possessions, [saying] that it would be very easy, since they excelled
all in valour, to acquire the supremacy of the whole of Gaul. To this he
the more easily persuaded them, because the Helvetii are confined on
every side by the nature of their situation; on one side by the Rhine, a
very broad and deep river, which separates the Helvetian territory from
the Germans; on a second side by the Jura, a very high mountain which is
[situated] between the Sequani and the Helvetii; on a third by the Lake
of Geneva, and by the river Rhone, which separates our Province from the
Helvetii. From these circumstances it resulted that they could range
less widely, and could less easily make war upon their neighbours; for
which reason men fond of war [as they were] were affected with great
regret. They thought, that considering the extent of their population,
and their renown for warfare and bravery, they had but narrow limits,
although they extended in length 240, and in breadth 180 [Roman] miles.

III.--Induced by these considerations, and influenced by the authority
of Orgetorix, they determined to provide such things as were necessary
for their expedition--to buy up as great a number as possible of beasts
of burden and waggons--to make their sowings as large as possible, so
that on their march plenty of corn might be in store--and to establish
peace and friendship with the neighbouring states. They reckoned that a
term of two years would be sufficient for them to execute their designs;
they fix by decree their departure for the third year. Orgetorix is
chosen to complete these arrangements. He took upon himself the office
of ambassador to the states: on this journey he persuades Casticus, the
son of Catamantaledes (one of the Sequani, whose father had possessed
the sovereignty among the people for many years, and had been styled
"_friend_" by the senate of the Roman people), to seize upon the
sovereignty in his own state, which his father had held before him, and
he likewise persuades Dumnorix, an Aeduan, the brother of Divitiacus,
