An American war correspondent, James F. J. Archibald, a passenger on the liner _Rotterdam_ from New York, who was suspected by the British authorities of being a bearer of dispatches from the German and Austrian Ambassadors at Washington, to their respective Governments, was detained and searched on the steamer's arrival at Falmouth on August 30, 1915. A number of confidential documents found among his belongings were seized and confiscated, the British officials justifying their action as coming within their rights under English municipal law. The character of the papers confirmed the British suspicions that Archibald was misusing his American passport by acting as a secret courier for countries at war with which the United States was at peace. The seized papers were later presented to the British Parliament and published. In a bulky dossier, comprising thirty-four documents found in Archibald's possession, was a letter from the Austro-Hungarian Ambassador at Washington, Dr. Dumba, to Baron Burian, the Austro-Hungarian Foreign Minister. In this letter Dr. Dumba took "this rare and safe opportunity" of "warmly recommending" to the Austrian Foreign Office certain proposals made by the editor of a Hungarian-American organ, the "Szabadsag," for effecting strikes in plants of the Bethlehem Steel Company and others in the Middle West engaged in making munitions for the Allies.
