manned all the available biremes and all the ships with single banks
of oars, and added to this fleet an immense number of small craft.
These carry thirty or forty men apiece and are rigged like Illyrian
cruisers.[547] The small craft he had captured[548] were worked with
bright, parti-coloured plaids, which served as sails and made a fine
show. He chose for review the miniature sea of water where the Rhine
comes pouring down to the ocean through the mouth of the Maas.[549]
His reason for the demonstration--apart from Batavian vanity--was to
scare away the provision-convoys that were already on their way from
Gaul. Cerialis, who was less alarmed than astonished, at once formed
up a fleet. Though inferior in numbers, he had the advantage of larger
ships, experienced rowers, and clever pilots. The Romans had the
stream with them, the Germans the wind. So they sailed past each
other, and after trying a few shots with light missiles they parted.
Civilis without more ado retired across the Rhine.[550] Cerialis
vigorously laid waste the island of the Batavi, and employed the
common device of leaving Civilis's houses and fields untouched.[551]
They were now well into autumn. The heavy equinoctial rains had set
the river in flood and thus turned the marshy, low-lying island into a
sort of lake. Neither fleet nor provision-convoys had arrived, and
their camp on the flat plain began to be washed away by the force of
the current.

Civilis afterwards claimed that at this point the Germans could 24
have crushed the Roman legions and wanted to do so, but that he had
cunningly dissuaded them. Nor does this seem far from true, since his
surrender followed in a few days' time. Cerialis had been sending
secret messages, promising the Batavians peace and Civilis pardon,
urging Veleda and her relatives[552] to change the fortune of a war
that had only brought disaster after disaster, by doing a timely
service to Rome.[553] 'The Treviri,' he reminded them, 'had been
slaughtered; the allegiance of the Ubii recovered; the Batavians
robbed of their home. By supporting Civilis they had gained nothing
but bloodshed, banishment, and bereavement. He was a fugitive exile, a
burden to those who harboured him. Besides, they had earned blame
enough by crossing the Rhine so often: if they took any further
steps,--from the one side they might expect insult and injury, from
the other vengeance and the wrath of heaven.'

Thus Cerial
