It's a tie between Lee and Jackson for me although honorable mention to Brigadier General Johnathan Hunt Morgan for leading the longest raid of the civil war. He led about 2000 Confederate cavalrymen across over 1000 miles of ground through Kentucky, Indiana, and Ohio and earned the nickname "Thunderbolt of the Confederacy" he escaped Union prison twice I believe, and was killed when Union soldiers ambushed him in his sleep and killed him on sight, not wanting to take him prisoner to avoid being embarrassed by him escaping again to wreak havoc on the Union.
