The Montsou strike and Voreux catastrophe
Étienne Lantier, an unemployed machinist, takes work at the Voreux pit in Montsou, where the company cuts pay by changing how timbering is paid. He organises a provident fund and then a strike that starves the miners for weeks, turns into a mob that wrecks neighbouring pits, and ends when troops fire on the crowd and kill Maheu, one of the strikers. The miners go back down defeated, and Souvarine, an anarchist, sabotages the shaft lining so that the Voreux floods and collapses, trapping Étienne, Catherine and Chaval underground.
