Albert Sidney Johnston (February 2, 1803 – April 6, 1862) served as a general in three different armies: the Texian (i.e., Republic of Texas) Army, the United States Army, and the Confederate States Army. He saw extensive combat during his military career, fighting actions in the Texas War of Independence, the Mexican–American War, the Utah War, and the American Civil War.
Considered by Confederate President Jefferson Davis to be the finest general officer in the Confederacy before the emergence of Robert E. Lee, he was killed early in the Civil War at the Battle of Shiloh. Johnston was the highest-ranking officer, Union or Confederate, killed during the entire war. Davis believed the loss of Johnston "was the turning point of our fate".
Johnston was unrelated to Confederate general Joseph E. Johnston....LESS
