SOUTERRAINS
fellows fled to the woods, caves, and secret refuges, and concealed themselves; and the gendarmes were employed in hunting them out, but not often with success unless aided by a traitor. Again in 1812, when Napoleon meditated an invasion of Russia, fresh calls were made on the male population. Every male capable of bearing arms was forced to assume them, and again, as in 1807, the young men disappeared as rabbits underground. It is quite possible that the peasants, who have found these refuges so convenient in the past, should know more about them and where they are situated than they pretend, thinking that at some future time, another revolution or another German invasion, the knowledge may prove serviceable.
And now let us turn to Picardy, perhaps the one of the ancient provinces of France most undermined. On the night of February 13, 1834, after heavy rains, a portion of the wall of the apse of the parish church of Gapennes, half-way between Aussy-le-Château and S. Ricquier, collapsed, and in the morning the inhabitants of the commune were stupefied to see the desolation of the holy place. Not only was a large breach gaping in the sanctuary, but all the walls of the chancel were fissured, and the pavement of the nave was upheaved in places and in others rent. At first it was supposed that this was the result of an earthquake, but after a while the true cause was discovered. The church had been erected over a vast network of subterranean passages and chambers, and the roofs of some of these had given way. This led to an exploration, and the plan of this subterranean refuge—for such it had been—was traced as far as possible.
But Gapennes is not the only place where such retreats exist throughout the province. Something like a hundred have been found, and more are every now and then coming to light. Indeed, it may safely be said that there is scarcely a village between Arras and Amiens and between Roye
