The next morning, the two men discuss the situation at the fort. The Volks have not attacked since the previous battle, and the rear reserve troops are concerned about the front line situation. The two wonder if they will be able to break through to the front from now on, but they do not know what the Volks are planning. They decide to go down to check out the situation. They find that there is no vertical shaft on the map, and they wonder if the enemy is planning to bury their entire camp underground. They also find out that the light bulbs are broken, and that the soldiers have been poisoned by a tiny amount of poisonous gas. The soldiers are shocked, and one of them says that he knows a soldier who uses this poison, but he does not know how he came to be poisoned.
