Cnut the Great's invasion of England participant Denmark
In the autumn of 1016, the Danish prince Cnut the Great (Canute) successfully invaded England. Cnut's father, Sweyn Forkbeard, had previously conquered and briefly ruled England for less than five weeks.
The Battle of Brentford was fought in 1016 some time between 9 May (the approximate date Canute landed at Greenwich) and 18 October (the date of the later Battle of Assandun) between the English led by Edmund Ironside and the Danes led by Cnut. It was one of a series of battles fought between Edmund and Canute, ultimately resulting in the lands held by Edmund's father Ethelred the Unready being divided between the two. Edmund was victorious in this particular battle, but ultimately failed to defend the lands inherited from his father.The Battle of Assandun (or Essendune) was fought between Danish and English armies on 18 October 1016. There is disagreement whether Assandun may be Ashdon near Saffron Walden in north Essex or, as long supposed, Ashingdon near Rochford in southeast Essex, England. It ended in victory for the Danes, led by Canute the Great, who triumphed over the English army led by King Edmund Ironside. The battle was the conclusion to the Danish reconquest of England.
The battle is mentioned briefly in Knýtlinga saga which quotes a verse of skaldic poetry by Óttarr svarti, one of Canute's court poets.
