A quinquereme had three hundred rowers and a hundred and twenty marines; to these rowers the triremes could oppose but a hundred and twenty, who therefore were able to do as little against them, as a frigate or a brigantine would against a ship of the line. This accounts for the statement, that the Romans had had no fleet at all; and yet they had built triremes for the passage to Sicily. They wanted therefore a model, from which the ships might be built on correct principles, so that they could be worked with ease; and they might certainly have sent for a shipbuilder to Greece, or to Egypt, to Ptolemy Philadelphus, with whom they were already allied, and have fetched a model thence; for the ancients indeed built from models. But it so happened that a Carthaginian ship of war was driven ashore, and from it they built a hundred and twenty quinqueremes.[3] These were indeed very unwieldy, and the Romans had not the number of sailors which they wanted, that is to say, more than 30,000. They were therefore obliged to man them with levies from the inland districts, and with slaves, as the Russian ships are by conscription in the interior of the empire;--for, the seamen from Etruria and the Greek towns were by no means sufficient (Polybius goes too far, in stating that they had had no able seamen at all): these were trained to ply the oars upon scaffoldings on dry ground. This drilling, as it is told to us, seems to be utterly ridiculous; and the Carthaginians must have been altogether unlike our nations, if on this occasion a whole crowd of caricatures were not published among them. There was in those times the same contrast between a Roman and a Carthaginian ship, which there is now-a-days between a Russian and an English or American man of war. But the Romans, being great in this as they were in all things, devised the means of overcoming this disadvantage. Their fleet was unable to make head against the Carthaginians in the ordinary tactics; and it was very likely at that very time, and not at a later one, that the idea was conceived of ridding the sea-fight of all artificial evolutions, and rather making ship fight against ship. For it required the greatest skill to manage and steer the ships against wind and tide in the same way as a rider manages his horse, so as to shatter the enemy’s vessel by means of the _rostrum_, and to tear off the benches of the rowers; this was more than the Romans dared to think of. Wherever an enemy is to be met who is greatly superior in skill, the only way of conquering is by employing masses, or some unexpected invention. Thus Carnot gained the victory for the French, by opposing masses to the thin lines of the enemy; the battle of Wattignies (15, 16 Oct. 1793) is the turning point of the modern history of warfare, the end of the old, and the beginning of the new tactics. General Hoche had recourse to the same system in Lorraine; by masses the Americans
