Finally both the Roman wings, being hard pressed in front by the elephants, and on both flanks by the light-armed troops of the enemy, gave way, and in their flight were forced upon the river behind them. After this, while the centre of the Roman rear was losing heavily, and suffering severely from the attack of the Numidian ambuscade, their front, thus driven to bay, defeated the Celts and a division of Africans, and, after killing a large number of them, succeeded in cutting their way through the Carthaginian line. Then seeing that their wings had been forced off their ground, they gave up all hope of relieving them or getting back to their camp, partly because of the number of the enemy's cavalry, and partly because they were hindered by the river and the pelting storm of rain which was pouring down upon their heads.

Of the rest of the army the greater number were killed by the elephants and cavalry on the bank of the Trebia; while those of the infantry who escaped, and the greater part of the cavalry, managed to rejoin the ten thousand mentioned above, and arrived with them at Placentia. Meanwhile the Carthaginian army pursued the enemy as far as the Trebia; but being prevented by the storm from going farther, returned to their camp. They regarded the result of the battle with great exultation, as a complete success; for the loss of the Iberians and Africans had been light, the heaviest having fallen on the Celts. But from the rain and the snow which followed it, they suffered so severely, that all the elephants except one died, and a large number of men and horses perished from the cold.
