Fort Tillinghast

About

Fort Tillinghast was a small lunette that the Union Army constructed in Alexandria County (now Arlington County), Virginia, as part of the Civil War defenses of Washington (see Washington, D.C., in the American Civil War). Fort Tillinghast stood about 0.6 miles away from Arlington House, the Union-occupied estate of Confederate General Robert E. Lee.
