A few days later the Carthaginian army were astonished by the issue of an order that the whole were to be in readiness to march upon the following day.

The greatest excitement arose when the news got abroad.
None knew against whom hostilities were to be directed.

No one had heard aught of the arrival of messengers announcing fresh insurrection among the recently conquered tribes, and all sorts of surmises were indulged in as to the foe against whom this great force, the largest which had ever been collected by Carthage, were about to get in motion.
The army now gathered around Carthagena amounted, indeed, to a hundred and fifty thousand men, and much surprise had for some time existed at the continual arrival of reinforcements from home, and at the large number of troops which had during the winter been raised and disciplined from among the friendly tribes.
Simultaneously with the issue of the order long lines of wagons, laden with military stores, began to pour out from the arsenals, and all day long a procession of carts moved across the bridge over the canal in the isthmus to the mainland.

The tents were struck at daylight, the baggage loaded up into the wagons told off to accompany the various bodies of soldiers, and the troops formed up in military order.
When Hannibal rode on to the ground, surrounded by his principal officers, a shout of welcome rose from the army; and he proceeded to make a close inspection of the whole force.

The officers then placed themselves at the head of their respective commands, the trumpets gave the signal, and the army set out on a march, as to whose direction and distance few present had any idea, and from which few, indeed, were ever destined to return.
There was no longer any occasion for secrecy as to the object of the expedition.
