[2] In the evening of 13 February 1944 Henry was sailing along the coast near Hustadvika Bay[3] by Hestskjær Lighthouse[4] off the port of Kristiansund in Møre og Romsdal county.

[5] Two of Henry's crewmen were lost in the ship's sinking, her captain John Olav Gustav Dommersnes and the stoker Johan Wåge Larsen.

One of the main uses of the incident in Nazi propaganda was in a recruitment drive aimed at convincing Norwegian sailors to join the German Kriegsmarine.

The Royal Norwegian Navy remains adamant that Irma and Henry were without lights or national markings and were sailing as a convoy escorted by a German naval trawler.

[6] Henry was honoured together with Irma 16 September 2002 when King Harald V of Norway unveiled a monument to the people lost on the two ships, and led a memorial ceremony at sea near the site of the 1944 sinking of the two vessels.
