Lee & Grant: Lee & Grant compares the lives of revered opposing generals Robert E Lee and Ulysses S Grant, from their backgrounds - Grant was from a humble clan while Lee was part of the first family of Virginia - to their military tactics, examining their careers in the armed forces and the Civil War skirmishes where they acquired their leadership skills. Battlefield maps and detailed descriptions take us through each key altercation, showing how decisions made by Grant and Lee were not always popular, or even successful. But 4 July 1863 saw both Grants greatest victory (at Vicksburg) and Lees greatest defeat (Gettysburg), which together changed the course of American history.
