The Battle of Brentford was fought in 1016 between invading forces of the Kingdom of Denmark under Cnut and the defending forces of the Kingdom of England led by Edmund Ironside. The battle was fought as part of a campaign by Cnut to conquer England. The battle was a victory for the English, who nevertheless lost a large number of men.
Cnut's invasion continued after the battle and a peace was made after Edmund lost the Battle of Assandun (in Essex) later in the year. Under these terms Cnut gained Mercia and payment for his army, while Edmund held Wessex. Cnut would gain the whole of England after Edmund's death on 30 November 1016.
