Under the paving of Arras, lie impressive chalk quarries which were dug during the Middle Ages. During the Great War, Arras was destroyed as soon as 1914. From 1916, the Allies began preparing a diversion attack before Le Chemin des Dames assault. Their brilliant idea: the New-Zealand Tunnellers were in charge of linking up the quarries to create a true underground network where 24,000 soldiers could be quartered, waiting for the offensive to start.
