Memory 02: 02 Murder And Mayhem

Part 1: Locate
Sail to the green circle on the map to find the target ship 'Benjamin'. The area is restricted, so avoid enemy ship cones of vision. The optional objective is to find the target without entering combat. The target ship is located off the coast at coordinates 242,236. Follow the coast of the southern island to the target area and use the spyglass to identify the ship. Completing this without being spotted fulfills the optional objective.

Part 2: Naval Battle
Once the target ship is identified, nearby enemy vessels, including a frigate and the target schooner, will become hostile. Engage and destroy both ships using your ship's weapons. After sufficient damage to the target vessel, a cut-scene will play.

Part 3: Assassinate
After regaining control, you will be on an island with many soldiers. The objective marker indicates the target's location above ruins to the south. Your entry point is a second set of ruins to the left. Work your way to the ruins east of the target's location, using stealth or combat. Climb the ruins to the top and eliminate the Gunner. Ensure you lose or kill any hostiles and become anonymous before approaching the target's location undetected. Use the branch in the southwest corner of the ruins to access the treetop path to the target's platform. Enter the ruin through the crack in the wall ahead and hide in the stalking zone. Use sleep darts on the three stationary guards under the stone archway to the west, then knock them out. Locate the tall pillars on the western part of the area and use them to jump to the main structure where the target is. Climb to the top and perform an air assassination on the Templar from the ledge to complete the mission and the optional objective.
