As soon as day broke the rest of the army got into motion and proceeded up the pass.

The natives were now seen approaching in great numbers, but they halted in dismay on seeing that the Carthaginians had already gained possession of the strong places.
The road by which the column was ascending wound along the face of a precipice, and was so narrow that it was with difficulty that the horses, snorting with fright, could be persuaded to proceed.

The natives, seeing the confusion which the fright of the animals created in the column, at once took to the mountains, climbing up rugged precipices which appeared to the Carthaginians absolutely inaccessible, and presently made their appearance far up on the mountain side above the column.
Here, sending up the most piercing yells, they began to roll rocks and stones down upon the column.

The confusion below became terrible.

The horses, alarmed by the strange wild cries, echoed and re-echoed a score of times among the mountains, and struck by the falling stones, plunged and struggled wildly to escape.
