In this history of the "Lost Battalion" of World War I, Alan D. Gaff tells for the first time the story of the 77th Division from the perspective of the soldiers in the ranks. In Blood on the Argonne, Gaff describes these soldiers in human terms, identifying them as New York City draftees and replacements from the western states who all came from a wide mix of ethnic backgrounds. Portraying the soldiers through their surviving memoirs, photographs, and papers, Gaff gives voice to the thoughts and feelings of the men who endured one of the most famous and compelling episodes of warfare in the twentieth century.
