After a war council on 13 June, 15,000 Janissaries under Kara Mustafa Pasha were sent to capture Lepanto, while the main body of the army under Yusuf Pasha and the Agha of the Janissaries moved onto the Isthmus of Corinth and the two fortresses of Acrocorinth and Nauplia, the main Venetian strongholds in the Morea. In the meantime, the Ottoman Fleet, numbering 80 warships under Canum Hoca, had captured the last Venetian possessions in the Aegean, the islands of Tinos and Aigina.
