The Action of Tambo Nuevo, also known as Hazaña de los Tres Sargentos was a successful cavalry raid carried out between 23 and 25 October 1813, during the second Upper Peru campaign of the Argentine War of Independence, by a small detachment of Dragones of the Army of the North. The targets were the headquarters of royalist Colonel Saturnino Castro at Yocalla, and later a forward outpost on Tambo Nuevo.
