peace from Ariovistus, even by giving hostages: and from the Treviri,
[to state] that a hundred cantons of the Suevi had encamped on the banks
of the Rhine, and were attempting to cross it; that the brothers, Nasuas
and Cimberius, headed them. Being greatly alarmed at these things,
Caesar thought that he ought to use all despatch, lest, if thus new band
of Suevi should unite with the old troops of Ariovistus, he [Ariovistus]
might be less easily withstood. Having, therefore, as quickly as he
could, provided a supply of corn, he hastened to Ariovistus by forced
marches.

XXXVIII.--When he had proceeded three days' journey, word was brought to
him that Ariovistus was hastening with all his forces to seize on
Vesontio, which is the largest town of the Sequani, and had advanced
three days' journey from his territories. Caesar thought that he ought
to take the greatest precautions lest this should happen, for there was
in that town a most ample supply of everything which was serviceable for
war; and so fortified was it by the nature of the ground as to afford a
great facility for protracting the war, inasmuch as the river Doubs
almost surrounds the whole town, as though it were traced round it with
a pair of compasses. A mountain of great height shuts in the remaining
space, which is not more than 600 feet, where the river leaves a gap, in
such a manner that the roots of that mountain extend to the river's bank
on either side. A wall thrown around it makes a citadel of this
[mountain], and connects it with the town. Hither Caesar hastens by
forced marches by night and day, and, after having seized the town,
stations a garrison there.

XXXIX.--Whilst he is tarrying a few days at Vesontio, on account of corn
and provisions; from the inquiries of our men and the reports of the
Gauls and traders (who asserted that the Germans were men of huge
