General Taylor established a camp at Corpus Christi in the latter part of 1845, at the mouth of the Nueces. With nearly 5,000 troops, he marched, in January, to the Rio Grande to meet the Mexicans who were preparing to invade the disputed territory. Taylor established a depot of provisions at Point Isabel on the Gulf, and, upon reaching the Rio Grande, hastily built Fort Brown, opposite the Mexican town of Matamoras.
Some time later the Mexican forces reached Matamoras, and General Arista on the 26th of April notified Taylor that hostilities had begun. To emphasize his declaration, Captain Thornton with a company of dragoons was attacked the same day, and, after the loss of sixteen men in killed and wounded, was compelled to surrender to a much superior force. This was the first engagement of the war and was fought on ground claimed by both countries.
BATTLE OF PALO ALTO.
The Mexicans acted vigorously and soon placed Taylor's lines of communication in such danger that he hurried to Point Isabel to prevent its falling into the hands of the enemy. He left Major Brown with 300 men in charge of Fort Brown. The Mexicans were exultant, believing Taylor had been frightened out of the country. But that valiant officer paused at Point Isabel only long enough to make its position secure, when he marched rapidly toward Fort Brown. Reaching Palo Alto, on the road, he found the way disputed by fully 6,000 Mexicans, who were three times as numerous as his own army. Attacking the enemy with great spirit, he routed them with the loss of a hundred men, his own loss being four killed and forty wounded.
Resuming his march toward Fort Brown, Taylor had reached a point within three miles of it, when he was brought face to face with a much larger force at Resaca de la Palma. The battle was a severe one, and for a long time was in doubt; but the tide was turned by a dashing charge of Captain May with his dragoons. Despite a destructive fire of grapeshot, the horsemen galloped over the Mexican batteries, cut down the gunners, and captured the commanding officer. Taylor then pushed on to Fort Brown and found it safe, though it had been under an almost continuous bombardment, in which Major Brown, the commandant, was killed.
ROBERT E. LEE IN ONE OF THE BATTLES OF THE MEXICAN WAR.
"Always to be found where the fighting was the fiercest."
WAR DECLARED BY CONGRESS.
News of these battles was carried north by carrier pigeons and telegraph, and the war spirit of the country was roused. Congress on the 11th of May declared that war existed by the act of the Mexican government, and $10,000,000 was placed at the disposal of the President, who was authorized to accept 50,000 volunteers. The call for them was answered by 300,000, who were eager to serve in the war.
