or Hannibal's preference of the land route to that by sea
is less obvious; for that neither the maritime supremacy of the Romans
nor their league with Massilia could have prevented a landing at
Genoa, is evident, and was shown by the sequel. Our authorities fail
to furnish us with several of the elements, on which a satisfactory
answer to this question would depend, and which cannot be supplied by
conjecture. Hannibal had to choose between two evils. Instead of
exposing himself to the unknown and less calculable contingencies of
a sea voyage and of naval war, it must have seemed to him the better
course to accept the assurances, which beyond doubt were seriously
meant, of the Boii and Insubres, and the more so that, even if the
army should land at Genoa, it would still have mountains to cross;
he could hardly know exactly, how much smaller are the difficulties
presented by the Apennines at Genoa than by the main chain of the
Alps. At any rate the route which he took was the primitive Celtic
route, by which many much larger hordes had crossed the Alps: the
ally and deliverer of the Celtic nation might without temerity
venture to traverse it.

Departure of Hannibal

So Hannibal collected the troops, destined for the grand army, in
Cartagena at the beginning of the favourable season; there were 90,000
infantry and 12,000 cavalry, of whom about two-thirds were Africans
and a third Spaniards. The 37 elephants which they took with them
were probably destined rather to make an impression on the Gauls than
for serious warfare. Hannibal's infantry no longer needed, like that
led by Xanthippus, to shelter itself behind a screen of elephants, and
the general had too much sagacity to employ otherwise than sparingly
and with caution that two-edged weapon, which had as often occasioned
the defeat of its own as of the enemy's army. With this force the
general set out in the spring of 536 from Cartagena towards the Ebro.
He so far informed his soldiers as to the measures which he had taken,
particularly as to the connections he had entered into with the Celts
and the resources and object of the expedition, that even the common
soldier, whose military instincts lengthened war had developed, felt
the clear perception and the steady hand of his leader, and followed
him with implicit confidence to the unknown and distant land; and the
fervid address, in which he laid before them the position of their
country and the demands of the
