Scipio arrived in Spain about 210 B.C., and finding that a town, which the enemy had named New Carthage, was of great importance, he determined to attack it. Although the Carthaginians had three armies in Spain, each of their camps was at some distance from New Carthage. So confident, too, were the Punic generals of the strength of the town, that it was guarded by a garrison of only one thousand men. As for the inhabitants, they knew little of the use of arms, being for the most part fishermen and mechanics. Yet New Carthage was supremely important. She was the nearest port to Carthage, and it was at her harbour that reinforcements and stores from Africa were landed. Here, too, the Carthaginians kept their magazines, their money, and their Spanish hostages. The city was surrounded by high, strong walls, save at one place, where it was protected by an inland sea or lagoon. Here the walls were low and guarded less vigilantly, for the sea was believed to make the city secure from attack. But Scipio had been talking in his grave and pleasant way with the fishermen of New Carthage, and he had learned quite simply what he wished to know--that the sea was shallow enough at times to make it possible to reach the low and well-nigh unguarded wall. When Scipio, his plan determined, ordered his soldiers to march, they knew nothing of what their young leader meant to attempt. Only to Lælius, his most trusted friend, did he confide his scheme, bidding him take the Roman fleet to the harbour of New Carthage on a certain day. Lælius was to join in the assault upon the city; if it failed, he was to be ready to carry off the troops in his ships. Scipio’s orders were obeyed. The fleet reached the harbour at the same time that the Roman army encamped without the city walls. Mago, who was in command of the garrison, was surprised when he saw the Roman fleet in the harbour, the Roman army close to his gates. He at once ordered the walls to be manned, and about two thousand of the citizens to be armed. A party of soldiers then sallied out to drive off the enemy, the armed citizens joining in the attack. They were, however, beaten back by the Romans. In a panic the citizens crowded together in the narrow gateway, each trying to regain the safety of the streets. So foolish was their haste, that many of them were trampled underfoot and wounded, if not killed. The Roman soldiers all but succeeded in pushing their way into the city, along with the desperate citizens. They did not quite succeed, but they managed to fix the scaling ladders against the walls. This proved, however, of little use, for the ladders, they found, were too short for the height of the walls, while they suffered greatly from the arrows and missiles which fell in their midst. It was afternoon when the Romans withdrew, and the garrison believed that they were safe for another day. But a few hours later the besiegers again attacked the walls.
