Mildred Fish-Harnack was guillotined in Berlin on February 16, 1943, on the personal instruction of Adolf Hitler -- the only American woman executed as an underground conspirator. Yet as World War II ended and the Cold War began, her courage, idealism and self-sacrifice went largely unacknowledged in America and the democratic West, and were distorted and sanitized in the Communist East. Only now, with the opening of long-sealed archives, can the full story be told.

Resisting Hitler is based on extensive interviews with Fish-Harnack family, friends and associates; it draws on personal correspondence and formerly classified German and Soviet KGB files and recently released CIA and FBI dossiers. It describes the life of a Wisconsin girl whose intelligence and beauty captivated a visiting scholar, Arvid Harnack, a member of a distinguished German academic family. It explores for the first time the complex familial connections of the Harnacks, Delbrucks and Bonhoeffers, twelve of whom were executed for resistance acts. And it details Mildred's friendship with Martha Dodd, daughter of FDR's ambassador to the Third Reich, whose affair with aSoviet diplomat led to his death.
