Chronicle of John of Worcester 20 Sep 1066
After these transactions, Harold Harfaager, king of Norway (51), brother of St. Olave the king, suddenly arrived at the mouth of the river Tyne, with a powerful fleet of more than five hundred great ships. Earl Tosti (40) joined him with his fleet, as they had before agreed, and they made all sail into the Humber; and then ascending the river Tyne against the current, landed their troops at a place called Richale. As soon as king Harold (44) received this news, he marched with all expedition towards Northumbria; but, before the king’s arrival, the two brothers, earls Edwin and Morcar, at the head of a large army, fought a battle with the Norwegians on the northern bank of the river Ouse, near York, on the eve of the feast of St. Matthew the Apostle [20th September], being Wednesday; and their first onset was so furious that numbers of the enemy fell before it. But, after a long struggle, the English, unable to withstand the attack of the Norwegians, fled with great loss, and many more of them were drowned in the river than slain in the fight. The Norwegians remained in possession of the field of death; and, having taken one hundred and fifty hostages from York, and leaving there one hundred and fifty hostages of their own, returned to their ships.
Anglo-Saxon Chronicle William The Conqueror. Then on midwinter's day Archbishop Aldred hallowed him to king at Westminster, and gave him possession with the books of Christ, and also swore him, ere that he would set the crown on his head, that he would so well govern this nation as any before him best did, if they would be faithful to him. Nevertheless he laid very heavy tribute on men, and in Lent went over sea to Normandy, taking with him Archbishop Stigand, and Abbot Aylnoth of Glastonbury, and the child Edgar, and the Earls Edwin, Morkar, and Waltheof, and many other good men of England. Bishop Odo and Earl William lived here afterwards, and wrought castles widely through this country, and harassed the miserable people; and ever since has evil increased very much. May the end be good, when God will! In that same expedition (92) was Leofric, Abbot of Peterborough; who sickened there, and came home, and died soon after, on the night of Allhallow-mass. God honour his soul! In his day was all bliss and all good at Peterborough. He was beloved by all; so that the king gave to St. Peter and him the abbey at Burton, and that at Coventry, which the Earl Leofric, who was his uncle, had formerly made; with that of Croyland, and that of Thorney. He did so much good to the minster of Peterborough, in gold, and in silver, and in shroud, and in land, as no other ever did before him, nor any one after him. But now was Gilden-borough become a wretched borough. The monks then chose for abbot Provost Brand, because he was a very good man, and very wise; and sent him to Edgar Etheling, for that the land-folk supposed that he should be king: and the etheling received him gladly. When King William heard say that, he was very wroth, and said that the abbot had renounced him: but good men went between them, and reconciled them; because the abbot was a good man. He gave the king forty marks of gold for his reconciliation; and he lived but a little while after—only three years. Afterwards came all wretchedness and all evil to the minster. God have mercy on it!
87. These facts, though stated in one MS. only, prove the early cooperation of Tosty with the King of Norway. It is remarkable that this statement is confirmed by Snorre, who says that Tosty was with Harald, the King of Norway, in all these expeditions. Vid "Antiq. Celto-Scand." p. 204.
88. i.e. Harold, King of England; "our" king, as we find him afterwards called in B iv., to distinguish him from Harald, King of Norway.
89 Not only the twelve smacks with which he went into Scotland during the summer, as before stated, but an accession of force from all quarters.
90. On the north bank of the Ouse, according to Florence of Worcester; the enemy having landed at Richale (now "Riccal"). Simeon of Durham names the spot "Apud Fulford," i.e. Fulford-water, south of the city of York.
91 It is scarcely necessary to observe that the term "English" begins about this time to be substituted for "Angles"; and that the Normans are not merely the Norwegians, but the Danes and other adventurers from the north, joined with the forces of France and Flanders; who, we shall presently see, overwhelmed by their numbers the expiring, liberties of England. The Franks begin also to assume the name of Frencyscan or "Frenchmen".
92. i.e. in the expedition against the usurper William.
Chronicle of John of Worcester 25 Sep 1066
However, on the fifth day afterwards, viz. on Monday, the seventh of the calends of October [25th September], Harold, king of England (44), having reached York, with many thousand well-armed troops, encountered the Norwegians at a place called Stanford-bridge, and put to the sword king Harold (51) and earl Tosti (40), with the greatest part of their army; and, although the battle was severely contested, gained a complete victory. Notwithstanding, he allowed Harold’s son Olaf, and Paul, earl of Orkney, who had been left with part of the army to guard the ships, to return to their own country, with twenty ships and the relics of the [defeated] army; having first received from them hostages and their oaths.
