It was not until early in August that the _Deutschland_, which had made two trips to the United States as a commercial submarine in 1916, left Germany for American waters. Her operations were mainly far out at sea or in Canadian waters, and she never came within 200 or 300 miles of the United States coast. Renamed the U-155, the _Deutschland_ began her activities on this expedition on August 27, 1918, when she attacked the American steamship _Montoso_ almost in mid-Atlantic. It was at night, about 9 o'clock, when the _Montoso_ and the _Rondo_ and _Ticonderoga_, which were with her, opened fire. The submarine fired several shots, but the guns of our vessels drove it off. Five days later the _Deutschland_ attacked the _U. S. S. Frank H. Buck_, opening fire with two six-inch guns. Firing first with its 3-inch forward gun, then putting into action its six-incher, the _Buck_ made a vigorous reply. Her shots were falling close to the "sub," but enemy shrapnel was bursting above the vessel and falling on deck. The _Buck_ reported that one of her shots apparently hit right at the stern of the U-boat and another forward of the conning tower, under the water line. The submarine then disappeared. She seemed to have been damaged, but not enough to put her out of commission, for on September 2nd she sank the Norwegian steamer _Shortind_ and on the 7th chased and shelled the British steamship _Monmouth_. Five days later she torpedoed the Portuguese steamer _Leixoes_, three of the crew being lost, one going down with the ship and two dying of cold and exposure in the lifeboats. September 13th was an unlucky day for the _Deutschland_, for in a gunfire contest with the armed British merchantman _Newby Hall_, she was struck by a shell which exploded and temporarily put out of action her forward gun. For the next week she seems to have devoted her attention to mine-laying, off Halifax and the Nova Scotian coast. Then she sank a small steam trawler, the _Kingfisher_, and on Sept. 29th unsuccessfully attacked the British steamer _Reginolite_. On October 3 and 4, she sank the Italian steamship _Alberto Treves_ and the British schooner _Industrial_. At 10 a. m., Oct. 12th, the _Deutschland_ attacked the American steamship _Amphion_, formerly the German _Köln_. Her second shot carried away the steamer's wireless. Then ensued a gunfire contest that lasted more than an hour, the submarine firing some 200 shots and the _Amphion_ 72. The _Amphion_ was hit time and again, her lifeboats were riddled, and her super-structure damaged, but she gradually drew off and the U-boat abandoned the chase.
