The Battle of Mercredesburne was one of three battles fought as part of the conquest of what became the Kingdom of Sussex in southern England. The battles were fought between the Saxon leader Ælle's army and the local Britons.
The Anglo-Saxon Chronicle, states that Ælle arrived in Sussex with three ships and went on to fight at Cymenshore in 477 CE, Mercredesburne in 485, and Pevensey in 491. Ælle became the first king of the South Saxons. The Kingdom of Sussex was eventually annexed by the Kingdom of Wessex in the 9th century and went on to become the county of Sussex, England.
