At dawn on New Year's Day, Confederate Major General Thomas J. Jackson, already known as "Stonewall," marched a large force north from Winchester, Virginia with the aim to cut the Baltimore and Ohio Railroad and clear the Union forces from the area. Three days later, he occupied Bath in Morgan County (now part of West Virginia) and the federal forces withdrew across the Potomac into Washington County, Maryland. Jackson's artillery shelled Hancock, Maryland across the river the next day but did not follow. (By John Osborne)
