Because the prevailing winds were from the northwest, Huber had been smelling the fire for almost three hours before the infantry sergeant with the scouting section called over the command channel, “Blood and Martyrs, Captain! This is Charlie One-three-four. Are we supposed to go through this on skimmers? Over.”
Huber switched a quadrant of his faceshield to the view from Floosie, the combat car attached to White Section at the moment. It was like looking into the maw of Hell.
Regimental rocket howitzers hundreds of kilometers to the south in United Cities’ territory had seeded the forest with incendiaries. Each time-fuzed zirconium pellet was capable of burning though light armor. When one landed in old growth forest, the likelihood of it igniting even green timber was three out of five . . . and there were tens of thousands of pellets in the shells, raining down over hundreds of square kilometers. The myriad simultaneous fires had spread till they joined in a firestorm, a towering conflagration that drove its column of smoke through the stratosphere and sucked air to feed it from all sides in a torrent at hurricane velocities.
Everything combustible within the core of the blaze had burned, including the loam. Silica in the clay substrate ran liquid before cooling into slabs of glass colored like the rainbow by trace minerals.
Though the first flush of the fire had burned to a glowing shadow of itself, what remained still shimmered. The boles of the largest trees smoldered, stripped to pillars of carbonized heartwood. Monstrous pythons of smoke and ash eddied, the ghosts of a forest dancing among its bones.
“One-three-four, recover to your carrier vehicle,” Sangrela responded without hesitation. “ASAP, troopers, don’t get into that! There won’t be an ambush in that stuff, not from anything these Volunteers have available.”
He paused, then resumed, “Break. Sierra, button up all hatches. Drivers switch to microwave radar, and exposed personnel lock down your faceshields. Make sure your filters are working before we get into it. We’ll form an echelon perpendicular to the prevailing winds so—”
A route map clicked as an imposed overlay on the lower right corner of Huber’s faceshield. Every trooper in the task force had the same image.
“—that we’re not all driving through the trash the leaders stir up. Six out.”
Floosie must’ve entered the burned area just as Sangrela spoke, because a plume of ash shot skyward two kilometers ahead of Fencing Master. It was like watching the first puff of a volcano gathering its strength.
The fire’d been set to clear the forest between Fort Freedom and the Fiorno Valley at its closest approach, some twenty klicks west of where the river entered the Northern Sea. The tract was well-watered and the foliage was in the green lushness of late spring, so the fire had generally burned itself out to either side of the kilometer-wide swathe seeded with incendiaries. Nothing organic could’ve resisted that dense rain of exothermic metal.
Deseau was driving; Huber heard the hatch cover close over him. Learoyd checked his faceshield and filters with his left hand, then drew up the throat closure of his blouse to get the maximum protection possible without donning an environmental suit.
Tranter was curled up asleep under the forward gun; his head rested on his commo helmet. Huber shook him awake and leaned close to shout, “Get your gear on and locked down, Sarge. There’s going to be a lot of ash and sparks for the next hour or so.”
As Tranter slipped his helmet on with a grin of embarrassment, Huber turned to Captain Orichos. She’d been watching the troopers, but she wasn’t on the Sierra net and didn’t know what was happening. Her expression was neutral, with just enough quirk to the lips to prevent it from being grim.
“We’re going to be going through a burned-out area,” he explained to Orichos over the intercom. He mimed locking down his faceshield rather than touch hers, at present raised. “Your nose filters ought to come down automatically when we hit the smoke, but you might want to push this button here—”
He touched the hinge of his faceshield; the filters dropped over his nostrils.
