Signal Corps U.S.A.
Cumberland Township, PA
This memorial tablet honors the U.S. Signal Corps for its service at Little Round Top on July 2–4, 1863, and across the battlefields of the Civil War. From the heights, signal officers used flags to relay observations of enemy movements, giving Union commanders a crucial view of the field. The Signal Corps was then a young branch, and Gettysburg showcased the value of rapid battlefield communication.
