A very timely post.
For anyone interested in researching relatives lost at sea during wartime or otherwise (or indeed anyone with an interest in maritime history), this site is a fascinating database of wrecks and their history.

My grandfather was Royal Navy and died on convoy duty in sight the Cornish coast (his home county) in 1942. I knew most of details but through that website I was able to fill in many gaps - including the names of the RN and Merchant Navy sailors who died with him.
There is even a link to a Utube vid of some local divers visiting the wreck - something I had always hoped to do but it is at a depth requiring mixed gas, technical diving qualifications and skills which I never had in my prime and am unlikely to get now. The Utube vid has a comment from a Danish man saying his great grandfather was the captain of the ship - I am tempted to contact him but not sure.
Anyway, probably too much information but might be an interesting resource for others interested in researching lost relatives.
More local to me these days, the Brecon Beacons are littered with the remains of RAF, RCAF and USAAF aircraft lost during the war and immediate post war years. There will be various informal acts of remembrance at many of these sites over next few days - below s a link to a guide with directions and descriptions of the various wrecks.
