Victor Hugo, in his _Quatrevingt Treise_, speaking of the war in La Vendée, says: "It is difficult to picture to oneself what these Breton forests really were. They were towns. Nothing could be more secret, more silent, and more savage. There were wells round and small, masked by coverings of stones or by branches. The interiors at first vertical, then carried horizontally, spread out underground like tunnels, and ended in dark chambers." These excavations, he states, had been there from time immemorial. He continues: "One of the wildest glades of the wood at Misdon, perforated by galleries and cells, out of which came and went a mysterious society, was called 'The Great City.' The gloomy Breton forests were servants and accomplices of rebellion. The subsoil of every forest was a sort of sponge, pierced and traversed in all directions by a secret highway of mines, cells and galleries. Each of these blind cells could shelter five or six men. Usually the cover, made of moss and branches, was so artistically fashioned that, although impossible on the outside to distinguish it from the surrounding turf, it was very easy to open and close from the inside. In several of these forests and woods there were not only subterranean villages grouped about the burrow of the chief, but also actual hamlets of low huts hidden under the trees. These underground belligerents were kept perfectly informed of what was going on. Nothing could be more rapid, nothing more mysterious, than their means of communication. Sometimes they raised the cover of their hiding-places and listened to hear if there was fighting in the distance." He mentions the ability of the ambushed men to spring up, as it were, under the feet of the armies sent against them. And to show the numbers of the concealed forces, he continues: "There are in existence lists which enable one to understand the powerful organisation of that vast peasant rebellion. In Isle-et- Villaine, in the forest of Pertre, not a human trace was to be found, yet there were collected 6000 men under Focard. In the forest of Meullac, in Morhiban, not a soul was to be seen, yet it held 8000 men. These deceptive copses were filled with fighters, lurking in an underground labyrinth."
