EXPLANATIONS BELOW
Concept note-1: -The disaster set off a chain of events that led to the U.S. entering World War I. A German U-boat torpedoed the British-owned steamship Lusitania, killing 1, 195 people including 128 Americans, on May 7, 1915. The disaster set off a chain of events that led to the U.S. entering World War I.
Concept note-2: -RMS Lusitania was torpedoed by a German U-boat on 7 May 1915. The luxury passenger liner was crossing the Atlantic from New York to Liverpool when the German submarine U-20 fired without warning.
Concept note-3: -On that day, the British luxury liner, the RMS Lusitania, set sail from New York for Liverpool; six days later, twelve miles off the southern coast of Ireland, she was torpedoed by a German submarine and sank.
Concept note-4: -Knowing all this today, we can confirm that the Lusitania was a war crime, all right, but it was a British/German co-crime, not just a German crime.
