In 1868, celebrated Civil War photographer Alexander Gardner traveled to Fort Laramie to document the federal government's treaty negotiations with the Lakota and other tribes of the northern plains. Gardner, known for his iconic portrait of Abraham Lincoln and his visceral pictures of the Confederate dead at Antietam, posed six federal peace commissioners with a young Native girl wrapped in a blanket. The hand-labeled prints carefully name each of the men, but the girl is never identified. Please join Politics and Prose in welcoming Martha A. Sandweiss, author of The Girl in the Middle.
