Union troops from the Second Division of the 15th Corps commanded by General William B. Hazen are seen here at Fort McAllister in Richmond Hill, Georgia. Hazen led an attack of 4,000 troops on the fortification in December 1864. After a 15-minute battle, his men overwhelmed the 230 defenders, capturing 15 guns and taking the surviving Confederate soldiers prisoner. The skirmish opened the way for the attack and capture of the Confederate city of Savannah a couple of weeks later. Photo Credit: Bettmann/Getty Images
