“ Negotiations were continued at Oxford, where, the Northumbrians insisting on the recognition of Morcar, Harold yielded on the 28th, and Morcar's election was legalised. On the death of Edward the Confessor Morcar professedly supported Harold (ORDERIC, p. 492, and cp. Florence of Worcester, an. 1066) , but the people of his earldom were dissatisfied, and Harold visited York, the seat of Morcar's government, in the spring of 1066, and overcame their disaffection by peaceful means. In the summer Morcar joined his brother Edwin in repulsing Tostig, who was ravaging the Mercian coast. ”
