Southern Victory

Southern Victory, also known as "Timeline 191", is a series of alternate history novels (eleven in all), written by American author Harry Turtledove. They are set in a world where General Lee's offensive into Maryland succeeds, ending the American Civil War much earlier and allowing the Confederacy to win a decisive victory. Although on the surface an alternate history, the series is really a retelling of real-world history, with the United States loosely representing Russia and the USSR and the Confederacy as Germany.
