Book excerpt: On the afternoon of April 9, 1865, some sixteen thousand Union troops launched a bold, coordinated assault on the three-mile-long line of earthworks known as Fort Blakeley. The charge was one of the grand spectacles of the Civil War, the climax of a weeks-long campaign that resulted in the capture of Mobile--the last major Southern city to remain in Confederate hands. Historian Mike Bunn takes readers into the chaos of those desperate moments along the waters of the storied Mobile-Tensaw Delta. With a crisp narrative that also serves as a guided tour of Alabama's largest Civil War battlefield, the book pioneers a telling of Blakeley's story through detailed accounts from those who participated in the harrowing siege and assault.
