Gen. William Mitchell House

The Gen. William Mitchell House, also known as Boxwood or the Gen. Billy Mitchell House was the country estate and home of General Billy Mitchell (1879–1936) during the last ten years of his life, from 1926 through 1936. Mitchell was an American general who is regarded as the father of the U.S. Air Force. He is regarded as one of the most famous and most controversial figures in American airpower history. The house was declared a National Historic Landmark in 1976. It is located about .5 mile south of Middleburg on Virginia Route 626, straddling the county lines of Fauquier and Loudoun Counties. Part of the estate is now home to Boxwood Estate Winery.

Description and history
Boxwood is 120 acre located south of the Loudoun County town of Middleburg, extending along the northwest side of VA 626 roughly from the city line to the highway's junction with Virginia Route 705. The centerpiece of the estate is a cluster of buildings that are set well back from the road. The main building is the farmhouse, which has at its core an 1826 farmstead. Now L-shaped in plan, it is $2 1/2$ stories in height, with stone walls and wooden trim. The original farmhouse portion has a bellcast roof that curves down to shelter a porch.

The original farmhouse was built in 1826 by William Swart, and passed through several hands before its purchase in 1925 by Elizabeth Mitchell, the wife of General Billy Mitchell. The Mitchells added an ell to the southwest in 1925 and also built an outbuilding that served them as a library. It was their home until Mitchell died in 1936, and has not received major alterations since then. Mitchell, a horse enthusiast, kept horses and wrote extensively during his years there, expounding on his theories regarding the military use of air power.
