In Stonewall Jackson's Valley Campaign, approximately how many Union armies were tied up?

• A. Two
• B. Three
• C. Four
• D. Five

Answer: (B)

The question tests how Jackson’s maneuvering in the Shenandoah tied down multiple Union forces at once. By marching rapidly, concentrating his attack, and delivering decisive blows in sequence, Jackson forced three separate Union commands to stay in the Virginia theater rather than rejoin or reinforce each other elsewhere.

In the Valley Campaign, three distinct Union armies were kept occupied: Banks’s Army of the Shenandoah in the northern Shenandoah around Winchester/Front Royal, Fremont’s Army of the Mountain Department moving up from the east into the central Valley, and a third Union force under McDowell (and related commands operating toward Washington and the Rappahannock region) that had to respond to Jackson’s movements. Because Jackson pressed these sectors continually, each of these Union formations remained tied to the Valley operations rather than concentrating their strength against Confederates elsewhere.

So, the effect was that roughly three Union armies were tied up by Jackson’s campaign.
