He kept on his course until he approached within fifteen miles of the Mexican camp, where he halted, and despatched a party to reconnoitre. They reported on their return, that the enemy were strongly fortified in an Indian village; but in making the observation the scout had been discovered and pursued back to camp.

General Kearney determined to make an immediate attack, and commenced his march at one o'clock in the morning, with no rest that night for his animals or for his men; and weary and hungry before day, when within a mile of Castro's camp, the advance guard of the Americans came upon the advance guard of the Mexicans, which had been stationed to prevent a surprise.

This Mexican guard slept in their dress, ready at a five minutes' warning to mount in their saddles, which were their pillows, while their horses were tied to feed close around them. The sound of the trumpet commanded first a rapid trot, then a gallop, and the fifteen Americans under Captain Johnson with Kit Carson, of course, for his next officer, had a brisk fight with this Mexican outpost, but failed to stampede their animals, as each Mexican mounted his own horse immediately, and the guard drew back into camp. Capt. Johnson and Carson were now joined by Capt. Moore with twenty five Americans, a force that had united with Kearney's since he came into California, when Moore ordered an attack upon the centre of the Mexican force, in order to divide it, and cause confusion in the Mexican ranks.

The command of forty men were within a hundred yards of the enemy, and Carson among the foremost, when his horse suddenly fell and threw its rider, who was not seriously injured; but the stock of his gun was shivered to splinters, and his position one of exceeding danger, as the whole body of dragoons went galloping over him. When he could arise from the ground, he saw a dead horseman lying near, whom he relieved of gun and cartridge box, and again mounting his horse, upon whose bridle he had managed to retain his hold, he was speedily in the thickest of the fight, where the contest was becoming desperate.

Capt. Johnson and several of the soldiers in the advance had already been killed, and probably only the fall of his horse had saved Carson's life, but he was now able to assist Moore and his men to dislodge the Mexicans, and oblige them to retreat. The Americans pursued them, but as there were only forty in the whole of General Kearney's command who were mounted on horses, and the mules which were ridden by the rest had become at once unmanageable when the firing commenced, their success was not complete. The horses they had were wild, having been captured by Capt. Davidson and Kit Carson since their arrival in California, from a party of Mexicans bound for Sonora, so that even Moore's party had become scattered in the chase, and the pursuit accomplished very little.

The Mexicans immediately discovered the condition of the Americans, and turning back, recommenced the fight, which had been nearly a bloodless victory until now, but soon became for the Americans, a terrible slaughter. Every moment some dragoon yielded his life to the bullet or the deadly blow of an exasperated Mexican, and of the forty dragoons on horses thirty were either killed or severely wounded. Captain Moore, whom Carson calls, "as brave a man as ever drew the breath of life," was already among the killed. As fast as the American soldiers could come up, they joined the battle, but the Mexicans fought with a bravery unsurpassed, and seemed to carry all before them.

Gen. Kearney now drew his sword, and placed himself at the head of his remaining forces, and though severely wounded, attempted to again force the Mexicans to retreat, while Lieutenant Davidson came up with two mountain howitzers; but before he could unlimber them for use, the men who were working them were shot down, and the lasso, thrown with unerring aim, had captured the horses attached to one of them, and the gun was taken to the ranks of the enemy, who, for some reason, could not make it go off, or the American howitzer, at the distance of three hundred yards, would have done execution against those who had brought it thousands of miles to this point, to have it turned against them; though Lieutenant Davidson had nearly lost his life in the attempt to save it, but to no purpose.

The Americans were now obliged to take refuge at a point of rocks that offered, near where they had been defeated, for they had but two officers besides Carson, who were not either killed or wounded; and here they waited for the Mexicans, but they did not again venture an attack.

The fighting had continued throughout the entire day; both sides were weary and spent, and night closed over this scene of battle, without any positive result to either party. Gen. Kearney must now attend to the wounded, and all night the camp was occupied in the sad work of burying its dead, and alleviating the agony of the sufferers; while, at the same time, a close watch was kept for the enemy, who were constantly receiving reinforcements, of Indians as well as Mexicans, from the country around. A council of war was held, which at once decided it was best to advance toward San Diego in the morning, with the hope of soon receiving additions to their forces. Gen. Kearney had dispatched three men to San Diego, with messages to Commodore Stockton, and before the battle commenced, they had come back within sight of their comrades, when they were taken prisoners by the enemy; and whether they had succeeded in getting through to San Diego, Gen. Kearney did not know. Early in the morning, the command was again upon its way, with the following order of march: Carson, with twenty-five still able-bodied men, formed the advance, and the remainder, a much crippled band of soldiers, followed in the trail that he had made. Their march was continued all the morning, in the constant expectation of an attack from the Mexicans, who were also moving on, sometimes out of sight in the valleys, and sometimes seen from the neighboring hills. When the first opportunity occurred, Gen. Kearney demanded a parley, and arranged to exchange a lieutenant, whose horse had been shot from under him during the battle, and who had consequently fallen into the hands of the Americans, for one of the express messengers the Mexicans were detaining; but it availed nothing, for the expressman stated that, finding it impossible to reach San Diego, he and his companions had returned, when they were captured by the Mexicans.

The Mexicans had been manœuvering all day, and toward evening, as the Americans were about going into camp by a stream of water, came down upon them in two divisions, making a vigorous charge. The Americans were obliged to retire before such vastly superior numbers, and marched in order to a hill a little distance off, where they halted to give the Mexicans battle; but the latter, seeing the advantage of the position, drew off to a neighboring height, where they commenced and continued a deadly cannonade upon the Americans. A party of Americans was sent to dislodge them, which they accomplished, and the whole force of the Americans went over to occupy that position, as they were compelled to make a resting place somewhere, because it was no longer possible for them to continue their march, with the Mexican force ready at any time to fall upon them. Upon this hill there was barely water enough for the men, and to take the horses to the stream could not be thought of, for the Mexicans would surely capture them; nor had they any food left, except as they killed and ate their mules.
