Battle of Hatfield Chase
The site of the battle suggests Edwin and his forces may have had to fight on ground not suited for defence. He may have been trapped by the grassy wetlands to the north and the river Don to the east. The armies of Cadwallon and Penda came at him from the west. In the battle one of Edwin's sons, Osfrid, was killed before his father. Edwin was killed and his army scattered. Another son, Eadfrith, was taken prisoner by Penda. Edwin's queen escaped to Kent with two of her children, Osfrid's young son and Bishop Paulinus.
