René Jacques Adolphe Prioux (11 April 1879 – 16 June 1953) was a general of the French Army who served in both world wars. A cavalry officer of great talent, Prioux rapidly rose through the officer ranks and commanded the Cavalry Corps of the First Army during the Battle of Belgium in May 1940. He was captured by the Germans and spent two years as a prisoner of war. Repatriated in 1942, Prioux came to be seen as a strong supporter of the Vichy regime and was consequently removed from a position of authority in the French Army by Charles de Gaulle, the leader of the Free French, after the landings in French north Africa by U.S. and British forces in November 1942.
