The fairest regions of Spain, the southern and eastern coasts, became Phoenician provinces. Towns were founded; above all, "Spanish Carthage" (Cartagena) was established by Hasdrubal on the only good harbour along the south coast, containing the splendid "royal castle" of its founder. Agriculture flourished, and, still more, mining in consequence of the fortunate discovery of the silver-mines of Cartagena, which a century afterwards had a yearly produce of more than 360,000 pounds (36,000,000 sesterces). 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. The Carthaginian Government and the Barcides So far as Carthage was concerned, the Barcides were allowed to go on. Since the citizens were not asked for regular contributions, but on the contrary some benefit accrued to them and commerce recovered in Spain what it had lost in Sicily and Sardinia, the Spanish war and the Spanish army with its brilliant victories and important successes soon became so popular that it was even possible in particular emergencies, such as after Hamilcar's fall, to effect the despatch of considerable reinforcements of African troops to Spain; and the governing party, whether well or ill affected, had to maintain silence, or at any rate to content themselves with complaining to each other or to their friends in Rome regarding the demagogic officers and the mob.
