On January 30th the German Government announced its blockade of all Allied coasts and stated that all shipping within these waters, except on special lanes, would be sunk without notice. Germany challenged the whole world to stay off of the ocean. President Wilson broke diplomatic relations immediately and ordered Ambassador Gerard to return home. Gerard called at the Foreign Office for his passports and said that he desired to leave at once. Zimmermann informed him that as soon as the arrangements for a train could be made he could leave. Zimmermann asked the Ambassador to submit a list of persons he desired to accompany him. The Ambassador's list was submitted the next day. The Foreign Office sent it to the General Staff, but nearly a week passed before Gerard was told he could depart and then he was instructed that the American consuls could not accompany him, but would have to take a special train leaving Munich a week or two later. American correspondents, who expressed a desire to accompany the Ambassador, were refused permission. In the meantime reports arrived that the United States had confiscated the German ships and Count Montgelas, Chief of the American division of the Foreign Office, informed Gerard the American correspondents would be held as hostages if America did this. Gerard replied that he would not leave until the correspondents and all other Americans were permitted to leave over any route they selected. Practically all of the correspondents had handed in their passports to the Foreign Office, but not until four hours before the special train departed for Switzerland were the passports returned. When Gerard asked the Foreign Office whether his passports were good to the United States the Foreign Office was silent and neither would the General Staff guarantee the correspondents a safe conduct through the German submarine zone. So the only thing the Ambassador could do was to select a route via Switzerland, France and Spain, to Cuba and the United States.
