Nadezhda Andreyevna Durova (Russian: ????´??? ?????´???? ??´????) (September 17, 1783 – March 21, 1866), also known as Alexander Durov, Alexander Sokolov and Alexander Andreevich Alexandrov, was a woman who, while disguised as a man, became a decorated soldier in the Russian cavalry during the Napoleonic wars.
She was the first known female officer in the Russian military.
Her memoir, The Cavalry Maiden, is a significant document of its era because few junior officers of the Napoleonic wars published their experiences, and because it is one of the earliest autobiographies in the Russian language.
