Sinking of RMS Lusitania
On 7 May 1915 a German submarine torpedoed the Cunard liner Lusitania off the Irish coast, killing roughly twelve hundred of the 1,960 people aboard in eighteen minutes. Three inquiries, in Cork, London and New York, examined what happened, but they disagreed among themselves and with each other about the death toll, the cause of a mysterious second explosion, and whether a liner carrying declared war cargo was a legitimate target. The sinking hardened American opinion against Germany, though the United States did not enter the war for almost two more years.
