It would almost seem as if Edward III. and his son never seriously contemplated the subjugation of France: for instead of attempting to take advantage of the virtual dissolution of all government resulting from the defeat of Poitiers and the king's capture, the Black Prince returned to England with his prisoner. The treaty of Bretigny, by which Edward resigned his claims to the French crown, and the French king abandoned all suzerainty over the south-west, was a reasonable solution of the difficulty, if nothing had been at stake but the personal pretensions of the two monarchs. But the national feelings of the French were too strongly roused: the treaty was never carried out. John's son and successor Charles V., or rather his military adviser the Constable Duguesclin, learned wisdom from the crushing defeats of Crecy and Poitiers, and steadily abstained from confronting English armies in the field. All the arts of minor warfare, raids, surprise of castles, cutting off of small parties, were adopted against the English, and the success though slow was steady, and was twofold. Outnumbered from the nature of the case, the English could not but lose in a war thus carried on; and the French subjects of the Black Prince were alienated, through being exposed both to injury at the hands of their own countrymen, and to heavy demands on their resources made by the prince to help him fight a losing game. Gradually things went more and more against the English, until by the time the Black Prince's health failed, and he went home to die, little was left beyond a few towns, which were bound to England by commercial ties. Nor was this all; in the second active stage of the great war, when Henry V. was formally accepted as heir to the French crown, the south-west was the region in which the cause of the Dauphin, the national cause, was most steadily supported.
