Fall of Atlanta: William T. Sherman, the commander of the Union Army, sent his cavalry to wreck the Georgia Railroad. The commander of the Confederates, John Bell Hood, decided to launch a flank attack on Sherman's army. His forces would march around the Union’s army and attack their flank and their wagon trains. Hood's forces launched their surprise flank attack much later than planned. The Confederate flank surprise attack was a failure because instead of running into the medical tents and wagons they ran straight into a group of Union infantry. The Union general McPherson was surveying the battle and went down a wagon road where he unexpectedly ran into a Confederate division of troops. He and his fellow troops retreated and started galloping away when general McPherson was shot and killed. Then Confederate forces attacked and partly overran the Union line. They were then stopped by Union forces positioned on top of a hill. The Confederate troops gave up the fight and retreated. The Union side also stopped fighting and returned to their original positions. Both generals counted their casualties. The Union had 3,722 dead, wounded, or missing and the Confederacy had 5,500 dead, missing, or wounded.
