The only details we have on Aelle come from the Saxon Chronicles
In 477ADAelle came to Britain and his three sons Cymen Wlencing and Cyssa, with
three ships, landing at a place called Cymensora. There they killed many
Welsh/British, and drove some in flight into The Weald.
In 485AD Aelle fought the Welsh near the landing place at Mearcredesburnan.
In 491AD Aelle and Cyssa besieged Anderida , near Pevensey, and killed all who were
inside, so there was not one Briton left.
Aelle and his followers spread from their landing place at Shoreham throughout
East Sussex in a matter of decades. Aelle became the first SaxonKing of East Sussex .
