German Colonial collectors should find the following information useful:

The East African Campaign was a series of battles and guerrilla actions which started in German East Africa and ultimately affected portions of Mozambique, Northern Rhodesia, British East Africa, Uganda and the Belgian Congo. The campaign was effectively ended in November 1917. However, the Germans entered Portuguese East Africa and continued the campaign living off Portuguese supplies.
The strategy of the German colonial forces, led by Lieutenant Colonel (later Generalmajor) Paul Emil von Lettow-Vorbeck, was to drain and divert forces from the Western Front to Africa. His strategy failed to achieve these results after 1916, as mainly Indian and South African forces, which were prevented by colonial policy from deploying to Europe, conducted the rest of the campaign.
Nevertheless, the Germans fought for the whole of World War I, receiving word of the Armistice on 14 November 1918 at 7:30 a.m. Both sides waited for confirmation, and the Germans formally surrendered on 25 November. German East Africa ultimately became two League of Nations Class B Mandates, Tanganyika Territory of the United Kingdom and Ruanda-Urundi of Belgium, while the Kionga Triangle became a mandate of Portugal.
