General Paul von Lettow-Vorbeck’s East African Campaign was a conventional war of movement. Lettow based his operations on the military principles deduced from his thorough German military education and oversea deployments to China and German South West Africa. Upon assignment to German East Africa, he sought to convert the colony’s protectorate force from a counterinsurgency force to a conventional military force. His conventional strategy succeeded early in the war, especially at the Battle of Tanga in October 1914. However, his strategy failed as the war in East Africa intensified. He suffered a calamitous defeat at the Battle of Mahiwa in November 1917, and the heavy losses forced Lettow to adopt the counterinsurgency tactics of the colonial protectorate force.
