In order to restore England to such a state of tranquillity as it was then capable of attaining, nought was wanting but the subjection of the Northumbrians, who, assisted by the scattered Danes in Mercia, continually infested the bowels of the kingdom. Edward, in order to divert the force of these enemies, prepared a fleet to attack them by sea, hoping that when his ships appeared on their coast, they must at least remain at home, and provide for their defence. But the Northumbrians were less anxious to secure their own property, than greedy to commit spoil on their enemy; and, concluding that the chief strength of the English was embarked on board the fleet, they thought the opportunity favorable, and entered Edward’s territories with all their forces. The king, who was prepared against this event, attacked them, on their return, at Tetenhall in the county of Stafford, put them to rout, recovered all the booty, and pursued them with great slaughter into their own country. All the rest of Edward’s reign was a scene of continued and successful action against the Northumbrians, the East Angles, the Five-burgers, and the foreign Danes, who invaded him from Normandy and Brittany. Nor was he less provident in putting his kingdom in a posture of defence, than vigorous in assaulting the enemy. He fortified the towns of Chester, Eddesbury, Warwick, Cherbury, Buckingham, Towcester, Maldon, Huntingdon, and Colchester. He fought two signal battles at Temsford and Maldon.[*] [* Chron. Sax. p. 10, Flor. Wigorn. p. 6.] He vanquished Thurketill, a great Danish chief, and obliged him to retire with his followers into France, in quest of spoil and adventures. He subdued the East Angles, and forced them to swear allegiance to him: he expelled the two rival princes of Northumberland, Reginald and Sidroc, and acquired, for the present, the dominion of that province: several tribes of the Britons were subjected by him; and even the Scots, who, during the reign of Egbert, had, under the conduct of Kenneth, their king, increased their power by the final subjection of the Picts, were nevertheless obliged to give him marks of submission.[*] In all these fortunate achievements, he was assisted by the activity and prudence of his sister Ethelfleda, who was widow of Ethelbert, earl of Mercia, and who after her husband’s death, retained the government of that province. This princess, who had been reduced to extremity in childbed, refused afterwards all commerce with her husband; not from any weak superstition, as was common in that age, but because she deemed all domestic occupations unworthy of her masculine and ambitious spirit.[**] She died before her brother; and Edward, during the remainder of his reign, took upon himself the immediate government of Mercia, which before had been intrusted to the authority of a governor.[***] The Saxon Chronicle fixes the death of this prince in 925 his kingdom devolved to Athelstan, his natural son.
