During the afternoon of 9 Aug. 1862, Confederate Maj. Gen. Thomas "Stonewall" Jackson's division, led by Maj. Gen. Richard S. Ewell and Brig. Gen. Charles S. Winder, fought Union troops led by Maj. Gen. Nathaniel P. Banks about three miles south. Winder was mortally wounded. Banks attacked Winder's troops, who buckled under the Federal assault until Jackson rallied them. Assisted by the arrival of Maj. Gen. A.P. Hill's Light Division, the Confederates struck back early in the evening and Banks's troops retreated north. Darkness halted the Confederate pursuit here, short of Culpeper. Cedar Mountain was the first clash of the Second Manassas Campaign.
