The ship you're referring to is the RMS Lusitania, which was sunk by a German U-boat on May 7, 1915. This incident resulted in the deaths of 1,198 passengers, including 128 Americans, and sparked outrage in the United States. The sinking contributed to growing anti-German sentiment and played a significant role in shifting American public opinion towards entering World War I.

Britain blockaded Germany during World War 1, preventing food and materials from reaching the country. The Germans hoped to break the blockade by deploying submarines that would destroy British maritime power. Also, the submarines attacked cargo ships that brought supplies to Britain.
