Sequence 7-3: Commodore Eighty-Sixed

Optional Missions:

- Kill 3 guards from stalking zones

- Air assassinate Chamberlaine

Follow the guards across the town while keeping distance and avoiding causing any unnecessary commotion. Keep tailing them until they reach their camp by the shore. The camp has several stalking points where you can execute unknowing guards. These kills count towards the first optional objective. Once done, swim to the ship in the ocean afterwards.

Climb up to the mast in the middle and climb the net halfway to get in range. To reach it without alarming the guards, climb on the bow of the ship then use the ratlines to reach the main mast. There's a gunner in the masts who can spot you and ruin your assassination attempt so put him to sleep then knock him out permanently. Once Chamberlaine when he is aligned right under you, jump and air assassinate him.
