information as to a suitable spot for landing on the coast of Africa;
so that the army and fleet were still at Lilybaeum, when orders
arrived from the senate that they should return with all possible
speed for the defence of their homes.

In this way, while the two great Roman armies, each in itself equal
in numbers to that of Hannibal, remained at a great distance from the
valley of the Po, the Romans were quite unprepared for an attack in
that quarter. No doubt a Roman army was there, in consequence of
an insurrection that had broken out among the Celts even before the
arrival of the Carthaginian army. The founding of the two Roman
strongholds of Placentia and Cremona, each of which received 6000
colonists, and more especially the preparations for the founding of
Mutina in the territory of the Boii, had already in the spring of 536
driven the Boii to revolt before the time concerted with Hannibal;
and the Insubres had immediately joined them. The colonists already
settled in the territory of Mutina, suddenly attacked, took refuge in
the town. The praetor Lucius Manlius, who held the chief command at
Ariminum, hastened with his single legion to relieve the blockaded
colonists; but he was surprised in the woods, and no course was left
to him after sustaining great loss but to establish himself upon a
hill and to submit to a siege there on the part of the Boii, till
a second legion sent from Rome under the praetor Lucius Atilius
succeeded in relieving army and town, and in suppressing for the
moment the Gaulish insurrection. This premature rising of the Boii
on the one hand, by delaying the departure of Scipio for Spain,
essentially promoted the plans of Hannibal; on the other hand, but
for its occurrence he would have found the valley of the Po entirely
unoccupied, except the fortresses. But the Roman corps, whose two
severely thinned legions did not number 20,000 soldiers, had enough
to do to keep the Celts in check, and did not think of occupying the
passes of the Alps. The Romans only learned that the passes were
threatened, when in August the consul Publius Scipio returned without
his army from Massilia to Italy, and perhaps even then they gave
little heed to the matter, because, forsooth, the foolhardy attempt
would be frustrated by the Alps alone. Thus at the decisive hour and
on the decisive spot there was not even a Roman outpost. Hannibal had
full time to rest his army, to capture after a three days' s
