SS Robin Moor
 SS Robin Moor was a Hog Islander steamship that sailed under the American flag from 1919 until being sunk by German submarine U-69 on 21 May 1941 before the United States had entered World War II after allowing the passengers and crew to disembark. This sinking of a neutral nation's ship in an area considered until then to be relatively safe from U-boats and the plight of her crew and passengers caused a political incident in the United States.
