But such was the power of Alfric, that he again forced himself into authority; and though he had given this specimen of his character, and received this grievous provocation, it was found necessary to intrust him anew with the government of Mercia. This conduct of the court, which, in all its circumstances, is so barbarous, weak, and imprudent both merited and prognosticated the most grievous calamities. {993.} The northern invaders, now well acquainted with the defenceless condition of England, made a powerful descent under the command of Sweyn, king of Denmark, and Olave king of Norway; and sailing up the Humber, spread on all sides their destructive ravages. Lindesey was laid waste; Banbury was destroyed; and all the Northumbrians, though mostly of Danish descent, were constrained either to join the invaders, or to suffer under their depredations. A powerful army was assembled to oppose the Danes, and a general action ensued; but the English were deserted in the battle, from the cowardice or treachery of their three leaders, all of them men of Danish race, Frena, Frithegist, and Godwin, who gave the example of a shameful flight to the troops under their command. Encouraged by this success, and still more by the contempt which it inspired for their enemy, the pirates ventured to attack the centre of the kingdom; and entering the Thames in ninety-four vessels, laid siege to London, and threatened it with total destruction. But the citizens, alarmed at the danger, and firmly united among themselves, made a bolder defence than the cowardice of the nobility and gentry gave the invaders reason to apprehend; and the besiegers, after suffering the greatest hardships, were finally frustrated in their attempt. In order to revenge themselves, they laid waste Essex, Sussex, and Hampshire; and having there procured horses, they were thereby enabled to spread through the more inland counties the fury of their depredations. In this extremity, Ethelred and his nobles had recourse to the former expedient; and sending ambassadors to the two northern kings, they promised them subsistence and tribute, on condition they would, for the present, put an end to their ravages, and soon after depart the kingdom. Sweyn and Olave agreed to the terms, and peaceably took up their quarters at Southampton, where the sum of sixteen thousand pounds was paid to them. Olave even made a journey to Andover, where Ethelred resided; and he received the rite of confirmation from the English bishops, as well as many rich presents from the king. He here promised that he would never more infest the English territories; and he faithfully fulfilled the engagement. This prince receives the appellation of St. Olave from the church of Rome; and, notwithstanding the general presumption, which lies either against the understanding or morals of every one who in those ignorant ages was dignified with that title, he seems to have been a man
