In late 582, however, serving as John's hypostrategos (deputy commander), through his inaction (allegedly due to jealousy towards John), the Byzantines were defeated in battle.
Namun pada akhir tahun 582 ia bekerja sebagai hypostrategos Ioannis (wakil komandan), melalui kelambanannya (diduga karena kecemburuan terhadap Ioannis), Bizantium dikalahkan dalam pertempuran.
