On 25 June, the Ottoman army crossed the Isthmus of Corinth and entered the Morea. The citadel of Acrocorinth, which controlled the passage to the peninsula, surrendered after a brief siege, on terms of safe passage for the garrison and the civilians. However, some Janissaries, eager for plunder, disobeyed Damat Ali's orders and entered the citadel. A large part of the garrison, including the "provveditore" Giacomo Minoto, and most of the civilians were massacred or sold to slavery. Only 180 Venetians were saved and transported to Corfu. These tragic events later inspired Lord Byron's poem "The Siege of Corinth".
