At the expiration of two hours, the Mexican batteries began to slacken, and, at length, ceased altogether. They were unable longer to withstand the terrible and destructive fire of Ringgold's, Churchill's, Duncan's, and Ridgeley's guns, and began to fall back, for the purpose of forming a new line of battle under cover of the smoke. The Americans also formed a new line. At the expiration of an hour, the action was renewed by our artillery, which was even more destructive than before. As night was now drawing on, the Mexicans, bent on one last and most vigorous effort, poured in upon Ringgold's battery a literal tempest of balls. Captain Page fell, mortally wounded, a cannon-ball having carried away the whole of his lower-jaw; and the brave Ringgold, nearly at the same time, had both legs shot away by a cannon-ball, which passed through his horse. On the 11th, he died at Point Isabel.

With great spirit and determination did Arista and his army maintain the contest; but it was in vain. They were at length driven from the field in hopeless disorder. Night put an end to the contest; and the wearied and exhausted victors sank upon the field, where they chanced to be, glad to find opportunity to rest from toil so severe. The force of General Taylor did not exceed two thousand three hundred; that of Arista consisted of six thousand infantry, with seven pieces of artillery, and eight hundred cavalry. The loss of the Americans was but four men killed—three officers—and thirty-seven wounded. Two hundred Mexicans were killed; four hundred wounded. Some estimate their loss in killed, wounded, and missing, little short of one thousand.

Charge of Captain May.

Resaca de la Palma.—At two o'clock, on the following day, the American army moved from the field of victory, at Palo Alto, towards Fort Brown. Towards evening, what was their surprise when, on approaching a ravine, called Resaca de la Palma, or the Dry River of Palma, they discovered the Mexican army occupying this exceedingly well-selected spot, and drawn up in battle array. A vigorous action immediately ensued. The Mexican artillery became engaged with Ridgeley's battery, as the latter moved up the ravine. Generals La Vega and Requena superintended the former, and the effect of the firing soon began to be severely felt along the American lines. To dislodge them, became indispensable to the safety of the Americans. The execution of this duty was assigned to Captain May, whose celebrated charge now took place. "I will do it," said May; and, turning to his troops, he rose in his stirrups, pointed to the guns before them, now pouring forth their terrific explosions, and exclaimed, "Remember your regiment! men, follow!" He struck his charger, and bounded on before them, while a deafening cheer answered his call; and immediately the whole were dashing towards the cannons' mouths. May outstripped them—fortunately, wonderfully did he escape, and wonderful was it that so many of his squadron escaped, exposed, as they were, to a fire which swept fearfully along the very line they were pursuing. Some, indeed, there met an untimely fate—seven men, among whom were the brave and noble-hearted Inge and Sacket. Terrific as was the scene, May and his followers pressed on. As they approached the battery, at a single bound, May's horse cleared it. The horses of a few others were equal to the leap, and their impetus carried them beyond the guns. Wheeling again, they drove the gunners off, and Captain Graham, and Lieutenants Pleasantson and Winship, with others, coming up, were masters of the battery. General La Vega was made prisoner. The American infantry now charged the Mexican line; for a time, the latter fought desperately, and sustained themselves with stubborn bravery; but, at length, yielding to necessity, they precipitately fled from the field. In this battle, only the outlines of which we give, the Americans captured eight pieces of artillery, several standards, large military stores, and several hundred prisoners. The loss of the Americans, in both these actions, was three officers and forty men killed. Besides the officers already named, was Lieutenant Cochrane. Thirteen officers and one hundred men were wounded. The Mexican loss was one hundred and fifty-four officers and men killed; two hundred and five wounded; missing, one hundred and fifty-six. General Taylor, following the battle, continued his march to Fort Brown; and, on the 18th, took possession of Matamoras, the Mexican settlement opposite.

Fall of Monterey.—Following the occupation of Matamoras, preparations were made, by order of the government, for an advance into the interior of Mexico. During these preparations, which occupied the space of three months, several Mexican villages, Reinosa, Wier, Revilla, and Camargo, were taken possession of. This last place, situated about one hundred and eighty miles above the mouth of the Rio Grande, was selected as a dépôt of supplies; and to this point, the several divisions of General Taylor's army were at length concentrated. The first of these divisions, two thousand and eighty, was commanded by General Twiggs; the second, one thousand seven hundred and eighty, by General Worth; the third, two thousand eight hundred and ten, by General Butler.

On the 19th of September, these several divisions reached a place called Walnut Springs, distant from Monterey three miles. The capture of this city was now the immediate object in view. It was a strongly-fortified place, with a competent garrison under command of General Ampudia. On the evening of the 19th, a reconnoisance of the fortifications was made; and, on the following day, the attack was commenced by the division of General Worth. On the 21st, the attack was renewed, and two fortified heights were taken; the guns of one of which was turned upon the bishop's palace, which had been rendered exceedingly strong. On the 22d, other heights, above the bishop's palace, were carried, and, soon after, the palace itself. As these fortifications, in a measure, commanded the city, the enemy, on the night of the 22d, evacuated all his defences in the lower part. On the morning of the 23d, the streets of the upper part of the city became the scene of action. Here the battle raged. All that day the firing was kept up; the American troops proceeded from house to house—from square to square—the Mexicans resisting them at every step. The carnage was frightful.

Early on the 24th, Ampudia prepared to evacuate the town; a suspension of hostilities was, therefore, arranged till twelve o'clock; during which, at the request of Ampudia, General Taylor had an interview with him, which resulted in a capitulation; placing the town and materials of war, with certain exceptions, in the possession of the American general.
