Cymenshore

Cymenshore was a place in Southern England where, according to the Anglo-Saxon Chronicle, Ælle of Sussex landed in AD 477 and battled the Britons with his three sons Cymen, Wlencing and Cissa, after the first of whom Cymenshore was held to have been named. The spelling Cymenshore is a scholarly modernisation of the Old English Cȳmenes ōra, which is now lost. Its location is unclear but was probably near Selsey.
