Sinking of the HMS Lusitania

On May 7, 1915, the RMS Lusitania, a 31,500-ton Cunard liner traveling from New York to Liverpool, was struck by a single torpedo fired by German submarine U-20 under the command of Kapitänleutnant Walther Schwieger. The ship sank in 18 minutes, taking 1,198 lives with it—128 of them American citizens. The Lusitania had been repeatedly warned about U-boat activity in the Irish Sea; the German embassy had even placed advertisements in American newspapers days before departure cautioning travelers against booking passage. Yet the ship's captain, William Thomas Turner, maintained the vessel's speed and did not zigzag, standard evasion tactics of the era.

The attack occurred during Germany's unrestricted submarine warfare campaign, a desperate attempt to starve Britain into submission by sinking any vessel supplying the islands. Germany classified the Lusitania as an armed merchant cruiser, partly because it was registered to carry munitions—though the ship was predominantly a passenger vessel. Whether it actually carried weapons remains contested by historians. The German government defended the sinking as a legitimate act of war; American newspapers and politicians condemned it as mass murder.

The disaster hardened American sentiment against Germany, though the U.S. would not formally enter the war for another two years. President Woodrow Wilson demanded Germany cease unrestricted submarine warfare, leading to the "Sussex Pledge" of May 1916, in which Germany agreed to warn merchant ships before attacking. This restraint lasted only until early 1917, when Germany resumed unrestricted attacks as a calculated risk—a gamble that ultimately accelerated American entry into the war. Secretary of State William Jennings Bryan, who had argued for stricter neutrality, resigned in protest over Wilson's firm response to the sinking.

The Lusitania became a symbol of German ruthlessness, weaponized in British and American propaganda. Survivors' accounts, press coverage, and illustrations by artists like Fred Spear (whose "Enlist" recruitment poster featured a drowning child from the wreck) shaped public memory of the disaster. Decades later, the wreck itself became a historical artifact; the ship rests 300 feet down off the Old Head of Kinsale, Cork, visited by salvagers and documentary filmmakers seeking answers about exactly what was in its hold.
