There is a mysterious element to this story, about the Australian soldiers who left graffiti on the walls of underground caves beneath the French village of Naours.
Recently, rediscovered subterranean caves of Naours have revealed details of engravings, signatures and carvings on the walls of the caves.

There are over 3000 signatures recorded on the walls throughout the network of man-made underground caves.

Naours is close to the town of Vignacourt where Australians spent much time on leave during service in WW1. 

The authors have researched the graffiti and drawings and where possible have given life to the signatures by matching them to the names of Australian soldiers with their biographies.  A unique story which is somewhat similar, as you may remember, to the 'Lost Digger' photographs found at Vignacourt several years ago.
