Ripley was born in
Worthington, Ohio, a small village in
Franklin County not far from
Columbus. His family relocated to the state of
New York, where he received an appointment to the
United States Military Academy. He graduated in 1843, ranked 7th out of 39 cadets. Other classmates in his year included
Ulysses S. Grant,
William B. Franklin,
Samuel G. French and
Franklin Gardner. He was assigned as a
second lieutenant to garrison duty, as well as becoming an
artillery instructor. Lieutenant Ripley served in the
Mexican–American War on the staffs of Gen.
Zachary Taylor and Gen.
Gideon Pillow, and saw action at the battles of
Monterey,
Vera Cruz,
Cerro Gordo,
Contreras,
Churubusco,
Molino del Rey,
Chapultepec, and the
capture of Mexico City. For gallantry in action, Ripley was
brevetted captain for Cerro Gordo and
major for Chapultepec. He published a
History of the Mexican War (2 vols., New York, 1849). He was engaged in the
Second Seminole War in
Florida in 1849, where again he saw combat. Following the war, he was on garrison duty in various posts in the South, including
Fort Moultrie on
Sullivan's Island,
South Carolina. Also living on the island was a wealthy widow, Alicia (Middleton) Sparks (1824–1899), from
Charleston. They married in 1852. The novelist
William Gilmore Simms was living on the island at the time, and tells of an incident during their courtship involving Ripley's boots and a barman. Alicia's uncle was
Arthur Middleton Manigault, later a Confederate general. Ripley resigned from the army in 1853 and moved to Charleston to settle his wife's estates. From 1853–1854 he was the publisher, along with
Charles G. Baylor, of the Baltimore
Daily American Times. He later established a successful business, and, over time, Ripley became a supporter of
states rights. He joined the South Carolina state
militia and became a
major of ordnance. ==Civil War==
