The Blakely gun could be found in two batteries of the Stuart Horse Artillery, Army of Northern Virginia:
(1) Chew’s (Va.) Battery, known as the Ashby Artillery because of its early association with Turner Ashby’s famed “Laurel Brigade” of Stonewall Jackson’s Valley District. This unit was the first horse artillery battery in the ANV. It was organized on Nov. 11, 1861, with Roger Preston Chew of Charles Town, Va. (today, W. Va.) as captain. Chew had one Blakely among his guns through the great cavalry battle of Brandy Station, where it “ended its life.”
(2) Hart’s Washington (S.C.) Battery, commanded by Capt. James F. Hart, which was generally associated with Hampton’s Brigade. Hart had four Blakelys in the Maryland campaign (1862) and three at Gettysburg, having lost one to Union counterbattery fire in the Loudoun Valley fighting following Brandy Station.
