Mr. Thompson did not see any torpedo fired at the Orduna by the German submarine, and was unable to give first-hand testimony that the Orduna had been fired on without notice. It was determined, however, that the report of Mr. Thompson justified the Government in making an investigation. Accordingly, Secretary Lansing wrote a letter to Secretary McAdoo, requesting that his department undertake the investigation, which will probably be intrusted to the Collector of Customs at New York. At the State Department it was said that the attention of the German Government had not been called to the charge that the Orduna was fired on by a German submarine without warning. Any action of that sort, if taken, will follow the investigation which is now ordered. NEBRASKAN'S CASE _Ambassador Gerard on July 15 formally transmitted to Washington Germany's admission of liability and expression of regret for the attack by a German submarine on the American steamer Nebraskan._ _Secretary Lansing's announcement of the German memorandum follows:_ Ambassador Gerard has telegraphed to the Department of State the following memorandum from the German Foreign Office relative to the damaging of the American steamer Nebraskan by a German submarine: "The German Government received from newspaper reports the intelligence that the American steamer Nebraskan had been damaged by a mine or torpedo on the southwest coast of Ireland. It therefore started a thorough investigation of the case without delay, and from the result of the investigation it has become convinced that the damage to the Nebraskan was caused by an attack by a submarine. "On the evening of May 25 last the submarine met a steamer bound westward without a flag and no neutral markings on her freeboard, about 65 nautical miles west of Fastnet Rock. No appliance of any kind for the illumination of the flag or markings was to be seen. In the twilight, which had already set in, the name of the steamer was not visible from the submarine. Since the commander of the submarine was obliged to assume from his wide experience in the area of maritime war that only English steamers, and no neutral steamers, traversed the war area without flag and markings, he attacked the vessel with a torpedo, in the conviction that he had an enemy vessel before him. Some time after the shot the commander saw that the vessel had in the meantime hoisted the American flag. As a consequence, he, of course, refrained from any further attack. Since the vessel remained afloat, he had no occasion to concern himself further with the boats which had been launched.
