In a war of brother versus brother, theirs has become the most famous broken friendship: Union general Winfield Scott Hancock and Confederate general Lewis Armistead. Michael Shaara’s The Killer Angels (1974) and the movie Gettysburg (1993), based on the novel, presented a close friendship sundered by war, but history reveals something different from the legend that holds up Hancock and Armistead as sentimental symbols of a nation torn apart.
