Hello Erling and Platon,

very interesting discussion, many thanks, it does raise a few new questions though :-)

* what was the maximum depth at which a british submarine mine could be placed, i.e. how long was the chain that was connected to the sinker (hopefully I got the terminology right)?

* do you have any information about port of departure, cargo, destination and possible casualties? Couldn't find that info on the site.

Best regards,

Jan-Olof
