[6] Valens sent a large army to Armenia under the command of generals Traianus and Vadomarius, but with orders to engage only in defensive actions, hoping to maintain the peace with Persia.

[6] The Armenians also assembled their army under the command of sparapet (general-in-chief) Mushegh Mamikonian and convened with the Romans near the settlement of Bagavan, in the district of Bagrevand, at the foot of Mount Npat, near the source of the Arsanias River.

[10] According to Faustus, King Pap did not take part in the battle and observed from Mount Npat together with Patriach Nerses at the request of the Roman generals.

[11] Faustus tells of another great battle at Gandzak in Adurbadagan where the Armenians and Romans routed the Persians again, this time with Shapur there in person.

[13] As a result of these victories, Mushegh is said to have reconquered many lost Armenian territories and forced the nobles who had revolted against the Arsacid monarchy to submit to Pap's authority.
