Res Gestae

And while there was no one to withstand them, with eager haste they repaired a fortress which Trajan had built in the territory of the Alamanni and wished to be called by his name, and which had of late been very forcibly assaulted. There a temporary garrison was established and provisions were brought thither from the heart of the savages’ country.

When the enemy saw these preparations rapidly made for their destruction, they quickly assembled, dreading the completion of the work, and with prayers and extreme abasement sent envoys and sued for peace. And Caesar granted this for the space of ten months, since it was recommended by every kind of consideration, and he could allege very many plausible reasons for it; for doubtless he appreciated with his keen mind that the stronghold which, beyond any possible hope, he had seized without opposition, ought to be fortified with artillery on the walls and powerful appliances of war.

Confiding in this peace, three very savage kings finally appeared, though still somewhat apprehensive since they were of the number of those who had sent aid to the vanquished

In this memorable war, which in fact deserves to be compared with those against the Carthaginians and the Teutons, but was achieved with very slight losses to the Roman commonwealth, Caesar took pride as a fortunate and successful general. And one might well believe his detractors, who pretended that he had acted so courageously on all occasions because he chose rather to perish fighting gloriously than to be put to death like a condemned criminal (as he expected), after the manner of his brother Gallus-had he not with equal resolution, even after Constantius’ death, increased his renown by marvellous exploits.
