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, a hundred miles to the northwest and is advancing down the Cumberland Valley toward Virginia. The two brilliant generals will now meet in a massive ballet that will decide the outcome of the war. In Never call retreat, Newt Gingrich and William Forstchen bring all of their critically-acclaimed talents to bear in what is destined to be a Civil War classic.
