Convention for the Protection of Submarine Telegraph Cables

The convention made it a punishable offence to damage submarine communications cables. In addition, all ships were to be regulated to staying a distance of 1 nautical mile (1.9 km) away from cable laying ships when in operation. Any ship that accidentally hooked a cable and sacrificed its fishing nets to avoid breaking it would be compensated for the lost equipment.[3]
