But the Romans being occasioned to depart againe out of the land, appointed the Britains to make a wall (as had béene aforetime by the emperours Adrian, Antoninus and Seuerus) ouerthwart the countrie [Sidenote: _Beda_ and _Polychron._] from sea to sea, stretching from Penuelton vnto the citie of Aclud, whereby the enimies might be staid from entring the land: but this wall being made of turfs and sods, rather than with stones, after the departure of the Romans was easilie ouerthrowne by the Scots and Picts, which eftsoones returned to inuade the confines of the Britains, and so entring the countrie, wasted and destroied the places [Sidenote: _Beda_ and _Polychron._] before them, according to their former custome. Herevpon were messengers with most lamentable letters againe dispatched towards Rome for new aid against those cruell enimies, with promise, that if the Romans would now in this great necessitie helpe to deliuer the land, they should be assured to find the Britains euermore obedient subiects, and redie at their commandement. Valentinianus (pitieng [Sidenote: _Blondus_. Gallio Ravenna sent into Brittaine.] the case of the poore Britains) appointed another legion of souldiers (of the which one Gallio of Rauenna had the leading) to go to their succours, the which arriuing in Britaine set on the enimies, and giuing them the ouerthrow, slue a great number of them, and chased the residue out of the countrie. The Romans thus hauing obteined the victorie, declared to the Britains, that from thencefoorth they would not take vpon them for euerie light occasion so painefull a iournie, alledging how there was no reason why the Romane ensignes, with such a number of men of warre, should be put to trauell so far by sea and land, for the repelling and beating backe of a sort of scattering rouers and pilfring théeues. Wherfore they aduised the Britains to looke to their dueties, and like men to indeuour themselues to defend their countrie by their owne force from the enimies innasions. And because they iudged it might be an helpe to the Britains, they set in hand to build a wall yet once againe ouerthwart the Ile, in the same place where the emperour [Sidenote: A wall built overthwart the Iland. _Beda_.] Seuerus caused his trench and rampire to be cast. This wall which the Romans now built with helpe of the Britains, was 8 foot in bredth and 12 in length, trauersing the land from east to west, & was made of stone.
