Garrett had built the south wall to hold. He hadn't built it to hold against three hundred.
River stood on the firing step — a raised platform of compacted earth and salvaged timber running along the interior of the south wall, giving defenders a position to shoot from without showing more than their heads and shoulders. Three days of construction. It felt solid until you looked at it from certain angles and noticed the gaps where green timber butted against seasoned, joints that hadn't cured, bracing that worked but wouldn't win any awards. Garrett knew what he was doing. He just hadn't had the time to do it right.
To her left, Petra crouched behind a reinforced section of palisade, her hands working a jammed crossbow mechanism. She stripped the bolt channel, found a wood splinter wedging the rail, flicked it out, and had the thing reassembled in twelve seconds. The crossbow went to Tak, who nodded once and settled it against his shoulder. Tak, the quiet farmer who'd never touched a crossbow until three days ago and now held one like he understood what was at stake.
To River's right, Dara. The scout had positioned herself at the corner where the south wall met the west, giving her sight lines in two directions. Her crossbow was loaded. Her eyes were on the tree line — the dark mass of forest two hundred yards south, extending into darkness that was no longer empty.
"Fenn's put eight shooters on the wall," Dara said, voice low. Low enough that the forest wouldn't hear. "Four on the gate. Twelve in reserve behind the mess hall. Cal's taken four to the water access point — if they come through the stream bed, he'll hear them first."
"That's twenty-eight fighters." River kept her voice down too. "For three hundred."
"Twenty-eight crossbows." Dara corrected the math without correcting the odds. "Plus whatever Garrett's rigged at the gate. He mentioned a counterweight. I didn't ask for details."
River looked south. The tree line was black. The moon gave enough light to see shapes but not faces — favored attackers who knew the terrain, punished defenders squinting into darkness. Above the trees, stars. Zero tactical advantage.
Fenn had positioned himself at the center of the south wall. Not behind the shooters — among them. His crossbow was the oldest in the compound, the wood dark with oil and use, the mechanism smooth from years of loading and releasing. He stood straight. His pale eyes caught the thin moonlight. He looked like what he was: a man who'd done this before, hoped he'd never do it again, and was doing it anyway.
"Movement." Lev, on the southeast corner, forty feet from River. Flat voice. Professional. "Tree line. South-southeast. One hundred fifty yards."
River looked. Saw nothing. Then — there. Not movement exactly. The trees had a rhythm when the wind moved them, a unified sway. What Lev had spotted was a section where the rhythm broke. Trees moving against the wind. Shadows that didn't match their shapes. The darkness rearranging itself into something that wasn't forest.
"I see it," Dara said. "Multiple contacts. Moving in formation. Using the tree cover, staying inside the canopy until the last possible distance."
Fenn's voice cut across the wall, pitched to carry along the firing step without projecting into the open ground. "Hold fire. Nobody shoots until I give the word. First volley has to count — we don't have the bolts for warning shots."
River's hand found the machete. Cal's blade. Its weight against her hip steadied her — connected her to Cal, who was somewhere in the dark at the water access point, waiting for sounds that would tell him whether the stream bed was another approach vector.
The shadows at the tree line multiplied. Shapes detached from the darkness, individual forms becoming visible as they crossed from canopy cover to open ground. No shouts. No war cries. The Crimson Riders came out of the trees the way professionals enter a situation: quietly, organized, treating noise as a liability.
River counted. Lost count. Counted again. The shapes kept coming — a tide of human forms crossing from shadow to moonlight, spreading across the open ground in a wide, deep formation. They weren't running. They were walking. The measured pace of soldiers who knew the defenders couldn't reach them at this range and who weren't going to waste energy on a sprint until they had to.
"Sixty," Dara said. "Eighty. More behind them. The tree line's still producing."
"First wave," Fenn said. His voice hadn't changed. "They'll probe. Find our positions. The main assault follows."
River's throat went dry. She was standing on a wall at night watching hundreds of armed people walk toward her and understanding, with clarity that settled in her gut, that the math didn't work. Twenty-eight crossbows. Three hundred Riders. You could fight hard. You could fight smart. Three hundred was still three hundred.
"River." Fenn's voice, closer than expected. He'd moved along the wall without sound. "When it starts, you stay on the wall. You do not go over. You do not open the gate. Whatever happens below — you stay up here and reload crossbows. Understood?"
"I can fight."
"You can die. And if you die, the immunity dies. Everything Vance has built — the antibodies, the research, the shot at a cure — dies with your blood. You're not a soldier tonight. You're the reason the soldiers are fighting."
River's jaw tightened. She wanted to argue. The same instinct that had driven her to try leaving alone for Marcus, the impulse Cal had called out. She couldn't save everyone. She knew that. Knowing it didn't help.
"Understood," River said.
Fenn moved back to his position. The wall was quiet. Behind them, Sable had moved the noncombatants to the north side — crowded into the mess hall, storage buildings, the infirmary where Vance was prepping surgical supplies with steady hands. Vance's hands never shook, even when surgical supplies meant what they meant during an assault.
The Riders stopped. Two hundred yards became one-fifty. One-fifty became one hundred. At one hundred yards, they halted. A line of dark figures, motionless, facing the wall with the patience of people who had time and numbers on their side.
A voice from the Rider line. Not Harsk — deeper, carrying across the hundred yards with practiced projection.
"Sanctuary compound." Calm. Almost conversational, as if addressing a neighbor across a fence. "General Cain extends a final courtesy. The terms offered at the gorge remain available. Surrender the immune carrier and the doctor. Your people live. This is the last time the offer is made."
Silence from the wall. Fenn hadn't given instruction to respond, and nobody was going to respond without instruction. The discipline held.
The voice waited. Ten seconds. Twenty. Thirty seconds of silence filling the space between the two forces.
"So be it." Still calm. The tone of a man who'd expected this answer. "Your choice is noted."
The line moved.
Not a charge. The Riders advanced at the same walking pace — closing the distance with the discipline Fenn had described in the briefing. They came in a line wider than the south wall, the formation extending past the edges on both sides, wrapping around the corners. The intent was obvious even to River: hit the south wall head-on while flanking elements came around east and west.
"Dara. West corner. Hold it."
"Holding." Dara shifted her crossbow from south to west.
"Lev. East corner. Same."
"Copy." Lev's voice from the far end.
Seventy-five yards. Crossbow range. River could make out individual people now. Armor. Weapons. The red armbands, dark in the moonlight. They carried swords, axes, clubs — the weaponry of a post-Collapse military that used what was available. Some had shields — improvised things, scavenged car doors and bent sheet metal held in front of their bodies.
"Fifty yards," Fenn announced. Still calm. "On my command. Front rank. Pick your targets. Aim for center mass — don't try for heads, don't get fancy. Put bolts into bodies."
River's hands were on a crossbow. Not firing — loading. She'd taken a position behind Tak, feeding bolts into a second crossbow so when Tak fired she could hand him a loaded weapon and take his empty one. Fenn's relay system. Two crossbows per shooter. One fires, one loads. The loader doesn't need to be skilled — just fast.
"Forty yards." Fenn's arm was up. "Steady."
Thirty-five yards. Their faces were visible now — not expressions, not in this light, but the shapes of faces. People walking toward a wall carrying weapons, each one a person who'd survived the Collapse and ended up here, walking through moonlight toward crossbows.
River's hands were shaking. She gripped the crossbow tighter. Loaded the bolt. Set the mechanism. Ready.
"Fire."
Fenn's arm dropped. Eight crossbows released at once — the crack of strings, the hiss of bolts, the sharp percussion that broke the silence.
The bolts hit. Not all of them — some went wide, some went high, the result of shooters firing in darkness with weapons they'd trained on for three days. But enough hit. River saw shapes stagger. One went down in the front rank, folding at the waist, dropping hard.
"Reload! River — bolts!"
River shoved the loaded crossbow into Tak's hands. Took his empty one. Pull the string, seat the bolt, check the rail, done. Six seconds. She handed it to the next shooter. Took their empty one. Loaded. Handed off. The relay working, the rhythm of load-pass-load-pass keeping her hands busy and keeping her mind off what the bolts were doing on the other side.
The Riders didn't stop. The front rank absorbed the volley — dead dropped, wounded crawled, the untouched kept walking. They closed from thirty yards to twenty. Twenty to ten.
"Second volley — fire!"
Eight more bolts. Closer range. More hits. Shooters firing at targets they could now see as people, close enough to watch the bolts strike, close enough to see the blood — dark in moonlight, almost black.
Three Riders down. Four. A fifth staggering with a bolt through the shoulder, still walking toward the wall with wood protruding from the junction of arm and torso. Still walking because stopping wasn't an option.
They reached the wall.
The sound changed. Bolts gave way to the thud of bodies against timber — the wall shaking under dozens of people throwing themselves at it. Hands appeared at the top — gloved fingers, bare fingers gripping the palisade points, the first climbers hauling themselves up.
"Poles!" Fenn shouted. The first real volume in his voice — controlled defense becoming desperate proximity.
Garrett's poles. River had seen them staged along the firing step — long wooden shafts topped with crude metal brackets Petra had bent into hooks. Push poles. Plant the pole against the climber's chest, shove, let gravity handle it.
River grabbed one. Twelve feet of dense wood with a metal end. She planted the bracket against the chest of a Rider who'd gotten both arms over the palisade, whose face was two feet from hers, whose eyes were staring right at her while his hands scrabbled for purchase. She pushed. The bracket dug into his leather armor. His hands slipped. He went backward — an eight-foot drop on the exterior side, violent enough to take him out of the fight.
Another climber. To her left. Petra had a pole and used it with an engineer's efficiency — angle, force, leverage, the climber going back over with a minimum of wasted effort. Tak dropped his crossbow and grabbed a pole and shoved a Rider off the wall with a grunt that carried everything the farmer had never said about defending his home.
The west corner erupted. Dara's crossbow fired — the crack distinct even in the chaos, one shot into the flanking element coming around the corner. One shot. Reload. One shot. Reload. Dara firing with the steady rhythm of someone who knew each bolt had to count because she was alone on that corner.
"West corner's getting heavy!" First time River had heard urgency in Dara's voice. Not panic — the acknowledgment that the west corner was moving from manageable to bad.
"Reserve!" Fenn pointed at the mess hall. Three of the twelve reserves sprinted to the west corner, crossbows up. They moved well — not trained soldiers, but people who'd listened to Fenn's briefing and knew that when he pointed, you ran.
The south wall shook. A rhythmic impact — not climbers. River looked over the palisade: a log. A dozen Riders carrying a stripped tree trunk, using it as a ram. Boom. Boom. Boom. Each strike making the timber groan, making the joints flex and shift, making Garrett's wall fight against forces it could resist but not forever.
"Garrett! Gate status?"
"Holding!" His voice was strained. "The counterweight's loaded. If they breach the gate I can drop it. But it's one use — the mechanism won't reset."
One use. One trick. After that, the gate was just wood and willpower.
The ram hit again. A palisade timber above River's head cracked — a vertical split running down the grain. Through the crack she could see the ram crew resetting.
River grabbed the loaded crossbow from the relay position. Pointed it through the crack. At this range — maybe eight inches — she couldn't miss. The bolt went through and the sound on the other side was wet and she was already loading another bolt because the crack was still there and the ram crew was still there and the wall was still shaking.
"East corner!" Lev's voice, high and cracking. "They're over the corner! Three inside!"
Three Riders inside the perimeter. Past the wall. River spun on the firing step and saw them — three shapes that had climbed the east corner where Lev's single crossbow hadn't been enough, dropping into the compound interior with weapons drawn.
Fenn didn't hesitate. "Reserve — east corner. Push them back. NOW."
The remaining reserves moved. Seven people running toward three Riders, crossbows and makeshift weapons and everything they had. The clash was ugly — chaotic, close-range brawling in darkness. Metal on wood. Wood on flesh. Grunts and screams. Nothing like the crossbow exchanges across open ground.
River watched from the wall, hands full — loading, relaying, because Tak and the wall shooters still needed bolts. She watched the reserves engage the intruders and she watched one reserve go down — a woman, someone River didn't know by name, falling with a small surprised sound that was wrong, the sound of someone who expected to keep standing. The woman hit the ground and didn't get up and the reserves closed around the three Riders and the fight went on without her.
"South gate!" Dara's voice from the west corner. "They're at the south gate!"
A larger group of Riders had broken from the main line and converged on the gate. They hit it with everything — the ram redirected, shoulder charges, axes biting into timber. The gate shook. The secondary bar groaned.
"Garrett!" Fenn's command was sharp.
"Not yet!" Garrett behind the gate. Timing his one trick. Waiting for the moment the gate gave way, when the opening was full of bodies. "Not yet — wait — wait —"
The gate cracked. The secondary bar held but the timber around the bar's mount splintered — the wood failing at the point where the bar met the frame, because the weakest point always went first. Through the gap — a foot-wide crack where the gate had partially failed — a Rider squeezed through. Then another.
"NOW!" Garrett screamed.
The counterweight dropped. River didn't see it — she heard it. A crack of released tension, the snap of a rope or cable, the groan of something heavy falling. Then the result: a horizontal beam, suspended from above, swinging down in a pendulum arc that caught the Riders in the gap at chest height and drove them backward through the opening and into the Riders behind them.
The gap was clear. For a moment. The pendulum swung back, lost momentum, hung limp. Garrett was already there — hands on the gap, timber and nails and improvised bracing, plugging the hole with everything he had.
"Petra!" Garrett's voice, raw. "I need you on this gate. NOW."
Petra dropped from the firing step, ran to the gate, and got her hands on the breach. No visible tools. Just fingers and the knowledge of how things fit together.
The assault continued. The wall held. Barely. The ram crew resumed — boom, boom, boom — each impact widening the crack River had fired through. The east corner was still contested. More Riders were climbing, pressing the corner with repeated pressure. Lev was firing and reloading and firing, past speaking now, running on adrenaline and the understanding that if he stopped, the corner fell.
River loaded crossbows. Her hands were mechanical — pull the string, seat the bolt, check the rail, hand off, take the empty, repeat. A production line.
Her shoulders burned. Her side — the wound from the trail, the gash Vance had sutured — screamed. The stitches pulled with every motion. She ignored it because ignoring it was the only option.
An explosion.
Not an explosion — a collapse. A section of the east wall, twenty feet from the corner, gave way. Not the palisade — the foundation. The soft ground Garrett had warned about, earth that hadn't been properly compacted. The wall section leaned inward, then fell — three palisade timbers going horizontal, crashing into the compound, creating a gap fifteen feet wide and waist-high. What had been a wall was now a pile of fallen timber.
Riders poured through.
Not three. Not five. A wave. The flanking force on the east side had been probing for exactly this — testing the wall, looking for the failure point. Now they'd found it and they exploited it fast and coordinated.
"East wall breach!" Fenn's voice was loud now. The flat register gone. "All reserves to the breach! Everyone!"
River looked at the breach. Riders coming through. Reserves running toward them. The fight about to go from ranged to close quarters.
She looked at the machete on her hip. Cal's blade.
Fenn had told her to stay on the wall. The objective stays behind the wall. The immunity dies if she dies.
But the wall was falling. The Riders were inside. And the reserves — twelve people, now nine, now fewer — were running toward a gap producing attackers faster than defenders could reach it.
River left the crossbow relay. Took the machete from her hip. Dropped from the firing step into the compound.
Fenn saw her. His mouth opened — whatever he was going to say was swallowed by the sound of the east wall coming apart and the shouts of Riders pouring through.
River ran toward the breach. Machete in her right hand. The pain in her side a distant alarm she was outrunning because the gap was closer than the firing step and the people in the gap needed every body that could hold a weapon.
She reached the breach with the first reserve group. A Rider came through — big man, armored in leather and scavenged metal, swinging a short sword at the first person he saw. That person was River.
She ducked. Cal's training — not technique, instinct. The sword passed over her head and she came up inside his reach and drove the machete into his thigh. Not trying to kill — trying to stop him, put him on the ground before he got farther into the compound. The blade hit meat. He buckled. River pulled it free and stepped over him to face the next one through the gap.
The next one was faster. Younger. He had a club and he swung it sideways at her ribs. She got the machete up to deflect but not block — the club glanced off the flat and continued into her left arm with enough force to numb it from elbow to fingertips. Her arm dropped. She switched to a one-handed grip and drove the machete forward into the young Rider's stomach. He folded around the blade. His face was close enough to see his eyes, close enough to see the surprise — the expression of someone discovering that his body had stopped cooperating.
River pulled the machete free. He fell. Behind him, another. And another. The breach kept producing them, each one meeting the defenders in the narrow space where the fallen timbers created a bottleneck.
The bottleneck saved them. The fifteen-foot gap should have been wide enough for Riders to pour through and overwhelm them. But the fallen timbers created obstacles, tripping the attackers, forcing them to climb over debris, slowing the wave into a trickle that the defenders could meet one or two at a time.
River fought. Her left arm came back — pins and needles, partial function, enough to grip two-handed. She stood between two fallen timbers and met each Rider who climbed through with Cal's blade. She wasn't good. She wasn't skilled. She was fast and desperate and willing to take hits a trained fighter would avoid because a trained fighter had options she didn't. Her only option was standing in this gap and not moving.
Dara appeared beside her. The scout had left the west corner — whether it was covered or fallen or she'd decided the breach was more critical, River didn't know. Dara's crossbow was replaced by a short blade, her movements precise and practiced, each stroke a decision rather than a reaction.
"Back!" Fenn's voice from the wall. Directed at the breach, at the line of defenders. The old soldier had jumped from the firing step and was organizing them into a line across the gap. "Form up! Hold the line! Don't chase — hold!"
The line formed. Ragged. Imperfect. River, Dara, Tak, three reserves, Lev who'd abandoned the corner and brought his crossbow to point-blank range — standing shoulder to shoulder, doing the work the timber wall no longer could.
Fenn stood behind the line. Not fighting — commanding. Crossbow covering the gap, voice directing the defense, reading the battle with the experience of decades.
The Riders kept coming. One at a time. Two at a time. The defenders held — each attacker met by blades and bolts at ranges where accuracy didn't matter. The gap was a meat grinder and neither side was willing to stop feeding it.
River's arms were dead weight. Her side was screaming — the stitches had torn, she could feel warm wetness spreading under her shirt. Her left arm throbbed with each heartbeat. Her right hand was locked around the machete handle in a grip that would need to be pried open later.
If there was a later.
A horn sounded. From the south. A single note — low, long, carrying over the fighting, over the wall, over everything. It held. Stretched. Faded.
The Riders at the breach stopped coming. Not all at once — the flow thinned, then stopped. The last Rider through met Dara's blade and went down. After him, nobody. The gap was empty. The breach was quiet. The defenders stood in their ragged line with weapons raised and no one was climbing through.
From outside — the south side — retreat. The organized withdrawal of a force pulling back, boots on ground diminishing, the Rider formation disengaging from the wall and the gate and the corners, moving toward the tree line.
The horn sounded again. Farther away. The recall.
Silence fell. Not real silence — breathing, groaning, the creak of damaged structures. But the fighting was over. The ram had stopped. The climbers had stopped.
River lowered the machete. Her arms dropped to her sides. The blade hung from her right hand, the edge dark with blood that wasn't hers.
Fenn moved through the line. Checking. Counting. His face gave nothing away. Processing.
"Casualties." His voice was quiet. "Report."
The numbers came in. Three defenders dead. Seven wounded, two seriously. A woman River didn't know. A man from the reserves. A young person who'd been at the east corner when the wall collapsed. Three dead and seven wounded out of twenty-eight, and the assault had been a probe, and Fenn was looking at the south tree line with an expression River recognized from Marcus's face when things were bad.
The tree line was dark. The Riders had retreated into it. Three hundred minus however many had fallen — maybe thirty or forty at best.
"They'll come again," Fenn said. He was looking at the breach, the fallen timbers, the gap that needed repair, the east wall that needed rebuilding in the hours or minutes before the second assault. "That was the test. They found the east wall. They found the foundation weakness. Next time they hit the east wall with everything."
"Can we hold?" River asked. Her voice was raw — exertion and shouting and fighting had stripped it thin.
Fenn looked at her. His pale eyes were steady. The answer was in his face before he said it.
"We hold until we can't," Fenn said. "Then we figure out what to do with what's left."
He turned to the breach. Started organizing. Timbers to reset. Positions to fill. Wounded to Vance. Dead to cover. Reconstruction beginning while the tree line watched and the thin moon hung overhead and the night wasn't finished.
River stood in the gap. Machete in hand. Three bodies nearest her — two Riders and the reserve woman whose name River had never learned, lying three feet from the Riders she'd died fighting.
River looked at the woman. Looked at the Riders. The blood was the same color on everyone — dark in moonlight, almost black.
From the south gate, Garrett's voice. Quiet. Broken. "The gate's patched. It won't hold another ram. If they bring the ram back—"
He didn't finish.
River cleaned the machete on her pants. Sheathed it. Walked to the east wall breach where Fenn was organizing the repair. Her hands found timber. Her arms, which were lead and fire, lifted. She carried a section of palisade to the gap, set it in place, and went back for another.
The work continued. The night continued. Somewhere in the trees, three hundred minus thirty were resting and resupplying and getting ready to do it again.
The first horn had been the recall.
River wondered what the second one would sound like.
