A large group of Confederate agents infiltrated from Canada into Maine with the object of robbing the bank in the Washington County town of Calais. American officials in Canada were able to warn the town, however, and the raiders were met with heavy resistance at the bank and in the streets. Three of the raiders, including the leader, Captain William Collins, were captured. They were tried as bank robbers and sentenced by a Maine court to three years in prison. (By John Osborne)
