The public history project described herein was performed at Blakeley Historic Park, Alabama. The project included the preparation of survey maps depicting the location, size and directional orientation of Confederate and Union earthworks, which were used during the siege and battle of Fort Blakely in April 1865. The project also included historical research and documentation of findings relative to the design, construction and use of the Confederate fortifications at Blakeley Park. This research attempts to answer the questions; who ordered or directed the earthworks to be built, who designed them and supervised their construction, when were they built, and who provided the labor for their construction? Recommendations are made for the acquisition potential of earthworks found that were outside of present park boundaries. In addition, recommendations are made for preservation of existing earthworks within the park. The historical essay on the Confederate fortifications advances the argument that the design and construction effort was beset with shortages of engineers needed for design and supervision, shortages of labor needed for construction, and a shortage of troops to man the fortifications. Because this project combined modern day Global Positioning System surveying and Geographic Information System mapping technology with historical research methodology, collaboration with faculty experts in the College of Engineering and Computer Science was essential.
