Pedro de Ampudia, Mexican general, was born in Cuba in 1803. As an artillery officer in the Mexican army, he participated in the capture of the Alamo and, after the Mexican defeat at San Jacinto, retreated with José de Urrea's army. Ampudia was commander of the units of the Mexican army stationed at Matamoros at the time of the Mier expedition, defeated the Texans at Mier in December 1842, and in January 1843 marched them as prisoners to Matamoros. He was appointed general in chief of the Mexican Army of the North just before the outbreak of the Mexican War and arrived at Matamoros on April 11, 1846, where he demanded that Gen. Zachary Taylor retreat to the Nueces River. After being succeeded in command by Mariano Arista, who arrived at Matamoros on April 24, 1846, Ampudia fought in the battles of Palo Alto and Resaca de la Palma, regained command of the army, and was the commanding officer at the siege and fall of Monterrey. He surrendered the city to Taylor on September 23, 1846. In February 1847 he took part in the battle of Buena Vista. In 1864 Ampudia commanded the eastern liberal army. He died on August 7, 1868, and was buried in the Panteón de San Fernando.
