He accused Philip of having "violated, without even sending us a challenge, the truce which, out of regard to the sovereign pontiff, we had agreed upon with him, and which he had taken an oath, upon his soul, to keep.

On account whereof we have resolved to proceed against him, him and all his adherents, by land and sea, by all means possible, in order to recover our just rights." It is not quite clear what pressing reasons urged Edward to this decisive resolution.

The English Parliament and people, it is true, showed more disposition to support their king in his pretensions to the throne of France, and the cause of the Count of Montfort was maintaining itself stubbornly in Brittany, but nothing seemed to call for so startling a rupture, or to promise Edward any speedy and successful issue.

He had lost his most energetic and warlike adviser; for Robert d'Artois, the deadly enemy of Philip of Valois, had been so desperately wounded in the defence of Vannes against Robert de Beaumanoir, that he had returned to England only to die.

Edward felt this loss severely, gave Robert a splendid funeral in St.Paul's church, and declared that "he would listen to nought until he had avenged him, and that he would reduce the country of Brittany to such plight that, for forty years, it should not recover." Philip of Valois, on his side, gave signs of getting ready for war.
