Please note that Mommsen uses the AUC chronology (Ab Urbe Condita), i.e. from the founding of the City of Rome. You can use this reference table to have the B.C. dates
The demands made by Regulus, and his very
near approach to the obtaining of what he asked, could only be
forgotten by those who were willing to forget; and if Rome should now
renew from Lilybaeum the enterprise which she had undertaken with so
great success from Italy, Carthage would undoubtedly fall, unless the
perversity of the enemy or some special piece of good fortune should
intervene to save it No doubt they had peace for the present; but the
ratification of that peace had hung on a thread, and they knew what
public opinion in Rome thought of the terms on which it was concluded.
It might be that Rome was not yet meditating the conquest of Africa
and was as yet content with Italy; but if the existence of the
Carthaginian state depended on that contentment, the prospect was but
a sorry one; and where was the security that the Romans might not find
it even convenient for their Italian policy to extirpate rather than
reduce to subjection their African neighbour?
