One night, three men approach undercover of the darkness, what happens?

Guy Wortman and his friends are angry about Bill joining the Confederacy, so they start paying visits to the cabin with vicious taunts and threats of further trouble for people who side with the Southern Rebel. The men left switches outside the cabin, which were meant as a threat (fire) aimed at the Creightons for standing behind their sons who were fighting for the rebels.
