"The Sno-cat," Pitt announced calmly. "Here it comes." He pointed at one of the nearby empty storerooms. "I suggest you and your men get inside quickly before we're all exposed by the headlights."
A terse, quiet command, and twenty seconds later, every man was inside the storeroom, with the door cracked open an inch. The lights grew brighter as the Sno-cat trod its way through the tunnel. Just behind the storeroom door, Pitt crouched with the fuel can clutched in both hands. Behind him, Jacobs stood poised and ready to fire the flare pistol, and behind him, the entire team primed and ready to pour from the storeroom and lay down a hail of lethal fire on the occupants of the Sno-cat or any guards who might be following on foot.
Timing was critical. If Pitt threw the can too soon or too late and the guards inside survived, the entire Special Force team was trapped inside the storeroom like ducks in a closet, and would be wiped out in less time than it would take to tell about it. Jacobs had to be on target, too. A miss and it was all over.
The Sno-cat came closer. Pitt judged its speed at about ten miles an hour. The driver was moving cautiously. Through the narrow slit between the door and frame, he saw no sign of guards following the vehicle on foot. "She's coming too fast for support to follow behind," Pitt reported softly to Cleary. "My guess is they're on a scouting mission."
"They carry four men," Cleary murmured. "I know that much."
Pitt shied his head and closed his eyes to keep from being temporarily blinded by the bright lights of the Sno-cat. It was so close now he could hear its treads crunch against the icy floor of the tunnel. With infinite caution, without using any sudden movement that might catch the eye of the vehicle's occupants, he inched the door open. The front end of the Sno-cat was now close enough to the storeroom that he could hear the muted beat of its engine. Nimbly, focused, and precise, he threw the door open, raised himself to his full height and hurled the gas can into the open compartment of the Sno-cat. Then, without the slightest suggestion of a pause, he ducked to his side and dropped to the ice.
Jacobs was not one to let the grass grow under his feet. He was aiming the flare pistol before Pitt cast aside the door. A millimeter's adjustment and he fired, the shell missing Pitt's head by the width of two fingers a heartbeat after the fuel can sailed into the open Sno-cat and splashed its contents inside.
The interior erupted in a holocaust of flame. The horrified guards, their uniforms ablaze, leaped from the Sno-cat and rolled frantically on the ice to smother the fire. Even if they had been successful, their lives would not have been spared. The men of Cleary's command who had suffered so appallingly from the guards earlier were not in a benevolent mood. They burst from the storeroom and put the guards out of their agony in a flurry of gunfire. The Sno-cat, now hardly identifiable as a mechanical transport, lurched driverless through the tunnel, grazing the slick walls of ice that did little to slow it down.
No time was spent inspecting the death scene. Cleary regrouped his men and got them moving again. Not one man turned and looked back or showed a sign of remorse. They pushed on through the tunnel, anxious to end the nightmare and punish those responsible. With a conscious effort of will, Pitt rose to his feet and leaned on Giordino's rock-strong shoulder for a few steps until his legs worked efficiently again, then set off after Cleary.
When his radio calls to the Sno-cat went unanswered and the sounds of gunfire reverberated from the tunnel, Hugo Wolf assumed the worst. With no more armored vehicles, he had one more hand to play before the Americans reached the hangar and engaged in another free-for-all battle with his eight remaining security guards. He had little confidence in the small army of engineers, who hardly knew how to handle weapons or had the fortitude to shoot down another human, especially a trained professional who was shooting back. What he was about to attempt, Hugo thought morosely, was the last throw of the dice.
He walked over to where Karl, Elsie, and Blondi were conversing with Jurgen Holtz. Karl turned and looked at Hugo, seeing the dark expression. "Problems, brother?"
"I believe I have lost my last armored Sno-cat and four men who were not expendable."
"We've got to hold out," said Elsie. "Bruno is on his way with two aircraft and is scheduled to arrive five hours from now."
"Three and a half hours after the ice shelf breaks free," Holtz remarked. "The activation sequence for the ice machines has begun and there can be no stopping it."
Karl swore softly. "Can we hold out until then?"
Hugo stared at the tunnel leading to the mining facility as if he were expecting an army of phantoms. "They can't have but a handful of men left. If my guards can eliminate them in the tunnel or at least whittle them down to a pitiful few, then between the rest of us, we easily have enough firepower to stop them for good."
Karl faced Hugo and laid a hand on his shoulder. "Regardless of the outcome, brother, I know you will have conducted yourself bravely and with honor."
Hugo embraced Karl, then moved off to join the last of his guards and lead them into the tunnel. They were followed by a tow vehicle pulling a flatcar loaded with a fifty-five-gallon drum and a large six-foot-diameter fan.
The Special Forces team stopped short of the last bend in the tunnel before it straightened and ran another fifty yards into the hangar. A light mist appeared ahead that seemed to grow thicker as it rolled through the tunnel and began to envelop the men.
"What do you make of it?" Cleary asked Pitt.
"Nothing good. We encountered nothing like it when we passed through here with the Snow Cruiser." Pitt raised a finger as if testing for wind. "It's not a natural phenomenon. Not only does it have a strange smell, but it's being sent by some sort of mechanism, probably a large fan."
"Not poisonous," said Cleary, sniffing the mist. "Part of our training is in recognizing toxic gas. My guess is they're laying a harmless chemical on us to screen their movements."
"Could be they're short on manpower and making a desperation play," suggested Jacobs, who came up alongside the major.
"Close up," Cleary ordered his men through his helmet radio. "We'll keep going. Be ready to take whatever cover you can find, should they advance and fire out of the mist."
"I don't recommend that course of action," Pitt warned him.
Cleary simply asked, "Why?"
Pitt grinned at Giordino. "I think we've been here before."
"And done that," Giordino added.
Pitt stared appraisingly at the mist, then put his hand on Giordino's arm. "Al, take one of the Major's men, run back to the tow vehicle, and bring back its spare tire."
Cleary eyes reflected curiosity. "What good is a tire?"
"A little subterfuge of our own."
Minutes later, a tremendous detonation tore through the heart of the tunnel. No flame or swirling smoke, but a blinding flash followed by an enormous shock wave that crushed the confined air before it shot away like a missile through a pneumatic tube. The explosive sound came like a giant clap of thunder before it rumbled away and its echoes slowly faded.
Very slowly, stunned by the sheer density of the shock, his ears ringing like cathedral bells, Hugo Wolf and his eight remaining security guards staggered with numbed senses to their feet and began to advance through mounds of fallen ice, expecting to find nothing but the disintegrated bodies of the Americans. The sheer concussion was far beyond what they'd expected, but their hopes were buoyed into thoughts that their enemy had been eliminated.
