Upon reaching the vicinity of Monterey, Fremont was ordered out of the country by the Mexican authorities. Intrenching himself on a hill, back of Monterey, he hoisted the American flag, and bade defiance to the order. Finding the Mexicans would not attack him, he marched northward up the Sacramento Valley as far as Klamath Lake unmolested, save by Indians with whom he had several combats. At this place, Fremont was overtaken by a messenger who had come across Mexico with despatches from the Government. It is thought Fremont was unofficially advised to make the most of any opportunity that should present itself. At any rate, he seems to have thought the time was come for him to drop his character of explorer and turn his presence in California to account. He therefore set out at once for Sutter's Fort, where he could be near the American settlers, who were living in the lower part of the valley or about the Bay of San Francisco. Fremont thus became the rallying-point for his countrymen in California, and their protector. [Illustration: CALIFORNIA INDIANS AND TULE HUTS, SACRAMENTO VALLEY.] This was in June, 1846. Rumors of war were now flying thick and fast. The Californians were quarrelling among themselves over questions then dividing the Mexican nation. The American settlers were thrown into more or less alarm by the threats made to drive them from the country. We had ships-of-war at San Francisco and Monterey, but their commanders hesitated to act until it was known the two nations were at war. The settlers put an end to all indecision by raising the flag of revolt themselves. On the 14th these settlers seized Sonoma, a military post lying to the north of San Pablo Bay. They immediately proclaimed California an independent republic. Upon this Fremont put himself at their head. He marched first to Sonoma, and next to the Presidio of San Francisco, whose garrison fled at his approach. By these prompt acts all the country lying north of the Bay of San Francisco fell into the hands of the insurgents. These events were followed by the raising of an American flag over Monterey, July 7, by Commodore Sloat. The same thing was done by his order at Yerba Buena and Sonoma. As soon as he heard of it, Fremont also hoisted the flag at Sutter's Fort. He then marched for Monterey, where the ships Savannah, Congress, Cyane, and Levant were lying with their guns commanding the town. An English line-of-battle ship was also anchored in the basin of Monterey, and another at Yerba Buena. With whatever intentions they had come, they had arrived just too late. In this manner what is known as the Bear Flag Revolution, from the settlers' having borne a bear on their standard, began and ended with Fremont for its central figure. Without him it would never have been possible. But for him the conquest would not have come when it did, but it would have come.
