Got a brilliant book called Bismark, gives the History
of the vessel and all involved in her demise! Then it shows the underwater descovery of Bismark and inside stills. Shows that where she sank, co-ordinates, there was no sign, but on further investigation they found a debris trail, and actually she sank onto an underwater mountain and slid down about a mile off course!1 The pics are beautifull and also contain great illustrations!
Will have to dig it out and post the details!
