A brother who had acted so vigorously when he himself was not allowed to act at all was dangerous as a neighbour or as a vassal. The memory of his services was humiliating; it was not well to have a brother so near at hand, and in command of so powerful a force, a brother who, if he had at one moment hastened to his elder brother's defence, might at some other moment come with equal speed on an opposite errand. But whatever were their motives, King and Duke agreed to rob their youngest brother of his dominions. And the importance which was attached to this part of the treaty is shown by the speed and energy with which it was carried out. While the recovery of Maine was delayed or forgotten, the recovery of the Côtentin was the first act of the contracting princes after the conclusion of the treaty.
