Kingdom of Sussex
According to the traditional account given in the Anglo-Saxon Chronicle, it was in 477 that a certain Ælle led the invaders ashore at a place called Cymenes ora and defeated the inhabitants. A further battle at a place called Mearcredes burne is recorded under the year 485, and in the annal for 491 we read that Ælle and his son Cissa robbed Anderitum (Pevensey Castle) and killed all the inhabitants.
