From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
After this day folly alone could counsel a continuance of the war on the part of Carthage. On the other hand it was in the power of the Roman general immediately to begin the siege of the capital, which was neither protected nor provisioned, and, unless unforeseen accidents should intervene, now to subject Carthage to the fate which Hannibal had wished to bring upon Rome.
Scipio did not do so; he granted peace (553), but no longer upon the former terms. Besides the concessions which had already in the last negotiations been demanded in favour of Rome and of Massinissa, an annual contribution of 200 talents (48,000 pounds) was imposed for fifty years on the Carthaginians; and they had to bind themselves that they would not wage war against Rome or its allies or indeed beyond the bounds of Africa at all, and that in Africa they would not wage war beyond their own territory without having sought the permission of Rome--the practical effect of which was that Carthage became tributary and lost her political independence. It even appears that the Carthaginians were bound in certain cases to furnish ships of war to the Roman fleet.
