In pursuance of this plan, an American squadron appeared before the fort of Monterey, on the Pacific, in Alta California, on the 7th of July, two months after the first shots of warfare on the Rio Grande. This Monterey must not be confounded with the other Mexican town of the same name. The Mexicans evacuated the place with the few soldiers who constituted the garrison. On the same day two hundred and fifty seamen landed, and took possession, and hoisted the American flag. This course was in pursuance of instructions from the Secretary of the Navy to the commander of the Pacific squadron, thus expressed in a letter, written as early as June 24, 1845: "It is the earnest desire of the President to pursue the policy of peace, and he is anxious that you, and every part of your squadron, should be assiduously careful to avoid any act which could be construed into an act of aggression. Should Mexico, however, be resolutely bent on hostilities, you will be mindful to protect the persons and interests of citizens of the United States, and should you ascertain beyond a doubt that the Mexican government has declared war against us, you will employ the force under your command to the best advantage. The Mexican ports on the Pacific are said to be open and defenceless. If you ascertain with certainty that Mexico has declared war against the United States, you will at once blockade or occupy such ports as your force may admit."

MONTEREY, MEXICO.

Other ports were taken with equal ease; and the navy having joined forces with the army of Colonel Fremont, the Americans entered the capital of Alta California, on the 13th of August, and took possession of the government house without a show of opposition, issuing at once a proclamation announcing the conquest of the department.

Meanwhile General Taylor, greatly reinforced by volunteer troops sent from the United States, advanced into the interior of the country though the state of Nueva Leon, bordering upon the Rio Grande and the Gulf of Mexico, and approached its capital, the other Monterey. It lies at the eastern base of a range of hills, in a valley of great fertility, which is capable of supporting a large population. The main road from the Rio Grande to the city of Mexico leads from the east through a cultivated country, directly through the city, and continues by a pass through the Sierra, by Saltillo, and on to a desert region between Saltillo and San Luis de Potosi. A rivulet, the San Juan de Monterey, rises in this pass and crosses the valley. Monterey stands on the northern bank of this rivulet, and extends along the stream. At the time of the battle it contained about two thousand inhabitants. A spur of the mountain Sierra juts out above the city to the west, and on this is perched the picturesque Obispado Viejo, or Old Palace, built by a bishop of the last century for his pleasure-seat.
