A British loss table survived through American records

The source is a British table scheduled for release on 28 November 1944. The surviving copies came through the American Office of War Information, while British collections tended to retain the final end-of-war tables rather than every interim version. A publicly accessible copy was traced through the United States Merchant Marine site by reverse-searching the data. The passage models source criticism by tying wartime statistics to their publication context, preservation history, and present-day route of access.
