Bennet Riley was born to an Irish-Catholic couple, Bennet Riley and Susanna Ann Drury in St. Mary's, Maryland, 1787. His father apprenticed him to a cobbler; later, he served as a foreman in a shoe factory. After his father's death in 1811, he signed up for service on a privateer. Riley married Arabella Israel, of Philadelphia, on 9 November 1834, at the Jefferson Barracks, Lemay, Missouri. They had eight children: William Davenport Riley and Samuel Israel Riley, twins, died in Fort King, Florida, on 15 and 17 November 1841; Bennet Israel Riley, born 1835 in Massachusetts, served in the Navy and died aboard the war-sloop, which disappeared with all hands in September, 1854; Mary, born 1836; Arabella I. Riley, 1837–1916) ; George, born 1838; and Edward Bishop Dudley Riley, whose military career was split between the Union and Confederate armies. Ulysses S. Grant described Bennet Riley as "the finest specimen of physical manhood I had ever looked upon...6'2 in his stocking feet, straight as the undrawn bowstring, broad shouldered with every limb in perfect proportion, with an eagle and a step as light as a forest tiger." An accident or injury in his youth caused him to lose part of his palette, and he spoke with a hoarse voice.
Military career
Riley volunteered for service in the War of 1812, and on 19 January 1813, he was appointed Ensign of Rifles. In March of the same year, he became a third lieutenant and in April 1814 a second lieutenant in the First Rifles. He saw action at Sackets Harbor, New York, in second of two battles for control of the shipyards on Lake Ontario. He gained a promotion to first lieutenant in March 1817. Riley was further advanced to captain in the 5th U.S. Infantry, and by 1821 he was transferred to the 6th U.S. Infantry. The officer joined his superior, ColonelHenry Leavenworth, in an engagement against the Arikara Indians in August 1823. Riley was honored for ten years of faithful service by being promoted to brevetmajor on 6 August 1828, leading the first military escort along the Santa Fe Trail in 1829. He had tenures as major in the 4th U.S. Infantry and lieutenant colonel, 2nd U.S. Infantry, beginning in December 1839. The Battle of Chokachotta in Florida took place on 2 June 1840. Colonel Riley was cited for bravery and good conduct during this engagement in the Seminole Wars. He gained the rank of Brevet Colonel in February 1844. During the Mexican–American War, as colonel of the 2nd U.S. Infantry, Riley fought at the Siege of Veracruz and the Battle of Cerro Gordo, where he was cited for bravery. He was brevetted brigadier general and assumed command of the 2nd Brigade in David E. Twiggs's Second Division. He led his brigade at the Battle of Contreras and the Battle of Churubusco, where Winfield Scott gave him credit for the U.S. victory: Riley had discovered a way around the rear of Velencia's position. He was appointed brevet major general and fought at the Chapultepec. After the battle at Churubusco, he also presided over the courts-martial of 72 deserters of the so-called Saint Patrick's Battalion discovered hiding in the San Patricios convent; among them were John Murphy and John Riley. He was generally considered one of the ablest brigade commanders in the army during the war with Mexico.
Role in California statehood
After the war with Mexico, Riley served a brief stint at Fort Hamilton, in Brooklyn, New York, in 1848. In the years 1849 and 1850, General Riley commanded the Military Department in Upper California and exercised the duties of Provincial Governor: the inaction of Congress in deciding the issue of California statehood complicated his service. He relieved Colonel Richard B. Mason on 13 April 1849, as the Gold Rush worked into its most violent phase. In addition to the influx of prospectors seeking their fortunes, daily desertions of his own men rapidly depleted his troops. At the height of the Gold Rush, he had eight companies of infantry, two artillery, and two dragoons stretched between San Diego and San Francisco. When Congress refused to act on the statehood of California and New Mexico, he called for the election of civil officers to a de facto government. Consequently, the military authorities could not prevent the slaughter of California's native population, nor could they suppress the violence in the lawless gold camps. He relinquished all his civil power on 20 December 1849. After his administrative service concluded on the Pacific, Riley was ordered to take command of a regiment on the Rio Grande. However ill-health prevented further service on his part. He returned to his home in Black Rock, near Buffalo, New York, where he died of cancer. General Riley died on Thursday evening, 10 June 1853, survived by his wife Arabella and four children. Riley is buried at Forest Lawn Cemetery, Buffalo.
Legacy
On 27 June 1853, Camp Center was named Fort Riley in Bennet Riley's honor, even though he never served at the fort, and it was a cavalry post, while Riley's career was that of an infantryman. Riley County, Kansas is also named in his honor.
