The sinking of the Lusitania on Friday, 7 May 1915 during the First World War, as Germany waged submarine warfare against the United Kingdom which had implemented a naval blockade of Germany.

The sinking of the Lusitania: The Sussex pledge

After the Lusitania disaster, the German government had privately decided to abandon the practice of firing upon passenger liners. But in March 1916, acting against orders, a German submarine fired without warning upon the French steamer Sussex, killing about eighty people. Four of the twenty-five Americans aboard were injured. The ship had not possessed the usual markings that indicated a passenger ship; it was painted black, and its bridge looked like that of a warship. When the German captain spied it traveling outside the routes that the British Admiralty had designated for passenger ships, he suspected it was The Germans had made a mistake, and would certainly have made reparation for the disaster. Wilson, however, took the opportunity to issue an ultimatum to Germany demanding that unless she abandoned submarine warfare entirely, the United States would sever diplomatic relations with her. The result was the Sussex pledge of May 1916, in which the German government made a major concession to Wilson. Although they would not abandon submarine warfare altogether, the Germans would not sink enemy merchant ships, armed or unarmed, without warning and without saving the lives of the people aboard, unless the ship in question opened fire or attempted to flee. This was an enormous concession, since the Germans, in effect, granted enemy merchant ships the opportunity to fire the first shot.


The pledge, however, was conditional. The German government expected Wilson to put pressure on the British government to abandon its hunger blockade and to allow food to make its way to Germany. Should the American government not achieve such a concession from the British, the German government would have complete freedom of action. Not surprisingly, Wilson accepted the concession and refused the condition. Since America’s neutral rights were absolute and inalienable, they were to be enjoyed regardless of the behavior of another belligerent. Wilson thus felt free to continue his policy, which he insisted on calling “neutrality,” of holding one belligerent strictly accountable for its violations of international law but doing next to nothing about those of another belligerent.
