Bring the Jubilee

Blurb

Bring the Jubilee by Ward Moore is a 1953 novel of alternate history, with elements of steampunk. The point of divergence occurs in July 1863 when the Confederate States of America wins the Battle of Gettysburg and subsequently declares victory in the "War of Southron Independence" on July 4, 1864, after the surrender of the United States of America. The novel takes place in the impoverished rump United States in the mid-20th century as war looms between the Confederacy and its rival, the German Union. History takes an unexpected turn when the protagonist Hodge Backmaker, a historian, decides to travel back in time to witness the moment when the South won the war.
The title, "Bring the Jubilee", is a reference to the chorus of the popular military song "Marching Through Georgia".
