War of the Castilian Succession
Alonso de Cárdenas served the Catholic Monarchs during the War of the Castilian Succession. One of the captains under his command was Gonzalo Fernández de Córdoba, also known simply as the "Gran Capitan" for his considerable military exploits throughout Spain's European empire. After the Battle of Albuera, Alonso singled the Gran Capitan out for praise stating that he had always seen the captain leading his troops from the front, a fact he was sure of due to the splendor of his armor.
