What was the title of Michael Shaara's 1975 Pulitzer Prize-winning novel?

The Killer Angels was Michael Shaara’s 1975 Pulitzer Prize-winning novel.

Published in 1974, the historical novel dramatizes the Battle of Gettysburg during the American Civil War. It presents events through the viewpoints of several Union and Confederate officers, including Robert E. Lee, James Longstreet, Joshua Lawrence Chamberlain, and John Buford.

Shaara combines documented historical events with imagined dialogue and interior perspectives. The book’s central subject is the three-day battle in Pennsylvania from July 1 to July 3, 1863, often considered a turning point in the war.

The novel later served as the basis for the 1993 film Gettysburg. It is sometimes mistaken for a conventional biography of one commander, but its structure shifts among multiple military perspectives. Shaara’s son, Jeff Shaara, later wrote additional Civil War novels connected to the story.
