17. The fields of operation of the consuls had already been named: they were now commanded to draw lots for them. Cornelius obtained Spain, Sempronius Africa with Sicily. [2] Six legions were voted for that year, with such allied contingents as the consuls themselves should approve and as large a fleet as could be got ready. There were enrolled four and twenty thousand Roman foot-soldiers and eighteen hundred horsemen, and of the allies forty thousand foot-soldiers and four thousand four hundred horsemen. [3] Of ships there were launched two hundred and twenty quinqueremes, and twenty swift cruisers. [4] The question was then laid before the people whether it were their will and pleasure that war be declared against the people of Carthage; and on their voting in the affirmative a supplication was held throughout the City and the gods were besought to grant a fair and prosperous outcome to the war which the Roman People had decreed.

[5] The forces were divided between the consuls as follows: Sempronius received two legions —each numbering four thousand foot and three hundred horse —sixteen thousand foot of the allies, and eighteen hundred horse, together with a hundred and sixty warships and twelve swift cruisers. [6] With these forces for land and sea Tiberius Sempronius was dispatched to Sicily, that he might cross by that way into Africa, if the other consul were able to keep the Phoenicians out of Italy. [7] Cornelius was given fewer troops, since Lucius Manlius, the praetor, [p. 49]was also being sent into Gaul with a not¹ inconsiderable army; [8] and of ships, in particular, he received a smaller number, namely, sixty quinqueremes, for they did not suppose that the enemy would come by sea or use that kind of warfare. He had two Roman legions with their proper complement of horse, and fourteen thousand infantry of the allies, with sixteen hundred horse. [9] The province of Gaul received two Roman legions and ten thousand foot of the allies, with a thousand allied and six hundred Roman horse. These troops were designed for the same service —the Punic War.
