When President Roosevelt called for the country to be the great Arsenal of Democracy, Detroit helped turn the tide against fascism with its industrial might. Locals were committed to the cause, putting careers and personal ambitions on hold. Factories were retooled from the ground up. Industrialist Henry Ford, First Lady Eleanor Roosevelt, aviator Charles Lindbergh, legendary boxer Joe Louis, future baseball Hall of Famer Hank Greenberg and the real-life Rosie the Riveters all helped drive the city that was forging thunderbolts for the front lines. With a panoramic narrative, author Gregory D. Sumner chronicles the wartime sacrifices, contributions and everyday life of the Motor City.
