Alfred Pleasonton (June 7, 1824 – February 17, 1897) was a United States Army officer and major general of volunteers in the Union cavalry during the American Civil War. He commanded the Cavalry Corps of the Army of the Potomac during the Gettysburg campaign, including the largest predominantly cavalry battle of the war, Brandy Station. In 1864, he was transferred to the Trans-Mississippi theater, where he defeated Confederate General Sterling Price in two key battles, including the Battle of Mine Creek, the second largest cavalry battle of the war, effectively ending the war in Missouri. He was the son of Stephen Pleasonton and the younger brother of Augustus Pleasonton.

Early life

Pleasonton was born in Washington, D.C., on June 7, 1824. He was the son of Stephen and Mary Hopkins Pleasonton. Stephen was well-known at the time of Alfred's birth. During the War of 1812, as a U.S. State Department employee, he saved crucial documents in the National Archives from destruction by the British invaders of Washington, including the original Declaration of Independence and the U.S. Constitution. As Fifth Auditor of the U.S. Treasury, Stephen Pleasonton was the de facto superintendent of lighthouses of the United States from 1820 to 1852. His conservative approach and emphasis on the economy held back advancements in lighthouse construction and technology and led to the deterioration of some lighthouses. Since he had no technical knowledge of the field, he delegated many responsibilities to local customs inspectors. In 1852, the U.S. Congress decided reform was needed and established the Lighthouse Board to take over fiscal and administrative duties for U.S. lighthouses.

Alfred's much older brother, Augustus, attended the United States Military Academy and served as Assistant Adjutant General and paymaster of the state of Pennsylvania; his career direction obviously affected his younger brother's and both boys were assured nomination to the Academy by their father's fame from the War of 1812. Alfred graduated from West Point on July 1, 1844, and was commissioned a brevet second lieutenant in the 1st U.S. Dragoons (heavy cavalry). He was promoted to first lieutenant on September 30, 1849.

He was wounded in the right ear by the concussion of an artillery shell at the Battle of Antietam on September 17. Nevertheless, his claims earned him an appointment to the grade of major general of volunteers on and to rank from June 22, 1863, and when the inept Cavalry Corps commander, Maj. Gen. George Stoneman, was relieved after Chancellorsville, Hooker named Pleasonton as his temporary replacement. Pleasonton could not accept even this elevated role gracefully. He wrote to Gen. Hooker "I cannot ... remain silent as to the unsatisfactory condition in which I find this corps ... the responsibility of its present state ... does not belong to me."

Gettysburg

Pleasonton's first combat in his new role was a month later in the Gettysburg campaign. He led Union cavalry forces in the Battle of Brandy Station, the largest predominantly cavalry battle of the war. The Union cavalry essentially stumbled into J. E. B. Stuart's Confederate cavalry and the 14-hour battle was bloody but inconclusive, although Stuart was embarrassed that he had been surprised and the Union horsemen had a newfound confidence in their abilities. Subordinate officers criticized Pleasonton for not aggressively defeating Stuart at Brandy Station. Gen. Hooker had ordered Pleasonton to "disperse and destroy" the Confederate cavalry near Culpeper, Virginia but Pleasonton claimed that he had only been ordered to make a "reconnaissance in force toward Culpeper", thus rationalizing his actions.

In the remainder of the Gettysburg Campaign up to the climactic battle, Pleasonton did not perform as a competent cavalry commander and was generally unable to inform his commander where the enemy troops were located and what their intentions were. The Army of Northern Virginia, under Gen. Robert E. Lee, was able to slip past Union forces through the Shenandoah Valley and north into Pennsylvania. During this period, he attempted to exercise political influence by promoting the nephew of a U.S. Congressman, Captain Elon J. Farnsworth, a member of his staff, directly to brigadier general. Pleasonton also promoted Captain Wesley Merritt and First Lieutenant George Armstrong Custer to brigadier general.

Pleasonton corresponded with the congressman and complained about his lack of men and horses in comparison to Jeb Stuart's; he also politicked to acquire the cavalry forces of Maj. Gen. Julius Stahel, who commanded the cavalry in the defenses of Washington. The machinations worked. Stahel was relieved of his command and his troopers were reassigned to Pleasonton. Gen. Hooker was enraged by these activities and it was probably only his own relief from command on June 28, 1863, that saved Pleasonton's career from premature termination.

In the Battle of Gettysburg, Pleasonton's new commander, Maj. Gen. George G. Meade, understood Pleasonton's reputation (and his father's) and kept him on a short leash. For the three days of the battle, Pleasonton was forced to remain with Meade at army headquarters, rather than with the Cavalry Corps headquarters nearby, and Meade exercised more direct control of the cavalry than an army commander normally would. In postwar writings, Pleasonton attempted to portray his role in the battle as being a major one, including predicting to Meade that the town of Gettysburg would be the decisive point and, after the Confederate defeat in Pickett's Charge, that he urged Meade to attack Gen. Lee and finish him off. He conveniently made these claims after Meade's death, when dispute was impossible. On the other hand, however, Pleasonton cannot be blamed for the unfortunate cavalry action on July 3, when Meade ordered the division of Brig. Gen. Judson Kilpatrick to attack the right flank of the Confederate army, which resulted in a suicidal assault against entrenched infantry and the futile death of Brig. Gen. Elon Farnsworth. After Pleasonton was removed the field, Meade was impressed with his performance from headquarters as an acting chief of staff during the battle.

Trans-Mississippi

Pleasonton was transferred to the Trans-Mississippi Theater and commanded the District of Central Missouri and the District of St. Louis on July 4, 1864.

On April 10, 1866, President Andrew Johnson nominated Pleasonton for appointment as a brevet brigadier general in the regular army for the campaign in Missouri, to rank from March 13, 1865, and the U.S. Senate confirmed the appointment on May 4, 1866 (and July 14, 1866, after changes in the date of rank for brevet appointments for non-field service). On July 17, 1866, President Johnson nominated Pleasonton for appointment as a brevet major general in the regular army for his overall conduct in the war, to rank from March 13, 1865, and the U.S. Senate confirmed the appointment on July 23, 1866.

Postbellum career

After the war, although Pleasonton had achieved the honorary rank of brevet major general in the regular army, he was mustered out of the volunteer service with the permanent rank of major of cavalry. Because he did not want to leave the cavalry, Pleasonton turned down a lieutenant colonel in the infantry and soon became dissatisfied with his command relationship to officers he once outranked. Pleasonton resigned his commission in 1868 and was placed on the Army's retired list as a major in 1888. Pleasonton, always more of a bureaucrat than an ideologue or strong leader, only wanted to defeat the South's military capabilities so that they could not threaten the rest of the states, but was not convinced that "crushing" the rebels, ending slavery, or reelecting Lincoln was worth the cost.

Alfred Pleasonton died in his sleep in Washington, D.C., on January 17, 1897, and is buried in the Congressional Cemetery there, alongside his father. The city of Pleasanton, Kansas, also named for Pleasonton, held its first "General Pleasonton Days" celebration in 2007. On the huge Pennsylvania Memorial at the Gettysburg Battlefield stands a statue of General Pleasonton.
