CONCORD, Mass., Nov. 14, 2016 /PRNewswire-USNewswire/ -- The Friends of Minute Man National Park today released the final archaeology report on the Parker's Revenge battle - the April 19, 1775, encounter in which Lexington's Captain John Parker engaged the British Regulars on their march back from Concord to Boston. "In this centennial year of the National Park Service, it is wonderful to be able to reveal "new" history tied to the opening of the American Revolution,"said Nancy Nelson, superintendent of Minute Man National Historical Park. The 320-page report summarizes historical research on the battle, details the full range of technologies deployed in the archaeological research and describes battle tactics likely utilized by both colonial and British forces. The project findings are noteworthy, especially because only one brief witness account the battle has ever been identified by historians. Technologies utilized in the research informed formal excavations and 1775 battlefield reconstructions. These methods included: 3D laser scanning, GPS feature mapping, and geophysical surveys including metallic surveys,ground penetrating radar, magnetic gradient and conductivity/magnetic susceptibility. Taken together, the technologies enabled researchers to locate a farmhouse that figured prominently in the battle terrain, to recreate the actual 1775 battlefield landscape and battlefield features and even to model exactly what combatants could and could not see at various positions along the battle road. Artifacts discovered included 29 British and colonial musket balls from the battle.Thelocation and spatial patterning of the musket balls recovered enabled archaeologists to interpret the exact positions where individuals were standing during the battle — and then outline battle tactics most likely deployed. "Using an integrated approach to interpreting this battlefield enabled us to literally peel back time and expose the artifacts that tell the story of Parker's Revenge," said Project archaeologist Dr. Meg Watters. The report indicates that Captain Parker positioned his men at the edge of a woodlot on an elevated slope above the battle road. This particular site had two distinct advantages: it provided a clear view to see the advancing British forces and the landscape featured a number of large boulders and trees that provided cover.
