Chapter 128: Deployment of the Heavy Mech Vanguard

The diesel exhaust plumes rising forty-four miles south of the continental shelf flattened against the gray, freezing belly of the morning overcast.

Eight heavy pontoon barges, each two hundred feet long and welded from three-inch ballistic plate, formed an aggressive forward echelon. Unlike the stationary drilling platforms broken by Thorne hours before, these barges were driven by twin steerable hydro-jets that churned the dark swells into frothing corridors of white foam at twenty knots. Upon each deck crouched a Colossus Mark-IV combat unit, their reverse-jointed titanium legs chained to the deck plates by explosive release shackles.

High above the salt spray, slaved to General Vance’s primary neural bus aboard the distant super-dreadnought, Major Briggs held the physical joystick inside the lead frame.

His visor display blinked with green vectors tracing the underwater contours of the approaching continental shelf.

"All units, lock acoustic suppression sirens to ninety fathoms," Briggs barked over the tactical link, his jaw clenching as the high-pressure hydraulic pumps behind his seat whined in his ears. "The Sovereign relies on necrotic infantry clinging to the hulls. The moment we cross forty-three miles, radiate the water column with four thousand watts of pulsed frequency. Boil their auditory canals before they touch our rudders."

Along the outer sponsons of the eight barges, heavy cylindrical transducers plunged twelve feet into the ocean.

A low, nauseating hum tore through the dark water.

The acoustic weapon was not loud to human ears above the surface; below the waterline, it produced a continuous twenty-kilohertz pressure wave that pulverized organic tissue, turning schools of migrating mackerel into drifting clouds of shredded scales and bloody pulp within three hundred yards.

Through the fluorocarbon immersion fluid sixty miles behind the lines, General Vance’s consciousness monitored the telemetry.

The eight mechs moved across his sensory awareness like extensions of his own limbs. He could feel the tension in their drive sprockets, the temperature of their twin sixty-millimeter railgun breeches, and the cold bite of the headwind buffeting their depleted uranium mantlets.

"Briggs," Vance’s thought manifested in the major’s audio receiver, cold and level as a carpenter’s plumb line. "The basalt ridge forty miles out has four sunken hulls welded across the central choke point. That is where Renan dropped his acoustic markers. Do not look for sentries on the decks. His dead sleep in the bilges."

"Understood, General," Briggs replied, toggling the arming sequence on his twin rail cannons. "We have the forty-five-mile marker in our sights. Crossing the threshold now."

The lead barge sliced across the invisible boundary drawn by Renan’s broadside the previous morning.

The sea did not erupt in dragon-fire. There were no columns of boiling mud or shrieking ghosts.

Four miles ahead, standing atop the barnacle-encrusted bow of a scuttled British frigate that breached the surf like a jagged black fang, Renan stood with his hands tucked loosely inside his woolen pockets.

The offshore wind whipped his wet black hair across his forehead, his violet pupils dilating as he tracked the incoming wake of the eight mechanized platforms. Beside him, Shadow Knight Arthur rested the flat of his silver-black claymore against his iron thigh, his crested helm tilted slightly toward the whining hydro-jets.

"They bring sound to clear the path, Sovereign," Arthur murmured, his metallic cadence carrying the dull echo of submerged armor. "The Church used similar acoustic bells during the Baltic clearance. It disrupts the connective soul-threads of lower constructs before they can solidify kinetic mass."

Renan did not draw the void dagger from his waist.

He looked down into the black, churning water swirling past the frigate’s rusted draft marks.

Through the bottom of his boots, he could feel the cold, impatient hunger of six hundred shadow skirmishers swimming in tight, concentric circles forty feet down, their slender forms gliding through the acoustic pressure waves like predatory sharks that did not possess ears to burst.

"Sound requires water to travel, Arthur," Renan said softly, his voice cutting through the thrum of the approaching American turbines. "Let us see how loud their sirens sing when the water is turned to oil."

Renan lifted his right boot, bringing the heel down onto the rusted steel capstan of the bow.

[Skill Activated: Abyssal Desiccation Surge] [Target: Sub-Surface Water Column, Grid Tango-Four] [Infused Mana: 3,200 Sovereign Density]

The rolling swells between the frigate and the approaching American vanguard did not part.

The top twenty feet of the ocean surface thickened, the clear salt water darkening into a viscous, tar-black sludge that swallowed the white foam of the waves. The high-frequency acoustic waves radiating from the American transducers hit this newly dense fluid barrier and died instantly, their energy converted into dull, muffled vibrations that barely stirred the kelp beds.

Aboard the lead barge, Major Briggs stared at his sonar waterfall display as the clear green contours blurred into solid, static snow.

"Telemetry lost," the acoustic operator yelled from the small deckhouse. "The medium density jumped by eight hundred percent. The transducers are cavitating in heavy slurry! The hydro-jets are dragging!"

The eight steel barges slowed abruptly, their sterns rising as the thick black water choked their intake grates with fibrous, necrotic sediment.

"Blow the shackles," Briggs shouted, slapping the emergency pneumatic release on his center console. "Colossus units, deploy to the pontoons! Engage secondary track drives!"

The explosive bolts along the deck plates detonated in eight sharp, concurrent cracks.

The sixty-ton Colossus frames stood upright, their reverse-jointed legs planting six-foot serrated steel pads onto the barge sponsons. Their rotary railgun turrets snapped forty-five degrees forward, three-inch depleted uranium penetrators clacking into the feed chutes with mechanical finality.

Before the first railgun could charge its magnetic coils, the black sludge beneath the barges surged upward.

Six hundred shadow skirmishers tore through the surface in absolute, terrifying silence.

They were not climbing ladders. They rose out of the tar-like brine like black needles of star-metal, their long, serrated boarding pikes forged from cold-compressed abyssal ice.

They did not strike the armored cockpits where the pilots sat behind six inches of glass. They dove beneath the sponsons, driving their pikes directly into the exposed hydraulic steering linkages and the flexible rubber fuel lines feeding the secondary generators.

"Fire point-blank!" Briggs screamed, his mech’s left railgun depressing toward the deck plating beneath its own sabaton.

The sixty-millimeter magnetic rifle fired with a concussive roar that shattered the forward observation windows of the barge deckhouse.

A three-inch tungsten slug plowed through two shadow skirmishers, tearing their liquid silhouettes into ragged shreds of dark mist, and punched a five-foot crater clean through the steel barge deck into the sea below.

Yet the severed mist did not dissipate.

Under the passive aura of Arthur’s Silver Vanguard, the torn shadows reassembled themselves in less than half a second, their icy pikes plunging into the mech’s exposed ankle actuators, severing the high-pressure hydraulic conduits with a violent hiss of escaping fluid.

The sixty-ton mech tilted twelve degrees to the left, its knee actuator seizing as red warning lights flashed across Briggs’s visor.

Through the immersion tank sixty miles away, General Vance felt the sudden loss of pressure in unit one’s left leg. He did not blink. He did not order a retreat.

His mind bypassed Briggs entirely, seizing manual override of the remaining seven Colossus frames.

"Form wedge formation," Vance’s thought commanded, his will overriding the panicked inputs of the human pilots. "Drop the stern anchors to the seabed. Lock the spades. Cease anti-infantry fire."

The seven operational mechs moved in inhuman, mathematical synchronization.

Their heavy four-legged bodies swung inward, back to back, forming a ring of interlocking steel shields along the central barges. Their fourteen twin railgun barrels did not aim down at the swarming shadow skirmishers climbing the hulls; they swung sixty degrees upward, aiming past Renan’s lone figure on the frigate toward the gray clouds above the Nero Trench.

"General?" Briggs wheezed through his headset, his hands trembling over his dead controls. "What are we aiming at?"

Inside the immersion tank on the USS Titan, Vance’s lips parted beneath the breathing mask, cold and unyielding.

"We are not fighting the dogs, Major," Vance thought, his direct link to the three Gungnir satellites in low earth orbit clicking into the final firing countdown. "We are dropping the roof."

Above the low overcast, sixty-two miles straight up, the primary revolver bay of the first Gungnir orbital platform rotated sixty degrees.

A twenty-foot cylinder of solid, cold-pressed tungsten dropped from its magnetic launch rail into the vacuum of space, falling toward the Eastern Strait at Mach 9.
