Royal Damsel, Jack's Distress Pirates of Caribbean 2 Guide
Last update: 11 May 2016
After repelling the first waves of attackers cross the newly created crack in the wall to take on some more pirates. The fight will go on until you get rid of all four ladders up which new foes are coming.
After another wall explodes, run to the right, to the bookcase behind which is another Map Piece.
Next go down the stairs where you'll find Pintel, the second boss. Elizabeth's axes are the best measure here. After you reduce him to 50% health he'll flee and you'll have a minute or so to get out of the house, killing pirates on the way out and passing another minigame by pressing the correct sequence of buttons.
Despite the looks of it, you have quite a bit of time for this.
