ause the details of this accurate historian will
afford us a clear insight into the naval engagements of the ancients.

As there were 330 ships, and each ship had on board 300 rowers, and 120
soldiers, the total number of men in the fleet amounted 140,000. The whole
fleet was formed into four divisions: the first was called the first
legion; the second, the second; and the third, the third legion. The fourth
division had a different name; they were called triarians: the triarii who
were on board this division, being old soldiers of approved valour, who, in
land battles, formed the third line of the legion, and hence obtained their
appellation. The first division was drawn up on the right, the second on
the left, and the third in the rear of the other two, in such a manner that
these three divisions formed a triangle, the point of which was the two
gallies, in which were the consuls, in front of their respective squadrons,
parallel to the third legion, which formed the base of the triangle, and in
the rear of the whole fleet; the triarian division was drawn up, but
extended in such a manner as to out-flank the extremes of the base. Between
the triarian division and the other part of the squadron, the transports
were drawn up, in order that they might be protected from the enemy, and
their escape accelerated and covered in case of a defeat; on board of the
transports were the horses, and baggage of the army.

According to Polybius, the seamen and troops on board the Carthaginian
fleet amounted to 150,000 men. Their admiral waited to see the disposition
of the Roman fleet before he formed his own in order of battle; he divided
it into four squadrons, drawn up in one line; one of these was drawn up
very near the shore, the others stretched far out to sea, apparently for
the purpose of out-flanking the Romans. The light vessels were on the
right, under the command of Hanno; the squadron on the left, which was
formed of heavier vessels, was under the command of Hamilcar.

It is evident from this description of the order of battle of the
Carthaginians, that their line, being so much extended, could easily be
broken; the Romans perceiving this, bore down on the middle with their
first and second divisions. The Carthaginians did not wait the attack, but
retired immediately with the intention of drawing the Romans after them,
and thus by separating, weakening their fleet. The Romans, thinking the
victory was their own, pushed aft
