A research reference map, not a period photograph, marking the location where U.S. Navy Lieutenant Junior Grade W.E. Bancroft was lost on 26 December 1952 during the Korean War, in the Sea of Japan off Korea's east coast. Documents such as this are compiled during archival or family research to pinpoint the circumstances of a serviceman's loss, supplementing personal photographs and official records in reconstructing his service history.
