The Great War: Walk in Hell(The Great War‪)‬

The Great War: Walk in Hell is the incredible second book of Hugo Award–winning history professor Harry Turtledove’s alternate history tetralogy of World War I.
The first book, The Great War: American Front, was chosen by Publishers Weekly as one of the Best Books of 1998.
In this startlingly vivid portrait of a world torn apart by war and strife, causality is the law of the land as the events of history are woven into many new and unexpected tangents. The Confederate States of America enter an alliance with Britain and France, while its disgruntled black
population openly revolts under the red banner of Communism. Busy fighting diehard Mormons and tricky Canadians, the United States enters a dangerous pact with Kaiser Wilhelm that will lead to the bloodiest fighting of all time.
With war raging around the globe, fear spreads as horrifying new weapons of mass annihilation are introduced, leaving no one safe.
