On Feb. 15th, Hill recorded in his diary: “Snowing fast all day. Our Regiment worked all day on Fort Beauregard, 2 miles east of Leesburg. Cannonading heard from the direction of Centerville.”
The fort, according to independent historian Craig Swain of Leesburg, was actually due south of the town. No engineer drawings have ever been found, but it is believed to have been in the shape of a rectangle. It was on the hilltop in Swain’s photo, above the white buildings (an outlet mall) in the middle distance. Its cannon would have covered the Alexandria-Leesburg turnpike.
The fort (from which no fighting apparently was done) was obliterated years ago to make room for a gated subdivision appropriately named Beauregard Estates.
Hill said the 13th, apparently taking turns with the other regiments at Leesburg until the fort was finished, returned to work on it on the 18th and again on the 23rd.
