Already in 1083 Queen Matilda had died, to the lasting and sincere grief of her husband; and now William's life was about to end in events which were a fitting close to his stormy career. Border warfare along the French boundary was no unusual thing, but something about a raid of the garrison of Mantes, into Normandy, early in 1087, roused William's especial anger. He determined that plundering in that quarter should stop, and reviving old claims which had long been dormant he demanded the restoration to Normandy of the whole French Vexin, of which Mantes was the capital city. Philip treated his claims with contempt, and added a coarse jest on William's corpulence which roused his anger, as personal insults always did, to a white heat. The land around Mantes was cruelly laid waste by his orders, and by a sudden advance the city was carried and burnt down, churches and houses together. The heat and exertion of the attack, together with an injury which he received while riding through the streets of the city, by being thrown violently against the pummel of his saddle by the stumbling of his horse, proved too much for William in his physical condition, and he was carried back to Rouen to die after a few weeks. A monastic chronicler of a little later date, Orderic Vitalis, gives us a detailed account of his death-bed repentance, but it was manifestly written rather for the edification of the believer than to record historical fact. It is interesting to note, however, that while William is made to express the deepest sorrow for the numerous acts of wrong which were committed in the process of the Conquest of England, there is no word which indicates any repentance for the Conquest itself or belief on William's part that he held England unjustly. He admits that it did not come to him from his fathers, but the same sentence which contains this admission affirms that he had gained it by the favour of God. It has been strongly argued from these words, and from others like them, which are put into the mouth of William later in this dying confession, when he comes to dispose of his realms and treasures, that William was conscious to himself that he did not possess any right to the kingdom of England which he could pass on hereditarily to his heirs. These words might without violence be made to yield this meaning, and yet it is impossible to interpret them in this way on any sound principle of criticism, certainly not as the foundation of any constitutional doctrine. There is not a particle of support for this interpretation from any other source; everything else shows that his son William succeeded him in England by the same right and in the same way that Robert did in Normandy. William speaks of himself in early charters, as holding England by hereditary right. He might be ready to acknowledge that it had not come to him by such right, but never that once having gained it he held it for himself and his family by any less right than this.
