This work is set in August 1863. Having pursued the remnants of the defeated Army of the Potomac up to the banks of the Susquehanna, General Robert E. Lee is caught off balance when news arrives that General Ulysses S. Grant, in command of over seventy thousand men, has crossed that same river, and is advancing down the Cumberland Valley towards Virginia. The two brilliant generals will now meet in a massive battle that will decide the outcome of the war. As with "Gettysburg", "Never Call Retreat" will focus on an operational battle, a slugging match between two armies, this time with both armies led by brilliant commanders.
