During WW1, on several occasions, the FdU (Fuhrer der Unterseeboote) tried to slip U-boats into the Scapa Flow to attack the British Fleet.

      The first attempt was on 6 August 1914 when FdU sent the boats U-5, U-7 to U-9, U-13 to U-18 in a bold move to attack the British Fleet at Scapa Flow. It didn't go well U-5 and U-9 had to turn back due to engine trouble, U-13 was lost without a trace and U-15 was sunk by the light cruiser HMS Birmingham, when trying to move into attack. The rest of the boats that left port achieved nothing. 

       On 23 November however U-18 (Kptlt) Hans von Hennig) did manage to penetrate Scapa Flow but was sighted and sunk.

       Then towards the end of hostilities in 1918 UB-116, (Oblt.z.S. Emsmann) with a volunteer crew of 34 officers penetrated Hoxa Sound at Scapa Flow. UB-116 was however detected by hydrophones and sunk by mines with the loss of all hands.

        As we know it would be 21 years later before the U-boat arm would be able to slip Gunter Prien in U-47 into Scapa Flow and conduct a successful attack on the British Fleet.

         Anyone else interested in WW1 U-boats and their operations?

 Hi !

Yes, I am always interested in U-Boote History. WWI in rather new to me, but I would like to learn more about the U-Boot Arme in the Great War.

 OK! I get the hint! I will attempt to get some photos of my work an the site by this weekend if possible. I have two U-Booten finished: U-69, a Type VIIC, and U-295 aType VIIC/41. I have started on my conversion project of U-47. these are all 1/72 scale.

Thanks for the kind comments. I know and my father knows that when he is gone, that part of history will be gone too.

Regards,

 Ok!

I will ask him in a couple of weeks. I will be traveling down to Illinois to see him.  I will ask him about the U-805 surrender off the coast of America in 1944. I have heard it before, but I will try to get him to give me more detail if he can remember.  He also has some interesting bits on his life here in America as a PoW.

Regards,
