Political map of Sub-Saharan Africa 4 February 1915 (Early Victories of the Schutztruppe): The Maritz rebellion forced South Africa to postpone its invasion of German South West Africa (South West Africa campaign), allowing the Germans to launch counteroffensives into South Africa (Battle of Kakamas) and Angola (German campaign in Angola). Meanwhile the Germans were faring even better in East Africa, inflicting humiliating defeats on the British at Tanga (Battle of Tanga) and Kilimanjaro (Battle of Kilimanjaro).
