I'm at the Fort, the cannon is loaded. I have to pull the rope behind the cannon to open the door, but nothing is happening. Help please.

Hi Tammy,

Did you do this a little earlier in the game:

Take the rammer from the wall and use it on the cannon with gunpowder to get the gunpowder properly tamped. Return the rammer to the wall.

Make a new tackle and then use tackle on right hook of cannon cart.
