Fremont acquired the name of the "Pathfinder" because of his exploring expeditions in the far West. He explored a portion of the Rocky Mountains in 1842, and, in the following two years, conducted an expedition with much skill and success through the regions of Utah, the basin of the Columbia, and the passes of the Sierra Nevada. He was in charge of a third expedition in 1846, and was in California when the Mexican war broke out. He received the dispatches as if they were news to him, but there is good reason to believe that the government had sent him thither, in order that he might be on the ground and do the very work he did. He urged the pioneers to declare their independence. They ardently did so, raised the "Black Bear Flag," and gathered around Fremont, who continually defeated the superior forces of Mexicans.
The town of Monterey, eighty miles south of San Francisco, was captured by Commodore Sloat with an American squadron, and San Diego was taken soon afterward by Commodore Stockton, in command of the Pacific squadron; learning which, Fremont raised the American flag in the place of that of California, and, joining the naval commanders, advanced upon Los Angeles, which submitted without resistance. In a short time the immense province of California was conquered by what may be called a handful of Americans.
THE WONDERFUL MARCH OF COLONEL DONIPHAN.
Colonel Alexander W. Doniphan had been left at Santa Fé with his small force of dragoons. At the head of 700 men, he performed one of the most remarkable exploits of the war. Riding directly through the enemy's country for nearly a thousand miles, he reached the Rio Grande on Christmas day and won a battle; he then crossed the river and captured El Paso, and, heading for Chihuahua, was met by a Mexican force on the banks of Sacramento Creek. They outnumbered Doniphan's force four to one, and displayed the black flag, as notice that no quarter would be given. The Americans lay flat on the ground, and the first volleys passed harmlessly over their heads. The Mexicans made the mistake of believing they had been decimated by the discharge, and charged upon what they supposed were the few survivors. They were received with a withering volley, and assailed with such fierceness by the Americans that they were utterly routed. Chihuahua thus fell into the possession of Colonel Doniphan, but, since the term of the enlistment of his men had expired, he could advance no further. He then conducted them to New Orleans, where they were mustered out of service. They had marched a distance of 5,000 miles, won several victories, suffered not a single defeat, and were back again in their homes all within a year.
General Scott had landed on the coast for the purpose of marching into the interior to the national capital. In order to make his advance resistless, he withdrew the larger part of Taylor's army and united it with his own. Taylor felt he was used unjustly, for both he and Wool were threatened by Santa Anna at the head of 20,000, men, but bluff "Old Rough and Ready" made no protest and grimly prepared for the danger. The greatest number of troops he could concentrate at Saltillo was about 6,000, and, after placing garrisons there and at Monterey, he had only 4,800 remaining, but, undismayed, he marched out to meet Santa Anna. Four miles away, he reached the favorable battle ground of Buena Vista, posted his men, and awaited attack.
The Mexican commander was so confident of overwhelming the Americans that, in his message to Taylor, he assured him he would see that he was personally well treated after his surrender. General Taylor sent word that he declined to obey the summons, and the messenger who carried the message to Santa Anna added the significant words: "General Taylor never surrenders."
BATTLE OF RESACA DE LA PALMA.
Captain May leaped his steed over the parapets, followed by those of his men whose horses could do a like feat, and was among the gunners the next moment, sabering them right and left. General La Vega and a hundred of his men were made prisoners and borne back to the American lines.
The American army was placed at the upper end of a long and narrow pass in the mountains. It was flanked on one side by high cliffs and on the other by impassable ravines, which position compelled the enemy to attack him in front.
