Not everyone was so dedicated to studying his aberrations. An unruly physician named Clifford insisted that healing came first. Against the researchers' wishes, he tried flushing Branch's system with oxygen, and irradiated him with ultraviolet light. At last Branch's metamorphosis eased. His metabolism and strength tapered to human levels. The calcium outgrowths on his head atrophied. His senses reverted to normal. He could see in sunshine. To be sure, Branch was still monstrous. There was little they could do about his burn scars and nightmares. But he was better.
One morning, eleven months after arriving, ill with daylight and the open air, Branch was told to pack up. He was leaving. They would have discharged him, but the Army didn't like freaks with combat medals bumming around the streets of America. Posting him back to Bosnia, they at least knew where to find him.
Bosnia was changed. Branch's unit was long gone. Camp Molly was a memory on a hilltop. Down at Eagle Base near Tuzla, they didn't know what to do with a helicopter pilot who couldn't fly anymore, so they gave Branch some foot soldiers and essentially told him to go find himself. Self-discovery in camouflage: there were worse fates. With the carte blanche of an exile, he headed back to Zulu Four with his platoon of happy-go-lucky gunners.
They were kids who'd given up shredding or grunge or the 'hood or Net surfing. Not one had seen combat. When word went out that Branch was going armed into the earth, these eight clamored to go. Action at last.
Zulu Four had returned to as much normalcy as a massacre site could. The gases had cleared. The mass grave had been bulldozed flat. A concrete marker with an Islamic crescent and star marked the site. You had to look hard to still find pieces of Branch's gunship.
The walls and gullies around the site were cored with coal mines. Branch picked one at random and they followed him in. In later histories, their spontaneous exploration would become known as the first probe by a national military. It marked the beginning of what came to be called the Descent.
They had come as prepared as one did in those early days, with handheld flashlights and a single coil of rope. Following a coal miner's footpath, they walked upright – safeties off – through neat tunnels trimmed with wood pillars and roof supports. In the third hour they came to a rupture in the walls. From the rock debris spilled onto the floor, it seemed someone had carved his way out from the rock.
Following a hunch, Branch led them into this secondary tunnel. Beyond all reckoning, the network went deeper. No miner had mined this. The passage was raw but ancient, a natural fissure winding down. Occasionally the way had been improved: narrow sections had been clawed wider, unstable ceilings had been buttressed with stacked rock. There was a Roman quality to some of the stonework, crude keystones in some of the arches. In other places the drip of mineral water had created limestone bars from top to bottom.
An hour deeper, the GIs began to find bones where body parts had been dragged in. Bits and pieces of cheap jewelry and cheaper Eastern European wristwatches lay on the trail. The grave robbers had been sloppy and hurried. The ghoulish litter reminded Branch of a kid's Halloween bag with a rip in it.
They went on, flashing their lights at side galleries, grumbling about the dangers. Branch told them to go back, but they stuck with him. In deeper tunnels they found still deeper tunnels. At the bottom of those, they found yet more tunnels.
They had no idea how deep it was before they quit descending. It felt like the belly of the whale.
