Roger Crowley reconstructs the fifty-three-day siege of Constantinople, detailing the final collapse of the Byzantine Empire under the assault of Sultan Mehmed II. The narrative focuses on the technical and tactical imbalances of the conflict, specifically the Ottoman use of massive Hungarian-designed cannons to breach the ancient Theodosian Walls. Crowley tracks the individual maneuvers of the Christian defenders led by Constantine XI and the Genoese soldier Giovanni Giustiniani as they faced a numerically superior force. The account concludes with the city’s violent transition from a Christian capital to the seat of the Ottoman Empire.
