The Royal School of Artillery Signals Section displayed a sign "No Comms - No Bombs"

In World War One Artillery communications realy meant line. Radio was in it's infancy and mainly confined to air observation. Signal rockets could be used to call for fire on SOS targets. However, it was line, miles and miles of line and the courage of the signallers of the Royal Artillery, to lay and reapair the line, often under fire, that provided communiations.

Line was required:

• From Observers to the Battery Gun positions to initiate and control fire
• From Battery Gun position to wagon lines in order to call ammunition forward
• Line between command posts and officeres messes
• Line back from Battery to Brigade Headquarters or Heavy Artillery Group (HAG) Headquarters
• Line from Brigade and HAG heaquarters to higher formation headquarters

and it was not just one line. In order to ensure communications were maintaned multiple lines would be laid between locations in case one line was cut. In prpearation for the Somme line, was buried to a depth of 6 feet to protect it from the German 5.9" enemy shells; 7,000 miles underground line and 43,000 miles of surface line was laid.
