Princeton University Professor of History and Pulitzer Prize winning author James McPherson looks at Lincoln as a military leader, strategist, and commander. Professor McPherson argues that Lincoln studied military strategy through books and eventually came to understand the war better than many of his generals did. He asserts that the war would only be won by defeating armies rather than conquering territory and this was one of Lincoln's chief concerns. This event was recorded at Labyrinth Books in Princeton, New Jersey.
