Siege artillery in the American Civil War were used by the Federal troops as their trenches approached Fort Wagner and field artillery was placed in the trenches to defend against possible Confederate sorties. While Fort Wagner was subject to near constant bombardment from the batteries listed in the table below, as approaches neared the fort's ditch the bombardment increased. Fire from U.S. Navy ships, particularly the USS "New Ironsides", proved very effective. The navy were able to skip the round shells from their XI-inch Dahlgren guns off the water, over the ramparts, and into the fort. Several heavy Parrott rifles that had been directed against Fort Sumter
Conclusion of the American Civil War was the last battle of the American Civil War involving large numbers of United States Colored Troops. The Battle of Fort Blakely happened six hours after Lee's surrender to Grant at Appomattox. In the course of the battle, Brigadier General St. John Richardson Liddell was captured and surrendered his men. Out of 4,000 soldiers originally, Liddell lost 3,400 that were captured in this battle. About 250 were killed and only some 200 men escaped. The successful Union assault can be attributed in large part to African-American forces. Unaware of Lee's surrender on April 9 and the assassination of President Lincoln
