Pirates do not like the British Soldiers that work for the King, and it always makes sense because he is constantly trying to throw them in jail and then toss away the key. For a pirate that would be in the end of the world! Until they escape of course but you need to make sure that pirates keep sailing the waters to find treasure. The way you can help them is to find forts and blast them! Assign the right power and angle to your pirate cannon then blast it off to where it will knock out all of the soldiers in the fort! You will collect the coin from their pockets to fund even more fort blasting levels.
