A "Dark, Gloomy Cleft"

— Mosby's Confederacy and Second Manassas Campaign —

The gap to your left between Biscuit Mountain (the northern promontory of Pond Mountain) on the south and Mother Leathercoat Mountain on the north, described as "that dark, gloomy cleft" in an 1862 issue of Frank Leslie's Illustrated Newspaper, was the site of several Civil War skirmishes. The most significant action, August 26-29, 1862, is described on the adjacent markers and illustrated on the map. Although technically a Confederate victory, the confrontation illustrated for the Federals the strategic importance of the gap and the rail line in the movement of troops and supplies. For the remainder of the war the Federals occupied the gap whenever Lee's infantry was thought to be in the area. In spite of Federal surveillance, Col. John Singleton Mosby and his raiders frequently camped in the area and used their intimate knowledge of the difficult terrain to stage surprise raids or evade capture.

Chapman's Mill (now Beverley's Mill), located directly across I-66, also played a role in the August 1862 action and in subsequent skirmishes. Built in 1759 and enlarged to five stories in 1858, its upper floor windows were used by sharpshooters from both sides to attack or defend the pass. The mill survived the 1862 action with only minor damage but by 1864 it was little more than a shell. Mill owner John Chapman filed suit against the U.S. to recover $5,194.59 for damage suffered in July and October 1863, which rendered the mill inoperable and destroyed the business. Chapman never recovered from his losses. He was committed by his family to the lunatic asylum in 1864 and died in 1866. The mill was bought and restored in 1870 by Col. Robert Beverley and continued in operation until 1951.
