 The Spanish Navy entered the American Revolutionary War with a system of tactics devised by him, "Teniente de navío de la Real Armada", and expounded in "Rudimentos de Táctica Naval para Instrucción de los Officiales Subalternos de Marina", printed at Madrid in 1776, dedicated to King Charles III.Despite bearing some evidence of the influence of Paul Hoste and Sébastien Morogues, this is a text book for junior officers, though it could clearly have been read with profit by all alike.In common with the French writers, Mazarredo said very little about fighting the enemy.
