was soon married to his daughter Eadgyth. At this time, Ethelred ordered a new fleet of warships to be built, on a national scale, but this was weakened when Wulfgeat, who was accused by Eadric's brother Brihtric of treason, turned to piracy. With England now more vulnerable to seaborne invasion, an army led by Thorkell the Tall arrived in 1009 and wreaked havoc in much of the country. While Æthelred wanted to retaliate militarily, Eadric dissuaded him. This indecisiveness led to another two years of conflict and only ended when Eadric — while in London — oversaw the payment of £48,000 to the Danes, at Easter (13 April) in 1012. Also negotiated at this time was the freedom of Ælfheah of Canterbury, but the archbishop refused to be ransomed and was killed by his captors in frustration. In the same year Eadric ravaged St David's in Wales. Invasion In 1013, Sweyn Forkbeard arrived in England with the intention of crowning himself King of England. By the end of 1013, English resistance had collapsed and Sweyn had conquered the country. Eadric's position at this time is not clear, but according to Roger of Wendover, Eadric "crossed over" the channel to Normandy with Queen Emma "and a hundred an forty soldiers". Æthelred followed them in January 1014. However, the situation suddenly changed when Sweyn died on 3 February 1014. The crews of the Danish ships in the Trent, who had previously supported Sweyn, immediately swore their allegiance to his son Cnut; but leading English noblemen sent a proposal to Æthelred to negotiate Æthelred's restoration to the throne. He was required to declare his loyalty to the noblemen, to bring in reforms regarding everything that they previously disliked, and to forgive all that had been said and done against him in his previous reign. Æthelred soon regained his throne with assistance from Olaf Haraldsson; Cnut went back to Denmark, while his allies were punished for their cooperation with him. In 1015, there was a council held in Oxford, to which Eadric invited the brothers Sigeferth and Morcar, who were two thegns from the Seven Burhs in the East Midlands. Unfortunately for them, Eadric had them killed – possibly due to their collaboration with the Danes. This enabled Prince Edmund to confiscate their lands. Return of the Danes Cnut arrived from Denmark in August 1015 at Sandwich in Kent with an invasion force of
