Paul von Lettow-Vorbeck, German general (d. 1964)
Paul Emil von Lettow-Vorbeck (20 March 1870 – 9 March 1964), also called the Lion of Africa (German: Löwe von Afrika), was a general in the Imperial German Army and the commander of its forces in the German East Africa campaign. For four years, with a force of about 14,000 (3,000 Germans and 11,000 Africans), he held in check a much larger force of 300,000 British, Indian, Belgian, and Portuguese troops.
Essentially undefeated in the field, Lettow-Vorbeck was the only German commander to successfully invade a part of the British Empire during the First World War. His exploits in the campaign have been described by Edwin Palmer Hoyt as "the greatest single guerrilla operation in history, and the most successful."
