Throughout Caesar’s campaigns in Gaul, Diviciacus, chieftain of the Aedui, was constantly
at Caesar’s side, urging his Celtic confederates to submit peacefully to Roman domination.
As the Roman war machine rolled on, more and more Gallic warriors joined its legions.
So far, in his march through Gaul, Caesar had had good excuses for his aggression
- the invitations of the Aedui, the attacks of the Bellgae. But in 57 B.C. He sent
a detachment under the comand of a subordinate to the lands of the Atlantic coast.
Their subsequent reduction of this peaceful area was unprovoked and patently revealed
Caesar’s intention to conquer the whole of Gaul. The next year, recovering from the
shock of Roman occupation, the Celts of Brittany, led by the Veneti tribe, took up
arms. The Veneti were a maritime power, deriving much wealth from their shipping
of British tin from Cornwall to Gallic traders. Their strongholds stood on headlands
or islands in tidal estuaries which were cut off from the land for most of the time
by the sea.
As the Romans approached the Atlantic coast, the Veneti and Breton forces strengthened
their fleet and gathered fellow tribesman, including many warriors from Britain.
Caesar was secure in his excuse this time: the quelling of a tribe who had already
submitted and the punishment of a terrorist kidnapping of Roman envoys. He again
employed the assistance of the friendly Celts who supplied him with Gallic ships
built along the loire. With his land forces he tried to capture the Breton strongholds.
Using all the ingenuity of Roman Seigecraft, he had huge dykes constructed to the
island fortresses of the Celts But no sooner had these been completed then the defenders
simply evacuated into awaiting ships and moved to another fortress. The lack of natural
harbours and rough ocean weather made Roman assaults by sea difficult.
The considerable advantage of knowing the local seaways lay very much with the Veneti.
But, as elsewhere, there was no shortage of Celts ready to assist the Romans.
Local Gauls presented the Romans with a rapidly-built fleet which cannot have been
very different from that of the Veneti.. “They have flat bottom”, wrote Caesar of
the Gallic ships, “which enables them to sail in shallow coastal water. Their high
bows and sterns protect them from heavy seas and violent storms, as do their strong
hulls made entirely from oak. The cross-timbers - beams a foot wide - are secured
with iron nails as thick as a man’s thumb. Their anchors are secured with chains
not ropes, while their sails are made of raw hide or thin leather, so as to stand
up to the violent Atlantic winds.”
These are Caesar’s words of the description of the Bretons Gallic warships. Is this
where the Vikings, to come 6 centuries later, got their incredible ideas for the
longships? Perhaps we will never know, but the description of the Gallic ships is
uncannily similar in form, if not construction.
When Caesar’s fleet was ready, he confronted the Veneti in the Loire estuary. As
the boasts crashed into each other, legionaires and their Gallic allies watched the
battle from the cliff-tops. The Romans in the boats - all land soldiers - were at
a loss as to how to tackle the Veneti Gallic seamen. They improvised with scythes
attached to long poles and used them to cut the Celtic rigging. With their sails
fluttering uselessly and apparently no oars to assist them, the Celtic Bretons and
their British Celtic allies, soon lost control. Several Roman boats then locked onto
individual Celtic ships and boarded them.
