Thomas Jonathan "Stonewall" Jackson was born January 21, 1824, in Clarksburg, WV. He is believed to be one of the greatest Confederate leaders of all time. He got his nickname at the First Battle of Bull Run (July 1861) when one of his comrade generals said, "Look, men, there is Jackson standing like a stone wall!" Jackson suffered through a difficult childhood. His father and sister both died of typhoid, and his mother, after remarrying, died of childbirth. He then was educated at West Point, graduating just in time to fight in the Mexican-American War. After this war, Jackson decided that he wanted to lead a civilian life and became a professor. After settling down a starting a family, Jackson was called to fight in first, John Brown's Raid, and second, the Civil War. He served as a Confederate general and fought in many battles such as the First Battle of Bull Run, The Battle of Fredericksburg, and The Battle of Antietam. Sadly, after his victory at the Battle of Chancellorsville, his own side accidentally fired against him, wounding his left arm. About a week later, Jackson died from pneumonia, a result of the amputation of his injured arm.
