Long before the advent of the telegraph and radio, the ancients developed methods for rapid communication over distance, using fires, flags, and banners. Signal positions were placed within visual contact of each other in a chain and simple messages could be rapidly transmitted across large distances. A defensive wall could be manned lightly while mobile reserves were kept concentrated at regular intervals. Signals could bring warnings quickly, allowing the central reserve to move to a threatened position.
