<P> In 383 , the Roman general then assigned to Britain , Magnus Maximus , launched his successful bid for imperial power , crossing to Gaul with his troops . He killed the Western Roman Emperor Gratian and ruled Gaul and Britain as Augustus ( i.e. , as a `` sub-emperor '' under Theodosius I ) . 383 is the last date for any evidence of a Roman presence in the north and west of Britain , perhaps excepting troop assignments at the tower on Holyhead Mountain in Anglesey and at western coastal posts such as Lancaster . These outposts may have lasted into the 390s , but they were a very minor presence , intended primarily to stop attacks and settlement by groups from Ireland . </P>
