The actual pretext for the war is too dramatic to be passed over. The mutinous mercenaries of Agathocles (317-289 B.C.) had taken possession of the city of Messana. They were attacked by Hiero of Syracuse with such success that they appealed alternately to the Carthaginians and Romans for help. The Carthaginians came to the rescue first and put a garrison in the citadel of Messana. But the commander was so foolish as to enter into negotiations with the Roman legate, who had crossed the straits of Messana with a small body of troops, and in the course of them was taken prisoner--through his own perfidious treachery it must be acknowledged. Thus the key of Sicily fell into Roman hands, and war was declared. The history of the next hundred and twenty years is wholly occupied with the great struggle between these two cities, till at length, in 146 B.C., Carthage was laid level with the ground. Thus the state of Rome, which had won for itself a leading position in Italy in the Wars of Liberation waged with the Etruscans and Sabellians, and had then been forced by the Samnites into a contest for the sovereignty of Italy, found itself driven almost involuntarily into a decisive struggle for dominion over all the coasts of the Mediterranean. The perseverance with which Rome strove towards the goal of ever higher ambitions commands our admiration, and we admire no less the government of the many-headed senate which kept one constant aim in view and consistently pursued it; which, moreover, steered the ship of state safely through all dangers, when the incompetency of its annually elected chief magistrates resulted in the gravest catastrophes. There lay the weakness of the Roman commonwealth. How could Roman consuls, elected annually by the people, usually on political grounds, acquire the capacity to command armies, to master the art of strategy, or to lead troops and fleets in regions to which they themselves were strangers? To the ill effects of this preposterous system Rome owed the severe reverses of the First Punic War (264-241 B.C.) and the beginning of the Second. The situation began to improve when two capable leaders, Marcellus and the Scipios, were left in command for several consecutive years. Nevertheless, the Roman armies were frequently led by gallant and judicious men, and won some lasting successes even in the First Punic War, one of the most protracted and sanguinary wars of ancient times.
