Each unit was designated a fenced area, 500 yards square. There was a small shed full of standard construction and woodworking tools in one corner and raw lumber in another. The units filed into their pens and huddled in the centers of their cages. The distance between each group was vast, though everyone still spoke in short whispered commands regardless. Unit 8 was the first to take action: 20 men grabbed 20 shovels and started digging directly in the center of their plot. Within a couple of hours they had a deep foundation framed out and were working on the roof of the fort.
