Dissertation on the Roman
Wall
A Dissertation on the Roman WALL, with
Remarks.
IN the present situation of affairs, a plan of the method
antiently practic'd by the vigilant Romans for
securing the isthmus of Britain, with some remarks on
it, will not I believe be unacceptable to the public.
Agricola, lieutenant to the emperor Domitian,
seems to be the first of the Roman generals that
extended his conquests after the reduction of the
Brigantes to this isthmus. Such of the Britons
as escaped his arms, retreated behind the long chain of
mountains on the skirts of Yorkshire and
Northumberland. But these strong barriers of nature
avail'd little against the persevering courage of the
Roman soldiery; they carry'd on military roads, and
supported them with garrisons, thro' the most inaccessible
desarts of Britain, and united territories which the
mountains had sever'd in vain. Whilst any land remain'd the
Britons fled before the Romans, 'till getting
beyond the isthmus at Carlisle, a more extended and
hilly country, it afforded them not only a safer retreat,
but the liberty of returning through defiles of thick and
entangling forests, yet unknown to the Romans. But it
was not long that the natives could play this game, under
the attentive eye of Agricola; he soon perceiv'd the
inconvenience, and found out a remedy. He fixed a series of
stations in a line across the isthmus, at regular intervals,
and, garrisoning them with what soldiery he could spare,
proceeded with the rest to reduce the North. At
Bodotria another isthmus occurr'd, much straiter than
the first; this he fortify'd in like manner, and recall'd
the soldiers to keep garrison there as in the former,
marching to subdue the countries by the Grampian
mountains. But before he could complete his scheme, he was
recall'd, and the Caledonians, resuming their
independency, carry'd their arms to his first line of
stations again.
Hadrian afraid of the consequence, and with a view to
suppress the nocturnal excursions of the enemy, through the
intervals of Agricola's garrisons, which they
frequently perform'd with astonishing celerity and silence,
connected all these stations by a mud-wall, two aggers, a
ditch, and military way.
Antoninus Pius his successor found means to curb the
insolence of the Caledonians, and confine them to
their mountains once more, driving them beyond the second
isthmus, and fortifying it with an admirable wall of
hewn-stone from sea to sea, along the series of
Agricola's stations.
After his death Britain was again neglected, and the
Caledonians overthrowing his wall stretched their
limits to Agricola's first stations, and the wall was
never more recover'd from them by the Romans. Whether
the succeeding emperors disregarded such a conquest as
useless, or whether it was not in their power to retake it,
is of no consequence to determine; probably their attention
to affairs on the continent, afforded little time for their
securing Britain.
After the death of Antoninus, Severus was the first
of the Roman emperors that turn'd his eye to
Britain, the island being well nigh lost by a general
defection. He reduc'd them to obedience once more after
several victories, promoted his boundaries to
Hadrian's wall, and built one of hewn stone at this
isthmus, similar to Antonine's, from sea to sea,
which continu'd the limit of the Roman empire in
Britain, 'till their final departure from the island.
But 'tis to be observ'd that he had several advanc'd
stations as exploratory garrisons, for giving signals on any
alarms, and preventing surprize: As at *
Beu-castle, Netherby, Middleby, &c. (See the
map), besides the principal encampments on the wall,
each of which appears to have consisted of 1000 foot and 150
horsemen, by the stone lately found at Cast-steeds
and publish'd in the Magazine for 1741. p.650. See
also Mag. 1742, p.30, 76, 135.
Such was the vigilance, resolution, and military application
of the conquerors of the world. They turn'd not their
soldiers into an army of useless observation at the East end
of the wall, when the West was ravag'd with thieves, nor,
amid their banquets, were they idle auditors of the
oppression of their friends, without putting a hand to
deliver them. Without any other qualifications but the
virtues of a military face, and the sincerity of a
Roman heart, they disregarded the inclemencies of a
British air, nor dreaded the point of a
Caledonian lance. Embroidery was no part of their
garb, and took up no part of their time; as they dress'd not
like mountebanks, they fought not like poltroons. Thus they
liv'd, and dying left behind them such
