The rescue attempt goes awry and Barbossa maroons Jack and Elizabeth on the same island upon which he had stranded Sparrow before. Elizabeth creates a signal fire from rum barrels and they are rescued by the Royal Navy. Sparrow cuts a deal with Commodore James Norrington to lead Norrington to "Black Pearl". Norrington refuses until Elizabeth, desperate to save Will, spontaneously accepts Norrington's earlier marriage proposal. Right before the film's climactic battle with the pirates at Isla de Muerta, Sparrow swipes a cursed coin from the treasure chest, making himself immortal and capable of dueling Barbossa. He shoots his nemesis with the pistol he has carried for ten years just as Will breaks the curse, killing Barbossa. Despite having assisted the Navy, Sparrow is sentenced to hang.
