Does not meet WP:SOLDIER & sig RS coverage not found link, just passing mentions and / or non RS mililtaria books.

No de.wiki article exists. Did not hold a significant command and topped out as Captain. Successful completion of missions (enemy ships and tonnage sunk), etc) is not part of SOLDIER. Please also see a note at MilHist Talk Archives for background behind the redirect. In summary, per the outcome of the discussion at Notability:People on notability of Knight's Cross recipients: permalink, certain recipients were deemed non notable and WP:SOLDIER has been modified accordingly: diff. The articles of these recipients are being redirected to alphabetical lists.
