"Building up the southern perimeter," Fowler said. "The ravines are shallow in a couple of places. Tanks could get through. You know what an abatis is?"
Reacher looked blank. He knew what an abatis was. Any conscientious West Pointer who could read knew what an abatis was. But he wasn't about to let Fowler know exactly how much he knew about anything. So he just looked blank.
"You fell some trees," Fowler said. "Every fifth or sixth tree, you chop it down. You drop it facing away from the enemy. The trees around here, they're mostly wild pines, the branches face upward, right? So when they're felled, the branches are facing away from the enemy. Tank runs into the chopped end of the tree, tries to push it along. But the branches snag against the trees you left standing. Pretty soon, that tank is trying to push two or three trees over. Then four or five. Can't be done. Even a big tank like an Abrams can't do it. Fifteen-hundred-horsepower gas turbine on it, sixty-three tons, it's going to stall when it's trying to push all those trees over. Even if they ship the big Russian tanks in against us, it can't be done. That's an abatis, Reacher. Use the power of nature against them. They can't get through those damn trees, that's for sure. Soviets used it against Hitler, Kursk, World War Two. An old Commie trick. Now we're turning it around against them."
"What about infantry?" Reacher said. "Tanks won't come alone. They'll have infantry right there with them. They'll just skip ahead and dynamite the trees."
Fowler grinned.
"They'll try," he said. "Then they'll stop trying. We've got machine gun positions fifty yards north of the abatises. We'll cut them to pieces."
The cautious woman came back out of the kitchen carrying a tray. She put it down on the table in front of Reacher. Eggs, bacon, fried potatoes, beans, all on an enamel plate. A metal pint mug of steaming coffee. Cheap flatware.
"Enjoy," she said.
"Thank you," Reacher said.
"I don't get coffee?" Fowler said.
The cautious woman pointed to the back.
"Help yourself," she said.
Fowler tried a man-to-man look at Reacher and got up. Reacher kept on looking blank. Fowler walked back to the kitchen and ducked in the door. The woman watched him go and laid a hand on Reacher's arm.
"I need to talk to you," she whispered. "Find me after lights-out, tonight. I'll meet you outside the kitchen door, OK?"
"Talk to me now," Reacher whispered back. "I could be gone by then."
"You've got to help us," the woman whispered.
Then Fowler came back out into the hall and the woman's eyes clouded with terror. She straightened up and hurried away.
THERE WERE SIX bolts through each of the long tubes in the bed frame. Two of them secured the mesh panel which held up the mattress. Then there were two at each end, fixing the long tube to the right-angle flanges attached to the legs. She had studied the construction for a long time, and she had spotted an improvement. She could leave one flange bolted to one end. It would stand out like a rigid right-angled hook. Better than separating the flange and then jamming it into the open end. More strength.
But it still left her with six bolts. She would have to take the flange off the leg. An improvement, but not a shortcut. She worked fast. No reason to believe Jackson would fail, but his odds had just worsened. Worsened dramatically.
NEXT TO THE mess hall were the dormitories. There were four large buildings, all of them immaculate and deserted. Two of them were designated as barracks for single men and single women. The other two were subdivided by plywood partitions. Families lived there, the adults in pairs in small cubicles behind the partitions, the children in an open dormitory area. Their beds were three-quarter-size iron cots, lined up in neat rows. There were half-size foot-lockers at the ends of the cots. No drawings on the walls, no toys. The only decor was a tourist poster from Washington, D.C. It was an aerial photograph taken from the north on a sunny spring day, with the White House in the right foreground, the Mall in the middle and the Capitol end-on to the left. It was framed in plastic and the tourist message had been covered over with paper and a new title had been hand-lettered in its place. The new title read: This
