The Pulitzer Prize-winning author reveals how Lincoln won the Civil War and invented the role of commander in chief as we know it. As we celebrate the bicentennial of Lincoln's birth, this study by preeminent, bestselling Civil War historian James M. McPherson provides a rare, fresh take on one of the most enigmatic figures in American history. Tried by War offers a revelatory (and timely) portrait of leadership during the greatest crisis our nation has ever endured. Suspenseful and inspiring, this is the story of how Lincoln, with almost no previous military experience before entering the White House, assumed the powers associated with the role of commander in chief, and through his strategic insight and will to fight changed the course of the war and saved the Union.
