The Battle of Brown's Mill was fought July 30, 1864, in Coweta County, Georgia, during the Atlanta campaign of the American Civil War. Edward M. McCook's Union cavalry, on a daring raid to sever communications and supply lines in south-central Georgia, was defeated near Newnan, Georgia, by Confederate forces under Joseph Wheeler. The failure of McCook's column and a concurrent ill-fated raid by George Stoneman forced William T. Sherman to lay siege to the city of Atlanta.
During the Atlanta Campaign, Gen. William T. Sherman, wanting to avoid the necessity of laying siege to the city, ordered two columns of Federal cavalry on a series of raids south of Atlanta in an attempt to cut off supply and communication lines. Maj. Gen. George Stoneman led the cavalry of the Army of the Ohio to the southeast, while Brig. Gen. Edward M. McCook’s First Division of the cavalry of the Army of the Cumberland was to sever railroads southwest of the city. He was to link with Stoneman and then seize the Andersonville prison camp and free the 32,000 prisoners held there.
Crossing the Chattahoochee River on a pontoon bridge erected at Smith's Ferry, McCook's cavalrymen reached Palmetto, where they cut the Atlanta & West Point Railroad. They captured and burned over 1,000 Confederate supply wagons at Fayetteville on July 28. General McCook also gained a reputation for condoning and encouraging the destruction of civilian property. Early the next morning, his raiders reached Lovejoy's Station, twenty-three miles south of Atlanta, and began wrecking the Macon & Western Railroad. However, McCook called off the raid and turned back across the river when Stoneman failed to appear as planned.
Nevertheless, as they tried to return to the main army, McCook's division was attacked near Brown's Mill, three miles south of Newnan, by Confederate cavalry under Joseph Wheeler. McCook wanted to surrender, but instead, let his officers lead their battalions out separately. McCook, thoroughly defeated, lost 1,285 men, 1,200 horses, several ambulances, and two pieces of spiked artillery, as well as 100 killed and wounded. Wheeler also freed some 300 Confederate prisoners that McCook had previously captured. Wheeler's losses were 50 men.
Stoneman's forces also met with disaster. General Stoneman was captured, becoming the highest ranking Union officer to be a prisoner of war during the Civil War. Many of his and McCook's enlisted men ironically wound up in Andersonville, the target of their raid. Brown's Mill changed the course of the Atlanta Campaign, forcing Sherman to abandon his efforts to use cavalry to cut Atlanta's railroads and compelling him to begin a lengthy siege against his wishes.
The American Civil War (1861–1865) was the deadliest conflict in American history, killing an estimated 620,000 to 750,000 soldiers and an unknown number of civilians. The Confederate States of America, formed by eleven seceding Southern states, faced the Union in four years of warfare across 23 states and territories. Major engagements included First and Second Bull Run, Antietam (the bloodiest single day in American history, September 17, 1862), Chancellorsville, Gettysburg (July 1–3, 1863), Vicksburg (surrendered July 4, 1863), and Sherman's March through Georgia and the Carolinas (1864–1865). President Lincoln issued the Emancipation Proclamation on January 1, 1863, transforming the war's stated purpose to include the abolition of slavery and enabling the enlistment of approximately 180,000 Black men in the United States Colored Troops. Confederate General Robert E. Lee surrendered to Ulysses S. Grant at Appomattox Court House on April 9, 1865. The war resolved the question of secession and ended American slavery, though Reconstruction would face sustained resistance in its attempt to secure civil rights for formerly enslaved people.
