"The Lusitania sinking was widely used for propaganda by both sides. A German medallion was struck commemorating the event, correctly claiming that the ship had carried munitions. The British produced a counterfeit of the medallion, which was widely circulated. The British public interepreted the sinking as a premeditated attack on women and children. The destruction of the Lusitania was also a considerable shock to the American public and was a factor in America's decision to enter the war."
