Chapter 9 — Supply and Bone

  The letters from Liaodong stopped arriving in the eighth month.

  Wei had been in Korea for two years. He had been in Korea long enough that the smell of it — river mud and pine resin and the faint char of old cookfires that seemed to live in the soil itself — no longer registered as foreign. He thought in the vocabulary of Korean terrain now, the way he thought in any language he had used long enough: automatically, without translation. This ridgeline offers artillery command. This valley compresses advancing formations into a killing front. This ford favors defenders with elevated bank positions.

  He had not been home. He had not received Liaodong's standard officer pay in four months — the disbursement had been interrupted by the same supply route problems that had denied him the reinforcements at Pyokje, and the Liaodong command's dispatch riders were bringing operational orders but not silver. The men had not been paid in two months. They had said nothing about it, which was either a testament to their discipline or to their understanding that complaint produced nothing useful.

  He was beginning to suspect it was both.

  The battalion was at sixty percent of its landing strength. Replacements had arrived twice in two years — twice — and both times the men had come from secondary recruitment pools, undertrained, poorly equipped, carrying weapons that did not match the battalion's standard issue and powder charges that had been mixed to a different formulation than Ru Xiang's gun crews were calibrated for. Both times, Wei had spent three weeks drilling them before he trusted them in formation. The first batch had needed four weeks.

  None of these facts were the most serious problem.

  The most serious problem was powder.

  ---

  "Powder allocation," Wei said at the morning brief.

  The company commanders occupied the remains of a Korean farmhouse three li north of the Han — a stone foundation with the upper walls partially collapsed, a roof that covered two-thirds of the interior, a fire that Gao had established in the uncovered corner with a portable brazier they had been carrying since Pyongyang. Outside, late autumn rain came down on the Korean hills with the patient indifference of weather that had been coming down on these hills for ten thousand years and would be doing so long after this army was gone.

  "Two hundred charges per arquebusier," Gao reported. "Forty rounds per rotation cycle. At current engagement frequency — two major contacts per week — we have approximately three weeks of arquebusier capacity at full rotation."

  Silence in the farmhouse. Not the silence of surprise. The silence of confirmation.

  "After three weeks?" Wei asked.

  "We're a pike army."

  "That's not a tactical problem," Tan Yue said. His voice was flat, factual. "We're good with pikes."

  "We are," Wei said. "The Japanese know it. That is the problem." He leaned forward over the map. "A Japanese commander who calculates that our powder is nearly gone will stop closing with us. He will stop giving us the range we need for the rotation to be lethal. He will pin us at distance — long arquebus lines, maximum volley depth, forcing us to advance through continuous fire across open ground — and he will conserve his own powder, which he has more of, while ours finishes."

  Liu Sheng, who had been looking at the map: "So we either close faster or we find powder."

  "Both," Wei said. "We drill the transition to close faster — I want shield wall to spear hedge in ten seconds, not twelve, because the volley rotation has a twelve-second reload cycle and ten seconds is the inside of the next volley. Every second of margin matters." He looked at Chen Mao. "Chen, I know you think ten seconds is optimistic. I want it anyway."

  Chen said nothing, which was his way of accepting things he thought were difficult.

  "And powder," Wei continued. "There are Korean supply caches in the mountain range north of here — surplus from their own pre-war campaigns, some of which predate the Japanese landing by years. If the caches survived the occupation, they may have Korean-formulation powder." He paused. "Different chemistry from our standard. The burn rate and the priming pan timing will be slightly off. But usable if the arquebusiers adjust their rotation spacing for the different ignition delay."

  "You want to send men into those mountains," Liu Sheng said.

  "I want to send thirty men. Fast. In and out." Wei looked at him directly. "Thirty is the minimum viable scouting force for that terrain. The mountain passes north of here have seen Japanese patrol activity — vedette reports from Yi Yeongno's network, two weeks old. The patrols may still be operating." He held Liu's gaze. "Can you take thirty of your best men and find those caches?"

  Liu Sheng looked at the map. He read it the way he read everything — quickly, completely, already calculating routes and contingencies. "Four nights. There and back, if the caches are where the Korean intelligence says they are."

  "Four nights," Wei confirmed. "You leave tonight. No torches on the mountain approaches. The Korean network will have a guide for you at the northern pass."

  "And if the caches aren't where the intelligence says?"

  "Then you return with what you found and we adjust." Wei straightened. "The rest of you — formation drill through the morning. Powder conservation begins now." He looked at Gao. "Drum codes change."

  Gao's brush was ready. "Change how?"

  "The volley rotation signal — three beats — is now reserved for critical engagements only. At range contacts, we use fire discipline: half-rotation, alternate ranks only. We save full rotation for close engagements where the fire density actually changes the outcome." Wei looked at his commanders. "Your arquebusiers will resist this. They drill full rotation. Half rotation feels wrong to them. Brief them on why."

  "They'll understand why," Liu Sheng said quietly. "They're not stupid."

  "No. They're not." Wei met his eyes. "Tonight, then."

  ---

  *The Mountain — four nights*

  *POV: Liu Sheng — night one and day two*

  The Korean guide's name was Choe Mansik — the same vedette rider who had watched the Japanese fires from the Pyokje ridge with Park Seongjun. He met Liu Sheng's thirty men at the northern pass approach by lamplight, a covered lantern that showed only enough to navigate by, and he communicated in the specific sign language that men develop when they must communicate silently in terrain where sound carries.

  Liu Sheng had not worked with Choe before. He assessed him in thirty seconds: the man moved correctly in dark terrain, placing his feet with the deliberate care of someone who had learned to value silence over speed. He did not look back to check if the column was following. He trusted that anyone assigned to this mission understood that following the guide was the mission.

  Liu's thirty men were the best arquebusiers in Second Company. Not the best shots — though most of them were — but the best at the other things that made arquebusiers valuable in conditions that were not formations on open ground. They could prime a pan in the dark by feel. They could maintain weapons and powder in wet conditions. They had the specific patience of men who had learned that quick movement in dark terrain was an excellent way to break an ankle.

  The first night was climbing.

  Three hours of ascent on a path that existed only in Choe's knowledge of the ground — no cleared trail, no markers, just the memory of the terrain and the ability to read darkness in a specific way. Liu climbed and counted paces and listened to the rain that had begun an hour into the ascent, soft at first and then heavier, the kind of rain that soaked through armor in twenty minutes and then stayed there.

  His powder was triple-wrapped. He checked it twice during the ascent.

  At the second hour, Choe stopped.

  He stopped completely — froze in position, one hand raised in the flat-palm halt signal that needed no translation. The column stopped behind Liu, the stillness propagating backward in the specific way that thirty trained men could go from walking to motionless in four seconds.

  Liu listened.

  Thirty seconds. A minute.

  Then he heard it: voices, to the right, downslope. Two voices, speaking Japanese. The specific cadence of soldiers talking without urgency — sentries at a patrol post, mid-watch, bored. The distance: sixty meters, perhaps seventy.

  He did not move.

  Two minutes of absolute stillness, the only sounds the rain and the distant voices and the controlled breathing of thirty men who had been trained to breathe correctly when stillness was required.

  Then the voices stopped.

  Choe waited another full minute before moving. Then he moved, angling left and up, adding distance from the patrol position, the route now steeper than before but maintaining the separation.

  Liu followed without speaking.

  The patrol post was behind them in ten minutes.

  He did not relax until it was thirty minutes behind them.

  ---

  The second day — daylight, high in the mountain, the rain stopped, the temperature something close to freezing — was the search.

  The cache locations came from a Korean official who had hidden them in the first week of the Japanese advance, when it became clear that the Japanese were moving faster than any defensive preparation could match and that anything left in the lowlands would be taken. He had hidden three caches: one in a natural cave above the third pass, one beneath the floor of an abandoned Buddhist shrine on the fourth ridge's southern face, and one in a collapsed mineshaft that the Japanese had investigated and apparently dismissed as empty.

  The first cache: cave above the third pass. They reached it at mid-morning, Choe leading them to a rock face that showed no sign of human use until Choe moved a specific stone and revealed the cave entrance behind it.

  This story originates from a different website. Ensure the author gets the support they deserve by reading it there.

  Inside: grain, mostly rotted. Medical supplies in sealed ceramic jars, intact. And powder — twenty jin in oilcloth wrapping, the outer cloth deteriorated but the inner layers dry. Liu uncovered it carefully and smelled it. Korean formulation, different from standard Ming powder — slightly coarser grain, a different sulfur ratio that he could identify by nose from his years working with powder. Commander Ru Xiang would need to calibrate for it.

  But dry. Usable.

  He distributed the twenty jin among his thirty men — each man carrying a small additional package, distributed so that no single casualty lost the entire find. He noted this in his field record: *twenty jin, cave above third pass, first cache.*

  The second cache — the shrine — was gone. Not destroyed: looted. The floor had been pried up and the space beneath emptied, the ceramic jars broken and scattered. Japanese, probably. Or Korean civilians, in the first desperate winter of the occupation. Either way, nothing remained. Liu noted it and moved on.

  The collapsed mineshaft was on the fourth ridge's eastern face, a forty-minute traverse from the shrine site, the ground increasingly difficult — scree slopes and ice-filmed rock faces that required hands as well as feet.

  They reached it at mid-afternoon.

  The shaft entrance was collapsed, as reported — a fall of stone and timber covering the original opening, convincing enough that a casual inspection would find nothing worth excavating. Choe pointed to a second entrance, smaller, barely visible behind a growth of pine scrub on the shaft's eastern face.

  Liu sent his smallest man in first.

  Private Ruan Zihai — nineteen years old, narrow-shouldered, with the specific stillness of someone who had learned very young that small people in enclosed spaces were safer if they moved quietly — went through the pine scrub and into the secondary entrance and was gone for ten minutes.

  He came back with his hands covered in old grease and his eyes bright.

  "Powder," he said quietly. "A lot. Sealed in wax and wrapped in two layers of oilcloth inside wooden cases. The cases are stacked." He thought. "I can see twelve cases. Maybe more behind."

  Liu Sheng felt something that was not relief exactly — more like the arithmetic of a problem partially solved. "How much can we carry?"

  They could carry, with thirty men already weighted with weapons and the cache-one powder, approximately two hundred and fifty jin. Ruan estimated the shaft held four hundred jin minimum, possibly more.

  "We take what we can carry and we note the location precisely," Liu said. "The rest we leave sealed in the shaft."

  He had Ruan sketch the shaft entrance from three reference points — two visible peaks on the ridgeline above, one distinctive rock formation below. The sketch went into Liu's coat, against his skin, because the sketch was more valuable than anything else they were carrying.

  Two hundred and fifty jin of Korean powder, distributed across thirty men, plus the twenty jin from the first cache.

  Two hundred and seventy jin total.

  They began the descent.

  ---

  *The ambush.*

  They found the Japanese patrol on the third night's descent, or the patrol found them — the distinction was academic, because the result was the same: a force of approximately forty Japanese soldiers on the approach track, positioned at the narrow section of the descent path where the track squeezed between two rock faces and movement was necessarily single-file.

  Liu Sheng's lead man came around the track's bend and stopped. The man behind him stopped. The column stopped.

  The Japanese arquebusiers at the track junction fired.

  Three men went down in the first volley — the men at the column's head, in the open section between the bend and the junction, where the shot found them before they had time to read what was happening. Liu heard the three impacts and registered them and did not stop moving.

  "Right face — off the track!" His voice, full volume, because silence was no longer the relevant priority. "Into the rock! Get off the track!"

  The column broke right, off the track surface and into the boulder field beside it — not ideal ground, ankle-breaking terrain in the dark, but cover. Men dropped behind rocks and the formation that had been a column became a dispersed defensive line in fifteen seconds.

  The Japanese patrol was positioned on the track. The boulder field was not where they had positioned for.

  Liu assessed from behind a boulder the size of a small house. Forty Japanese, approximately. Arquebuses. They had fired one volley and were reloading. His thirty men — now twenty-seven — were dispersed across the boulder field to the right of the track. His powder was distributed across his men and therefore in the boulder field with them.

  "Half rotation," he said, to the man behind him and the man to his right, and the words traveled laterally. "Fire from cover. Do not move to fire. Do not expose yourself to fire." He raised his voice two degrees. "Bao Suhe — the left flank. Can you see the left flank?"

  Bao's voice from thirty meters left: "I see four of them at the left edge of the track junction. They're trying to move to flank us."

  "Stop them."

  A pause. Then the sound of Bao's section firing — not a rotation, individual aimed shots from covered positions, the specific disciplined use of limited ammunition by men who understood that every shot had to count and that the cover they had was better than any ground they would find by advancing.

  The Japanese flanking movement stopped.

  The engagement lasted twelve minutes. Liu had twenty-seven men and was conserving powder. The Japanese had forty and were in their prepared position on the track. The factors were approximately equal, which meant neither side had the advantage of the decisive engagement they needed.

  Liu made the decision.

  "Withdraw south along the boulder field," he said. "Move by pairs — one pair holds while the other pair moves. Thirty meters, then hold. Do not go back to the track until we are past the junction."

  The withdrawal took twenty minutes and cost four more men — two dead, two wounded who could be carried. By the time the column reformed on the track three hundred meters south of the junction, the Japanese patrol had not pursued. Either they were waiting for dawn, or they had assessed the cost of pursuing into a boulder field in darkness against armed men who knew what they were doing, and had decided the calculation did not favor it.

  Liu counted his men.

  Twenty-three.

  Seven lost — three in the first volley, two in the withdrawal, two wounded being carried.

  He counted the powder.

  Two hundred and forty jin. One package had been lost — fallen from a man who went down in the first volley, irretrievable in the dark on the Japanese side of the track junction.

  Two hundred and forty jin. Twenty-three men. The sketch of the shaft location against his skin.

  "Move," he said. "South. We don't stop until we're below the snowline."

  They moved.

  ---

  Liu Sheng returned to the Iron Crane Battalion's position on the fourth night with twenty-three men and two hundred and forty jin of Korean powder wrapped in oilcloth.

  He came to the farmhouse headquarters directly and set the powder down on the floor in front of Wei and Gao and did not say anything for a moment.

  Wei looked at the powder. Then at Liu. Then at the number of men who had come in behind him.

  "Seven," Wei said.

  "Three in the initial contact. Four in the withdrawal." Liu's voice was the controlled, even voice of a man who has spent four days being composed and is maintaining it because he does not know what comes on the other side of stopping. "One package of powder lost at the contact point. We could not recover it."

  "Show me where."

  Liu produced the sketch of the mineshaft from inside his coat — slightly damp from four nights of body heat and mountain rain, but readable. He spread it on the map table, pointing out the three reference features Ruan had noted.

  Wei looked at it. "How much is still there?"

  "A hundred and fifty jin minimum. Probably more."

  Wei studied the sketch. "I'll send Fang with a larger party in two weeks. Forty men, cavalry screen, different approach route." He looked up from the sketch. "You did the right things."

  Liu said nothing. He was looking at the powder on the floor.

  "The seven names," Wei said. "Give them to Gao tonight."

  Liu nodded. He would give them to Gao. He would also write them himself, as he wrote all of them.

  Wei let him stand quietly for a moment. Then: "Ru Xiang."

  Commander Ru Xiang appeared from the farmhouse's back section, where he had been waiting since Liu came in. He crouched beside the powder and opened the closest package, took a small amount in his palm, looked at it in the lamplight. Rubbed it between two fingers. Smelled it.

  "Korean formulation," he said. "Coarser grain. The sulfur ratio is different — maybe fifteen percent higher. Ignition will be approximately one-fifth of a second slower than standard." He paused. "I can calibrate the gun loads for it. For the arquebusiers, the rotation spacing will need to open slightly — the slower ignition means a slightly longer interval between trigger touch and discharge."

  "How much longer?"

  "A fifth of a second." Ru Xiang looked up. "At full rotation, that means the rotation commanders need to count to the new timing before each rank fires. If they count to the standard timing, they'll fire before the charge has fully ignited and the ball will be undervelocity."

  "Can the arquebusiers be drilled to the new timing?" Wei asked Liu.

  "In three days," Liu said. His voice was steadier now. "I'll drill them myself."

  "Two days," Wei said. "We don't have three."

  Liu accepted this. "Two days."

  ---

  The powder changed the arithmetic but did not resolve it.

  Two hundred and forty jin of Korean-formulation powder bought them, by Gao's calculation, approximately two additional weeks at current engagement frequency — or four weeks at the half-rotation discipline Wei had established. Combined with the standard powder remaining, the battalion had five weeks of arquebusier capacity.

  Five weeks. Against a Japanese force of indefinite size operating on extended supply lines that were also, by Wei's calculation, beginning to feel the strain.

  "The Japanese winter supply situation," Wei said at the next morning brief. He had been thinking about it since the Pyokje withdrawal, and thinking about it more precisely since the mountain raid had made the supply problem specific and quantifiable. "Two years in Korea. Extended lines. The winter strait between Japan and Korea is dangerous — seasonal storms, difficult passage. Their forward supply depots will be running short of powder too."

  "We cannot know their levels," Gao said.

  "We can estimate from their engagement patterns. Look at the last three contacts." Wei spread his operational log on the map table. "At Haengju, the Japanese arquebusiers fired at maximum rotation for four assault waves. At the hill-country engagement two weeks ago, the rotation was reduced — I counted the interval, it was longer than standard. At the ford skirmish last week, they closed with pike infantry rather than maintaining arquebus distance." He looked at his commanders. "Those are not tactical adjustments. Those are powder-conservation adjustments. They are managing their supply the same way we are managing ours."

  Silence in the farmhouse.

  "Which means," Tan Yue said slowly, "that both armies are moving toward a pike engagement."

  "Yes. The campaign's decisive engagement will be close-quarters formation work. Pikes, shields, spear hedges. Whoever has the better formation discipline wins." Wei looked at the map. "And I want to choose where that engagement happens."

  He showed them the valley.

  Six li south of their current position — a natural corridor between two ridgelines, the hills on both flanks steep enough to prevent wide deployment, the valley floor compressing any advancing force into a front of three thousand men regardless of how many tens of thousands they had behind them.

  "They know this valley," Gao said.

  "They know it," Wei agreed. "Which is why I want them to attack up a different valley." His finger moved to a parallel corridor two li west — wider, flatter, the approach looking more favorable to an advancing force. "We hold a visible position here — small force, weak-looking, enough to appear to be our main line. The Japanese command will see it and assess it and decide that the western valley is the better approach." He paused. "Because it is the better approach, if the main formation is actually there. It isn't."

  "A decoy," Liu Sheng said.

  "A decoy." Wei looked around the table. "The real formation waits in the eastern valley, positioned and ready. The decoy fires one volley rotation, draws the Japanese advance, then withdraws south through the eastern approach. The Japanese follow. They enter the eastern valley." His finger traced the route. "Where the formation is waiting, with artillery on both ridges."

  "The decoy force," Zhao said. It was the first time he had spoken. He was looking at the map with the quality of attention that meant he had already calculated the question. "How many. And who commands it."

  "Two hundred men," Wei said. "And I command it."

  The farmhouse was quiet.

  "Commander—" Gao began.

  "I command it," Wei said again, quietly. "Because the decoy's function is to make the Japanese commander believe he is pursuing a defeated main force. That requires the decoy to behave like a defeated main force — which means it must hold long enough to be convincing and withdraw at exactly the right moment. That timing judgment is command judgment. I make it myself."

  He looked at Zhao. "You command the main formation. You know the valley. You know the positions. You know what to do when the decoy comes through."

  Zhao looked back at him without expression. Then: "I know what to do."

  "Gao has operational command if the main line requires something I cannot direct from the decoy position."

  Gao was looking at his notes and not at Wei. His pen was still. Then he picked it up and wrote something.

  "Yes, Commander," he said.

  "We move in two days," Wei said. "Ru Xiang begins positioning the ridge artillery tonight. Two days for the arquebusiers to complete the Korean powder timing adjustment. Two days to position and to wait." He rolled the map. "The Japanese will come. They have been pressing south for a week and they have not found our main position and they are running short of powder and they will come."

  He looked at his commanders in the farmhouse light, in the rain-smell of a Korean autumn two years into a campaign that had cost them half their men and all of their expectation of a short engagement.

  "Iron Crane Battalion," he said. "One more time."

  Nobody answered. Nobody needed to. The phrase did not require an answer. It was a statement of what they were, and they knew what they were.

  The drums spoke outside: two beats, standing down. The rain continued.
