Joseph Hooker

Hooker graduated from West Point in 1837. Prior to the Civil War, he fought in the Mexican War and received several brevets through lieutenant colonel. In 1862, he was commissioned brigadier general. That spring, as a division commander under General McClellan, Hooker participated in the attack on Richmond and gained the nickname "Fighting Joe Hooker." His performances the rest of 1862 showed him to be a solid combat officer in charge of a division and then corps. Burnside's failure at Fredericksburg led to Hooker being given command of the Army of the Potomac in 1863. However, his 135,000 men were defeated by Lee and Jackson at Chancellorsville. Prior to the Battle of Gettysburg, Hooker asked to be relieved of command and was replaced by General George Meade. At Chattanooga, Hooker led the capture of Lookout Mountain from the Confederates. The promotion of Hooker's subordinate Oliver O. Howard to the command of the Army of Tennessee by General Sherman led to the end of Hooker's field service. He died in Garden City, New York in 1879.
