Thanks for the additional information on the Torpedo Badges. Noting the raw terms of service at the outset of the thread, a while ago I came across another rather quirky regulation applied to a possibly sizeable number of merchant seamen lost at sea in WW1- and probably carried over into WW2 subsequently. In 1917, a relative’s ship was torpedoed without warning and sank within 4 minutes. Defensively armed and under ‘Admiralty Orders’ at the time, the vessel had joined a convoy in Gibraltar a few days earlier, where she had also embarked four "distressed seamen" for transit back to the UK. They were some of the surviving crew from another merchantman torpedoed and sunk off Cape Spartel three weeks previously. In that attack, two of the latters’ shipmates were killed, both firemen, one originally from Lisbon and the other a Dutchman. Their Master was taken prisoner aboard the U-boat; the remaining survivors seemingly left to their fate in boats and life-rafts. That first ship (also under Admiralty Orders) had been conveying coal and Naval stores to Gibraltar. Twenty perished when my relative’s vessel was lost, but only 17 names are commemorated on the plaque at Tower Hill. Three of the four “distressed seamen” who were also killed - from accounts at Kew - do not seem to have been commemorated anywhere as war casualties. Their deaths are corroborated in a shipping company archive note, but in addition to not being listed on any plaque at Tower Hill, neither are they seemingly named on memorials in their wartime home-ports, although this may be unintentional. I could only attribute this to their being not formally articled as crew on the fateful voyage home and therefore technically passengers. This was confirmed by the CWGC, with whom I raised a subsequent query. So, the hapless three: Engage (possibly re-engage) to serve on a ship that had been under Admiralty Charter for two years. Survive her loss from enemy action and being adrift at sea for several days. In Gibraltar, "distressed" and possibly injured from an ordeal in which two crewmates were killed, they are chalked onto another Admiralty Orders vessel for a return to the UK and perish as a consequence of a further enemy act a few days later. However, because they are Merchant Marine, they do not receive any formal recognition etc .... despite at least two of the three seeming to have had significant previous service. Unsung, indeed.
