- SOPO Editor’s Note: The location for the “Union Intrenchments” is way off. They were located further west, with the right resting on the James River south of Farrar’s Island, and the left anchored on the Appomattox River (the river next to “Broadway” on the map) southwest of Port Walthall. See this detailed map of Bermuda Hundred and compare it to this newspaper map. ↩
