The First Punic War is a record of a dismal wastage of human life and of strategic ineptitude. Briefly the Roman mistakes may be summed up as follows. First, the popular assembly which accepted the alliance with Messana seems to have failed to realize that the Carthaginians were bound to try to eject them from Sicily; to fight Carthage Rome needed a navy; she had none of her own and even in the treaty with Hiero asked for no naval assistance. Secondly, Rome made her struggle in Sicily much harder because she alienated all the Greeks by her ungenerous treaty with Hiero and by the massacre of non-combatants at Agrigentum. Thirdly, she was very slow to realize that the only way to get the Carthaginians out of Sicily was to strike at Africa; Agathocles in 310 had already pointed the way. Fourthly, Regulus failed to enlist willing Numidians in his cavalry, although a strong cavalry was essential on the plains of Africa. Fifthly, Regulus was left with far too small a force. Lastly, Rome continued to change the command and appoint inexperienced men, though few were quite so incompetent as Regulus who, when faced by the elephants and phalanx of Xanthippus, massed his legionaries, thus making them an easy prey to the Carthaginian battering ram.
