The Battle of Aldie took place on June 17, 1863, in Loudoun County, Virginia, as part of the Gettysburg Campaign of the American Civil War. Maj. Gen. J.E.B. Stuart's cavalry screened Gen. Robert E. Lee's Confederate infantry as it marched north in the Shenandoah Valley behind the sheltering Blue Ridge Mountains. The pursuing Union cavalry of Brig. Gen. Judson Kilpatrick's brigade, in the advance of Brig. Gen. David McMurtrie Gregg's division, encountered Col. Thomas T. Munford's troopers near the village of Aldie, resulting in four hours of stubborn fighting. Both sides made mounted assaults by regiments and squadrons. Kilpatrick was reinforced in the afternoon, and Munford finally withdrew toward Middleburg. Background Late in the spring of 1863 tensions grew between Union commander Joseph Hooker and his cavalry commander Brig. Gen. Alfred Pleasonton because of the latter's inability to penetrate Maj. Gen. J.E.B. Stuart's cavalry screen and gain access to the Shenandoah Valley to locate the Army of Northern Virginia, which had been on the move since June 3rd. On June 17, Pleasonton decided to push through Stuart's screen. To accomplish his goal he ordered Brig. Gen. David McM. Gregg's division from Manassas Junction westward down the Little River Turnpike to Aldie. Aldie was tactically important in that near the village the Little River Turnpike intersected both the Ashby's Gap Turnpike and Snicker's Gap Turnpike, which respectively led through Ashby's Gap and Snickers Gap of the Blue Ridge Mountain into the valley. Battle Early that very same morning, Colonel Munford led the 2nd and 3rd Virginia Cavalry eastward across the Loudoun Valley from Upperville through Middleburg to Aldie on the Bull Run Mountains on a reconnaissance and forage mission. He established a line of pickets in Aldie to watch for enemy activity and withdrew his two regiments northwest of town on the Snicker's Gap Turnpike to camp on the farm of Franklin Carter. About 2 pm, Gregg's advance column of the 2nd and 4th New York, 6th Ohio, 1st Maine, 1st Rhode Island, and 1st Massachusetts, under the command of Brig. Gen. Judson Kilpatrick arrived in Aldie. Just west of the village the 1st Massachusetts encountered Munford's pickets and drove them back. Around the same time, the rest of Munford's brigade (the 1st, 4th, and 5th Virginia Cavalry, under the command of Col. Williams Carter Wickham) arrived at Dover Mills, a small hamlet on the Little River west of Aldie. Wickham
