Submarine Surfaces in the Middle of a City – Then Maintenance Workers Peek Inside

The 1971 mystery entry

One detail in the logbook had attracted less attention than the others, mostly because it appeared on the final page and seemed, at first, like a clerical anomaly. After the last wartime entry in November 1943, there were twenty-seven blank pages. And then, on the very last page of the book, a single line in handwriting that analysis would later confirm was different from Voss’s. It was written in English, in a neat, unhurried hand, and it said: Completed. See file AR-7. H. The entry was dated 3rd September 1971.
