Lusitania had a short career. She was torpedoed by the SM U-20 a German U-boat on May 7, 1915 during WWI. Lusitania sank in only 18 minutes, 8 miles off the coast of Ireland. 1,198 of the 1,959 passengers and crew on board were killed. Because she was a passenger liner and not a war ship, public opinion in many countries turned anti-German. Many of the passengers happened to be American so Lusitania was instrumental in bringing the United States into WWI.
