Theodore I Laskaris, Emperor of Nicaea, ready to dismount and eventually behead Kaykushraw I, Sultan of Rum, during the battle of Antioch on the Meander between the Seljuk Turks and the army of the Empire of Nicaea (successor state to the Byzantine Empire after the Fourth Crusade).
"As the sources narrate, at this moment of victory, the Seljuk sultan sought out Laskaris, who was hard pressed by the attacking Turkish troops. Kaykhusraw charged his enemy and gave him a heavy blow on the head with a mace, so that the Nicaean emperor, dizzied, fell from his horse. Kaykhusraw was already giving orders to his retinue to carry Laskaris away, when the latter regained his composure and brought Kaykhusraw down by hacking at his mount’s rear legs. The sultan too fell on the ground and was beheaded, his head stuck on top of a lance and waved about, causing the Turks to panic and retreat."
