General Paul von Lettow-Vorbeck, who had served in German South West Africa and Kamerun, led the German military in GEA during World War I. His military consisted of 3,500 Europeans and 12,000 native Askaris and porters. Their war strategy was to harry the British/Imperial army of 40,000, which was at times commanded by the former Second Boer War commander Jan Smuts. One of Lettow-Vorbeck's greatest victories was at the Battle of Tanga (3–5 November 1914), where German forces defeated a British force more than eight times larger.
