 On 9 February 1916, the German lake boat (sister vessel of the larger on Lake Nyasa) appeared off Lukuga to investigate the disappearance of "Kingani".After a chase, Spicer-Simson's flotilla sank "Hedwig von Wissmann".The capture of "Kingani" and the sinking of "Hedwig von Wissmann" greatly weakened German naval power on Lake Tanganyika.
