ition between the Carthaginian camp and Cannae and seriously
threatening the latter, to offer battle. A division of 10,000 men
was left behind in the principal Roman camp, charged to capture the
Carthaginian encampment during the conflict and thus to intercept the
retreat of the enemy's army across the river. The bulk of the Roman
army, at early dawn on the and August according to the unconnected,
perhaps in tune according to the correct, calendar, crossed the river
which at this season was shallow and did not materially hamper the
movements of the troops, and took up a position in line near the
smaller Roman camp to the westward of Cannae. The Carthaginian army
followed and likewise crossed the stream, on which rested the right
Roman as well as the left Carthaginian wing. The Roman cavalry was
stationed on the wings: the weaker portion consisting of burgesses,
led by Paullus, on the right next the river; the stronger consisting
of the allies, led by Varro, on the left towards the plain. In the
centre was stationed the infantry in unusually deep files, under the
command of the consul of the previous year Gnaeus Servilius. Opposite
to this centre Hannibal arranged his infantry in the form of a
crescent, so that the Celtic and Iberian troops in their national
armour formed the advanced centre, and the Libyans, armed after the
Roman fashion, formed the drawn-back wings on either side. On the
side next the river the whole heavy cavalry under Hasdrubal was
stationed, on the side towards the plain the light Numidian horse.
After a short skirmish between the light troops the whole line was
soon engaged. Where the light cavalry of the Carthaginians fought
against the heavy cavalry of Varro, the conflict was prolonged,
amidst constant charges of the Numidians, without decisive result.
In the centre, on the other hand, the legions completely overthrew
the Spanish and Gallic troops that first encountered them; eagerly the
victors pressed on and followed up their advantage. But meanwhile, on
the right wing, fortune had turned against the Romans. Hannibal had
merely sought to occupy the left cavalry wing of the enemy, that he
might bring Hasdrubal with the whole regular cavalry to bear against
the weaker right and to overthrow it first. After a brave resistance,
the Roman horse gave way, and those that were not cut down were chased
up the river and scattered in the plain; Paullus, wounded, rode to the
centre to turn or, if
