From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
Most of the communities as far as the Ebro became dependent on Carthage and paid tribute to it. Hasdrubal skilfully by every means, even by intermarriages, attached the chiefs to the interests of Carthage. Thus Carthage acquired in Spain a rich market for its commerce and manufactures; and not only did the revenues of the province sustain the army, but there remained a balance to be remitted to Carthage and reserved for future use.
The province formed and at the same time trained the army; regular levies took place in the territory subject to Carthage; the prisoners of war were introduced into the Carthaginian corps. Contingents and mercenaries, as many as were desired, were supplied by the dependent communities.
During his long life of warfare the soldier found in the camp a second home, and found a substitute for patriotism in fidelity to his standard and enthusiastic attachment to his great leaders. Constant conflicts with the brave Iberians and Celts created a serviceable infantry, to co-operate with the excellent Numidian cavalry.
