On faulty intelligence, Confederate Major General T.J. Jackson had moved on Winchester, Virginia in a series of gruelling marches to engage what he thought was a smaller Union force under Brigadier General Shields. Instead, he met a larger Union concentration under Colonel Nathan Kimball at the first battle of Kernstown and was driven from the field in his only defeat ot the war. The encounter did, however, affect Union strategy and Jackson was able next to embark on his successful Shenandoah Valley campaign. (By John Osborne)
