Jackson only lost one battle in his career, at Kernstown, VA, on March 23, 1862. This loss has been attributed to bad intelligence: Jackson was told that there was only about one regiment of Union soldiers in the area, but encountered a full division of 8,500 men, confronting his 3,800. He attempted to turn the Union right flank, but was beaten back, and the North held the field. The result, however, proved more complex.

The North discovered that its intent to reinforce its armies marching on Richmond would be fought by Jackson in the Shenandoah Valley, the only feasible route the North could take to its army quickly. This valley is some 150 miles long by about 50 miles wide, and comprises the northwestern border of Virginia with West Virginia. To combat Jackson’s army of 17,000 men, President Lincoln dispatched no less than three separate armies, totaling 52,000 men, led primarily by Gens. Fremont, Banks, Schenck and Shields.

Only two other generals are even remotely in Jackson's class one is in the photo below and the other is Nathan Bedford Forrest...IMHO
