An ancestor of his being a Confederate general there, Peterson studied the November 1863 Battle of Chattanooga in detail, and concluded that, while there was an element of luck in the US victory, the outcome was mostly determined by good decisions on one side and poor decisions on the other. He identifies 19 critical decisions in five categories and time periods: nine decisions that shaped the battle itself, three pre-battle decisions the day before the battle began, three decisions made on the first day of the battle, three decisions reached on the second day of battle, and one post-battle decision two days after the battle.
