The subsequent years witnessed the gradual extinction of Byzantine rule in Asia Minor, as Orhan of the Ottoman Turks, who had already defeated Andronikos III at Pelekanos in 1329, took Nicaea in 1331 and Nicomedia in 1337.

After that, only Philadelpheia and a handful of ports remained under Byzantine control in Asia Minor.

Earlier Andronikos III had effected the recovery of the islands of Lesbos and Chios from Martino Zaccaria in 1329 ( although the island remained under Benedetto III Zaccaria until 1330 ) and of Phocaea in 1334 from the last Genoese governor Domenico Cattaneo.

However, this did little to stem the Ottoman advance in Asia Minor.
