Edward Ord
On July 10, the Union Army had taken up position around Jackson. The heaviest fighting came on July 12, during an unsuccessful Union attack. Brig. Gen. Jacob Gartner Lauman ordered a brigade under Col. Isaac C. Pugh to attack the Confederate works manned by Brig. Gen. Daniel Weisiger Adams's brigade. As a result, Lauman was relieved of command for failing to properly carry out the orders of his superior, Maj. Gen. Edward Ord, which resulted in heavy casualties. Instead of risking entrapment, Johnston chose to evacuate the state capital and withdrew on July 16. Sherman's forces occupied the city on the following day.
