Following their conquest of Rhodes, which they made their base of operations,[1] the Knights Hospitaller quickly assumed military action in the waters of the Aegean Sea.
In retaliation, the Genoese gave 50,000 gold florins to Mesud, Emir of Menteshe, to attack the Knights.
[2][3] Masud seized several Rhodian merchants in the mainland, and Genoese and Turkish galleys began attacking Hospitaller shipping.
A contemporary letter by an Aragonese ambassador to the Council of Vienne, however, mentions 1,500 Turks and 75 Knights killed.
[4][5] In the aftermath of the battle, the Hospitallers captured Kos and castles on the mainland, probably the coast of Menteshe.
