Hasdrubal, being precluded from passing the river, turned his course to the ocean; and they now advanced in disorder and in the manner of fugitives, so that the Roman legions were left considerably behind.

The cavalry and light-armed, attacking sometimes their rear, and sometimes their flank, harassed and delayed them; and as they were obliged to halt, in consequence of these frequent annoyances, and engaged sometimes the cavalry, at other times the skirmishers and the auxiliary infantry, the legions came up.
After this it was no longer a fight, but a butchering as of cattle, till the general himself, who was the first to run away, made his escape to the neighbouring hills with about six thousand men half armed; the rest were slain or made prisoners.

The Carthaginians hastily fortified an irregular camp on the highest eminence, and from thence they defended themselves without difficulty, the enemy failing in his attempt to get at them, from the difficulty of the ascent.

But a siege in a place bare and affording no means of subsistence, was hardly to be supported, even for a few days; the troops therefore deserted to the enemy.

At last the general himself, having procured some ships, for the sea was not at a great distance, left his army by night and effected his escape to Gades.
