Sam Houston and Thomas J. Rusk were elected United States senators. Rusk, who was a native of South Carolina, was one of the signers of the Texan declaration of independence. He was Secretary of War under President Burnet, and fought gallantly in the ranks at the battle of San Jacinto. After General Houston’s resignation he was made commander-in-chief of the army. Rusk had taken an active part in the war against the Cherokee Indians. Later he had been chief justice of the Republic. He had devoted himself for many years with great unselfishness to the interests of the Republic. He continued to serve the State with the same fidelity. He died by his own hand in 1857. Grief at the death of his wife was the cause of this fatal act. 2. ACROSS THE BORDER. Mexico was indignant at seeing Texas, which she still claimed as one of her provinces, about to enter the Union. As soon as the Annexation Bill was passed by the United States Congress, Don Juan Almonte, formerly aide-de-camp to General Santa Anna, now the Mexican minister at Washington, D.C., was recalled, and preparations for war were begun on a grand scale in Mexico. In the meantime, the United States government had sent General Zachary Taylor to Corpus Christi on the Texas coast, with four thousand troops. He was ordered to march westward and take up a position on the Rio Grande River, the boundary line between Texas and Mexico. He was further ordered to confine himself to Texas soil unless the Mexicans should attempt to cross the river. In the spring of 1846 General Taylor began his march across the country, “which appeared like one vast garden wavy with flowers of the most gorgeous dyes.”[33] Then came a desert-like waste in which there was neither water nor any growing thing. “The sand was like hot ashes, and when you stepped upon it, you sank up to the ankles.”[33] But the region beyond the desert was fertile and inviting. At the Sal Colorado, a stream thirty miles east of the Rio Grande, some Mexican soldiers appeared. They insisted that all the country west of the Colorado belonged to Mexico, and declared that if the Americans attempted to cross that stream they would fire upon them. General Taylor paid no attention whatever to their threats. He led his troops over the Sal Colorado without further trouble and continued his march toward the Rio Grande. There the war began in real earnest. The first battle was fought at Fort Brown (now Brownsville), opposite Matamoras. The Americans were victorious. Two other successful engagements, Palo Alto and Resaca de la Palma, took place on Texas territory. Then General Taylor, having received large reinforcements, entered Mexico and marched upon Monterey, the great interior city of northern Mexico. About this time Santa Anna, who had been in exile and disgrace, returned to Mexico, and was immediately made commander-in-chief of the Mexican army.
