The Marine Corps Base at San Diego is surrounded by evidences of the Spanish heritage of southern California. Among the more conspicuous are the euphonious place names found everywhere , including the name San Diego itself, and the picturesque architecture that may be seen, not only in the city, but also in the permanent buildings of the Marine Corps post. This is a natural consequence of the fact that California was a Spanish possession for nearly three centuries. The region was claimed for Spain in 1542 by Juan Rodriquez Cabrillo, a Portuguese navigator in the services of Charles V and the first white man to see San Diego Bay. It remained under Spanish control until 1821, when Mexico won her independence from Spain. Thereafter, for about a quarter of a century, California was claimed by Mexico.
Geography and the westward expansion of the United States now brought the Marines into their first contact with San Diego. The town was seized by a landing party of seamen and Marines from the USS Cyane on 29 July 1846, shortly after war had broken out between the United States and Mexico. It was in this operation that the Stars and Stripes was first raised in southern California. Marines were also among the reinforcements sent early the following December to assist Brigadier General Stephen W. Kearny, USA, and his dragoons in completing the final portion of their march from Santa Fe, New Mexico, to San Diego/ Despite the harassment of Andres Pico’s lancers, Kearny succeeded in reaching San Diego on 12 December 1846. Hostilities in the California theater of operations ceased about a month later; and when the Treaty of Guadalupe-Hidalgo formally ended the war in 1848, Mexico ceded to the United States a large block of territory that included California.
Geography – an important element, as we have noted, in the foregoing events – has been a constant factor in the working out of San Diego’s destiny with respect to the Marine Corps. Only 12 miles north of the Mexican border and possessed of an excellent harbor, the city readily recommended itself to the strategic eye as an expeditionary base on the west coast when the need for such a base became evident in the early twentieth century. San Diego was not only convenient to the Pacific approaches of Latin America, where it was apparent that trouble could be expected at intervals, but it could also serve advantageously as a port of embarkation for Hawaii and the Par East* Concrete action toward establishing a base there, however, awaited some precipitating event. Mexican political Instability was to provide the catalyst that returned the Marines to San Diego for the first time since the Mexican War and subsequently caused a permanent Marine Corps post to be established there.
