William, undismayed amidst this scene of confusion, assembled his forces, and animating them with the prospect of new confiscations and forfeitures, he marched against the rebels in the north, whom he regarded as the most formidable, and whose defeat he knew would strike a terror into all the other malecontents. Joining policy to force, he tried before his approach to weaken the enemy, by detaching the Danes from them; and he engaged Osberne, by large presents, and by offering him the liberty of plundering the sea-coast, to retire, without committing farther hostilities, into Denmark [r]. Cospatric, also, in despair of success, made his peace with the king, and paying a sum of money as an atonement for his insurrection, was received into favour, and even invested with the earldom of Northumberland. Waltheof, who long defended York with great courage, was allured with this appearance of clemency; and as William knew how to esteem valour, even in an enemy, that nobleman had no reason to repent of his confidences [s]. Even Edric, compelled by necessity, submitted to the conqueror, and received forgiveness, which was soon after followed by some degree of trust and favour. Malcolm, coming too late to support his confederates, was constrained to retire; and all the English rebels in other parts, except Hereward, who still kept in his fastnesses, dispersed themselves, and left the Normans undisputed masters of the kingdom. Edgar Atheling, with his followers, sought again a retreat in Scotland from the pursuit of his enemies. [FN [r] Hoveden, p. 451. Chron Abb. St Petri de Burgo, p. 47. Sim. Dun. p. 199.
