On this day the 5th of August 910, the Danelaw Vikings saw a summary defeat at the hands of the allied forces of Wessex and Mercia, in the Battle of Tettenhall.

This was off the back of decades of raids of Northumbria and settlement of those areas by the Danes, due to the relative security of central England under Alfred the Great.

The Danes, believing the English armies to be otherwise occupied, sought to sail up and raid along the river Avon. They did for a while, but were eventually caught up with the joint Anglo-Saxon force near Tettenhall. The raiders were utterly destroyed and their leaders killed. This led to a generation of no Viking incursion in north England.
