First things first, we need to deal with the fort's defenses. Honestly, they're not too tough. A few well-placed mortar shots from your ship, combined with a broadside or two, should clear them out pretty quickly. Once the coast is clear, sail your ship over and dock within the green beam of light.

Now, hop off your ship and follow the path. You'll need to climb the stairs until you reach a blocked gate. Scale this up to the top, then drop down on the other side. Turn right and head straight for the building marked with the red objective marker. Take out any enemies that get in your way.

When you get to the building, look for a wall run opportunity to get up over the door. Grab the wooden beam above and pull yourself up. Enter through the window. Once inside, turn right and clear out the enemies on the balcony through the next doorway. You'll see some cages stacked against the wall; use these to climb up to the higher platform, and then get onto the roof.

From the roof, make your way to the paved area with the garden nearby. Go to the edge where you see the red objective marker. Highlight your target and hit the assassinate button for an air assassination.

After the assassination, climb back up and enter the door marked with the green objective marker. Take out the enemy inside. Doing this will liberate the fort!
