Where There' Fire, There's Blacksmoke Pirates of Caribbean 2 Guide
Last update: 11 May 2016
Immediately after the animation ends, run along the coast. After a brief fight with the pirates the dock will blow up and you'll need Elizabeth's axes to knock down the planks to clear your way. . Before you run onward, set the buoy closer to the camera on fire - a similar procedure will be required on the other four to obtain a Map Piece.
While running on the other side watch out for holes in the jetty and pirate marksmen shooting from afar, until you reach the estuary with the barrel of grog. On either side of it is a buoy. The fourth is in another estuary and the last one is at the end of the main dock on the right side.
After you set it aflame, knock over another set of planks with Elizabeth's help and run down the newly-formed path until you reach a Map Piece and a ship. After playing another minigame with the cannons you'll stand face to face with Cap'n Blacksmoke.
Fighting him is relatively easy until he uses his smoke screen - then you'll have to track him based on where he shoots from and smother him with powder kegs, or sneak a few hits in in melee.
After you deal sufficient damage to him, the smokescreen will subside - get as much damage as you can before the smokescreen is deployed again. Near the end of combat, Blacksmoke will cease fire, content with tossing bombs around - easy to dodge, but they hurt. Really bad.
