The name of St. Sauveur is to be found in the list of officers who accompanied the Conqueror to England; and the records of those times also preserve the remembrance of one Néel, who was slain at Cardiff, in 1078. The troops, however, of the Côtentin, were at the conquest, commanded by Robert, Count of Mortain, half-brother to the duke, who, most probably, was indebted to this near degree of relationship for so proud a mark of distinction. The family of Néel did not retain much longer possession of St. Sauveur: the lord of the castle died in 1092, leaving only a daughter, named Lætitia, who married Jourdain Taisson, or Tesson, and brought to him these possessions as her dowry. After the expiration of about a century, a similar event deprived the Taissons of St. Sauveur. Jane, the last of that family, formed an alliance with the Harcourts, and with them the lordship remained till the middle of the fourteenth century, when the domains of Géoffroy d'Harcourt were confiscated for felony, and the castle would have passed into the hands of a new master, had not the successes of our sovereign, Edward III. interfered, and stopped the effects of the confiscation. History, from this time forward, speaks more decidedly as to the strength of the fortress: at the time of the battle of Poitiers, Géoffroy d'Harcourt maintained himself here, at the head of a numerous garrison, composed of troops from England and Navarre, and, not only bade defiance to the superior force of the French generals, but extended his ravages over the whole of Lower Normandy. The abbey of Lessay, and cathedral of Coutances, particularly suffered from his attacks. To the latter, he had actually laid siege, when a detachment sent against him, by the regent and the states of the kingdom, obliged him to turn his attention homeward; and his forces were defeated, and himself slain. The castle, on this occasion, afforded safe shelter to the fugitives; and, in consequence of Harcourt's death, passing into the hands of the King of England, was, by him, supplied with a garrison of four hundred men, under the command of Jehan Lisle, and was almost immediately afterwards bestowed, by Edward, upon Sir John Chandos, as a reward for his eminent services. The fortifications, under the care of this able captain, underwent a thorough repair in the year 1360; and it is believed that, upon this occasion, the keep was principally, if not altogether, rebuilt; the same broad square tower, which is now standing, and is the principal feature in the ruins. The labor thus bestowed upon St. Sauveur, rendered it one of the principal posts of the duchy. Rymer, by whom it is repeatedly mentioned, expressly states, that our countrymen maintained in it a numerous garrison, who, after the battle of Auray, lorded it without restraint over the neighboring parts, and were guilty of such excesses, that, in 1374, Charles V. then King of France, was induced to send against them a powerful armament, both by sea and land,
