#LUSITANIA - A new TV documentary on the National Geographic Channel follows what might be the last expedition to the wreck of the Lusitania, in a bid to get to the bottom of the century-old mystery surrounding the ill-fated vessel.
On 7 May 1915 the passenger liner RMS Lusitania was sunk by a torpedo from a German U-boat off the coast of Cork, sending 1,198 lives to their doom.
But theories abound that there was more to the disaster than the torpedo strike, and that the ship's cargo hold contained precious art and illegal munitions.
Dark Secrets of the Lusitania attempts to uncover what really happened, using the latest submersible technology to see further into the shipwreck than ever before.
As previously reported on Afloat.ie, Gregg Bemis - the elderly American who owns the wreck of the former Cunard cruise liner - hoped last year to discover once and for all what secrets the ship really holds in what may be the last major dive to the wreck site.
Dark Secrets of the Lusitania premiers on Sunday 15 July at 7pm on the National Geographic Channel, available on Sky and UPC.
