The order of battle on each side was as follows. The Roman cavalry were posted on the wings in order to protect the infantry. At this point there is a lacuna in the text. Hannibal ranged his elephants opposite the Roman horse and his foot-soldiers against the legions, and he ordered his own cavalry to remain quiet behind the elephants until he should give the signal. When battle was joined the horses of the Romans, terrified by the sight and smell of the elephants, broke and fled. The foot-soldiers, although suffering much and weakened by cold, wet clothes, and want of sleep, nevertheless boldly attacked these beasts, wounded them, and cut the hamstrings of some, and were already pushing back the enemy's infantry. Hannibal, observing this, gave the signal to his horse to attack the Roman flank. The Roman horse having been just dispersed by fear of the elephants, the foot-soldiers were left without protection, and were now in difficulties. Fearing lest they should be surrounded, they everywhere broke in flight to their own camp. Many foot-soldiers were cut off by the enemy's horse and many perished in the swift stream, for the river was now swollen with melting snow so that they could not wade, on account of its depth, nor could they swim, on account of the weight of their armor. Scipio, who followed trying to rally them, was wounded and almost killed, and was with difficulty rescued and carried to Cremona. There was a small arsenal near Placentia which Hannibal laid siege to, where he lost 400 men and was himself wounded. And now they all went into winter quarters, Scipio in Cremona and Placentia, and Hannibal on the Po. When the Romans in the city learned of this third defeat on the Po (for they had in fact been beaten by the Boii before Hannibal arrived), they levied a new army of their own citizens which, with those already on the Po, amounted to thirteen legions, and they called for double that number from the allies. At this time the legion consisted of 5000 foot and 300 horse. Some of these they sent to Spain, some to Sardinia (for they were at war there also), and some to Sicily. The greater part were despatched against Hannibal under Cn. Servilius and Gaius Flaminius, who had succeeded Scipio and Sempronius as consuls. Servilius hastened to the Po where he received the command from Scipio. The latter, having been chosen proconsul, sailed for Spain. Flaminius, with 30,000 foot and 3000 horse, guarded Italy within the Apennines, which alone can be properly called Italy. The Apennines extend from the centre of the Alpine range to the sea. The country on the right-hand side of the Apennines is Italy proper. The other side, extending to the Adriatic, is now called Italy also, just as Etruria is now called Italy, but is inhabited by people of Greek descent, along the Adriatic shore, the remainder being occupied by Gauls, the same people who at an early period attacked and burned Rome. When Camillus drove them out and pursued them to the Apennines, Y.R. 537 it is my opinion that they crossed over these mountains B.C. 217 and made a settlement near the Adriatic instead of their former abode. Hence this part of the country is still called Gallic Italy.
