Bernardino de Mendoza (c. 1540 – 3 August 1604) was a Spanish military commander, diplomat and writer on military history and politics. Biography Bernardino de Mendoza was born in Guadalajara, Spain around 1540, as the son of Don Alonso Suarez de Mendoza, third Count of Coruña and Viscount of Torija, and Doña Juana Jimenez de Cisneros. In 1560, he joined the army of Philip II and for more than 15 years fought, he in the Low Countries under the command of Fernando Álvarez de Toledo, Duke of Alba. During that period, he participated in the Spanish military actions at (among others) Haarlem, Mookerheyde and Gembloux. In 1576, he was appointed a member of the military Order of St. James (Orden militar de Santiago) in recognition of those military achievements.
