded in the throne by Charles the dauphin, a prince educated in the school of adversity, and well qualified, by his consummate prudence and experience, to repair all the losses which the kingdom had sustained from the errors of his two predecessors.

Contrary to the practice of all the great princes of those times, which held nothing in estimation but military courage, he seems to have fixed it as a maxim never to appear at the head of his armies; and he was the first king in Europe that showed the advantage of policy, foresight, and judgment, above a rash and precipitate valor.

The events of his reign, compared with those of the preceding, are a proof how little reason kingdoms have to value themselves on their victories, or to be humbled by their defeats; which in reality ought to be ascribed chiefly to the good or bad conduct of their rulers, and are of little moment towards determining national characters and manners.
Before Charles could think of counterbalancing so great a power as England, it was necessary for him to remedy the many disorders to which his own kingdom was exposed.

He turned his arms against the king of Navarre, the great disturber of France during that age; he defeated this prince by the conduct of Bertrand du Guesclin, a gentleman of Brittany, one of the most accomplished characters of the age, whom he had the discernment to choose as the instrument of all his victories:[**] and he obliged his enemy to accept of moderate terms of peace.

Du Guesclin was less fortunate in the wars of Brittany, which still continued, notwithstanding the mediation of France and England: he was defeated and taken prisoner at Auray by Chandos: Charles of Blois was there slain, and the young count of Mountfort soon after got entire possession of that duchy.[*] But the prudence of Charles broke the force of this blow: he submitted to the decision of fortune: he acknowledged the title of Mountfort, though a zealous partisan of England; and received the proffered homage for his dominions.
