Day after day the news became more serious. Morcar accepted the earldom of Northumbria, hurried to York, and placing himself at the head of the Northumbrian forces, marched south, being joined on the way by the men of Lincoln, Nottingham, and Derby, in all of which shires the Danish element was very strong. At Northampton, which had formed part of the government of Tostig, Morcar was joined by his brother Edwin at the head of the forces of Mercia, together with a large body of Welsh. They found the people of Northampton less favourable to their cause than they had expected, and in revenge harried the whole country, killing and burning, and carrying off the cattle as booty and the men as slaves.
Harold bore the brunt of the trouble alone, for, regardless of the fact that half the kingdom was in a flame, King Edward and Tostig continued their hunting expeditions in Wiltshire, in spite of the urgent messages sent by Harold entreating them to return. In the meantime, still hoping that peace might in some way be preserved, Harold sent messages to all the thanes of importance in Wessex, ordering them to prepare to march to London with the whole of their retainers and levies, as soon as they received orders to get in motion. But while he still tarried in Wiltshire the king acceded to Harold's request that he might be empowered to go to Northampton to treat in Edward's name with the rebels.
As soon as he received this permission Harold hastened to Northampton, accompanied by only half a dozen of his thanes, among whom was Wulf. He was received with respect by the rebels, but when their leaders assembled, and in the king's name he called upon them to lay down their arms, to cease from ravaging, and to lay any complaints they might have to make against Tostig before the king or the National Gemot, he met with a flat refusal. They would not listen to any proposition that involved the possibility of the return of Tostig, and boldly said that if the king wished to retain Northumbria as part of his realm he must confirm the sentence of their Gemot upon Tostig, and must recognize their election of Morcar to the earldom.
In all this Harold perceived clearly enough that, although it was the Northumbrian leaders who were speaking, they were acting entirely under the influence of Edwin and Morcar. All that he could obtain was that some of the northern thanes should accompany him to lay their demands before the king himself. Edward, upon hearing, by a swift messenger sent by Harold, of the failure of his attempt to induce the Northumbrians to lay down their arms, reluctantly abandoned the pleasures of the chase, and proceeded to Bretford, near Salisbury, where there was a royal house, and summoned a Witenagemot. As, however, the occasion was urgent, it was attended only by the king's chief councillors, and by the thanes of that part of Wessex.
Between Tostig and Harold the quarrel that the latter had feared had already broken out. Harold was anxious above all things for peace, and although the blow to his own interests and to those of his family, by the transfer of Northumbria from his brother to one of the Mercian earls, was a most serious one, he preferred that even this should take place to embarking in a war that would involve the whole of England. Tostig was so furious at finding that Harold was not willing to push matters to the last extremity in his favour, that he accused him of being the secret instigator of the Northumbrian revolt. The absurdity of such an accusation was evident. It was as much to Harold's interest as to that of Tostig that the great northern earldom should remain in the hands of his family; but an angry man does not reason, and Tostig's fury was roused to the highest point by the outspoken utterances of many of the members of the Witenagemot. These boldly accused him of cruelty and avarice, and declared that many of his acts of severity were caused by his determination, under a show of justice, to possess himself of the wealth of those he condemned. Tostig then rose and declared before the assembly that the whole rising was the work of Harold.
The latter simply denied the charge on oath, and his word was accepted as sufficient. The Witan then turned to the question as to how the revolt was to be dealt with. The king was vehemently in favour of putting it down by force of arms. Tostig was of all the Saxons his favourite friend, and he considered the insult offered to him as dealt against himself. So determined was he, that he sent out orders for the whole of the forces of Wessex to march and join the royal standard. In vain Harold and Edward's wisest councillors endeavoured to dissuade him from a step that would deluge the country in blood, and might lead to terrible disaster. In vain they pointed out that while all the thanes would willingly put their forces at his disposal to resist a foreign foe, or even to repel an invasion from the north, they would not risk life and fortune in an endeavour to force a governor upon a people who hated him, and, as most thought, with good reason.
The king was immovable; but Harold and his councillors took steps quietly to inform the thanes that the Witan was opposed to the order, and that for the present no harm would be done by disregarding the royal mandate. The king, in his anger and mortification at finding himself unable to march against the rebels with an overwhelming force, fell ill, and the control of affairs passed into Harold's hands; and the king, whose fits of passion, though extreme while they lasted, were but short-lived gave him full power to deal with the matter as he thought best.
Harold had done all that he could for Tostig when he went to Northampton, but had failed. There was no alternative now between a great war, followed probably by a complete split of the kingdom, or acquiescence in the demands of the men of the North. He did not hesitate, but in the name of the king confirmed the decisions arrived at by the Gemot of York—recognized Morcar as Earl of Northumbria, and granted a complete amnesty for all offences committed during the rising, on condition only that a general Witenagemot should be held at Oxford. At this meeting Northern and Southern England were again solemnly reconciled, as they had been forty-seven years before at an assembly held at the same place.
