Albert Sidney Johnston - U.S. Army

U.S. Army

Johnston returned to the Texas Army during the Mexican-American War under General Zachary Taylor as a colonel of the 1st Texas Rifle Volunteers. The enlistments of his volunteers ran out just before the Battle of Monterrey. Johnston managed to convince a few volunteers to stay and fight as he himself served as the inspector general of volunteers and fought at the battles of Monterrey and Buena Vista. Johnston remained on his plantation after the war until he was appointed by President Taylor to the U.S. Army as a major and was made a paymaster in December 1849. He served in that role for more than five years, making six tours, and traveling more than 4,000 miles (6,400 km) annually on the Indian frontier of Texas. He served on the Texas frontier at Fort Mason and elsewhere in the West. In 1855 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. As a key figure in the Utah War, he led U.S. troops who established a non-Mormon government in the formerly Mormon territory. He received a brevet promotion to brigadier general in 1857 for his service in Utah. He spent 1860 in Kentucky until December 21, when he sailed for California to take command of the Department of the Pacific.
