the seamen were more numerous, as well as more skilful and experienced, than those of the Romans:  it rendezvoused at Heraclea, not far from Ecnomos.  Between these two places the hostile fleets met, and one of the most obstinate and decisive battles ensued that are recorded in ancient history.  As Polybius has given a very particular account of the manner in which the respective fleets were drawn up, and of all the incidents of the battle, we shall transcribe it from him, because the issue of it may justly be regarded as having proved the Roman superiority at sea, and because 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
