General Philip H. Sheridan
The Union's Answer to Jeb Stuart
(this is mostly from Wiki)
Sheridan claimed he was born in Albany, New York, the third child of six by John and Mary Meenagh Sheridan, immigrants from the parish of Killinkere, County Cavan, Ireland. Sheridan was born on March 6, 1831, in Albany, New York. His parents had immigrated to the United States in the year before Sheridan's birth. In 1832, the Sheridans settled in Somerset, Ohio. Philip Sheridan's father, like many other Irish immigrants, found employment on the canals and railroads. He grew up in Somerset, Ohio. Fully grown, he reached only 5 feet 5 inches tall, a stature that led to the nickname, "Little Phil." Abraham Lincoln described his appearance in a famous anecdote: "A brown, chunky little chap, with a long body, short legs, not enough neck to hang him, and such long arms that if his ankles itch he can scratch them without stooping."
Sheridan worked as a boy in town general stores, and eventually as head clerk and bookkeeper for a dry goods store. In 1848, he obtained an appointment to the United States Military Academy from one of his customers, Congressman Thomas Ritchey; Ritchey's first candidate for the appointment was disqualified by failing an examination of mathematics skill and a "poor attitude." In his third year at West Point, Sheridan was suspended for a year for fighting with a classmate, William R. Terrill. The previous day, Sheridan had threatened to run him through with a bayonet in reaction to a perceived insult on the parade ground. He graduated in 1853, 34th in his class of 52 cadets.
Brevet Second Lieutenant Philip SheridanSheridan was commissioned as a brevet second lieutenant and was assigned to the 1st U.S. Infantry regiment at Fort Duncan, Texas, then to the 4th U.S. Infantry at Fort Reading, California. Most of his service with the 4th U.S. was in the Pacific Northwest, starting with a topographical survey mission to the Willamette Valley in 1855, during which he became involved with the Yakima War and Rogue River Wars, gaining experience in leading small combat teams, being wounded (a bullet grazed his nose on March 28, 1857, at Middle Cascade, Oregon Territory), and some of the diplomatic skills needed for negotiating with Indian tribes. He lived with a mistress during part of his tour of duty, an Indian woman named Sidnayoh (called Frances by her white friends), daughter of the chief of the Klickitat Tribe. Sheridan neglected to mention this relationship in his memoirs. He was promoted to first lieutenant in March 1861, just before the Civil War, and to captain in May, immediately after Fort Sumter.
*Note: A "brevet" was a temporary promotion. If a soldier performed the duties of his "brevet" rank, he was paid in that grade. If not, he was paid at his permanent rank.
In the fall of 1861, Sheridan was ordered to travel to Jefferson Barracks, Missouri, for assignment to the 13th U.S. Infantry. He departed from his command of Fort Yamhill, Oregon, by way of San Francisco, across the Isthmus of Panama, and through New York City to home in Somerset for a brief leave. On the way to his new post, he made a courtesy call to Maj. Gen. Henry W. Halleck in St. Louis, who commandeered his services to audit the financial records of his immediate predecessor, Maj. Gen. John C. Frémont, whose administration of the Department of the Missouri was tainted by charges of wasteful expenditures and fraud that left the status of $12 million in doubt. Sheridan sorted out the mess, impressing Halleck in the process. Much to Sheridan's dismay, Halleck's vision for Sheridan consisted of a continuing role as a staff officer. Nevertheless, Sheridan performed the task assigned to him and entrenched himself as an excellent staff officer in Halleck's view.
In December, Sheridan was appointed chief commissary officer of the Army of Southwest Missouri, but convinced the department commander, Halleck, to give him the position of quartermaster general as well. In January 1862, he reported for duty to Maj. Gen. Samuel Curtis and served under him at the Battle of Pea Ridge. Sheridan soon discovered that officers were engaged in profiteering. They stole horses from civilians and demanded payment from Sheridan. He refused to pay for the stolen property and confiscated the horses for the use of Curtis's army. When Curtis ordered him to pay the officers, Sheridan brusquely retorted, "No authority can compel me to jayhawk or steal." Curtis had Sheridan arrested for insubordination but Halleck's influence appears to have ended any formal proceedings.
Sheridan performed aptly in his role under Curtis and, now returned to Halleck's headquarters, he accompanied the army on the Siege of Corinth and served as an assistant to the department's topographical engineer, but also made the acquaintance of Brig. Gen. William T. Sherman, who offered him the colonelcy of an Ohio infantry regiment. This appointment fell through, but Sheridan was subsequently aided by friends (including future Secretary of War Russell A. Alger), who petitioned Michigan Governor Austin Blair on his behalf. Sheridan was appointed colonel of the 2nd Michigan Cavalry on May 27, 1862, despite having no experience in the mounted arm.
A month later, Sheridan commanded his first forces in combat, leading a small brigade that included his regiment. At the Battle of Booneville, Mississippi, July 1, 1862, he held back several regiments of Brig. Gen. James R. Chalmers's Confederate cavalry, deflected a large flanking attack with a noisy diversion, and reported critical intelligence about enemy dispositions. His actions so impressed the division commanders, including Brig. Gen. William S. Rosecrans, that they recommended Sheridan's promotion to brigadier general. They wrote to Halleck, "Brigadiers scarce; good ones scarce. ... The undersigned respectfully beg that you will obtain the promotion of Sheridan. He is worth his weight in gold." The promotion was approved in September, but dated effective July 1 as a reward for his actions at Booneville. It was just after Booneville that one of his fellow officers gave him the horse that he named Rienzi (after the skirmish of Rienzi, Mississippi), which he would ride throughout the war.
