We kept warm last night, having ignited wood left in a fire pit at the center of the chamber.
Tomas, as ever, made the most helpful discoveries. He rummaged around beyond the limit of the light from the fire and fell into an alcove that contained a gasoline generator. He was able to crank it up and we had lights.
We thus learned that this place was a whole lot bigger than we thought. Other tunnels branch off the chamber to sleeping quarters, ammunition stores, and food supplies.
So we ate well and rested while awaiting the storm to subside.
The Captain regularly went outside to check the storm. The last time he was ushered back in by two soldiers.
