his whole party from cold and hunger. By astronomical observation he found that he was in the latitude of the bay of San Francisco; but between him and the valleys of California was a snow-clad range of mountains, which the Indians declared no man could cross, and over which no reward could induce them to attempt to guide him. Frémont undertook the passage without a guide, and accomplished it in forty days, reaching Sutter's Fort, on the Sacramento, early in March, with his men reduced almost to skeletons, and with only thirty-three out of sixty-seven horses and mules remaining. Resuming his journey on 24 March, he crossed the Sierra Nevada through a gap, and after another visit to Great Salt lake returned to Kansas through the South pass in July, 1844, having been absent fourteen months. The reports of this expedition occupied in their preparation the remainder of 1844. Frémont was given the double brevet of 1st lieutenant and captain in January, 1845, at the instance of Gen. Scott, and in the spring of that year he set out on a third expedition to explore the great basin and the maritime region of Oregon and California. After spending the summer in exploring the watershed between the Pacific and the Mississippi, he encamped in October on the shore of the Great Salt lake, and after crossing the Sierra Nevada with a few men, in the dead of winter, to obtain supplies, left his party in the valley of the San Joaquin while he went to Monterey, then the capital of California, to obtain from the Mexican authorities permission to proceed with his exploration. This was granted, but was almost immediately revoked, and Frémont was ordered to leave the country without delay. Compliance with this demand was impossible, on account of the exhaustion of Frémont's men and his lack of supplies, and it was therefore refused. The Mexican commander, Gen. José Castro, then mustered the forces of the province and prepared to attack the Americans, who numbered only sixty-two. Frémont took up a strong position on the Hawk's peak, a mountain thirty miles from Monterey, built a rude fort of felled trees, hoisted the American flag, and, having plenty of ammunition, resolved to defend himself. The Mexican general, with a large force, encamped in the plain immediately below the Americans, whom he hourly threatened to attack. On the evening of the fourth day of the siege Frémont withdrew with his party and proceeded toward the San Joaquin. The fires were still burning in his deserted camp when a messenger arrived from Gen. Castro to propose a cessation of hostilities. Frémont now made his way northward through the Sacramento valley into Oregon without further trouble, and near Tlamath lake, on 9 May, 1846, met a party in search of him with despatches from Washington, directing him to watch over the interests of the United States in California, there being reason to apprehend that the province would be transferred to Great Britain, and also that Gen. Castro intended to destroy the American settlements on the Sacramento. He promptly returned to California, where he found that Castro was already marching against the settlements. The settlers flocked to Frémont's camp, and in less than a month he had freed northern California from Mexican authority. He received a lieutenant-colonel's commission on 27 May, and was elected governor of California by the American settlers on 4 July. On 10 July, learning that Com. Sloat, commander of the United States squadron on that coast, had seized Monterey, he marched to join him, and reached that place on 19 July, with 160 mounted riflemen. About this time Com. Stockton arrived at Monterey with the frigate “Congress” and took command of the squadron, with authority from Washington to conquer California. At his request Frémont organized a force of mounted men, known as the “California battalion,” of which he was appointed major. He was also appointed by Com. Stockton military commandant and civil governor of the territory, the project of making California independent having been relinquished on receipt of intelligence that war had begun between the United States and Mexico. On 13 Jan., 1847, Frémont concluded with the Mexicans articles of capitulation, which terminated the war in California and left that country permanently in the possession of the United States. Meantime Gen. Stephen W. Kearny, with a small force of dragoons, had arrived in California. A quarrel soon broke out between him and Com. Stockton as to who should command. Each had instructions from Washington to conquer and organize a government in the country. Frémont had accepted a commission from Com. Stockton as commander of the battalion of volunteers, and had been appointed governor of the territory. Gen. Kearny, as Frémont's superior officer in the regular army, required him to obey his orders, which conflicted with those of Com. Stockton. In this dilemma Frémont concluded to obey Stockton's orders, considering that he had already fully recognized that officer as commander-in-chief, and that Gen. Kearny had also for some time admitted his authority. In the spring of 1847 despatches from Washington assigned the command to Gen Kearny, and in June that officer set out overland for the United States, accompanied by Frémont, whom he treated with deliberate disrespect throughout the journey. On the arrival of the party at Fort Leavenworth, on 22 Aug., Frémont was put under arrest and ordered to report to the adjutant-general at Washington, where he arrived on 16 Sept., and demanded a speedy trial. Accordingly a court-martial was held, beginning 2 Nov., 1847, and ending 31 Jan., 1848, which found him guilty of “mutiny,” “disobedience of the lawful command of a superior officer,” and “conduct to the prejudice of good order and military discipline,” and sentenced him to be dismissed from the service. A majority of the members of the court recommended him to the clemency of President Polk. The president refused to confirm the verdict of mutiny, but approved the rest of the verdict and the sentence, of which, however, he remitted the penalty. Notwithstanding this, Frémont at once resigned his commission, and on 14 Oct., 1848, set out on a fourth expedition across the continent, at his own expense, with the object of finding a practicable passage to California by way of the upper waters of the Rio Grande. With thirty-three men and 120 mules he made his way through the country of the Utes, Apaches, Comanches, and other Indian tribes then at war with the United States. In attempting to cross the great Sierra, covered with snow, his guide lost his way, and Frémont's party encountered horrible suffering from cold and hunger, a portion of them being driven to cannibalism. All of his animals and one third of his men perished, and he was forced to retrace his steps to Santa Fé. Undaunted by this disaster, he gathered another band of thirty men, and after a long search discovered a secure route by which he reached the Sacramento in the spring of 1849. He now determined to settle in California, where, in 1847, he had bought the Mariposa estate, a large tract of land containing rich gold-mines. His title to this estate was contested, but after a long litigation it was decided in his favor in 1855 by the supreme
