Archaeology at Fort Mifflin is a community-based University of Pennsylvania research project directed by Eternal Soldier in collaboration with the Weitzman School of Design and the Penn Museum Center for the Analysis of Archaeological Materials (CAAM). The project investigates the fort described as "the most under-investigated, under-appreciated, forsaken site in our nation’s military history”: Fort Mifflin in Philadelphia.
Veterans in Design Workshop discussion with Eternal Soldier Exec Director Kimberly Max Brown, PhD
Veterans were our partners in research design. Through a series of design workshops, we learned what about Fort Mifflin was important to them and what features they felt would be most crucial to interpret from the viewpoint of the average soldier. Alongside possible remnants of the great 1777 Siege of Fort Mifflin, Veterans advised that we should investigate diet and medicine as these are critical to service members on active-duty.
Our research design incorporates geophysics, history, historic preservation, archaeobotany and excavation to focus on the garrison---officers, enlisted, military families, civilians and community members---stationed at the site from the Revolutionary War through WWII.

Fort Mifflin arguably experienced the greatest artillery bombardment of the American Revolution. In later periods, it served as a military prison and as an artillery depot. To deliver greater detail about food and medicine, the project researches archaeobotanical remains---seeds, pollen, charcoal, etc.---that help us identify which plant taxa were present at the fort. Additionally, we investigate the archaeological connections to Fort Mifflin’s Revolutionary War sister site, Fort Mercer, located at Red Bank Battlefield and visible across the Delaware in National Park, New Jersey. Our design also emphasizes pressing questions of site conservation and preservation.
We welcome all members of the public who wish to volunteer, especially Veterans. Our next season in the field is scheduled for February-March 2026. Fill out the form below or send us an email at info@eternalsoldier.org to let us know you want to play a part in our work.
Archaeology at Fort Mifflin is a professional program of excavation investigating fort inhabitants, post-Revolution use of the site, battle related artifacts and site preservation and conservation. Veterans and the public will help dig, work with specialists and process artifacts (screening, washing, cataloguing). Please note: Children under 14YO cannot participate in the dig.
Come ready to get dirty.
Archaeology at Fort Mifflin is funded by the American Battlefield Protection Program of the National Park Service.
