the machine gunners.”
                  “Sir, the fence hasn't been electrified.”
                  “Why the hell not?”
                  “The grid went down and our generators don't have enough juice for the fence.”
                  “That's great. Your men that are inside the fencing will have to be careful. Don't fire into the fence. If we cause breaches in the fence, the zombies will get in here and we'll all be dead. Try to put the barrel of your rifle through the fence before firing. Pick your targets and aim for the head. The only way to stop them is to destroy the brain.”
                  I glared at the remaining guard. “Where's that corporal. We don't have time for this.” He did his best to avoid eye contact.
                  “Sergeant, divide your men evenly into ten groups. Load ten trucks with ammunition and set up by each of the towers. The trenches should divert the zombies into firing lanes. Concentrate your men into those areas. The ground between the trenches is mined. That should slow them down and thin them out a little. Have your men support each other. They'll need to be mobile and be able to move to areas that have the most activity.”
                  The corporal I'd sent to contact the Colonel finally returned. “Sir, I can't get hold of anyone.”
                  “Where is the Colonel?”
                  “He looked to the barracks and said. “Over there.”
                  “You get this goddamn gate open now.”
                  “Yes sir.”
                  The corporal opened the first gate and was headed for the second when I saw headlights headed from the barracks in our direction. A jeep pulled up to the gate and was let through. The General and the Colonel were together in the jeep. They stopped and Colonel Bradley got out. General Simmons sped off. He was headed to the airfield. The Colonel walked over to me. I could see he'd been wounded. There was blood on his left shoulder. His shirt was soaked through. Blood was running down his arm and dripping from his fingers
                  “Captain, walk with me.” He said. “We let someone infected with the virus into the compound. They must have turned during the night. We heard screams coming from the building with the Fredericksburg refugees in it. Someone opened the door and the zombies came pouring out. I only had about twenty soldiers in there guarding the barracks. They didn't stand a chance.”
                  “As soon as the shooting started, the General forced me into a jeep with him. The son of a bitch ran like a scared rabbit. He's on his way to an air craft carrier right now.”
                  “Sir, we need to get up there and help those people.”
                  “There's nothing we can do for them. When the shooting started, all the barracks emptied out. People were trying to get out of the compound. If they had remained inside they might have had a chance of getting out alive. The ones that aren't already dead have been bitten and will turn soon. The virus has mutated and the infected are turning faster. The people from Fredericksburg hadn't been here two hours before all of them turned into zombies.”
                  “Didn't they know they were bringing infected people into the compound?”
                  “There was a lady that had a little baby wrapped in a blanket. She was acting strange. Wouldn't let anyone see the baby. I think the kid had already turned and she didn't want anyone to know. That's all I can figure. The rest seemed okay otherwise.”
                  One of the helicopters lifted off. “There he goes. Good riddance. The man is a fucking coward.” The Colonel said.
                  “What now sir?”
                  “You're in
