The Battle of Fort Duquesne was a British assault on the French-controlled Fort Duquesne (later the site of Pittsburgh) on 14 September 1758, during the French and Indian War. This force was out-maneuvered, surrounded, and largely destroyed by the French and their native allies led by François-Marie Le Marchand de Lignery.
