'Erasmus Darwin Keyes' (
May 29 1810 –
October 14 1895) was a businessman, banker and military general, noted for leading the
IV Corps of the
Union Army of the Potomac during the first half of the
American Civil War.
Early life and career
Keyes was born in
Brimfield, Massachusetts. While still a youth, Keyes' family moved to
Kennebec County, Maine. Although his father, Justus, was renown as a physician and surgeon, Erasmus decided to pursue a military career and enrolled in
West Point. Erasmus graduated 10th out of a class of 45 in 1832, and was commissioned as as a
second lieutenant in the 3rd
Artillery.
Keyes served in Charleston Harbor, during the
nullification troubles of 1832–33, and served as an aide to General
Winfield Scott from 1837–1841. Keyes was promoted to
captain on
November 30,
1841. He served in various garrisons until 1844 and then functioned as an artillery and
cavalry instructor at West Point. During 1844, he was a member of the Academy's Board of Visitors. Keyes received his commission of
major on
October 12 1858, and after his service at West Point, he was then sent on
frontier and garrison duty until 1860. General Scott appointed Keyes his military secretary on
January 1 1860, a position Keyes filled until April 1861.
Civil War
At the initial outbreak of the Civil War, Keyes was promoted to
colonel of the 11th U.S. Infantry on
May 14 1861, and three days later was promoted to the rank of
brigadier general of the U.S. Volunteers. General Keyes then served briefly on the staff of
New York Governor Edwin D. Morgan until
June 251861, overseeing that state's raising of militia.

At the battle of
First Manassas, Keyes commanded the 1st Brigade, 1st Division (Tyler), and then led Keyes' Brigade, before assuming command of a division from
November 9 1861 –
March 13 1862. He was then given command of IV Corps, leading it from its inception on
March 3 1862, until its discontinuation on
August 1 1863. When Major General
George B. McClellan's big push against
Richmond was organized in the spring of 1862, Keyes led in unexceptionable fashion during the
Peninsula Campaign.
Keyes saw action at Lee's Mill, Yorktown, Bottom's Bridge, Savage's Station, Fair Oaks, Charles City Cross Roads, Malvern Hill, and Harrison's Landing. For gallantry at the
Battle of Fair Oaks, Keyes received the
brevet of
brigadier general in the
Regular Army. After the Army of the Potomac left the Pensinsula, the IV Corps remainded behind as a part of General
John Adams Dix's Department of Virginia. General Keyes was promoted to Major General of U.S. Volunteers on
May 5 1862. In addition to the IV Corps, he commanded the Yorktown District,
VII Corps, and the division at
Suffolk. Among Keyes' other actions were the raid to White House, Virginia on
January 7 1863, and the expedition to West Point, Virginia, on
May 7 1863.
During the
Gettysburg Campaign in 1863, Keyes fell afoul of General Dix's strategic plan to demonstrate heavily against Richmond in order to divert Confederate reenforcements from General
Robert E. Lee's army in
Pennsylvania. Keyes retreated from a position near what is now Tallysville,
Virginia in the face of what Dix deemed to be inferior forces, so Dix had Keyes removed from command.
Although Keyes asked for an investigation of the charges that led to his removal, the request was never granted. Keyes then served on various boards and commissions, including the board for retiring disabled officers from
July 15 1863, until his resignation and retirement from the army on
May 6 1864.
Postbellum activities
Following his war service, Keyes moved to
San Francisco, where he soon became financially successful and prominent. He converted to
Catholicism in San Francisco in 1866. He was president of a Mexican gold mining company in 1867 – 1869, and vice president of the California vine-culture society from 1868–1872. He also was engaged in the savings and loan business.
Keyes was the author of ''The Rear Guard at Malvern Hill'' as part of
The Century Company's ''Battles and Leaders of the Civil War'' series, as well as ''Fifty Years' Observation of Men and Events''(New York, 1884) This was later reprinted as "Fighting Indians in Washington Territory"(Fairfax WA 1988) .
While on a trip to Europe with his wife, he died in
Nice, France, at age 85.
He was ultimately laid to rest at
West Point Cemetery.
