Now the Romans had two facts to consider: First, that circumstances compelled them to face the open sea; and, secondly, that their enemies had the advantage of fast sailing vessels. They therefore took every precaution for keeping their line unbroken and difficult to attack. They had only two ships with six banks of oars, those, namely, on which the Consuls Marcus Atilius and Lucius Manlius respectively were sailing. These they stationed side by side in front and in a line with each other. Behind each of these they stationed ships one behind the other in single file—the first squadron behind the one, and the second squadron behind the other. These were so arranged that, as each ship came to its place, the two files diverged farther and farther from each other; the vessels being also stationed one behind the other with their prows inclining outwards. Having thus arranged the first and second squadrons in single file so as to form a wedge, they stationed the third division in a single line at its base; so that the whole finally presented the appearance of a triangle. Behind this base they stationed the horse-transports, attaching them by towing-ropes to the ships of the third squadron. And to the rear of them they placed the fourth squadron, called the Triarii, in a single line, so extended as to overlap the line in front of them at both extremities. When these dispositions were complete the general appearance was that of a beak or wedge, the apex of which was open, the base compact and strong; while the whole was easy to work and serviceable, and at the same time difficult to break up.
