They waited till the whole army was once more united in Libya, and then endeavoured to curtail the pay promised to the men.
Of course a mutiny broke out among the troops, and the hesitating and cowardly demeanour of the authorities showed the mutineers what they might dare.

Most of them were natives of the districts ruled by, or dependent on, Carthage; they knew the feelings which had been provoked throughout these districts by the slaughter decreed by the government after the expedition of Regulus( 1) and by the fearful pressure of taxation, and they knew also the character of their government, which never kept faith and never pardoned; they were well aware of what awaited them, should they disperse to their homes with pay exacted by mutiny.

The Carthaginians had for long been digging the mine, and they now themselves supplied the men who could not but explode it.
Like wildfire the revolution spread from garrison to garrison, from village to village; the Libyan women contributed their ornaments to pay the wages of the mercenaries; a number of Carthaginian citizens, amongst whom were some of the most distinguished officers of the Sicilian army, became the victims of the infuriated multitude; Carthage was already besieged on two sides, and the Carthaginian army marching out of the city was totally routed in consequence of the blundering of its unskilful leader.
When the Romans thus saw their hated and still dreaded foe involved in a greater danger than any ever brought on that foe by the Roman wars, they began more and more to regret the conclusion of the peace of 513 -- which, if it was not in reality precipitate, now at least appeared so to all--and to forget how exhausted at that time their own state had been and how powerful had then been the standing of their Carthaginian rival.

Shame indeed forbade their entering into communication openly with the Carthaginian rebels; in fact, they gave an exceptional permission to the Carthaginians to levy recruits for this war in Italy, and prohibited Italian mariners from dealing with the Libyans.

But it may be doubted whether the government of Rome was very earnest in these acts of friendly alliance; for, in spite of them, the dealings between the African insurgents and the Roman mariners continued, and when Hamilcar, whom the extremity of the peril had recalled to the command of the Carthaginian army, seized and imprisoned a number of Italian captains concerned in these dealings, the senate interceded for them with the Carthaginian government and procured their release.
