In August 1794, Chappe's semaphore system delivered a message to Paris of the capture of Conde-sur-l'Escaut from the Austrians, in less than an hour. This success led to more semaphore telegraph lines being built, radiating in a star pattern from Paris. The semaphore network that was built in France represented the first telecommunications network in Europe.

The semaphore system became widely copied and spread to Italy, Germany, and Russia. However, the invention of the electric telegraph was to signal the demise of semaphore, replacing it beginning in 1846.
