Confederate troops inflicted heavy damage to the Antietam Aqueduct during the Monocacy Campaign in July 1864.
The fourth of eleven stone aqueducts on the Chesapeake & Ohio Canal, the Antietam Aqueduct was completed in 1835 to carry the canal over Antietam Creek. In July 1864, during the Monocacy Campaign, the Confederates inflicted serious damage to the Antietam Aqueduct. In an effort to disrupt a Union supply line, soldiers tore out much of the masonry on both sides of the structure and removed some of the stonework from two of the arches. By the end of September, however, the company had completed enough repairs to the aqueduct to resume navigation.
