The River War is Winston S. Churchill's detailed account of Britain's military campaign against the Mahdist forces in Sudan (1896-1899). Combining firsthand observations with historical analysis, Churchill explores the politics, strategy, and brutal realities of colonial warfare as British and Egyptian forces, led by General Kitchener, seek to reclaim Sudan. With vivid descriptions of battles, including the pivotal Battle of Omdurman, and reflections on imperialism, this work remains a compelling study of 19th-century military conflict and geopolitics.
