The vast military campaigns in Africa during World War I were among the most ambitious of the Great War. Many histories, however, have regarded these campaigns as side-shows to the war on the Western Front. World War One in Africa looks afresh at the impact of the strategy of the German and Allied campaigns, and at the great rivalry between General Jan Christian Smuts, who took on the German forces in East Africa, and General Lettow-Vorbeck, celebrated as the only German general to occupy British territory and whose troops finished the war undefeated. Using primary material from British and South African archives, this book is a detailed study of the giants of the campaign, and the battles which would shape the outcome of the Great War as well as the future of the African continent and the British Empire.
