The Battle of Old Town was a U.S. Civil War battle fought on August 2, 1864 as part of the Valley Campaign of 1864. Union forces amassed and took high ground at Oldtown, Maryland on the Potomac River in an attempt to trap Brigadier John McCauslandâÂÂs Confederate States Army raiders behind Union lines.
McCausland's forces had previously sacked and burned Chambersburg, Pennsylvania, on orders of Lieutenant General Jubal A. Early. The survival of McCausland and his section of the Army of Northern Virginia is credited to a single artillery shot directed at close range by Maryland Line Lieutenant John R. McNulty from his Baltimore Light Artillery command, which was supporting Brigadier Bradley Tyler JohnsonâÂÂs 1st Maryland Infantry. Lieutenant (later Major) McNultyâÂÂs shot has been called âÂÂone of the most brilliant achievements of the war.âÂÂ
