The Arabs were driven from the field. The Byzantine Extra Heavy Cavalry (EHC) rallied from their pursuit of the broken infantry units unmolested, and used their ability to shoot (bows and darts) and charge to inflict just enough casualties to break the Arab Heavy Cavalry (HC).
This bad photo’s perspective is from East to West representing (in a crude manner) the penultimate stage of the battle. The Persians EHC are at the bottom of the shot; the Byzantine Super Heavy Cavalry (SHC) engaged in the center, with two Byzantine EHC units to the North. One is engaged and the other waiting to wheel into a flank attack .
The Arab HC shown to the top of the preceding photo is now flanked, with the center Arab HC broken and pursued by the Byzantine SHC. The Arab Commander-In-Chief, along with his Bodyguard is waiting to aide one of his units, while the poor bastard manning the bolt thrower is standing slack jawed, immobilized by the spectacle.
The former Arab HC unit will break and outdistance its pursuers, while the Persian EHC will fight their Byzantine counterparts to a standstill.
At this point the Arab Commander-In-Chief ordered a general withdrawal, saving himself , his bodyguard and his cavalry for another battle.
Will post up final thoughts, observations, and other inane musings in a follow up before setting up Husaria.
