The Battle of Front Royal, also known as Guard Hill or Cedarville, was fought May 23, 1862, in Warren County, Virginia, as part of Confederate Army Maj. Gen. Thomas J. "Stonewall" Jackson's Campaign through the Shenandoah Valley during the American Civil War. Front Royal demonstrated Jackson's use of Valley topography and mobility to unite his own forces while dividing those of his enemies. At a minimal cost, he forced the withdrawal of a large Union army by striking at its flank and threatening its rear.
