_A third chapter of sea-raider history similar to those of the Möwe and Seeadler was revealed when the Spanish steamship Igotz Mendi, navigated by a German prize crew, ran aground on the Danish coast, Feb. 24, 1918, while trying to reach the Kiel Canal with a cargo of prisoners and booty. The next day the German Government announced that the sea-raider Wolf, which had captured the Igotz Mendi and ten other merchant vessels, with 400 prisoners, had successfully returned after fifteen months in the Atlantic, Indian, and Pacific Oceans. The story of the Wolf's operations, as gleaned by Danish and English correspondents from the narratives of released prisoners, is told below. Some of the most interesting passages were furnished by Australian medical officers who had been captured on the British steamer Matunga:_ The Wolf, a vessel of about 6,000 gross tonnage, armed with several guns and torpedo tubes, carried a seaplane, known as the Wolfchen, which was frequently used in the operations of the sea raider. On some days the seaplane made as many as three flights. The Wolf, apparently, proceeded from Germany to the Indian Ocean, laying minefields off the Cape, Bombay, and Colombo. Early in February, 1917, she captured the British steamship Turritella, taking off all the officers and putting on board a prize crew which worked the vessel with her own men. In every case of capture, when the vessel was not sunk at once, this procedure was adopted. The Wolf transferred a number of mines to the Turritella, with instructions that they should be laid off Aden. A few days later the Turritella encountered a British warship, whereupon the prize crew, numbering twenty-seven, sank the Turritella, and were themselves taken prisoner. Three weeks later the Wolf overhauled the British steamer Jumna. The Wolf thought that the British vessel was about to ram her, and the port after-gun was fired before it was properly trained, killing five of the raider's crew and wounding about twenty-three others. The Jumna remained with the Wolf for several days, after which her coal and stores were transferred to the raider, and she was sunk with bombs. The next vessels to be captured and sunk were the British steamships Wordsworth and Dee.
