France Sent Message Via a Visual Telegraph Line

The visual telegraph line transmitted the first message across a 30-mile stretch of France, using the 22 stations of the Paris Lille line in 1793. It notified France’s revolutionary government, the Convention, that armies had conquered the town of Conde. The reply message, “We congratulate the brave republican soldiers and give order that Conde, bearing up to now the name of the hated nobility, should be called forever Nord-Libre,” Inventor Claude Chappe installed the first Lille line.
