the advantage of the Allies, who cut off the railway link in July 1916 and threatened to isolate Kigoma completely. This led the German naval commander on the lake, Gustav Zimmer, to abandon the town and head south. In order to avoid the ship falling into Allied hands, General Lettow-Vorbeck ordered that Goetzen be scuttled. The task was given to the three engineers from Meyer Werft who had travelled with the disassembled ship to Lake Tanganyika in order to supervise its re-assembly. The engineers decided on their own that they would try to facilitate a later salvage; they loaded the ship with sand and covered all engines with a thick layer of grease before sinking her carefully on 26 July, in a depth of near the banks of the Katabe Bay (Belgian designation: Baie de l’éléphant; British designation: Bangwe Bay) at the position . Salvage and recommissioning Johann Ludwig Wall, a Swede working for the Belgians, salvaged the ship in 1918. He initially had divers remove large quantities of material. Then he filled the holds with empty barrels and passed cables under the ship to two 375 t barges that the "Compagnie des Chemins de fer du Congo Supérieur aux Grands Lacs Africains" had purpose-built for the task and positioned on each side of the wreck. By the end of June 1919, the Belgians had succeeded in lifting the ship up to her gunwales by winding in the cables. Then in mid-September the Belgians floated the semi-submerged vessel to Kigoma. There she settled in water deep. The water was shallow enough that her superstructure extended above the surface of the lake. Early in 1920, a storm moved the vessel, sinking her at Point Lusana in . The photos of Kigoma Bay that Homer L. Shantz made in mid-February 1920 show no sign of the ship. In 1921 the British took control of Kigoma. They then took until 16 March 1924 to raise the ship again. The British found that the engines and boilers were still usable and so they decided to rehabilitate the ship. On 16 May 1927 the ship went back into service under the name Liemba. Mary Katherine Scott, the wife of the chief secretary and acting governor Sir John Scott, launched Liemba for the Tanganyika Railways and Port Service. The pure conversion costs amounted to about £30,000 sterling. Salvage had cost £20,000, and infrastructure £28,000. The Germans
