The Roman History · Amm. 23.3.5

Indignant at such atrocity and at such an insult, he immediately (as indeed he had previously contemplated) put thirty thousand chosen men under the orders of Procopius, who has been already mentioned, uniting with him in this command Count Sebastian, formerly Duke of Egypt; and he ordered them to act on this side of the Tigris, observing everything vigilantly, so that no danger might arise on any side where it was not expected, for such things had frequently happened. He charged them further, if it could be done, to join King Arsaces; and march with him suddenly through Corduena and Moxoëne, ravaging Chiliocomus, a very fertile district of Media, and other places; and then to rejoin him while still in Assyria, in order to assist him as he might require.
