Joseph E. Johnston
Joseph Eggleston Johnston (February 3, 1807 – March 21, 1891) was a career U.S. Army officer, serving with distinction in the Mexican-American War and Seminole Wars, and was also one of the most senior general officers in the Confederate States Army during the American Civil War. He was unrelated to Albert Sidney Johnston, another high-ranking Confederate general during the Civil war.
Johnston was trained as a civil engineer at the U.S. Military Academy. He served in Florida, Texas, and Kansas, and fought with distinction in the Mexican-American War and by 1860 achieved the rank of brigadier general as Quartermaster General of the U.S. Army. When his native state of Virginia declared secession from the Union, Johnston resigned his U.S. commission and became the highest-ranking U.S. officer to join the Confederacy. To his dismay, however, he was appointed only the fourth ranking full general in the Confederate army.
