Set up an ambush for the British Platoon
Talk to Big Dave outside his house, to learn that the Redcoats are coming to try him for treason. Big Dave asks that you follow him, and he explains that he has collected some powder kegs which you can use to set up an ambush. You will have 30 seconds to setup the ambush. Place the keg on the trail where the British Platoon will be coming from (See "X" in screenshot below for a strategic powder keg placement, between the wall and the tree). Don't place it too close to where your allies are standing or it might kill them. Shoot the keg with your pistol as the soldiers march through, and then finish off any soldiers who survived the blast.
After you are done with the first wave, place another keg in the same position, and repeat.
