Quick recap
Right after Stephen's wedding, Jack takes HMS Worcester on the Toulon blockade. The ship is worn out and sent for a refit, so Jack moves to the Surprise for a mission to the Ionian coast, with Stephen and Professor Graham aboard. Jack backs Sciahan Bey, who holds Kutali and its Christian population. A false rumor spread by Ali Pasha pushes Mustapha to seize the British gun transports. The Surprise intercepts Mustapha's two ships, Torgud and Kitabi. Jack boards Kitabi, which surrenders, then crosses to Torgud and reaches the wounded Mustapha himself. The Surprise pulls away before Torgud sinks.
