The military (and social) history of Pensacola Bay commences in 1558, when Philip II, of Spain, commissioned Luis de Valesca, viceroy of New Spain, to undertake the settlement of Florida. After a preliminary survey Valesca, in the summer of 1559, sent 1500 soldiers and settlers to make a beginning at Pensacola Bay, this body of water having been adjudged the best roadstead and the most favorable for the support of human life on the Gulf Coast. A tentative settlement was established, but for some reason the site did not please the expedition and its leaders attempted unsuccessfully to find a better one. The winter that followed and the next summer were filled with privation and the colony became much reduced in numbers. During the second summer most of the settlers went with Angel de Villafane to Santa Elena, Port Royal Sound, south on the Atlantic coast (South Carolina, to-day) and the remainder was recalled by Philip II, who thereupon decreed that no further effort should be made to settle the west coast of Florida, a royal promulgation which circumstance and lack of incentive to the contrary conspired to make effective for more than a century. If one accepts this abortive expedition as the beginning of settlement in Florida then Pensacola is the oldest point of European residence in the United States, antedating St. Augustine by seven years. The Spaniards did not regard La Salle’s effort at colonization at the mouth of the Mississippi River with favor and were not at all displeased at his misfortunes. To forestall other efforts of the French they undertook a survey of the coast and established a colony at Pensacola in the last years of the Seventeenth Century. This was the beginning of Pensacola of to-day.

The Frenchmen asked for permission to disembark his forces. His request was refused and he then sailed along the coast until he found a landing to his liking near the present-day Biloxi, Mississippi. The governor of Pensacola at this time--and the first governor of the colony--was Don Andre D’Arriola. The fort was named San Carlos de Barrancas. There came in 1719 a war against Spain in which France and England were allies opposed to her. The French thereupon sent in this year M. de Serigny with a sufficient force to take possession of Pensacola which was valuable to the French on account of its proximity to Louisiana and its accessibility to the West India Islands. The expedition was entirely successful as, after an attack by land by 700 Canadians, the commander of the Spanish garrison, Don John Peter Matamoras, surrendered with the honors of war.
