On 27th June 1918, 116 miles west of Ireland, HMHS "Llandovery Castle" was attacked by the German submarine U-86 and torpedoed, regardless of the fact that she was clearly marked as a Hospital Ship.
The Commander of the submarine, whose name was Patzig, interviewed the survivors in the lifeboats to try to find evidence that arms were being carried but no such evidence found. Patzig then gave the order to dive and started to destroy the lifeboats so that there would be no survivors.
However, one lifeboat did manage to survive and their story was told. After the war, Patzig could not be found but two officers who had manned the guns were found, tried and sentenced to hard labour. The pair escaped but were never recaptured.
