It's time to return to Connor. Fast travel to the frontier and then from there to Boston. When you get there, track down Sam Adams in the northern part of the city. He'll be talking to some of his compatriots. You will talk with him as you walk through the city and you will stumble upon an interesting situation.
After you split up with Sam Adams, you'll find a couple of Red Coats assaulting a Frenchman. You can start by trying to assassinate a couple with your hidden blades though it may not be possible so simply deal with them in open combat. When you are done with these few Red Coats, get away from the area and find a way of lowering your notoriety. There is a Town Crier nearby that you can bribe if you have the money to do so. Be sure to do this because you need to avoid reaching notoriety level 2 on your way to meet up with Sam Adams to meet one of the constraints.
Meet up with Sam Adams at the Green Dragon Inn to find out that Johnson is getting his funding through tea. You need to head to the waterfront and destroy the tea containers using the barrels of gunpowder but limiting the usage of firearms. When you get near the docks, find one of the targets and look nearby for a powder keg. These shipments are usually guarded and this is a restricted area so they will investigate on sight so be careful. You can engage these men as long as you don't shoot them.
Take your powder keg and throw it at tea shipment. Get some distance and shoot it to blow it up. Do this for each of the tea shipments. Feel free tom shoot from any comfortable position since you don't always have a good conspicuous angle. For instance, shooting from a roof will be far enough away to not get hit by the explosion, have a clear line of sight but not be visible to guards.
With the large shipments taken care of, it's time to take care of the smugglers in town. Find men carrying around tea crates similar to the one you bumped into coming out of the Green Dragon. They are marked on your map so it shouldn't be too hard to find them but their paths tend to take them by many Red Coats who will attack you if you get too close to them. You can try and wait for the smuggler to enter a safe area before attacking him or you can get close to him and kill him before the guards can attack. This is faster but then you need to escape from the guards.
When all three of the smugglers have been dealt with, the memory will be complete.
