General Albert Sidney Johnston (February 2, 1803 – April 6, 1862) was a U.S. military officer who served as a general officer in three different armies: the Texas Army, the United States Army, and the Confederate States Army. He saw extensive combat during his 34-year military career, fighting actions in the Black Hawk War, the Texas-Indian Wars, the U.S.-Mexican War, the Utah War, and the American Civil War, where he died on the battlefield.

Considered by Confederate States President Jefferson Davis to be the finest general officer in the Confederacy before the later emergence of Robert E. Lee, he was killed early in the Civil War at the Battle of Shiloh on April 6, 1862. Johnston was the highest-ranking officer on either side killed during the war. Davis believed the loss of General Johnston "was the turning point of our fate."

Joseph E. Johnston, a distinguished Confederate general who was not related, assumed command in the Western Theater in November 1862, several months subsequent to A.S. Johnston's passing.

Early life and education Johnston was born in Washington, Kentucky, the youngest son of Dr. John and Abigail (Harris) Johnston. His father was a native of Salisbury, Connecticut. He was a grandson of Revolutionary War patriot Edward Harris. Although Albert Johnston was born in Kentucky, he lived much of his life in Texas, which he considered his home. He was first educated at Transylvania University in Lexington, Kentucky, where he met fellow student Jefferson Davis. Both were appointed to the United States Military Academy at West Point, New York, though Davis was two years behind Johnston.Woodworth, p. 46. In 1826,Chisholm, p. 472 Johnston graduated eighth of 41 cadets in his class from West Point with a commission as a brevet second lieutenant in the 2nd U.S. Infantry.Eicher, p. 322.

Johnston was assigned to New York and Missouri posts. In August 1827, he participated in the expedition to capture Red Bird, the rebellious Winnebago chief. Johnston later wrote: "I must confess that I consider Red Bird one of the noblest and most dignified men I ever saw... He said: 'I have offended. I sacrifice myself to save my country.'" Johnston served in the brief Black Hawk War of 1832 as chief of staff to Brevet Brigadier General Henry Atkinson. The commander praised Johnston for "talents of the first order, a gallant soldier by profession and education and a gentleman of high standing and integrity."

In April 1834, Johnston resigned from the United States Army to care for his wife, who had contracted tuberculosis. They moved back to Kentucky, but she died in August 1835. Johnston was then approached by an agent from the Republic of Texas, who requested his aid in the defense of the country from invasion by the Republic of Mexico. Johnston agreed, and leaving his two children in the care of relatives in Kentucky, traveled south.

Texian Army Johnston moved to Texas in 1836 and enlisted as a private in the Texian Army after the Texas War of Independence from the Republic of Mexico. He was named Adjutant General as a colonel in the Republic of Texas Army on August 5, 1836. On January 31, 1837, he became senior brigadier general in command of the Texas Army.

On February 5, 1837, Johnston fought in a duel with Texas Brigadier General Felix Huston, who was angered and offended by Johnston's promotion. Huston had been the acting commander of the army and perceived Johnston's appointment as a slight from the Texas government. Johnston was shot through the hip and severely wounded, requiring him to relinquish his post during his recovery.

Afterward, Johnston said he fought Huston "as a public duty... he had little respect for the practice of dueling." He believed that the "safety of the republic depended upon the efficiency of the army... and upon the good discipline and subordination of the troops, which could only be secured by their obedience to their legal commander. General Huston embodied the lawless spirit in the army, which had to be met and controlled at whatever personal peril."Johnston, pp. 80

Many years later, Huston said that the duel was "a shameful piece of business, and I wouldn't do it again under any circumstances... Why, when I reflect upon the circumstances, I hate myself... that one act blackened all the good ones of my life. But I couldn't challenge Congress; and President Houston, although a duelist, was too far above me in rank. Well, thank God I didn't kill him."

On December 22, 1838, Mirabeau B. Lamar, the second president of the Republic of Texas, appointed Johnston as Secretary of War. He defended the Texas border against Mexican invasion. In 1839, he campaigned against Native Americans in northern Texas during the Cherokee War of 1838–39. At the Battle of the Neches, Johnston and Vice President David G. Burnet were both cited in the commander's report "for active exertions on the field" and "having behaved in such a manner as reflects great credit upon themselves."

In February 1840, Johnston resigned his position as Secretary of War and returned to Kentucky, marrying for the second time. He purchased a large plantation in Brazoria County, Texas, named "China Grove." He leased the property out and moved his family to Galveston.

United States Army

When the United States declared war on Mexico in May 1846, Johnston rode 400 miles from his home in Galveston to Port Isabel to volunteer for service in Brigadier General Zachary Taylor's Army of Occupation. Johnston was elected as colonel of the 1st Texas Rifle Volunteers but the enlistments of his soldiers ran out just before the army's advance on Monterrey, so Taylor appointed him as the inspector general of Brigadier General William O. Butler's division of volunteers. Johnston convinced a few volunteers of his former regiment to stay on and fight.

During the Battle of Monterrey, Butler was wounded and carried to the rear, and Johnston assumed an active leadership role in the division. Future U.S. general, Joseph Hooker, was with Johnston at Monterrey and wrote: "It was through [Johnston's] agency, mainly, that our division was saved from a cruel slaughter... The coolness and magnificent presence [that he] displayed on this field... left an impression on my mind that I have never forgotten."Roland, pp. 243 General Taylor considered Johnston "the best soldier he had ever commanded."

Johnston resigned from the army just after the battle of Monterrey in October 1846. He had promised his wife, Eliza, that he would only volunteer for six months' service. In addition, President James K. Polk's administration's preference for officers associated with the Democratic Party prevented the promotion of those, such as Johnston, who were perceived as Whigs:

He remained on his plantation after the war until he was appointed by later 12th president Zachary Taylor to the U.S. Army as a major and was made a paymaster in December 1849 for a district of Texas encompassing the military posts from the upper Colorado River to the upper Trinity River. He served in that role for more than five years, making six tours and traveling more than annually on the Indian frontier of Texas. He served on the Texas frontier at Fort Mason and elsewhere in the western United States.

In 1855, 14th president Franklin Pierce appointed him colonel of the new 2nd U.S. Cavalry (the unit that preceded the modern 5th U.S.), a new regiment, which he organized, his lieutenant colonel being Robert E. Lee, and his majors William J. Hardee and George H. Thomas. Other subordinates in this unit included Earl Van Dorn, Edmund Kirby Smith, Nathan G. Evans, Innis N. Palmer, George Stoneman, R.W. Johnson, John B. Hood, and Charles W. Field, all future Civil War generals.Johnston, pp. 185 On March 31, 1856, Johnston received a promotion to temporary command of the entire Department of Texas. He campaigned aggressively against the Comanche, writing to his daughter that "the Indians harass our frontiers and the 2nd Cavalry and other troops thrash them wherever they catch them." In March 1857, Brigadier General David E. Twiggs was appointed permanent commander of the department and Johnston returned to his position as colonel of the 2nd Cavalry.

Utah War As a key figure in the Utah War, Johnston took command of the U.S. forces dispatched to crush the supposed Latter Day Saint rebellion in November 1857. Their objective was to install Alfred Cumming as governor of the Utah Territory, replacing Brigham Young, and restore U.S. legal authority in the region. As Johnston had replaced Brigadier General William S. Harney in command, he only joined the army after it had already departed for Utah. Johnston's adjutant general, and future U.S. general in the Civil War, Major Fitz John Porter wrote: "Experienced on the Plains and of established reputation for energy, courage, and resources, [Johnston's] presence restored confidence at all points, and encouraged the weak-hearted and panic-stricken multitude. The long chain of wagons, kinked, tangled, and hard to move, uncoiled and went forward smoothly."Johnston, pp. 211

Johnston worked tirelessly over the next few months to maintain the effectiveness of his army in the harsh winter environment at Fort Bridger, Wyoming. Major Porter wrote to an associate: "Col. Johnston has done everything to add to the efficiency of the command – and put it in a condition to sustain the dignity and honor of the country – More he cannot do… Don't let any one come here over Col. Johnston – It would be much against the wishes and hopes of everyone here – who would gladly see him a Brigadier General."Roland, pp. 202 Even the Mormons commended Johnston's actions, with the Salt Lake City Deseret News reporting that "It takes a cool brain and good judgment to maintain a contented army and healthy camp through a stormy winter in the Wasatch Mountains."Deseret News (1858). Edition published October 13, 1858, Salt Lake City, Utah Territory.

Johnston and his troops hoped for war. They had learned of the Mountain Meadows Massacre and wanted revenge against the Mormons. However, a peaceful resolution was reached after the army had endured the harsh winter at Fort Bridger. In late June 1858, Johnston led the army through Salt Lake City without incident to establish Camp Floyd some 50 miles distant. In a report to the War Department, Johnston reported that "horrible crimes… have been perpetrated in this territory, crimes of a magnitude and of an apparently studied refinement in atrocity, hardly to be conceived of, and which have gone unwhipped of justice."Johnston, pp. 239 Nevertheless, Johnston's army peacefully occupied the Utah Territory. U.S. Army Commander-in-Chief, Major General Winfield Scott, was delighted with Johnston's performance during the campaign and recommended his promotion to brevet brigadier general: "Colonel Johns[t]on is more than a good officer – he is a God send to the country thro' the army." The Senate confirmed Johnston's promotion on March 24, 1858.

Although disappointed to have never been given the opportunity to put the Mormons to the sword, Johnston’s time in the Utah Territory was profitable. His soldiers provided protection to emigrant wagon trains heading to California and Oregon and his officers discovered more efficient routes traversing the region. In the summer of 1859, Johnston provided carers, wagons, and an armed escort for eighteen children discovered to have survived the Mountain Meadows Massacre for their journey back to the east.
