961 - Battle of Fitjar

Gamle Eiriksson, Sigurd Sleva and Harald Greycloak, three of the sons of Eric Bloodaxe attacked Haakon the good, they lost the battle, but in the final Battle of Fitjar in Hordaland, king Haakon the good was killed. Norway was now under Danish control, and Harald Greycloak II of Norway installed on the Norwegian throne.

The memories of the cruel and atrocious rule under Eric Bloodaxe was not forgotten and the Norwegians did not want one of Eric Bloodaxe`s sons to rule their kingdom. With fire and sword Harald Greycloak and his brother toured the country to enforce their power and crush rebels.

The mightiest enemy was Earl Sigurd of Trøndelagen, they got rid of him one night, they attacked his farm while he was asleep and set fire to his farm so Sigurd burned to death with all his men.

Duke Richard of Normandy had a dispute with the son of the French king Lothar,  Louis.
Count Thibaud of Chartres conquered Evreux and the Normans revenged it with sacking Chartres. In the borderlands bloody battles took place, Richard asked for help from Denmark and the next year a Danish fleet arrived to help.
Shield wall
The local annals record that "the sons of Abloec ravaged Caer Gybi and Lleyn." Abloec (from the Irish Amhlaoibh) meant Olaf Cuaran, ruler of the Dublin Norse. Olaf's sons included Gluniarain ("Iron-Knee"), Sitric Silkenbeard, Ragnall, Aralt, Amancus, and possibly Gillapatraic. Caer Gybi is modern Holyhead, Anglesey. It is interesting to note that Cuaran succumbed to Christianity in 943, and his son Sitric's cross-imprinted coinage shows that he likewise accepted the Christian faith, yet this did not seem to affect their decision to attack churches and monastic institutions outside their own territory.
