A German U-Boat sinks the Lusitania, which is carrying several Americans, resulting in heightened political tension between Germany and the US. As a result of a U.S. campaign, Germany issued an apology and promised payments on 5 October. On 7 December, President Wilson asked for a military fund increase.
