The three deaths were the only Americans killed as a result of attacks on American ships by German submarine until 16 March 1917, when diplomatic relations had irreparably broken down just before the declaration of war. American official reaction to the incident was determined by President Woodrow Wilson under the advice of U.S. Secretary of State William Jennings Bryan and Counselor to the State Department Robert Lansing. Bryan favoured reconciliation with Germany and avoidance of war, but this policy was becoming increasingly unpopular and was opposed by his subordinate Lansing.
