The soldados de cuera (English, "leather-jacket soldier")[1] served in the frontier garrisons of northern New Spain, the Presidios, from the late 16th to the early 19th century.[2] They were mounted and were an exclusive corps in the Spanish Empire. They took their name from the multi-layered deer-skin cloak they wore as protection against Indian arrows. When New Spain's visitador (inspector general) José de Gálvez organized the Portola Expedition, he was accompanied by a party of 25 soldiers, the "finest horsemen in the world, and among these soldiers who best earn their bread from the august monarch whom they serve".[1]
