In 1888, David Schenck, searching for battlefield artifacts, found the upturned bones of three unidentified soldiers on a farm north of the park. From buttons found in the grave, supposedly marked “USA,” Schenck concluded that the dead were American Continentals killed in action. The location of the remains suggests they were part of Kirkwood’s Delaware company on the right flank of the first line. Unlike the militia in that line, the Delaware troops were seasoned professionals of equal caliber to the British regulars, and their remains were reburied here in honor of their valor.
