expedition with a strategic aim,
a nearer basis for its operations was requisite than Spain or Africa.
Hannibal could not rely for support on a fleet and a fortified
harbour, for Rome was now mistress of the sea. As little did the
territory of the Italian confederacy present any tenable basis. If
in very different times, and in spite of Hellenic sympathies, it had
withstood the shock of Pyrrhus, it was not to be expected that it
would now fall to pieces on the appearance of the Phoenician general;
an invading army would without doubt be crushed between the network of
Roman fortresses and the firmly-consolidated confederacy. The land of
the Ligurians and Celts alone could be to Hannibal, what Poland was to
Napoleon in his very similar Russian campaigns. These tribes still
smarting under their scarcely ended struggle for independence, alien
in race from the Italians, and feeling their very existence endangered
by the chain of Roman fortresses and highways whose first coils were
even now being fastened around them, could not but recognize their
deliverers in the Phoenician army (which numbered in its ranks
numerous Spanish Celts), and would serve as a first support for it to
fall back upon--a source whence it might draw supplies and recruits.
Already formal treaties were concluded with the Boii and the Insubres,
by which they bound themselves to send guides to meet the Carthaginian
army, to procure for it a good reception from the cognate tribes and
supplies along its route, and to rise against the Romans as soon as
it should set foot on Italian ground. In fine, the relations of Rome
with the east led the Carthaginians to this same quarter. Macedonia,
which by the victory of Sellasia had re-established its sovereignty
in the Peloponnesus, was in strained relations with Rome; Demetrius of
Pharos, who had exchanged the Roman alliance for that of Macedonia
and had been dispossessed by the Romans, lived as an exile at the
Macedonian court, and the latter had refused the demand which the
Romans made for his surrender. If it was possible to combine the
armies from the Guadalquivir and the Karasu anywhere against the
common foe, it could only be done on the Po. Thus everything directed
Hannibal to Northern Italy; and that the eyes of his father had
already been turned to that quarter, is shown by the reconnoitring
party of Carthaginians, whom the Romans to their great surprise
encountered in Liguria in 524.
