appeared they were now doing. Jackson turned his men around and, in one of the more grueling forced marches of the war, moved northeast 25 miles on March 22 and another 15 to Kernstown on the morning of March 23. His cavalry, under Col. Turner Ashby, skirmished with the Federals on March 22, during which engagement Shields was wounded with a broken arm from an artillery shell fragment. Despite his injury, Shields sent part of his division south of Winchester and one brigade marching to the north, seemingly abandoning the area, but in fact halting nearby to remain in reserve. He then turned over tactical command of his division to Col. Nathan Kimball, who ordered the Second Brigade and some of his own troops along the Valley Turnpike and, despite Shields's orders to pursue the Confederate cavalry, posted 16 guns and 800 infantrymen in a defensive position on the military crest of Prichard's Hill. Confederate loyalists in Winchester mistakenly informed Turner Ashby that Shields had left only four regiments and a few guns (about 3,000 men) and that these remaining troops had orders to march for Harpers Ferry in the morning. Ashby, who normally had a reputation as a reliable cavalry scout, inexplicably did not verify the civilian reports and passed them on to Jackson. Jackson marched aggressively north with his 3,000-man division, reduced from its peak as stragglers fell out of the column, unaware that he was soon to be attacking almost 9,000 men.
