to be composed of a single nationality and some armies were very mixed. Usually an effort was made not to rely too heavily on the peoples indigenous to the theatre of operations for fear of defection or desertion. Before his Italian expedition Hannibal sent a large contingent of Spanish troops to Africa, replacing them with units raised there. The Carthaginian high command provided the sole unifying force in each army. 11
It is conventional to describe Punic armies as consisting of mercenaries, but this is a gross oversimplification, since these forces included soldiers raised in many different ways with a great variety of different motivations. Some contingents were not hired, but provided by allied kingdoms or states as part of their treaty obligations. This always seems to have been the case with the Numidian kingdoms, whose royal families enjoyed a fairly close relationship with the Carthaginian noble families, bonds that were sometimes strengthened by marriage alliances. Numidian contingents were usually led by their own princes. Similarly many of the tribes in Spain and Gaul were formally allied to Carthage and fielded contingents identical to their own tribal armies and commanded by their own chieftains. Again, there is some indication of Punic leaders forming strong connections with the native aristocracy, perhaps allowing them to exploit traditional patterns of loyalty. Hasdrubal certainly married a Spanish princess and it is possible that Hannibal also did so. It is clear that the Spanish tribes' loyalty focused on the Barcid family rather than the distant Carthage. Later, the tribes would similarly adhere to the Scipiones, rather than Rome, rebelling when it was rumoured that Scipio Africanus had left Spain. 12
We do not know precisely how the Libyan units were raised. Some troops were probably provided by allied cities in a similar manner to the Numidians. Others may well have been formed by peasants conscripted from the great Carthaginian estates. This area was later to prove a very fertile recruiting area in the Roman Empire. Even the troops clearly hired as mercenaries were not all recruited in the same manner. In some cases these men were hired as a group, a leader or chieftain offering his own and his warband's services for hire. The leader received payment for his services and then supported, and distributed rewards amongst, his followers much as any chieftain would do. In the tribal societies of Europe there was a strong tradition of warriors seeking service with the leaders who could support and give them wealth and glory, for a martial reputation was highly valued wherever it was attained. The bond between such a chieftain and his followers was intensely personal. They fought for him and would just as happily fight with or against Carthage as their leader chose. We hear of one group of Gauls led by a chieftain who served several masters in succession and proved of dubious loyalty to each of them. The loyalty of such soldiers must have been significantly different from that of men who had been directly recruited and were directly paid by their Carthaginian leaders. Presumably some units in the army, especially those which included Roman and Italian deserters and escaped slaves, were of mixed nationality. 13
Our sources rarely refer to the organization of the various contingents in Carthaginian armies, simply telling us where each nationality stood, so it is unclear whether any troops were organized into units of a set size. Livy makes reference to a unit of 500 Numidian cavalry, but this might simply have been one contingent and there is no indication that these horsemen fought in regular units. Another passage mentions 500 Libyan infantry at Saguntum in 218 and we also hear of 2,000 Gauls divided into three bands or units at the capture of Tarentum in 212, although it is uncertain whether these were permanent or temporary arrangements. Normally Gallic and sometimes Spanish troops fought in tribal
