Confederate incursions from Falls Church, Minor's Hill and Upton's Hill—then securely in Confederate hands—occurred as far east as the present-day area of Ballston. On August 17, 1861, an armed force of 600 Confederate soldiers engaged the 23rd New York Infantry near that crossroads, killing one. Another large incursion on August 27 involved between 600 and 800 Confederate soldiers, which clashed with Union soldiers at Ball's Crossroads, Hall's Hill, and along the modern-day border between the City of Falls Church and Arlington. A number of soldiers on both sides were killed. However, the territory in present-day Arlington was never successfully captured by Confederate forces.
