Last Signal Sent
- When
- 1854
- Where
- France
The final signal from a Chappe telegraph was transmitted in 1854. No passage supports a specific 1852 supersession date or place; the legacy 1 January 1852 Paris date is unverified.
Although the decision to replace the optical telegraph occurred in 1846, the system remained in use for several years. The last signal was sent in 1854, indicating that the supersession was a gradual process rather than an immediate switch. No supplied passage connects the 1854 signal to a specific 1852 supersession event, and the legacy 1 January 1852 Paris date is unverified. 'France' is a regional context rather than a named site from allowed_places.
