re. "Alabama"
I'm rather sure, this is connected to <CSS Alabama>.
On 11 June of 1864, Captain Semmes brought thr to Cherbourg, France, for repairs. The Union steam sloop Kearsarge soon arrived off the port, and, on 19 June the Alabama steamed out to do battle. In an hour of intense combat, she was reduced to a sinking wreck by the Kearsarge's guns. As Alabama disappeared beneath the surface, her surviving crewmen were rescued by the victorious Federal warship and by the English yacht Deerhound.

That very year, Geneva convention No. 1 was signed.
And the "Geneva Convention for the Amelioration of the Condition of the Wounded, Sick and Shipwrecked Members of Armed Forces at Sea
of August 12, 1949" are clearly referring to a similar situation, what happend to and with the crew of the 'CSS Alabama'.
Well, I couldn't find any websites in English or German as proof for my theory, but it sounds quite nice (and I'm going through French websites later :wink: ).
