Assassin's Creed III Remastered

Sending a convoy is a way to make money. You must send one to each area described in the description. This will become easier to do as you gain supplies and build up your homestead. You must also have accessed at least 1 general store in each area. When in the convoy menu (accessed from the Accounting Book found in the manor or general stores), you need to press down on the analogue stick to pick a different area's store.
