Et postquam castello aut coniunctis tumulis non degrediebantur, obsidium coepit per praesidia, quae opportune iam muniebat; dein fossam loricamque contexens quattuor milia passuum ambitu amplexus est; tum paulatim, ut aquam pabulumque eriperet, contrahere claustra artaque circumdare; et struebatur agger, unde saxa hastae ignes propinquum iam in hostem iacerentur.
