A group of unidentified Spanish sailors look down from the railings of the 4648 ton Spanish steam ship, Igotz Mendi, captured by the German armed merchant raider, SMS Wolf, on 10 November 1917, south of the Mauritius Islands in the Indian Ocean. Although the Igotz Mendi was a neutral ship, she was carrying 5000 tons of coal for the Royal Navy. A prize crew was placed on board and 1000 tons of coal was transferred to the raider as they sailed for the Cocos Islands. Both ships were painted grey and they travelled around the Cape of Good Hope and proceeded across the South Atlantic towards the Ilha da Trinade. During February 1918, the SMS Wolf and her prize sailed through the North Atlantic en route for Ruhleben via Iceland. Both ships had been badly damaged when the raider had coaled from the collier at sea in rough weather. Conditions for prisoners on board both ships were almost unbearable, the temperature reaching as low as minus 10 degree Celsius. Violent storms were encountered with huge waves that constantly washed over the decks. The two ships made the coast of Norway on 21 February 1918 but before reaching the safety of the port of Kiel the Igotz Mendi ran aground off the Danish coast in thick fog on 22 February 1918. A Danish gunboat retrieved the crew and prisoners on board but the Igotz Mendi remained firmly aground and was abandoned by the raider. This image is from a collection relating to the voyage of the German raider, SMS Wolf (II), and was taken by an unidentified crew member. Previously a freighter of the Hansa Line, with a gross tonnage of 5809 tons, she was launched as ‘Watchfels’ and was renamed SMS Wolf when she was fitted out as an auxiliary cruiser. She was prepared for her role as an armed merchant ship with an armament that included six 150mm guns, one 105mm gun, three 52mm guns, four torpedo tubes and carried 458 mines, to be placed in Allied territory throughout her journey. SMS Wolf was also provided with an innovative new weapon, the Friedrichshafen FF.33e two seater biplane, an aircraft that was used with deadly success to scout out new targets for attack or to elude enemy threats. The raider was relatively slow, with a top speed of only 11 knots but her bunkers held 8000 tons of coal, giving her a huge cruising range of 32000 nautical miles at eight knots. On 30 November 1916, SMS Wolf sailed from Kiel, Germany, with a complement of 348 sailors and commanded by Fregattenkapitän (Commander) Karl August Nerger. During the 451 days she was deployed in Allied territory around Australia, New Zealand, New Guinea, South Asia and Africa, she destroyed 35 trading vessels and two war ships, amounting to approximately 110000 tons. She returned to Kiel on 24 February 1918 with 467 prisoners of war and substantial quantities of rubber, copper, zinc, brass, silk, copra, cocoa and other essential materials to the German war effort. SMS Wolf, without any support, had made the longest voyage of a warship during the First World War. On her return to Germany, the Kaiser presented every crew member with the Iron Cross and Fregattenkapitän Nerger was awarded the highest German decoration, the Pour le Mérite.
