First Messages Between Paris and Lille
- When
- 1794
- Where
- Paris-Lille line
In 1794, the first messages were successfully sent between Paris and Lille using the semaphore line.
This successful transmission demonstrated the practical application of the semaphore system. The line informed Parisians of the capture of Condé-sur-l'Escaut from the Austrians less than an hour after it occurred, highlighting the speed of the new telegraphy.
