The rider came out of the reeds before the sky had found its color.

He was on foot. The final channel had narrowed too much for a horse, and he had left his animal with Bayan’s team at the route’s last marked point. He came through the reed wall wet to the chest and found the relay rider waiting there, and the relay rider brought him straight to Batu’s position.

"Ford’s confirmed." the man said.

His breath was hard from the wading. "Bayan marked the full route. The far bank’s clear."

"How far is the ford from the last channel exit?"

"Two hundred meters of open water. Firm bottom through the middle section."

He wiped his face with the back of his arm. "We crossed it twice in the dark without losing footing."

Batu looked at the reeds in front of him. It was slightly less dark now, the sky behind it beginning its first movement toward gray.

He looked at the relay rider beside him. "Tell Torghul."

Torghul POV

The order reached him while his riders were already pressed against the reeds, the formation in the cold dark for the past hour. He gave the hand signal to the first column jaghun commander, and the tumen moved.

The reeds took them within twenty strides.

Torghul was at the column’s head. The stems rose on both sides within the first channel and rose further as the passage narrowed, until the sky above was a strip of lightening gray and nothing else.

The reed stems against the horses’ flanks made a dry friction sound as the riders moved through them, nothing like the open-steppe sound of a marching force. The percussion of hooves that had been carrying across open ground compressed in the channel terrain and went nowhere.

The tumen behind him was audible differently, closer, denser. The column’s depth collapsed into the channel’s acoustic space. 𝒻𝓇𝑒𝘦𝘸𝑒𝒷𝓃ℴ𝑣𝘦𝑙.𝒸ℴ𝘮

Bayan’s markers were at eye height. Felt strips tied along the channel walls, visible in the pre-dawn gray as pale rectangles against darker vegetation. The lead riders read them without slowing.

The channel bent twice, both bends shallow, both passable at a careful walk without losing direction. At the second bend the ground underfoot changed, firmer, the channel bottom transitioning from reed-root mud to compacted silt, and the horses noticed it through their feet and walked with more certainty.

The channel opened.

The Volga was in front of them. Wider than what they had prepared for, and the smell reached them first, open river water, cold in a way the enclosed vegetation smell of the channels was not.

Torghul’s lead riders moved to the ford without stopping. The first horse went in to the fetlocks, then the knees, the rider holding his bow clear of the surface. The ford bottom was firm.

The water rose to the horses’ bellies at the crossing’s deepest point, the current pressing steadily from the south, and then the bottom rose and the far bank came up from the water and the horse was out.

Torghul crossed and turned, reading the ground.

Open pasture land, grass short and pale, cut by the occasional dark line of a drainage ditch. The pre-dawn light was enough for terrain without detail. Ahead to the northwest, a pair of earthwork rises on the horizon, low, man-made, the outline of fortified positions.

Between here and there, flat open ground with no cover. A torrent of thin smoke rose from a point north of the earthworks, too small for a signal fire, the right size for a garrison’s overnight hearth.

The first mingan was organizing on the bank behind him, riders coming out of the ford wet from the knees down, horses shaking water from their coats, the formation spreading on the flat ground without instruction. The second column had begun its crossing at the ford’s southern bank.

He looked at the earthworks and the smoke, then at the distance between the ford and the nearest outer position, then east for the main body’s crossing.

Batu crossed with the second wave of the main body.

Daichin took the ford without hesitation, the animal’s size meaning the water rose no higher than its lower chest. The current pressed from the south and Daichin moved through it with the straightforward ease of a horse that had crossed rivers before and found nothing remarkable about this one.

The left bank came up, gravel solid under the hooves, and Batu rode out of the water onto Bulgar soil.

Torghul was ahead at the formation’s organizing point. He turned when Batu reached him. "Two outer positions confirmed from here."

He continued, "The smoke’s from the near one. They don’t know we’re here yet."

"How long has it been burning?"

"It was there when I came out of the ford. Overnight fire."

He looked north. "Chaidu’s mingan already moved. He took his vanguard north ten minutes ago."

Chaidu POV

He had two hundred riders moving at a canter through the open ground north of the ford, spread across a wide front with the outer pairs reading the flanks. The pre-dawn light was enough for distance work. The earthwork positions ahead were darker shapes against the lightening sky, and the garrison smoke was directly north, maybe two kilometers out.

They found the Bulgar defenders a kilometer short of the first earthwork.

Five hundred of them, roughly, moving south in a loose body, garrison troops, foot and some mounted mixed together. The infantry were carrying spears and short bows and wearing the padded coats of men who guarded earthwork positions in peacetime.

The cavalry, maybe eighty riders, were running ahead of the foot in an attempt to organize the engagement at range.

Someone in the watchtower had seen something and the garrison had come south to find it, which meant they’d seen the ford movement at distance in the dark and understood enough to respond but not enough to understand what they were responding to.

Five hundred men walking toward an unknown contact was not the same as five hundred men staying inside earthworks.

They had made the wrong choice.

Chaidu raised his arm without slowing. The signal went down the line and his riders opened their spacing, the front spreading wider, composite bows coming off shoulders across the formation.

The Bulgar cavalry saw the spread for what it was and turned their horses hard, calling back to the infantry. The foot soldiers heard the cavalry retreating, and some of them stopped and turned north, and then more of them ran, and by the time the first Mongol volley came down the line was already fracturing.

The arrows went in flat at a hundred and twenty meters.

The foot soldiers in the front rank had no shields worth the name out here in the open, away from their earthwork walls, and the first volley cut through the leading edge. Men went down in cries of pain and terror and the ones behind stumbled over them and the panic spread faster than any order could move through a garrison in the dark.

Chaidu’s line closed to eighty meters and released the second volley, then sixty for the third. The foot soldiers still standing and facing south were fewer with each release.

A man in a padded coat took a shaft through the throat and sat down slowly in the grass, his body lifeless. Another went down with one through the upper chest. His body folded forward and the spear in his hand hit the ground first and then his face.

The Bulgar cavalry had already broken north in a mass, maybe forty riders left from the original eighty, their horses pushed hard for the earthwork’s outer gate. Four of them split from the group when the outer riders of Chaidu’s line curved north to cut them off.

Two went west, which took them away from the tower and out onto open ground with no obvious destination. One stayed with the main group for the gate. One went east.

Chaidu saw the rider going east before his own eastern-flank man did. The man was low on his horse’s neck, pushing straight for the tree line, not looking back. The trees were two kilometers east, maybe less.

The written order was specific and Chaidu had read it twice before leaving Sarai. He turned his attention north and let the rider go.

The forty going for the gate were running too fast for his line to intercept before they reached it. He looked at the distance and the numbers and pulled his outer riders back to screen position.

The infantry was still in the field.

The ones who hadn’t run were pressed together in a loose group of perhaps two hundred, their mounted men gone and their orders with them.

They were holding spears and looking at Chaidu’s riders at sixty meters and arriving, the terror and fear was as clear in their eyes as it was in their shaking hands.

Some of them threw their spears down and held their hands out from their sides. Some of them were already on their knees.

Chaidu pulled his formation back to screen spacing and held them there.

The earthwork gate ahead was closed now. The riders who had made it inside would be at the signal fire within minutes, and there was nothing Chaidu’s vanguard could do about that from here, and he had not been given orders to attempt it.

He watched the top of the watchtower.

The signal fire went up before the sky had finished its turn from gray to pale. It caught in a single burst, dry fuel prepared and waiting the way garrison signal fires were always prepared, and rose above the tower’s rim in a column of orange and black smoke that had nothing to do with a cooking hearth.

It would reach the next position south, and the one beyond that, and Suvar’s walls themselves in clear autumn air.

Chaidu turned his horse and looked back toward the ford, where the main body was still coming over in continuous waves, Torghul’s full tumen forming on the left bank behind him.

Everything between here and Suvar that could receive a signal now knew there was a Mongol army on the left bank.
