All that summer Vorhees’s men had been looking for it: the entrance shaft to an old copper mine, hidden somewhere in the hills. It was thought that this was one of the hot spots Vorhees had spoken of, a nest where the virals slept. Using old geological survey maps and tracking the creatures’ movements with the nets, they had narrowed their search to the southeast quadrant, an area of roughly twenty square kilometers above the river. Blue Squad’s mission had been one last attempt to locate it before the evac. It was sheer chance that they had; as Peter heard the story from Michael, Blue Squad had simply wandered into it, just before sundown—a soft depression in the earth, into which the point man had vanished with a scream. The first viral who emerged took two more men before anyone could get off a shot. The rest of the squad was able to form some kind of firing line, but more virals swarmed out, braving the last of daylight in their blood fury; once the sun went down, the unit would be quickly overwhelmed, the location of the mine shaft lost with them. The flares they carried would buy them a few minutes, but that was all. They broke into two groups; the first would make a run for it while the second, led by Lieutenant Raimey, would cover their escape, holding the creatures off as long as they could, until the sun went down and all the flares were gone, and that would be the end of it.

All night long, the camp buzzed with activity. Peter could feel the change: the days of waiting, of hunt-and-peck missions in the forest, were over; Vorhees’s men were preparing themselves for battle. Michael was gone, helping to ready the vehicles that would carry the explosives, drums of diesel fuel and ammonium nitrate with a grenade-cluster igniter, known as a “flusher.” These would be lowered by winch straight into the exposed shaft. The explosion would no doubt kill many of the virals inside; the question was, where would the survivors emerge? In a hundred years the topography might have changed, and for all Vorhees and the others knew, a landslide or earthquake had opened an entirely new access point. While one squad put the explosives in place, the rest of the men would do their best to sniff out any other openings. With luck, everyone would be in position when the bomb went off.
