4 mayo 1916 año - Sussex Pledge

Descripción:

The Sussex Pledge was a promise given by the German Government to the United States of America on May 4, 1916, in response to US demands relating to the conduct of the First World War. Specifically, Germany promised to alter their naval and submarine policy of unrestricted submarine warfare to stop the indiscriminate sinking of non-military ships. Instead, merchant ships would be searched and sunk only if they contained contraband, and then only after safe passage had been provided for the crew and passengers.
