Tannenwald

Tannenwald was a commander of the Kriegsmarine. In 1939, he was a staff officer for Admiral Karl Dönitz.

When U-30 returned from the Scandinavian campaign, Tannenwald met its skipper, Julius Lemp, and ordered him to report to Donitz "at his convenience" for a debriefing. After the debriefing was interrupred by news of a coup, Lemp asked Tannenwald for information, and Tannenwald urged him to return to his assigned barracks.
