The Venetians, with assistance of the Greeks, conquered the rest of the Peloponnese and then besieged Athens. During the siege of Athens, the Ottomans used the Parthenon as an ammunition depot. When artillery fire from the Venetians struck the depot, the resulting explosion damaged large portions of the Parthenon. The desperate Ottomans freed Limberakis and gave him the title "His Highness, the Ruler of Mani". Limberakis immediately launched several raids into Venetian-held territories of the Peloponnese. However, when the Ottomans attempted to poison Limberakis, he defected to the Venetian side. The Venetians made Limberakis a Knight of St. Mark and recognized him as ruler of Roumeli. Limberakis first attacked the city of Arta, when the Ottomans destroyed his estates at Karpenisi. He captured and plundered the city before going back to Mani. The Arteans sent a committee to Venice and reported everything to the Doge. Ultimately, Limberakis moved to Italy where he died fourteen years later.
