Battle of Aclea
The Battle of Aclea occurred in 851 between the West Saxons led by Æthelwulf, King of Wessex and the Danish Vikings at an unknown location in Surrey. It resulted in a West Saxon victory.
Little is known about the battle and the most important source of information comes from the Anglo-Saxon Chronicle which recorded that:
Aclea means Oak Field, as Asser explained. This should survive as Oakley and there are many examples of that name in England, but none survive in Surrey.
