U Boat Death Trap – A submarine has been discovered on the seabed, seven miles off the coast of Cornwall. German in origin, which one is she, why is she here and what sank her?
A routine naval survey of the seabed has discovered two shipwrecks lying side by side in sixty metres of water. However it is impossible to identify the vessels or the reasons for their sinking from the surface. Only a technical dive can reveal the answers.
The dive reveals a ship so mangled that identification is impossible, but nearby is the characteristic shape of a German submarine. Which U-boat was it? What happened to its crew? Did she hit the other vessel by accident or design? Was it something completely different, a mine, perhaps, the area, after all, was near an active minefield. Is it just an eerie coincidence that the two wrecks ended up laying side by side?
Top submarine historian Innes McCartney teams up with German U boat expert Axel Niestlé in an attempt to identify the mystery submarine and establish what exactly happened. Taking detailed pictures of the wrecked submarine and trawling both British and German archives they inch towards a positive identification of the wreck.
During their research, the discovery of two more submarines only a few miles away deepens the mystery. Are they in anyway connected? Further analysis of wrecks confirms that they, too, are German U-boats from the 2nd World War, and they both show similar catastrophic damage.
With analysis from explosives experts, the cause of their demise can at last be confirmed. Their conclusion opens a whole new area of investigation, revealing a carefully planned British operation specifically targeting German U boats, an operation that has remained secret for over sixty years.
Innes and Axel, having positively identified the submarines also uncover the human cost of the loss of these U-boats. Relatives of the crews on board find out for the first time what actually happened to their loved ones. Misled as to the fate of their menfolk, they can finally pay their last respects.
