Destruction of the pirate fleet

A small pirate fleet consisting of at least 3 tall ships and 1 slightly smaller ship was on the way to Shipwreck Island in order to join the Brethren Court meeting, when the Flying Dutchman submerged shortly behind them and immediately opened fire. The pirates were surprised by this attack and before they could repeat fire, the Flying Dutchman sailed between them firing in all directions. The Pirate ships were completely destroyed and all persons aboard were killed. However, this made Lord Cutler Beckett angry since he wanted prisoners in order to question them, so he ordered the transfer of the heart of Davy Jones to the Flying Dutchman and stationed a large group of [[East India Trading Company Marines aboard the ship.
