Upon his arrival, he requested command of all forces in the Valley and along the Allegheny ridges south of Winchester, formerly under General Robert E. Lee.
Rosecrans had his own plans to capture what he thought was the lightly defended town of Winchester and fortify and hold it as a base of operations to threaten Confederate positions at Manassas Junction.

Jackson left Loring's Division to occupy Romney and returned to Winchester on January 24 with his old Stonewall Brigade and Ashby's Regiment.
Although his lofty goal of recapturing western Virginia was not achieved, Jackson did succeed in both thwarting a Union attack on Winchester and in clearing his new Valley District of all Federal forces.
