When Governor Melchor Feliu closed the extensive and complicated operation of evacuating Spanish residents from St. Augustine on February 5, 1764, he reported that in order to provide for looking after certain properties of the king, and to dispose of many horses running in the woods, he had left seven soldiers and an interpreter there. One of these was a militiaman, Luciano de Herrera, whose family had long been resident in the colony.
