With the Islamic army already set up in Yarmouk, Vahan hardly had any choice, but his reaction was relatively vague. Relations between other Byzantine commanders are also full of tension. Could I be drinking anymore coffee mug. There was a battle for power that broke out between Trithurios and Vahan, Jarajis, and Qanateer. Jabalah-commander of Arab Christianity silently refused to speak out his knowledge of the terrain at Yarmouk despite the damage that Byzantine would suffer. A lack of trust existed between the Byzantines, Armenians and Arabs. The long-standing religious disputes between the Monophysite and Chalcedonian factions (the factions in the Orthodox Christian Church?) For small reasons have certainly created hidden tension.
Consequently, these hatreds weakened coordination and the battle plan became irrelevant, which is one of the reasons for the Byzantine catastrophic failure. According to a well-described source of the battle, the Muslim and Byzantine fighting squad is divided into four sections: the left wing, the left-center wing, the left-center center and the right wing. Note that the Muslim descriptions of the Byzantine fighting formation are exactly the same as the other side, ie: the Muslim right wing facing the Byzantine left wing etc. and so on (see image below). painting)
