Never Call Retreat: Lee and Grant: The Final Victory is the conclusion of an alternate history trilogy by former Speaker of the U.S. House of Representatives Newt Gingrich, William R. Forstchen, and Albert S.

General George Armstrong Custer learns of Lee's movement of the pontoon train from a loyal Union railroad man.

Custer decides it is an important enough prize that he must abandon his current mission, leaving General Darius N. Couch without proper screening forces.

After Lee's surrender, Grant paroles Lee and his army, and declares a 30-day, unilateral truce, ostensibly to give the paroled Confederates time to return home, but more so to give Confederate President Jefferson Davis time to "come to his senses" and realize the war has been lost.

"[2] Brad Hooper in his review for Booklist said that "as in the previous volumes in the trilogy, the authors' research is impeccable, and their presentation brings events down to a personal level, and, as in any good alternative vision of history, the reader is left believing it could really have happened this way.
