 There, with great difficulty, the expedition carried the two boats, with the aid of steam engines and mules, to the edge of Lake Tanganyika.They captured one ship, the "Kigani", and named her "Fifi"; they also sank the "Hedwig von Wissman", but did not engage the formidable "Graf von Götzen", which remained dominant on the lake until she was scuttled in the wake of an Anglo-Belgian attack overland on German positions.The scuttled ship "Graf von Götzen" was raised and now operates on the lake as the MV "Liemba".
