/" Ever since the fall of Washington, the American continent has been left in utter disarray. Small, weak states fight each other and a horde of hell trying to survive, to fight to become strong, colossal in size, yet fall to the hands of brothers or the dead. With Canada in shambles, and Mexico left to defend themselves from the hordes in Baja, there must be a change in the power, and it needs to happen now. As the remnants of the old United States, with the help of newly-appointed General William Tecumseh Sherman, it has been decided among us within Headquarters that we will reunite the states ourselves. Starting tonight at 11:01 P.M., we will begin our march to the original colonies, liberating towns, homes, and cities and striking down any of the undead in our path. My friends, must it be clear once we reach Washington and liberate it from the grasp of the horde, then we shall raise the flag of the colonies high and reestablish our great nation. The boys are ready, we are ready. May god be with us. "/ - Allen Pinkerton
I want this to sound a little insane and farfetched. By this point, Allen Pinkerton was halfway submitted to insanity and had talked of "colonizing Atlantis," or whatever that meant. Nevertheless, still happening because the administration is too scared to disobey him because of how utterly unstable he is. (credits to @Aperture_Innovations for the map)
