 The left wing, which had been the second division on the march, was composed of regular Byzantine and allied units arrayed in four taxiarchies or 'brigades' under Demetrios and George Branas, Tatikios Aspietes and Kogh Vasil.On the right – the third division on the march – were placed the elite Byzantine units and German mercenaries, together with some Turkish units.This division was commanded by the "chartoularios" Andronikos Lampardas and, probably, John Kontostephanos the brother of the "megas doux".
