A party of Fremont's men rode down to Sonoma, where there was a Mission, and also a presidio with a few cannon in charge of General Vallejo. These men captured the place and sent Vallejo and three other prisoners back to Fremont's camp. Then the independent Americans concluded to have a new republic of their own, and a flag also. So they made the famous "Bear-flag" of white cloth, with a strip of red flannel sewed on the lower edge, and on the white they painted in red a large star and a grizzly bear, and also the words "California Republic." They then raised the flag over the Bear-flag Republic. Many Americans joined their party, but when the American flag went up at Monterey, the stars and stripes replaced the bear-flag. At this time the United States and Mexico were at war on account of Texas, and Commodore Sloat was in charge of the warships on the Pacific Coast. The commodore had been told to take Alta California, if possible; so, sailing to Monterey, he raised the stars and stripes there in July, 1846, and ended Mexican power forever. The American flag flew at the San Francisco Presidio two days later, and also at Sonoma, Sutter's Fort, or wherever there were Americans. The flag was greeted with cheers and delight. Then Commodore Sloat turned the naval force over to Stockton and returned home, leaving all quiet north of Santa Barbara. Commodore Stockton sent Fremont and his men to San Diego and, taking four hundred soldiers, went himself to Los Angeles, where the native Californians and Mexicans were determined to fight against the rule of the United States. General Castro and his men and Governor Pico, the last of the Mexican governors, were driven out of the country. Stockton then declared that Upper and Lower California were to be known as the "Territory of California." In less than a month, however, the Californians in the south gathered their forces again and took Los Angeles. General Kearny was sent out with what was called the "army of the west," to assist Fremont and Stockton in settling the trouble. Peace was declared after several battles, and Kearny acted as governor of the new territory, displacing Fremont. At last, by the treaty which closed the Mexican war in 1848 Alta California became the property of the United States, and Lower California was left to Mexico. From that time there was peace and quiet, and before long the discovery of gold brought the new territory into great importance. The rush to the gold mines brought thousands of men, and as no government had been provided for the territory, Governor Riley in '49 called a convention to form a plan of government. This Constitutional Convention of delegates from each of California's towns met in Monterey. The constitution there drawn up lasted for thirty years, and under it our great state was built up. It declared that no slavery should ever be allowed here, and settled the present eastern boundary line.
