No man could then have foreseen how long and severe the war was going to be. It lasted three and twenty years (264-241); and at the beginning all the advantage seemed to be on the Carthaginian side. In the first place Carthage had the strongest navy in the world. The Carthaginian army was much the larger, though it was composed of paid soldiers of foreign race. There was no outstanding leader on the Roman side equal to Hamilcar, who commanded the Carthaginians in its later stages. When the war began the Romans had no fleet. They had never had more than a few transport vessels: no fighting ships. They did not know how they were constructed. This did not daunt them, however. A Carthaginian man-of-war was driven ashore. Roman carpenters and shipwrights at once set to work, studying how it was put together, and thinking out devices by which it could be improved. While the shipwrights were busy the men practised rowing on dry land. The most famous improvement invented by the Romans was the ‘crow’. This was an attachment to the prow, worked by a pulley, consisting of a long pole with a sharp and strong curved iron spike at the end. As soon as an enemy ship came within range this pole was swung round so that the spike caught the vessel and held it in an iron grip. A bridge was fastened to the pole: the soldiers ran along and boarded, forcing a hand-to-hand fight. To this the Carthaginian sailors were not used. They were better navigators than the Romans, but not such good fighters. In hand-to-hand encounters the Romans got the best of it. But they did not know so much of wind and weather, and again and again the storms made havoc with them. Four great fleets were destroyed or captured in the first sixteen years of the war, which lasted for twenty-three. In the year 249 Claudius the Consul lost 93 vessels at a stroke in the disastrous battle of Drepana and killed himself rather than live on under the disgrace. Later in the same year another great fleet was dashed to pieces in a storm. [Illustration: PICTURES FROM POMPEII--]
