Sequence 5-1: The Forts

Optional Missions:

- Use the mortar to damage the fort

- Use a running assassinate to kill the officer

Head to Nassau's tavern for a scene. Travel to the Punta Guarico to the east next. Approach the fort and you can start the mission as soon as you can. Use your ship's mortar to damage the fort defenses to complete an optional objective. After completing that optional objective, you can proceed destroying the fort defenses using your ship's cannons.

After destroying the fort defenses, dock then enter the fort. Don't bother with the normal enemies and just find the officer. Ensure that you have your hidden blades equipped then perform a running assassination to complete the optional objective. It is effectively done by taking the target by surprise.

Next, head to the war room and open it to find Torres inside. After the scene, the fort will be captured and the region will become unrestricted. All the collectibles and locations in the area will be revealed as well. Before heading to the next mission, you can collect all collectibles in the fort and complete a Naval Contract as well.
