The king appeared in Normandy at the head of an army and affairs seemed to have come to extremity between the brothers, when the nobility on both sides, strongly connected by interest and alliances, interposed, and meditated an accommodation. The chief advantage of this treaty accrued to William, who obtained possession of the territory of Eu, the towns of Aumule, Fescamp, and other places; but in return he promised, that he would assist his brother in subduing Maine, which had rebelled; and that the Norman barons, attainted in Robert’s cause, should be restored to their estates in England. The two brothers also stipulated, that, on the demise of either without issue, the survivor should inherit all his dominions; and twelve of the most powerful barons on each side swore that they would employ their power to insure the effectual execution of the whole treaty,[*] a strong proof of the great independence and authority of the nobles in those ages.

Prince Henry, disgusted that so little care had been taken of his interests in this accommodation, retired to St. Michael’s Mount, a strong fortress on the coast of Normandy, and infested the neighborhood with his incursions. Robert and William, with their joint forces, besieged him in this place, and had nearly reduced him by the scarcity of water, when the elder, hearing of his distress, granted him permission to supply himself, and also sent him some pipes of wine for his own table. Being reproved by William for this ill-timed generosity, he replied, “What, shall I suffer my brother to die of thirst? Where shall we find another when he is gone?” The king also, during this siege, performed an act of generosity which was less suitable to his character. Riding out one day alone, to take a survey of the fortress, he was attacked by two soldiers, and dismounted. One of them drew his sword in order to despatch him, when the king exclaimed, “Hold, knave! I am the king of England.” The soldier suspended his blow and, raising the king from the ground with expressions of respect, received a handsome reward, and was taken into his service. Prince Henry was soon after obliged to capitulate; and being despoiled of all his patrimony, wandered about for some time with very few attendants, and often in great poverty.
