Join the editors of TIME to observe the 150th Anniversary of the Civil War in a richly illustrated chronicle of the confl ict that changed America. It's an immense subject-a battle between freedom and slavery, waged across the breadth of the still-expanding nation over a period of four years-and TIME has created an oversized volume to tell the story in the grand style it deserves.

To bring the tale to life, the book focuses on little-seen photographs and original artifacts from the period: sketches from soldier's diaries, unusual and rare military and political memorabilia. And it brings us face-to-face with those who lived through the period, presenting scores of excerpts from the letters and diaries of soldiers, offi cers and statesmen. Yet the book also captures the full sweep of the war, telling the tale in chronological fashion, as the war evolves from a quiet beginning to become a mammoth struggle that consumed the divided nation. Here are the great generals: Ulysses S. Grant, Robert E. Lee and "Stonewall" Jackson. Here are the great battles, from Bull Run and Antietam to Gettysburg and Shiloh. Here are the latest discoveries and analysis by scholars of the conflict. And here are fascinating, informative graphics that reveal the war in fresh, clarifying detail. Here is a larger-than-life conflict, reported and illuminated in a larger-than-life oversized edition from TIME.
