Get primed for the anniversary by watching The Gettysburg Electric Map like you’ve never seen it before. Photographs, graphics and combat action have been added to enhance the viewing experience.The original map was researched, designed and constructed in the late 1930s and featured electric lights of red and blue to represent the positions and movements of Confederate and Union armies. This program is based on the original electric map concept and uses “electrical lights” in the same manner but three-dimensional and computer generated from the original terrain map. The narration is an adaptation of the original script for the electric map from 1938. The script was written by park historian D. Scott Hartwig, and your narrator is John O’Grady.
