The 51st Pennsylvania and the 51st New York of the Union IX Corps crosses what later became Burnside’s Bridge at the Battle of Antietam on September 17, 1862. This rustic stone bridge over Antietam Creek is a popular subject for dioramas. This one is a 25mm rendition by artist Brian Sullivan.
University of Maryland graduate Brian Sullivan creates and sells custom dioramas of various Civil War battles. His website has photographs of several of his creations. Have a look! These look great on desks or on shelves.
