The RMS Carpathia, famous for having rushed through the night to rescue the survivors of the RMS Titanic disaster in 1912, was carrying out her duties as a WWI troop ship when she was torpedoed by U-Boat 55 and sank.
She lost all but 5 of her passengers before her survivors were rescued by the sloop HMS Snowdrop.
As an aside, one of the many Doughboys the Carpathia brought to Europe to fight the Hun was a young Frank Woodruff Buckles, a Missouri boy who when he died in 2011 at age 110, was the last American WWI veteran.
Today in History, June 9: 1915 – William Jennings Bryan, US Secretary of State, resigns. After a German U-Boat had torpedoed a British passenger ship, the Lusitania, resulting in the deaths of 128 Americans, Bryan sent a conciliatory, almost apologetic message to the German government without President Wilson’s consent. Germany felt impowered and issued an aggressive statement, to which Wilson replied in kind, leaving little doubt that America would not tolerate the sinking of non-combatants. Germany backed off, for a time, and Bryan resigned in protest, believing Wilson was leading the nation towards war. Bryan had been an impressive orator, 3 times a candidate for president, and L. Frank Baum’s inspiration for the Cowardly Lion of the Wizard of Oz in 1900.
