        Gettysburg: The Three Days combines text, animation and 3D maps to                  explain the greatest battle in the U.S. Civil War.                  The program accurately recreates the contours of the Pennsylvania                  battlefield as it looked during the first three days of July 1863 through                  topographical maps, based on U.S. Geological Survey data and other                  sources.                  A previous Civil War title, Antietam/Sharpsburg, focuses on that battle                  in Maryland on September 17, 1862, the bloodiest day in American                  history. Text boxes in each program present short biographies of one                  dozen top army commanders, plus details on other participants, military                  units and landmarks.                  Both titles also contain orders of battle and full listings by state of all                  regiments engaged. Grace Technologies, Delaware, OH, (800) 778-6629.                  W
