After taking possession of Monterey, Commodore Sloat despatched a courier to the commanding-general of California, summoning him to surrender every thing under his control in the country, and assuring him of protection if he should comply. The general refused, and said he would defend the country as long as he could reckon on a single person to join his cause. A summons to surrender was also sent to the governor of Santa Barbara, but no answer was returned. Orders were despatched to Commander Montgomery, in the Portsmouth, at San Francisco, directing him to take possession of the Bay of San Francisco, and hoist the flag of the United States at Yerba Buena. On the 9th of July, the day after the receipt of his orders, Montgomery landed at Yerba Buena with seventy seamen and marines, and hoisted the American flag in the public square, amid the cheers of the people. A proclamation was then posted to the flag staff, and Montgomery addressed the people. The greater part of the seamen and marines then returned to the ship, leaving Lieutenant H. B. Watson with a small guard, formally installed as military occupant of the post. Thirty-two of the male residents of Yerba Buena were enrolled as a volunteer corps, choosing their own officers. Lieutenant Missroon was despatched with a small party of these volunteers to reconnoitre the Presidio and fort. He returned the same day, and reported that the Presidio had been abandoned, and that the fort, seven miles from the town, was dilapidated and mounted only a few old pieces of cannon. The flag of the United States had been displayed from its ramparts. On the 11th, Montgomery informed Commodore Sloat that the flag of the United States was then flying at Yerba Buena, Sutter's Fort, on the Sacramento, Bodega, on the coast, and Sonoma. The inhabitants of these places appeared to be satisfied with the protection afforded them by the Americans. On the 13th of July, Commodore Sloat sent a flag to the foreigners of the pueblo of San Jose, about seventy miles from Monterey, in the interior, and appointed a justice of the peace in place of the alcaldes. On the 15th, Commodore Stockton arrived at Monterey, in the frigate Congress; and Commodore Sloat being in bad health, the command devolved upon Stockton, and Sloat returned home. The operations of Commodore Stockton, from the 23d of July to the 28th of August, 1846, have been rapidly sketched by himself in his despatches to the secretary of the navy. From these we condense a short account.
