Cuius atrocitate mali perculsus, ilico (ut ante cogitaverat) triginta milia lectorum militum eidem commisit Procopio, iuncto ad parilem potestatem Sebastiano comite ex duce Aegypti, eisdemque praecepit, ut intra Tigridem interim agerent, vigilanter omnia servaturi, nequid inopinum ex incauto latere oreretur, qualia multa saepe didicerat evenisse, mandabatque eis ut (si fieri potius posset), regi sociarentur Arsaci, cumque eo per Corduenam et Moxoenam, Chiliocomo uberi Mediae tractu, partibusque aliis praestricto cursu vastatis, apud Assyrios adhuc agenti sibi concurrerent, necessitatum articulis adfuturi.
Startled by this cruel disaster, Julian (as he had previously planned) instantly put 30,000 picked men under the command of the aforesaid Procopius, and joined to him with equal powers Sebastianus, formerly a military commander in Egypt, and now a count, with orders to keep for the present on this side of the Tigris and to watch carefully everywhere and see that nothing unexpected should happen on the unprotected side, such as he had heard had often occurred. And he gave the order that (if it could be done to greater advantage) they should join King Arsaces, march with him through Corduene and Moxone, lay waste in passing by Chiliocomum, a fruitful region of Media, and other places, and meet him while he was still in Assyria, so as to aid him in cases of necessity.
