One of the largest cavalry battles of the war took place outside Newnan GA on July 30, 1864. Fannie Beers and Kate Cumming, two nurses assigned to hospitals in town provide colorful accounts of events at Newnan GA. Anyone able to use a musket was armed and sent out to the battlefield.

Here's a history of the 9th Tennessee Cavalry Battalion.

The battalion was part of Ashby's Brigade, one of two brigades available to Wheeler during his pursuit of McCook's raiders. Along with Roddey's dismounted cavalry, "Red" Jackson's mounted forces and whatever soldiers could be assembled from the hospitals, these men helped to defeat McCook's weary Federals at Brown's Mill. Had Wheeler managed the battle differently, the entire Federal force might have been captured or killed.
