Dictionary of American Naval Fighting Ships, May 2016
William Daniel Wagner — born on 16 May 1924 at Cincinnati, Ohio — enlisted in the U.S. Naval Reserve on 7 February 1942 and attended the U.S. Navy Armed Guard School at Little Creek, Va. Attached to SS Steel Navigator’s armed guard crew, Seaman 2nd Class Wagner was killed in action when his ship was torpedoed on 19 October 1942.
In the days before the sinking, his ship had been separated from its convoy, ON 137, and battered by a hurricane. The heavy seas and high winds forced a dangerous shift in ballast, which in turn caused a precarious 40-degree list to port. The Navy gun crew volunteered to go below and soon was hard at work performing the exhausting task of shifting sand and water ballast for the next 30 hours without relief, until the ship had momentarily passed out of danger.
However, the German submarine U-610 had spotted the straggler and closed at periscope depth. Upon sighting the submarine some 4,000 yards off her starboard beam, Steel Navigator went to general quarters, and her Navy armed guard manned their guns. Forced down by the gunfire drawn from the merchantmen, U-610 temporarily abandoned her plans for attack. Later, however, at 1445, the U-boat closed the ship and sank her with torpedoes. Seaman 2nd Class Wagner was among the casualties from Steel Navigator‘s crew.
