General Castro sent one of his captains, with quite a force to destroy the Americans, but the officer changed his mind when he found himself in the neighborhood of the detested invaders. Fremont pursued him for nearly a week, and captured much of his stock and property, but the Mexican was so skilful in retreating that he could not be brought to bay and Fremont returned to Sonoma.
The little force under Fremont now became the rallying point for the American settlers, and before long the Captain had several hundred under his command. Leaving a garrison at Sonoma, he marched to Sutter's Fort, which was placed under military rule, and then made his way toward Monterey with the purpose of capturing that town. On his arrival, however, he found the place had already been taken by Commodore Sloat and the American squadron. The Commodore leaving shortly after, Commodore Stockton succeeded him.
While at Sonoma, Fremont and his comrades had declared the independence of California and adopted the Bear Flag, which was proffered to Commodore Sloat and the Star Spangled Banner hoisted over the camp.
As the Mexican General, Castro, was known to be at Los Angeles, Fremont asked for and obtained a ship on which his force was taken to San Diego. Then with a much inferior force, he set out to give battle to the Mexican leader; but the latter no sooner learned of his coming, than he fled with all his men. Finding it impossible to force him to give battle, Fremont encamped near the town, where he waited until joined by Commodore Stockton and a company of marines.
The junction effected, they marched upon Los Angeles which immediately fell into their hands. Long before this, Fremont had become impressed with the necessity of having some communication with Washington. In one sense it may be said he was all at sea, for he was without positive instructions, at a critical period, when it was most important that his line of policy should be clearly defined by his government.
But the matter of communicating with headquarters, thousands of miles away, was infinitely more difficult and serious than it is today. A vast, wild, perilous and almost unknown tract stretched between the Pacific and Atlantic, across which it required weeks and sometimes months for an express rider to make his way. To send despatches around Cape Horn took a much longer time; but the necessity was so urgent that Fremont sent Carson with fifteen picked men across the plains, instructing him to complete the journey if possible in sixty days.
Carson started in the middle of September, 1846, and by the exercise of his consummate skill he passed rapidly through a most dangerous section without running into any special danger until the third day. Then, when in the neighborhood of the copper mines of New Mexico, he suddenly came upon an encampment of Apaches, one of the most hostile tribes and the most daring of fighters in the whole southwest.
This was another of those critical occasions where Carson's wonderful quickness of mind enabled him to make the right decision without a second's delay. He understood the language, customs and peculiarities of the people, and he knew them to be splendid riders and tiger-like warriors. The least evidence of timidity would invite an overwhelming attack: a bold front and what may be called indomitable "cheek" were all that was likely to take them through.
Telling his men to halt, Carson galloped forward until within a few rods of the warriors, when he reined up and called out that he wished to hold a parley with them. Thereupon, a number advanced to hear what he had to say. The mountaineer stated that he and his friends were simply travellers through the Apache country; while they were prepared for war, they desired peace, and as their animals were tired out they wished to exchange them for fresh ones. The Apaches expressed themselves satisfied with the proposal, and Carson carefully chose a camping site, where they could best protect themselves against treachery. Then the exchange was made, both parties being so well satisfied that they parted with many expressions of good will.
It was impossible to carry any extended stock of provisions, the party depending upon their rifles to supply their needs in that direction; but game proved to be very scarce and they suffered much until they reached the first Mexican settlement. Although those people were at war with the United States, their friendship for Carson led them to supply abundantly all the wants of himself and friends.
