Guilford Signal Station
Guilford Signal Station: Tracking the Confederates
History: During the Civil War signal stations served as early warning posts, observation posts and communication centers. On June 19, 1863, nearly 15,000 Union troops of Gen. John F. Reynolds' I Corps marched along the Alexandria, Loudoun & Hampshire Railroad to Guilford Station. At the Lanesville house, Reynolds erected a signal station - at 442 feet, one of the highest points in the region. The signal officer constantly communicated with nearby signal stations attempting to locate Gen. Robert E. Lee's Army of Northern Virginia. Lee slipped through the Blue Ridge Mountain gaps to the Shenandoah Valley, but the U.S. Signal Corps detected him as he began his second invasion of the North. On June 24, Reynolds' pursued Lee. The two armies clashed in Gettysburg, Pennsylvania.
