The Roman History · Amm. 17.1.12

And the Cæsar, now that he had fully matured and secured the success of all his designs, taking into consideration all probabilities, granted them a truce for ten months. In reality he was especially influenced by this prudent consideration, that the camp which he had thus occupied without hindrance, in a way that could hardly have been hoped for, required, nevertheless, to be fortified with mural engines and other adequate equipments.
