Four hours after midnight on the fourth night, the river fog over the eastern marsh channels thickened until a man standing at the tailboard of the fourth wagon could barely see the ears of the lead mules sixty feet away.
The caravan was preparing for a pre-dawn crossing of the Old Dredger’s Sluice. The last narrow, hundred-yard ribbon of packed shell-marl and sunken timber separating the deep peat marshes from the firmer clay dikes of the lowland farming villages. The four wagons crossed that three-foot-wide raised stone road neck. Then, the ground opened into ditch-lined barley fields within four miles of the village watchtowers, where even a Second Board enforcement squad would hesitate to burn a convoy in broad daylight.
The wooden water gate timbers at the far end of the raised stone road were known to shift during the spring floods. Because of that, veteran driver Pel and young Tomas had walked fifty paces ahead into the fog with a shuttered horn lantern and a hickory sounding-bar to test the beams before bringing the heavy fire-spirit wagon across.
Standing beside the front wheel of the lead barley cart with his forty-pound pack strapped to his bruised shoulders and his ears straining into the damp silence, Seyun heard the sound before he saw a single spark of light.
It wasn’t the splash of a muskrat or the creak of a rotten water gate beam. It was the dull, clear clink of an iron sword sheath striking a brass buckle. Followed half a second later by the muffled thud of a heavy boot heel kicking the shuttered horn lantern out of young Tomas’s hand into the salty mud.
“Commander!” Pel’s deep voice roared out of the fog fifty yards down the raised stone road. Only to be cut short mid-syllable by the flat crack of an iron shield-boss slamming into the old driver’s jaw. “Back the carts! They’re on the dike—!”
At once, twenty resin-soaked pine torches flared to life along the eastern half of the narrow raised stone road. That turned the wet silver fog into a glaring, smoky tunnel of orange firelight.
Out of the curtain of mist marched twenty dismounted men in dark oiled-leather coats and iron-rimmed round shields, advancing two abreast along the three-foot shell-marl crown and the shallow ankle-deep reed margins on either side. They had left their cavalry mounts behind on the northern limestone bluffs. Just then, Ilyra had predicted, and had waded three miles through the night canals from the eastern village road to plug the only exit from the marsh.
Walking at the exact center of the column, four paces behind the front pair of shields, was the tall swordsman in the hammered dark iron half-mask.
His forty-inch Early Bronze war sword rode bare in his right fist. His left forearm—where Ilyra’s spear had pinned his Second Board cuff to the burning cartwheel two days ago—was wrapped tightly from wrist to elbow in black boiled leather strapped with iron buckles, the cut wool sleeve cut off cleanly above the wrist guard.
And stumbling three paces ahead of the front iron shields, with their wrists bound behind their backs in coarse hemp cord and two short-swords pressed directly against the base of their necks, were Pel and young Tomas.
Blood ran in a dark thread from the corner of Pel’s split lip down into his gray beard, and young Tomas’s shirt was torn at the collar where a raider had dragged him up out of the sedge mud. But both wagon drivers were trying desperately to dig their boot heels into the crushed oyster shells to slow the advance. Every time Pel braced his knees, the shield-man behind him drove an iron-shod boot into the back of his hamstring. That forced him two steps closer to the mouth of the island.
Ilyra stood ten paces ahead of the lead barley wagon at the western end of the three-foot raised stone road neck. She lifted her ashwood spear into guard. She had unlashed the twenty-pound practice billets when they broke camp at midnight. That left the seven-foot weapon at its true six-pound fighting weight. Its eighteen-inch steel blade shone cold and bare in the orange torchlight.
Behind the iron half-mask, the one-sleeved Bronze leader’s gray eyes studied her stance on the narrow three-foot ribbon of white shells. And then looked past her bandaged right shoulder at the third wagon, where Seyun’s wet marsh-wort sack still muffled the three copper needles in a low, invisible simmer.
“You have an observant clerk, Student,” the masked leader called out across the thirty yards of narrowing raised stone road, his voice flat and unrushed over the hiss of the pine torches. “He cost me a coat cuff and two days of dry riding on the bluff. Today there’s no ditch to roll your wagon into. No wind to blow your herb-steam into my eyes.”
He raised his left arm in its black leather wrist guard and pointed two fingers at the bound backs of Pel and young Tomas stumbling six feet ahead of his point.
“The raised stone road crown between your boots and mine is thirty-six inches wide,” the swordsman said calmly. “On either side lies four feet of black peat-silt that will suck a man down to his thighs if he steps off the willow mats. We know White Heron Hall’s inner manual as well as the elders who signed our travel warrants in Oran. The Doctrine of the Unbroken Line needs a straight, clear lane to condense its edge. Put down your spear and step away from the third wagon, or drive your straight thrust through your own driver’s spine to reach my shield.”
Behind the lead cart, Custodian Halen let out a thin, whistling whimper. Then he dropped to his knees behind the mule’s rump, covering his head with both arms. Beside the second wagon, Corren, Jarn, and the two guard post pike-guards gripped their ash pikes with white knuckles. They stared in horror at the narrow three-foot ribbon of shells where Pel and sixteen-year-old Tomas fully filled the lane in front of the raiders’ shields.
It was a cold, exactly perfect trap designed specifically for the traditional prodigy of White Heron Hall.
On a thirty-six-inch raised stone road neck with deep peat-mud on both sides, a fighter using The Doctrine of the Unbroken Line had only two choices. Hold the narrow choke point and drive a rigid straight thrust directly through the bodies of the two bound wagon drivers pushed onto her blade, or lower her point and let twenty shield-men walk right over her boots into the wagons.
Had the masked swordsman sprung this trap forty-eight hours earlier, when Ilyra’s hands knew only the sterile straight rail of Master Vane’s courtyard manual, the hard choice would have numbed her spear before a single blow was struck. The Board officer had studied her winter check records in Oran. He knew to the inch how her teachers had trained her to fight. He had built his entire night march around the certainty that White Heron Hall’s prize student couldn’t bend a stroke around a living back.
Twenty yards away in the glare of the torches, Pel spat a mouthful of blood onto the white shells and raised his bruised chin toward the island. “Don’t you look at us, Commander!” the old driver shouted hoarsely, even as the flat of a short-sword struck him between the shoulder blades. “The lad and I knew the road when we signed the roll! Hold the neck and drive through!”
Beside him, young Tomas was trembling from head to foot as the iron shield-rim shoved him forward. His eyes were wide in the torchlight. But the boy bit his lip until it bled and didn’t cry out for her to lower the spear.
Seyun stood two paces behind Ilyra’s left hip at the mouth of the island. He felt the cold wire of Place I under his collarbone pull taut as a bowstring. Not with the brittle, hesitant tension of the cedar-post drills, but with a deep, terrifying stillness that reached all the way down into his lungs.
Already his fingers had slipped the leather toggle of his forty-pound pack. That let the bundle of marsh iron slide silently onto the shells behind the lead wagon wheel. Meanwhile, his right hand closed around the salvaged hickory axle-bar and his left strapped on the iron-rimmed ash buckler.
He didn’t need to ask what she intended to do. Two days of watching her wrists adjust around wicker baskets and oak casks had shown him the exact shape of the answer she had been building in the mud.
Ilyra looked once at Pel’s bloodied beard and young Tomas’s bound wrists approaching the narrow neck of the island. Then she spoke over her left shoulder, her voice barely above a breath: “Seyun—take the left sedge margin with the buckler. Keep the boy’s head down when the water parts.”
