he cavalry
with C. Trebonius, the lieutenant, for the purpose of foraging, they
flew upon the foragers suddenly from all quarters, so that they did
not keep off [even] from the standards and the legions. Our men,
making an attack on them vigorously, repulsed them; nor did they cease
to pursue them until the horse, relying on relief, as they saw the
legions behind them, drove the enemy precipitately before them, and,
slaying a great number of them, did not give them the opportunity
either of rallying, or halting, or leaping from their chariots. After
this retreat the auxiliaries departed; nor after that time did the
enemy ever engage with us in very large numbers.

Caesar, discovering their design, leads his army into the territories
of Cassivelaunus[40] to the river Thames, which river can be forded in
one place only, and that with difficulty. When he had arrived there,
he perceives that numerous forces of the enemy were marshaled on the
other bank of the river; the bank also was defended by sharp
stakes[41] fixt in front, and stakes of the same kind fixt under the
water were covered by the river. These things being discovered from
[some] prisoners and deserters, Caesar, sending forward the cavalry,
ordered the legions to follow them immediately. But the soldiers
advanced with such speed and such ardor, tho they stood above the
water by their heads only, that the enemy could not sustain the attack
of the legions and of the horse, and quitted the banks, and committed
themselves to flight.

Cassivelaunus, as we have stated above, all hope [rising out] of
battle being laid aside, the greater part of his forces being
dismissed, and about 4,000 charioteers only being left, used to
observe our marches and retire a little from the road, and conceal
himself in intricate and woody places, and in those neighborhoods in
which he had discovered we were about to march, he used to drive the
cattle and the inhabitants from the fields into the woods; and, when
our cavalry, for the sake of plundering and ravaging the more freely,
scattered themselves among the fields, he used to send out charioteers
from the woods by all the well-known roads and paths, and, to the
great danger of our horse, engaged with them; and this source of fear
hindered them from straggling very extensively. The result was that
Caesar did not allow excursions to be made to a great distance from the
main body of the legions, and ordered that damage should be done
