Working in partnership with the state of Maryland in 2001, the Fund negotiated the purchase of conservation easements over four parcels, a total of 53 acres, on the battlefield where, on September 14, 1862, the Confederates’ effective defense on the mountain – in essentially three separate battles – kept open their line of retreat until they were protected by darkness. The armies then moved toward Antietam.
The funding was provided by The Maryland Department of Natural Resources and the Department of Transportation (TEA-21 funds). The easements are held by the Maryland Environmental Trust.
In 2004, in partnership with the state of Maryland and The Civil War Preservation Trust, the Fund protected an additional 26 acres on the battlefield, the site of McClellan's headquarters and 10 acres which include a historic house used as a field hospital.
