 Jackson started the campaign under Lee's orders with a sweeping flanking maneuver that placed his corps into the rear of Union Maj. Gen. John Pope's Army of Virginia.The Hotchkiss journal shows that Jackson, most likely, originally conceived the movement.In the journal entries for March 4 and 6, 1863, General Stuart tells Hotchkiss that "Jackson was entitled to all the credit" for the movement and that Lee thought the proposed movement "very hazardous" and "reluctantly consented" to the movement.
