enemy every opportunity of making the best of the advantage. Scipio had put some light-armed troops in the van. They seemed to have been of the poorest quality, for they fled at the first impact of the two armies. The regular cavalry of the Romans showed to better advantage. They held their own for some time against their assailants, also a force of regular cavalry. But they were at a great disadvantage. The fugitives from the front had thrown their lines into disorder. These it was impossible to keep firm when those panic-stricken creatures were trying to find their way through them. Then there happened a great misfortune. Scipio was so seriously wounded that he had to give up the command. According to the most generally received account, he was saved from capture by the valour of his son, then a lad of eighteen. We shall hear of him again, for he became in later years the great hero of the war, Scipio Africanus the elder. Some of the Roman cavalry made a determined stand round their wounded chief and contrived to carry him off the field. But the battle was lost. The defeat, however, was not so complete that the Roman camp was in any danger. Hannibal, who was still hampered by his scanty numbers, was content to rest on the field of battle. That night the Romans hurriedly retreated to Placentia, hoping to find their bridge unbroken. They had actually reached their destination before Hannibal became aware of their departure. He was in time enough, however, to capture some six hundred stragglers whom he found lingering on the left bank of the Po. A great raft had been constructed for the passage of the river, and they were at work in loosing it. Hannibal came upon them while they were so employed. He captured the men, but the raft, which it would have been a great advantage to secure, floated down-stream. Two days were spent in looking for a practicable ford. Before this could be found the Roman army had recovered its order and confidence. It suffered, however, a most damaging blow within the next few days. A body of Gallic auxiliaries, two thousand infantry, and two hundred cavalry, deserted to Hannibal, cutting down the sentries at the camp gate. The Carthaginian general gave them a hearty welcome, and held out to them great promises of advancement and reward. For the present he sent them to their homes. The best service, in his judgment, that they could do was to spread abroad the report of his generosity and of the Roman defeat.
