Within a decade of Long completing the house, "the whole political situation in the Colonies changes," Gleason said. Long's sympathies were clear in documents indicating that he offered to help the Continental army find food, horses and wagons. He bought confiscated Tory property, and in 1781, he sold his house on South Ann Street and moved to the Herring Run area in Baltimore County, where he owned property. Mentioned in his 1799 will was property in three counties in Virginia as well. He died in 1808.
