The Battle of the Cyzicus was fought in October 1303 between the Catalan Company of the East under Roger de Flor, acting as mercenaries on behalf of the Byzantine Empire, and the Karasid Turks under Karesi Bey. It was the first of several engagements between the two sides during the Catalan Company's Anatolian Campaign. The result was a crushing Catalan victory. The almogavars of the Catalan Company made a surprise attack on the Oghuz Turkish camp located at the Cape Artake, killing about 3000 cavalry and 10,000 infantry and capturing many women and children.
