Three miles south of Newnan on July 30th, Maj. Gen. Joseph Wheeler with 1,400 Confederate cavalry caught and routed the Federals, captured about 2,000 men, several ambulances, a full battery and released 500 Confederate prisoners. Here General Wheeler whipped the "pick" of the Federal cavalry and saved Newnan from capture and possible destruction. 038-2 GEORGIA HISTORICAL COMMISSION 1955

The Story
In July 1864, as the Atlanta Campaign raged, Union Brig. Gen. E.M. McCook led 3,600 cavalry on a raid to wreck the railroads feeding Atlanta and free the thousands of Federal prisoners held at Andersonville. Three miles south of Newnan, Confederate Maj. Gen. Joseph Wheeler caught the raiders with a far smaller force and routed them, capturing some 2,000 men, a battery, and freeing 500 Confederate captives.
Why it matters
Wheeler's victory at Brown's Mill blunted a bold Union effort to sever Atlanta's supply lines and liberate Andersonville, buying the Confederacy precious weeks in the fight for the city.
The story behind this marker
AI contextThe era
The summer of 1864 was the hinge of the Civil War in Georgia. General Sherman's armies had pushed south from the mountains toward Atlanta, the Confederacy's great rail and manufacturing hub, and the fate of the city — and with it, many believed, the fate of the war and the coming presidential election in the North — hung on whether its supply lines could be cut. The Atlanta Campaign was a long series of flanking marches, entrenchments, and cavalry sweeps across the red-clay country of north Georgia.
Railroads were the arteries of this campaign. Atlanta lived and fought by the lines that fed it, and both sides knew that severing those rails could do what a frontal assault could not. That made the countryside south and west of the city — places like Coweta County and the town of Newnan — into strategic ground, even miles from the main battle lines.
Into this picture came another shadow: Andersonville, the notorious Confederate prison camp in south Georgia, where tens of thousands of Union soldiers were held in desperate conditions. The chance to wreck the railroads and free those prisoners in a single bold stroke was a temptation the Union command could not resist.
People & events
In late July 1864, Brigadier General E. M. McCook set out with a large mounted force on exactly that kind of raid — to tear up the railroads below Atlanta and, if fortune allowed, to reach and release the thousands of Federal captives held at Andersonville. It was a deep, daring thrust into enemy country, the sort of operation that could pay off spectacularly or unravel just as fast.
It unraveled. A few miles south of Newnan on July 30, Confederate cavalry under Major General Joseph Wheeler — one of the South's most aggressive mounted commanders — caught up with the raiders. Though Wheeler's force was much smaller, he moved fast and hit hard, and the raid came apart in a running fight.
The result was a rout. The marker records the tally plainly: roughly two thousand Federals captured, along with ambulances and a full battery of artillery, and five hundred Confederate prisoners set free in the confusion. Wheeler had beaten what the marker calls the "pick" of the Federal cavalry and, in the bargain, spared Newnan from capture and the destruction that so often followed an army's passage.
Its place in the American story
Brown's Mill mattered because of what it prevented. A successful raid might have crippled the rail lines feeding Atlanta and thrown open the gates at Andersonville; instead, the Union effort was smashed, and the Confederacy bought precious weeks in the struggle for the city. In a campaign measured in yards of trench and miles of torn-up track, the failure of a cavalry raid could ripple outward for a long time.
The episode captures the peculiar role of cavalry in this war — fast, far-ranging, and capable of striking at the enemy's lifelines behind the front. Raids like McCook's were high-risk gambles, and Brown's Mill is a reminder that they could end not in glory but in mass surrender deep in hostile territory.
It also sits within the larger tragedy the raid was meant to address. Andersonville remained in operation, and the suffering there would become one of the war's enduring scandals. That the marker frames the raid partly as an attempt to free those men gives Brown's Mill a weight beyond the count of prisoners and guns.
If you visit
Newnan today is a graceful county-seat town southwest of Atlanta, and the battlefield lies a few miles south in rolling Coweta County farmland. It is peaceful ground now, and the contrast between that calm and the chaos of a cavalry rout is part of what makes standing here worthwhile.
Use the marker to get your bearings on scale and surprise: a smaller Confederate force overtaking and shattering a much larger raiding column. Picture mounted men moving fast through this country, the roads and rail lines that were the whole point of the fight, and how quickly a deep raid could turn from threat to disaster.
Brown's Mill fits well into a broader tour of the Atlanta Campaign, which spreads across north and west Georgia in a chain of battlefields and markers. If you're following that campaign, this is the place to remember that Atlanta's fate was decided not only in the trenches ringing the city, but out on the railroads and back roads where cavalry hunted cavalry.

Birthplace of a Confederate Hero (William T. Overby)
Coweta County, GA
William Thomas Overby, born on this site in the 1840s, enlisted in the 7th Georgia Infantry in 1861 and later rode with Mosby's Rangers, the daring Confederate cavalry command that harassed Union forces in Virginia. Captured near Front Royal in September 1864, he was offered his freedom in exchange for revealing the Rangers' hiding place; he refused, and was hanged without trial.
Bethsaida Baptist Church and Cemetery
Fulton County, GA
Bethsaida Baptist Church was formed in 1829 and served for decades under Pastor John S. Dodd, who led it for 50 years. In 1864 Union forces occupied the original wooden church as a headquarters, reportedly using its pews as horse troughs. The sanctuary later burned, the congregation merged with another to form United Baptist Church, and the Bethsaida site eventually closed, leaving behind a cemetery with graves dating to the 1800s.
Baird's Div
Clayton County, GA
As the Atlanta Campaign reached its climax on August 30, 1864, Davis's 14th Corps moved from Red Oak toward the Fayetteville Road, splitting into columns for the approach. At this crossroads on the Flat Shoals Road, Baird's division swung northeast and then southward, its march briefly halting the passage of two divisions of the 4th Corps until it could complete the turn. The realignment set the stage for the fighting at Jonesboro that would finally sever Atlanta's supply lines.
Bellevue, Home of Sen. Benjamin Harvey Hill
LaGrange, GA
Benjamin Harvey Hill rose from a Troup County farm to become one of Georgia's foremost orators — a Whig legislator who opposed secession yet became a staunch defender of the Confederacy in its Senate. After the war he vigorously fought the Reconstruction Acts and, with Senator John B. Gordon, pressed President Hayes to remove federal troops from the South, later serving in the U.S. Senate until his death in 1882. His home, Bellevue, was built in 1854–55.
