Second, he adopted an interpretation of the battle that encompassed a much smaller area than is indicated by contemporary accounts. Historians believe his limited funds, coupled with landowners' demanding top dollar, influenced his interpretation. This mis-led researchers and historical groups who relied on his work; they placed historical monuments and markers in the wrong spots. It also hampered government efforts to acquire land or resist development in areas outside the original area designated as battleground by Schenck. Since his time, the expanding city of Greensboro approached and encircled the park with private development, destroying some battlefield areas. When the National Park Service assumed responsibility for the park, their historians and researchers sought to clarify the accuracy of the locations of the battle. The renewed accuracy places many of the monuments in locations that had very little reference to the actual battle.
