Hi Bootneck1958
I first found out about Otto and his comrades in 1990 during a tour of Benbecula.
The graves were unknown by the authorities for years- the local fishermen knew about them as they used the old school house as a layover in bad weather but I wrote to the Volksbund and the CWGC and they are now recogised as wargraves. I did quite a lot of research into this boat and the crew. It appears Otto and his two comrades floated ashore. They were only able to identify Otto through personnel effects. They current probaly carried them from the wreck site ( they may have been in life jackets) and deposited them on the beach below they are buried.- no other of the crew have known graves. The uboat was ripped apart by the destroyers. Cant remember if here were any survivors off hand.
I'll try and search my research out and send you a copy if I can find it.
Bootneck as in Marine?
Cheers
