5. The Lusitania
The RMS Lusitania, a British ocean liner, was torpedoed by a German U-boat on May 7, 1915, off the coast of Ireland. The attack resulted in the deaths of 1,198 people, including 128 Americans, and played a significant role in shifting public opinion in the United States, contributing to its entry into World War I. The sinking of the Lusitania shares similarities with the Titanic disaster, both involving large, luxurious ships and significant loss of life, yet the circumstances and outcomes differed markedly (nationalww2museum.org).
