Only a few days after the Normans had captured Anglesey from the Welsh, Magnus Barefoot appeared with some ships off the coast. Fighting soon began with arrows shot between the Norwegian ships and Norman forces on the shore, but as Hugh of Montgomery was hit with an arrow and killed, the Normans retreated back to England. The defeat of the Normans allowed for the return of the exiled Gruffudd ap Cynan, King of Gwynedd, who thereby regained control of his former lands.
