MONCLOVA, CONDE DE
MONCLOVA, CONDE DE (?–?). Don Melchor Portocarrero Lasso de la Vega, Count of Monclova, became viceroy of New Spain on November 30, 1686. As a member of the Council of the Indies, he had come to America with a directive from that body to rid Texas of the French menace caused by La Salle's settlement at Fort St. Louis. Monclova arrived at Veracruz on September 13, 1686. He first sent out the expedition under Martín de Rivas and Antonio de Iriarteqqv that discovered the wreck of a French vessel in Matagorda Bay but failed to find the French colony. Two other unsuccessful maritime expeditions were sent out during the two years of his administration. The third land expedition of Alonso De León discovered the French, but the location of La Salle's colony was not discovered until after the close of Monclova's administration in November 1688, when he went to Peru as viceroy. Monclova was commonly known as Brazo de la Plata because of his false arm. The city of Monclova, for a time a contestant to be the capital of Coahuila and Texas, was probably named for him.
