In truth, however, the year which was coming on, 1069, was another year of crisis in the history of the Conquest. The danger which had been threatening William from the beginning was this year to descend upon him, and to prove as unreal as all those he had faced since the great battle with Harold. For a long time efforts had been making to induce some foreign power to interfere in England and support the cause of the English against the invader. Two states seemed especially fitted for the mission, from close relationship with England in the past,--Scotland and Denmark. Fugitives, who preferred exile to submission, had early sought the one or the other of these courts, and urged intervention upon their kings. Scotland had for the moment formally accepted the Conquest. Denmark had not done so, and Denmark was the more directly interested in the result, not perhaps as a mere question of the independence of England, but for other possible reasons. If England was to be ruled by a foreign king, should not that king on historical grounds be a Dane rather than a Norman? Ought he not to be of the land that had already furnished kings to England? And if Sweyn dreamed of the possibility of extending his rule, at such a time, over this other member of the empire of his uncle, Canute the Great, he is certainly not to be blamed. It is true that the best moment for such an intervention had been allowed to slip by, the time when no beginning of conquest had been made in the north, but the situation was not even yet unfavourable. William was to learn, when the new year had hardly begun, that he really held no more of the north than his garrisons commanded. Perhaps it was a rash attempt to try to establish a Norman earl of Northumberland in Durham before the land had been overawed by his own presence; but the post was important, the two experiments which had been made to secure the country through the appointment of English earls had failed, and the submission of the previous summer might prove to be real. In January Robert of Comines was made earl, and with rash confidence, against the advice of the bishop, he took possession of Durham with five hundred men or more. He expected, no doubt, to be very soon behind the walls of a new castle, but he was allowed no time. The very night of his arrival the enemy gathered and massacred him and all his men but two. Yorkshire took courage at this and cut up a Norman detachment. Then the exiles in Scotland believed the time had come for another attempt, and Edgar, Gospatric, and the others, with the men of Northumberland at their back, advanced to attack the castle in York. This put all the work of the previous summer in danger, and at the call of William Malet, who held the castle for him, the king advanced rapidly to his aid, fell unexpectedly on the insurgents, and scattered them with great slaughter. As a result the Norman hold on York was tightened by the building of a second castle, but Northumberland was
