The Battle of Buena Vista of 1847, General Taylor met Santa Anna, who had brought an army of 20,000 Mexican troops. Taylor's army won the hard-fought battle, which left hundreds killed and wounded on both sides. When it was over, Santa Anna chose to declare victory rather than continue to struggle. He abandoned northeastern Texas to Taylor because of a serious threat to his capital. Pressing for a complete victory, Polk sent forces under General Winfield Scott to take Mexico City. In March 1847, Scott captured the port city of Veracruz. There, he marched of 10,000 men toward Mexico City. After fierce fighting, Scott defeated Santa Anna's forces and captured the Mexican capital on September 14th, bringing the war to an end. The Mexican-American war lasted from 1846-1847. Fort Sumter began when tension was mounting in the waters outside Charleston, South Carolina. Federal troops continued to occupy Fort Sumter, a federal fort on an island in Charleston's harbor. A federal ship sent to supply the fort in January had been forced to turn back when Confederate forces fired on it. The federal soldiers under the command of Major Robert Anderson were running out of supplies. If Lincoln didn't resupply the fort, it would have to be abandoned to the Confederates. To keep the fort, or even to send new troops there, might make him responsible for starting a war. Yet to abandon the fort would mean acknowledging the authority of the Confederate government. On April 6, Lincoln told the governor of South Carolina that he was sending food, but no soldiers or arms. On April 10, before supplies could arrive, Confederate president Davis ordered General P.G.T. Beauregard to demand that Fort Sumter surrender. Beauregard opened fire on the fort, after a 34-hour bombardment, Anderson surrendered Fort Sumter to Confederate troops.
