The Classis Britannica Henry Cleere
Summary
The paper briefly reviews the evidence for the role and history of the
Classis Britannica. It was established in AD 40 or 43 and played a
close-support role for army operations in Britain and the Low Countries.
Its main function was, however, the supply and transportation of material
to army units in Britain; this included the operation of a major iron-
producing industry in the Weald. The fleet disappears from the archaeolog-
ical record towards the middle of the 3rd century, when the Dover base and
the iron-producing establishments were closed down.

importance. It is possible t h at Gesoriacum was the conti-
nental base, loading goods and supplies for shipping to
Britain, and perhaps distributing materials originating from
that province; the production of iron in the Wealden instal-
lations was so large as to imply a considerable export out-
side Britain (Cleere 1976).
During the 2nd century the fleet would appear to have
carried out primarily a support role, supplying and servic-
ing the army units in the military zones of the north and
west and occasionally helping in other ways, as on the
Wall, although it was doubtless called upon for close-
support activities from time to time. The Severan campaign
obviously required a return to close support on a massive
scale, since the operations were such as to require no fewer
than four fleets to be brought under a single command. It
seems likely that the rebuilding of the bath-house at
Beauport Park dates from this period.
The Classis Britannica as a unit disappears from the record
some time towards the middle of the 3rd century. The
Dover base was abandoned and slighted so comprehen-
sively that the later Saxon Shore fort was built on a differ-
ent alignment, and the iron-making establishments at Bar-
down and Beauport Park came to an abrupt end. This was
apparently not the result of any kind of incursion, since the
Beauport Park bath-house was systematically stripped of
re-usable materials such as lead piping and window glass
and allowed to collapse. The latest coins found were of
Caracalla and Severus Alexander at Bardown and Beauport
Park respectively, not incompatible with the date for the
Aries inscription. It is interesting to observe that the Classis
Germanica appears to have disappeared from the record at
about the same time, at least under that name.
Further studies
This incomplete survey of the history and role of the Classis
Britannica raises several interesting lines of research. The
most obvious relates to the mid-3rd century and its disap-
pearance from the archaeological record. It would appear
that the British Fleet as such ceased to exist: the large num-
bers of stamped tiles from the later phases at Beauport Park
and Dover make it seem unlikely that this practice would
have been abandoned when the formation was relocated,
although the fact that the abandonment of the practice of
stamping tiles may have coincided with this move means
that the end of tile stamping must not be interpreted as firm
evidence of disbandment of the fleet. The abondonment of
Dover and the two ironmaking establishments is less easy
to explain in this way. Nevertheless, the army would con-
tinue to require naval forces for supply and close-support
purposes, and so it seems reasonable to postulate a radical
reorganization, which may well have affected fleets on both
sides of the Channel, perhaps involving the disbandment
of the fleets as such and the reallocation of their vessels and
