Gareth,

Of your list of submarines lost.

Did you realise K13 sank TWICE, once on trials (before acceptance) as K13. She was raised from Loch Gare (Gareloch?) and entered as K22, almost exactly a year after the first sinking (IIRC a year less a day), she was sunk off May Island. Amazingly there was one man on K22 who had been on K13 (C.P.O. Oscar Moth), when she was again raised, Moth refused to serve on her (or any K Boat) again.
