Breakthroughs by Harry Turtledove

Harry Turtledove begins The Great War: Breakthroughs as he has begun the previous two novels in the series, with George Enos living his life and demonstrating how the great events are effecting the everyman. Once past the reintroductions of his characters, Turtledove returns to the meat of the action, bringing characters from various storylines together, such as his team up of President Theodore Roosevelt, General George Custer and Major Irving Morrell in Tennessee, and playing them against each other. An ongoing combination of characters is the game of cat and mouse between Roger Kimball’s submersible, The Bonefish and George Enos’s destroyer USS Ericsson. Incidents such as these play themselves out along the entire twisting line of the Southern and Northern fronts.
