During World War II, the U.S. Navy took over a large area in the north western portion of York County which became known as Camp Peary. All residents of the entire towns of Bigler's Mill and nearby Magruder were removed.
Camp Peary later became well known as "The Farm," a training facility for the U.S. Central Intelligence Agency (CIA). Although the roads and structures are still there and occupied, access to the base is still restricted. The 100 acre (400,000 m²) Biglers Millpond occupies the site adjacent to the York River.
