Captain Charles Lemaire and the other members of the scientific mission joined Dardenne at the station by the Lake Moro on the 17th January 1899. The 7th February, they all set off overland in the direction of Lake Tanganyika. In July 1900, they took the return route to Belgium.
Other watercolours by Dardenne of the Lemaire scientific mission to Katanga are illustrated by Lynne Thornton, Les Africanistes, peintres-voyageurs, Paris, A.C.R. Edition, 1990.
