Sylvanus Cadwallader, a war correspondent for the Chicago Times and later for the New York Herald, was attached to General Grant's headquarters from 1862 to 1865. He enjoyed rare access to personalities (Lincoln, Sheridan, and Lee) and events (Vicksburg, Chattanooga, City Point, and Potomac), and he makes them come alive here. Cadwallader also includes information about his own role in constraining and concealing Grant's drinking. Through his pages the real Grant emerges. The manuscript of Three Years with Grant was edited and annotated by Lincoln biographer Benjamin P. Thomas and first published nearly a century after the Civil War. Brooks D. Simpson is the author of Let Us Have Peace: Ulysses S. Grant and the Politics of War and Reconstruction, 1861-1868 and other books. He is an associate professor of American history at Arizona State University.
