Bryennios the ethnarches became strategos of Cappadocia. After joining the rebel eastern generals, he crossed to the east with the patrikios Ioannes Opsaras, sent by Michael VI to pay the troops and administer the military budget: he ordered Opsaras to raise the salaries of his army. When he refused, saying that these were not the emperors orders, Bryennios grew angry, punched him, took him by the beard, threw him to the ground, tied him up, kept him in his tent, and distributed the gold as he wished. Lykanthes was camped near Bryennios in Anatolikon. Though unaware of the generals plot, he considered the treatment of Opsaras an act of rebellion. He attacked Bryennios in his tent with the two tagmata of Anatolikon, proclaiming the emperor Michael VI, imprisoned Bryennios and released Opsaras. He then handed Bryennios to Opsaras, and distributed the army salaries as ordered. Opsaras immediately took vengeance on Bryennios by blinding him, and sent him to Michael VI with a report of revolutionary behaviour
