The cavalry had gone beyond the springs.
Lucius turned back toward the map before the meaning of that movement could harden into assumption. The river, the bridge, the northern pasture, and the east-bank road remained marked in wax and carved wood, but the line that mattered now lay behind them: the road descending east from the ridge toward the earlier Roman positions, the water sources, the wounded convoy, and the supply wagons that made holding the high ground possible for more than a single day.
Marcus followed his gaze.
"The convoy left before dawn," he said. "The worst wounded were sent east with the dead and the reserve stores."
"Where are they now?"
"Past the second spring, if they kept their planned pace. The lighter wagons and the wounded from Varro's force remain nearer the ridge."
Cassian looked toward the eastern slope. "The riders may be going after the first convoy."
"Not to take it," Lucius said.
The Carthaginians had not sent enough cavalry to seize a guarded Roman wagon train if the escorts held formation and refused to chase. They had sent enough to watch the routes, count the guards, identify where water parties crossed the road, and decide whether a convoy carrying wounded could be slowed, turned, or made to call for reinforcement.
Every answer Rome gave would reveal how much strength it could spare from the ridge.
Marcus studied the eastern route on the map. "They may also be looking for a way back around us."
"Yes."
"The road splits twice before the first valley."
"Yes."
Cassian's expression tightened. "Then they do not need to strike the convoy. They only need to make it stop."
Lucius nodded.
A halted convoy became a visible problem. Wagons gathered. Guards formed around injured men. Water ran low. Messengers rode back toward the ridge. Roman officers had to decide whether to send cavalry, infantry, or both eastward to clear a threat that might never become an open attack.
Hamilcar did not need to break the road.
He only needed Rome to begin defending it in pieces.
"Send riders to the convoy," Lucius said. "Not by the main road."
Cassian looked toward him. "The old charcoal route?"
"Yes. Two patrols. One follows the higher ridge south of the road. The other moves north through the dry terraces. They are not to ride beside the convoy unless contact has already begun."
Marcus understood. "You want them to find the cavalry screen, not become another part of it."
"Exactly."
Lucius turned toward the staff officer nearest the awning entrance.
"Tell the eastern water guards to remain in place. They do not move toward the convoy unless riders approach the springs directly. The reserve centuries hold the north road. The main standards remain visible above the bridge."
The officer saluted and moved quickly into the camp lanes.
Cassian remained by the map.
"If Hamilcar is looking for the convoy road, he may not care whether he finds it tonight," he said. "He may only want us to know he is looking."
"Yes."
"And if we send patrols quietly, he learns less."
"He learns something anyway."
Cassian gave him a tired look. "That is becoming your answer to everything."
"It is becoming the field."
Outside the command awning, the Roman ridge had begun settling into evening order. The exhausted men from Varro's bridgehead had returned from the river trees and were being divided between the treatment area, the repair line, and the units still fit to hold the perimeter. Their armor carried mud from the shallows and dark smears from the close fight in the pasture. Some men sat beneath the awnings while medics cut away soaked cloth and checked wounds that looked smaller until dried blood was washed away. Others stood silently beside their shields, waiting for replacements to arrive before allowing themselves to rest.
The road behind them did not permit the army to forget the river.
The river did not permit the army to forget the road.
A runner arrived from the southern water route before Cassian could leave.
"Tribune," he said, "the spring watch found hoof prints on the eastern side of the charcoal pit. Fresh. Six riders at least. They did not approach the water."
"Which way did they go?"
"North, toward the old road."
Lucius looked at Cassian.
"They are crossing between the routes," the centurion said.
"Yes."
"They are looking for the convoy without showing themselves on the convoy road."
"Or they want us to believe they are."
Cassian exhaled through his nose. "I regret asking."
Lucius pointed toward the northern ridge line beyond camp. "Take twenty mounted men. Do not follow the hoof prints directly. Ride north until the old road bends toward the terraces, then cut east behind it. Find whether the riders crossed the convoy's path or merely marked it."
Cassian nodded.
"And if I find them?"
"Count them first."
"That remains unsatisfying."
"It remains useful."
Cassian secured his helmet and left the awning.
Marcus stayed beside the map, watching the lantern flame bend beneath a faint evening wind.
"You are holding the ridge with fewer men than Hamilcar wants you to think," he said.
"Yes."
"And moving riders east with fewer men than he wants you to send."
"Yes."
Marcus looked toward the bridge road, where the Roman standards still stood against the falling light.
"He may not strike tonight."
"No."
"But he will make every watch wonder whether he will."
"Yes."
The general considered the river position beyond the western lowland. Carthaginian fires had begun appearing near the northern pasture again, not brightly enough to reveal the full reoccupation of the ground, but clearly enough to show that Hamilcar had not treated the day's fighting as a temporary inconvenience. The bridge remained guarded. The settlement roads remained active. Work continued along the western rise behind the storehouses.
The enemy had not been pushed from the water.
Rome had only made him work harder to hold it.
Marcus rested one hand against the edge of the table.
"Then what do we do tonight?"
Lucius looked toward the eastern road disappearing beyond the ridge.
"We make sure the road does not become another river."
The first patrol returned after sunset.
It came from the northern terraces, where the old road passed between low stone walls and fields long gone dry. The lead rider's horse was sweating heavily, though no blood marked its flanks. The patrol had not been attacked. That was clear before the man dismounted.
It had been watched.
"Tribune," the rider said. "We found the cavalry crossing north of the spring route."
"How many?"
"Eight confirmed. More tracks beyond the wall. They split into two groups."
"Toward the convoy?"
"One group followed the east road. The other moved north toward the old quarry path."
Marcus leaned toward the map. "The quarry path reaches the convoy road farther east."
"Yes," Lucius said.
The rider continued. "We found signs of a Roman messenger passing through shortly before them. One horse. Fast pace."
"Did the cavalry follow?"
"Not immediately. They stopped at the road and waited."
Cassian was still out with the second patrol. Lucius looked toward the dark eastern ground.
The riders were not simply scouting.
They were choosing moments when Roman movement could be seen, then allowing those movements to continue long enough for the meaning to travel elsewhere. A messenger rode east. The cavalry saw him. They did not chase. They waited at the road.
Someone farther along the route might be prepared for the message before it arrived.
"Send another messenger to the convoy," Lucius said. "This one travels south first, then turns east after the terraces. He tells the escort to keep moving unless they are physically blocked. No stopping for riders. No turning toward any sign that does not become contact."
The rider nodded.
"Tell them to tighten the wagons only at the narrow cuts," Lucius added. "On open ground, spread enough that one strike cannot halt the whole train."
"Yes, tribune."
The patrol leader remounted and disappeared into the dark.
Marcus watched the man go.
"You think the convoy is being shaped toward a stopping place."
"I think Hamilcar's riders are trying to find out whether it can be shaped."
"What if they have already found it?"
Lucius looked toward the high eastern road.
"Then we find out what they have placed there before the convoy reaches it."
A second horn sounded from the eastern watch.
Low.
Not alarm.
Movement observed.
The ridge changed without breaking its evening rhythm. Men assigned to the eastern perimeter rose behind stone and scrub. Water carriers stopped where they were and lowered their jars. The nearest officers moved toward the sound without shouting. The main camp fires remained screened. No standard shifted.
Lucius and Marcus crossed the ridge at a quick walk.
The eastern watch lay behind a low stone wall near the old charcoal pit. From there, the ground fell away through broken terraces toward the road the convoy had taken at dawn. Moonlight had not risen fully, but the western glow from the river settlement and the first stars gave enough light to distinguish movement along the road below.
Three riders stood on the far slope.
They had not come close.
They did not need to.
One pointed toward the eastern road, then another turned north. The third remained still long enough that Lucius could see the pale curve of its horse's neck against the ground.
Cassian's patrol had not returned.
The riders below were either part of the same screen or a second group deliberately placed close enough to be counted.
Marcus lowered his voice. "Do we take them?"
"No."
"They are close."
"They want us leaving the ridge."
The riders had positioned themselves beyond easy reach, where Roman cavalry would need to descend through terraces and cross the road before contact became possible. By then, the Numidians could turn north or south into ground they knew better. A pursuit might gain nothing but hoof prints and dust while the actual observation line farther east remained untouched.
Lucius turned toward the eastern centurion.
"Keep the wall held. Send two scouts south through the terraces. They do not follow these riders. They find where the road becomes narrow enough to stop wagons."
The centurion nodded.
The three riders below waited another moment.
Then they withdrew eastward.
No horn marked their departure.
No Roman horse pursued them.
The eastern road remained open.
That was the danger.
A short time later, Cassian returned.
His patrol entered from the north without using the main road, descending through a fold in the ridge where the camp fires could not silhouette them. Cassian dismounted before reaching Lucius.
"The quarry path has been used," he said.
"By the riders?"
"By riders, light infantry, and something heavier."
Marcus looked toward him.
Cassian crouched and traced a rough line in the dirt with the end of a broken twig.
"Wagon tracks crossed the old quarry road yesterday. Not many. Two, perhaps three. They turned south toward the narrow cuts before the convoy route."
Lucius studied the mark.
"They placed wagons there?"
"Or moved them through."
"Fresh?"
"Fresh enough that the wheels still cut through the dry crust."
Cassian looked east. "There is a low ravine where the two roads meet. One wagon placed badly there could stop everything behind it."
Marcus's expression hardened.
The convoy might not be under direct attack at all. Hamilcar's men could have prepared a blockage along the road, then used cavalry to keep Roman scouts occupied until the wounded wagons reached the narrow point. A stopped Roman convoy would need guards. Those guards might call for help. The road would become a fixed position before Rome knew whether the obstruction was accidental, abandoned, or deliberate.
Lucius looked toward the eastern darkness.
"Take one century," he said to Cassian. "Light equipment. No standards. You move along the southern terraces and reach the ravine from above."
Cassian's gaze sharpened.
"You want the blockage read before the convoy reaches it."
"Yes."
"And if the convoy is already there?"
"Then you hold the high ground and keep the road behind it open."
Marcus looked at Lucius. "That leaves the ridge with less infantry."
"It leaves the ridge with the infantry Hamilcar can see."
The general's eyes shifted toward the bridge and settlement across the western lowland.
The Carthaginians would learn that some Roman movement had gone east eventually. But they would not know whether the detachment represented a response to cavalry, a broader shift toward the convoy route, or merely a new screen intended to protect the springs. The Roman standards still stood above the bridge. The north-bank centuries remained visible enough to keep the ford road dangerous. The southern light troops still occupied ground overlooking the lower terraces.
The ridge would remain a question.
Cassian looked toward the men gathering near the eastern line.
"Who holds the convoy road if the ravine is already closed?"
"Varro takes the east-bank ridge with one century. He does not go down unless Cassian signals that the convoy has been stopped."
Cassian gave a brief nod.
"And the riders?"
"They can watch us move," Lucius said. "They cannot stop us from seeing what they prepared."
The first men of Cassian's detachment began gathering beneath the eastern side of the camp.
They carried shields, swords, javelins, rope, and water. No wagons followed. No standard bearer took position. The movement was too small to look like a marching force from far away, but too deliberate to be a casual water escort.
Varro arrived as the first files formed.
He had cleaned the mud from his armor but not yet slept. The strain of the morning remained in the way he carried his shoulders, though his voice stayed level.
"East road?" he asked.
"Ravine beyond it," Lucius said. "Cavalry screen, possible wagon obstruction, perhaps infantry watching the narrow cut."
Varro looked toward the dark terraces.
"And the ridge?"
"You hold the higher route. Keep the convoy road visible from above. Do not descend unless the road is blocked or Cassian is engaged."
Varro nodded.
Corvus stood behind him with the men selected for the east-bank ridge section. His cheek and forearm had been cleaned. The new shield bore fresh marks from the wall fight, but the grip remained firm beneath his hand.
Lucius looked at him.
"You stay with Varro."
"Yes, tribune."
"The road is not a pasture. Do not expect the ground to give you room."
"I will not."
Lucius turned to Cassian.
"You have until the moon rises high enough to show every rider on the terraces. After that, you return or send word. No staying east merely because the road becomes interesting."
Cassian adjusted the strap of his shield.
"Interesting is a poor reason to die."
"It is a common one."
Cassian gave him a glance that held no amusement, then moved toward the detachment.
The men left the ridge in silence.
Their path did not follow the road toward the ravine. It turned south through the old terraces, passing beneath olive trees and broken walls where the night concealed them from riders watching the obvious route. The ground would slow them. That was acceptable. They did not need to reach the narrow cut first.
They needed to reach it from a direction Hamilcar had not prepared to close.
Lucius watched the last shields disappear beneath the terraces.
Then he turned west.
Across the watercourse, Carthaginian fires shifted again near the western rise. The settlement remained occupied. The bridge guard remained in place. The northern pasture held new infantry. From where he stood, no movement suggested that Hamilcar knew Roman soldiers were already moving toward the road behind the ridge.
But the enemy commander had learned quickly before.
He would learn again.
The road east of the Roman position had become a new field before either army had drawn a line upon it.
And somewhere beyond the terraces, near the narrow ravine where wounded wagons could not turn easily and cavalry could watch from higher ground, Hamilcar's riders were waiting to see whether Rome would arrive as a convoy, a rescue, or another answer they could make expensive.
Cassian's detachment left the ridge beneath the cover of the southern terraces, moving first through the abandoned olive plots where low walls broke the slope into narrow levels. The men traveled without standards and without the noise of a marching column. Their shields were wrapped where loose fittings might strike stone. Water skins were tied close against their sides. Javelins remained in hand rather than slung, because the ground gave no warning before a wall, a tree line, or a fold in the earth became close enough to hide an enemy.
Cassian kept the first files spread far enough apart that no single javelin throw or sudden descent by cavalry could catch too many men in one place. At the same time, he refused to let the line stretch into isolated groups. The terraces were narrow, but not simple. Several old walls had collapsed into loose stone. Olive roots pushed through the soil where rain had cut shallow channels. In places, the plots ended abruptly against a drop where the ground fell toward the eastern road.
The main road remained below them.
They could see it only in fragments through the trees and broken walls, pale beneath the growing moonlight. No wagons moved along it now. No Roman convoy lanterns marked the eastern distance. That did not mean the wagons were safe. It meant the road had become quiet enough for every dark shape beside it to matter.
Cassian paused at the edge of a low wall and raised his hand.
The men behind him stopped.
Below, two riders moved along the road.
They were not close enough for Cassian to see their faces, but their posture revealed the purpose. One rode ahead at a slow walk, turning his head toward every bend and side path. The other remained farther back near a cluster of broken stone, watching the road behind him rather than the ground ahead.
Scouts.
Not a screen placed to stop a Roman force.
A screen placed to tell someone when the Roman force arrived.
Cassian crouched behind the wall beside the centurion commanding the leading section.
"They are looking east," the officer whispered.
"They expect the convoy."
"They may not expect us."
"No," Cassian said. "That is why we do not become visible."
The riders continued eastward, moving toward the narrow ravine beyond the next rise.
Cassian waited until the road was empty again before bringing his men forward.
They crossed the lower terraces without descending fully onto the road, using the broken plots and lines of scrub to keep the slope between themselves and the open ground. The route was slower than the direct approach. It also allowed them to see the ravine from above before anyone inside it could see the Roman shields approaching.
By the time they reached the final terrace, the moon had risen high enough to silver the pale stones along the eastern slope.
The ravine lay below them.
It was narrower than Cassian had imagined from the scout reports. The road entered from the west through a shallow dip, then passed between two steep shoulders of earth and rock before bending southeast toward the convoy route. Old quarry work had cut into one side of the ravine years earlier, leaving a rough wall of exposed stone above the road. On the opposite side, the slope climbed more gradually but was thick with scrub, broken terraces, and enough shallow folds to hide men lying still.
At the narrowest point, a wagon stood across the road.
Its wheels had been removed.
The wooden body rested at an angle between the rock wall and the opposite bank, leaving only a narrow gap beside it where a single horse might pass with difficulty. Several crates and bundles lay scattered around the wagon as though it had broken down during movement and been abandoned in haste.
Cassian looked at it for several breaths.
Nothing about it was convincing.
The wagon had been placed too cleanly. Its axle did not appear cracked. The cargo around it was too evenly spread, forming obstacles rather than the untidy spill of a real accident. The road ahead remained visible for only a short distance beyond the obstruction before it curved behind the southern shoulder.
A wounded convoy reaching that point would stop.
The lead wagons would attempt to turn or push through the narrow gap. The rear wagons would stack behind them. Guards would form on the road because the terrain offered little room elsewhere.
Then cavalry would appear along the slopes.
Or light infantry would rise from the scrub.
Or both.
Cassian motioned for the leading officers to gather beneath the wall.
"No one goes down," he said quietly. "We count first."
The centurion beside him studied the higher bank. "There are places for men above the wagon."
"There are places for men everywhere."
"Can we clear the upper slope?"
"We can clear one slope and tell them exactly where we are."
Cassian looked toward the opposite side of the ravine.
The trap had been prepared for wagons moving east. Its focus lay on the road and the narrow space around the obstruction. The higher terraces from which Cassian had approached were less useful to men expecting a convoy because they did not provide an easy descent into the road without exposing themselves to the same ground they meant to control.
The Roman detachment had reached the ravine from the wrong direction.
That did not make the trap harmless.
It made it incomplete.
Cassian pointed toward the exposed quarry wall.
"Second section holds the wall above the road. Third section moves south through the upper scrub and finds the ravine exit. No contact unless they find men waiting close enough to stop them."
The officers nodded.
"First section remains here with me. We watch the wagon and the northern slope. No thrown javelins. No signals unless there is contact."
The men moved.
The second section slipped down toward the quarry wall, using the broken stone as cover. They did not descend into the ravine itself. Instead, they took the upper ledge where they could see over the wagon and into the narrow road below. The third section disappeared southward through the scrub, moving carefully around the shoulder of the ravine toward the road's eastern exit.
Cassian remained above the northern side with the first section.
For several moments, nothing moved.
Then one of the soldiers beside him touched his arm and pointed toward the opposite bank.
A strip of cloth had shifted beneath the scrub.
Not from wind.
The night air remained still.
Cassian watched the place where the cloth had appeared.
A helmet rose slowly above the grass, then lowered again.
One man.
Perhaps more behind him.
The Carthaginian sentries did not know the Romans had reached the upper terraces. They were watching the road. Their bodies faced eastward toward the direction from which the convoy would approach. Their attention rested on the narrow cut and the wagon barrier below.
Cassian looked down at the Roman section holding the quarry wall.
The centurion there had seen the same movement. He did not signal. He only lowered his head and shifted two men farther along the stone.
Cassian understood.
The trap could be taken apart without announcing its discovery.
A faint scrape came from the southern scrub.
Cassian's hand went toward his sword.
Then the third-section scout appeared at the edge of the terrace, moving low through the brush. He reached Cassian and crouched beside him.
"The eastern exit is watched," the scout whispered. "Four men near the road, perhaps more behind the lower wall. There is another wagon farther south, but it is not blocking the road. It carries supplies or spare shields. Two horses tethered nearby."
"Any cavalry?"
"Not at the exit. We heard horses farther east. More than two."
Cassian nodded.
The ravine did not hold a full force. It held a fixed ambush: watchers on the slopes, infantry close enough to lock the road, horses and riders farther east where they could arrive after the convoy stopped.
That made the enemy dangerous.
It also made them vulnerable to being cut off from the very road they had chosen.
Cassian looked toward the wagon barrier.
"If the convoy reaches this, they close from both ends," he said.
The scout nodded.
"They do not expect infantry from above."
"No."
Cassian considered the time.
The moon had risen high enough that any sudden movement would reveal itself across the terraces. Lucius had ordered him to return or send word before the moonlight made every rider visible. He had found the obstruction. He had found the ambush positions. The next task was not to destroy the trap.
It was to ensure the convoy did not enter it.
A runner had to reach the eastern road before the wounded wagons did.
Cassian turned to the leading centurion.
"Choose two men. They go east through the southern scrub, not the road. They find the convoy and tell it to halt at the second spring. No movement through the ravine until the road is cleared."
The centurion nodded and selected the men immediately.
"Tell the convoy commander the road is blocked deliberately," Cassian added. "Tell him no wagon turns back on the narrow road. He gathers his escort on open ground and waits."
The two runners moved off into the dark.
Cassian watched until the scrub swallowed them.
Then he looked back toward the ravine.
The enemy had built the trap to stop a convoy. If the convoy stopped short of it, the wagon barrier became a burden to the men holding the road. The ambush party would have to remain in position, uncertain whether its watchers had missed the Roman movement or whether the convoy had simply delayed. The longer they waited, the more likely a messenger rode east or west to ask why the road had not filled with wounded wagons.
Cassian could leave the ambush intact and let it waste Hamilcar's men.
But the wagon also blocked the road Rome would need if it chose to move the convoy safely west again.
The barrier had to be removed eventually.
The question was whether it should be removed now, while the Carthaginians still believed it unseen.
A low whistle came from the quarry wall.
Not an alarm.
A signal Cassian had ordered only if a clear count became possible.
He moved down along the terrace toward the centurion holding the stone ledge.
The officer waited behind a broken lip of rock, watching the wagon below.
"Four visible on the north bank," he whispered. "Three near the southern exit. At least two behind the wagon."
"Only two?"
"Only two I can see."
Cassian looked at the road.
The wagon blocked most of the view. The men behind it could be crouched beside the crates or lying beneath the broken canvas. The opposite slope held more than the single helmet Cassian had seen. The road beyond the eastern bend held horses and likely mounted men ready to ride once the trap closed.
There could be fifteen men.
There could be thirty.
A direct attack might clear the ravine, but it would reveal the Roman detachment before the riders farther east could be counted. A quiet withdrawal would preserve the discovery but leave the road closed and the enemy free to reuse the position after the convoy changed course.
Cassian needed the trap to tell him more.
He waited.
The silence stretched.
Then, from beyond the eastern exit, a horse whinnied.
A voice answered in Punic.
Another voice replied from the upper south bank.
The tone carried no alarm. It carried impatience.
The ambush had been waiting long enough to expect the convoy already.
Cassian heard an officer say something too softly to understand, followed by the faint scrape of a man shifting position behind the wagon.
The Carthaginians were preparing to send a messenger.
That was the moment.
Cassian turned toward the centurion.
"Take the quarry wall," he whispered. "Do not descend until the messenger leaves the eastern exit. When he does, block him from the south. First section closes the north bank. We take the men above the road before they can signal the riders."
The centurion nodded.
"And the wagon?"
"Leave it."
The barrier remained useful if it trapped the ambush within its own narrow ground. The Romans did not need to clear the road before dawn. They needed to remove the men who could turn it into a killing place.
Cassian returned to the northern terrace.
The first section shifted behind the low wall, spreading toward the upper slope where the Carthaginian helmet had appeared. Roman shields remained low. Swords stayed sheathed until close contact became unavoidable. The men moved with the care required for a strike that depended on surprise more than force.
Below them, a Carthaginian officer finally rose from behind the wagon.
He spoke toward the eastern exit.
A rider answered from beyond the bend.
The officer gestured sharply.
A mounted messenger appeared at the far edge of the ravine.
He rode toward the blocked wagon, not through the narrow road, but along the lower southern side where a horse could pass only with care. He had no reason to expect Roman infantry above him. His attention remained on the obstruction and the men waiting beside it.
The quarry-wall centurion gave the signal.
Roman shields came up along the stone ledge.
The messenger saw them at the same instant.
He pulled his horse hard to the right, trying to turn back toward the eastern exit.
The second Roman section descended from the quarry wall in a controlled rush, not at the horse itself but at the narrow path behind it. Javelins struck the earth and stones ahead of the rider, blocking the simplest turn. The horse reared. The messenger fought the reins, shouted something in Punic, and tried to force the animal through the scrub.
Cassian's first section came down from the northern terrace.
The Carthaginian sentries above the road rose in confusion. One reached for a horn. A Roman soldier struck him from behind with the edge of a shield before he could bring it to his lips. Another sentry threw a javelin downhill without aiming and hit the wagon side. The sound cracked through the ravine.
The trap woke.
Men rose from behind the wagon and crates. Light infantry scrambled up the opposite slope. A horn sounded once from the southern exit before the Roman section there cut off the path.
Cassian reached the northern bank as the first close fighting began.
The ground was too narrow for a broad line. That favored the men who arrived first with purpose. Roman soldiers pressed down from the terraces in short groups, shields angled toward the road while others held the upper ground to prevent the Carthaginians from escaping into the scrub.
The enemy tried to close around the wagon.
That was what they had prepared to do when wounded Roman wagons entered the cut.
Now the road filled with their own men instead.
A Carthaginian soldier lunged from behind a crate with a short spear. Cassian caught the shaft against his shield, twisted it aside, and drove the shield edge into the man's shoulder hard enough to send him backward into the wagon wheel. Another soldier came from the southern side, sword raised. Cassian stepped into him before the blade could gather force, struck with the pommel, and pushed him down against the road's loose stone.
The fight remained close and broken.
No one could see more than a few paces beyond the wagon. The Roman sections had to trust their officers' positions and the pressure of friendly shields beside them. A man who moved too far forward might step into the southern exit where the mounted riders could still arrive. A man who pulled back too quickly might open the upper slope for the ambush party to escape.
Cassian saw the messenger's horse bolt through the northern scrub without its rider.
The rider himself had fallen near the wall, pinned beneath the animal's first turn and then struck by a Roman javelin before he could rise.
The eastern exit remained contested.
The third Roman section held it against the first Carthaginian response, but the horses beyond the bend had heard the horn. Hooves struck the road. Riders were coming.
"Wall section!" Cassian called. "Hold the exit. Do not chase the road."
The centurion nearest the southern bend acknowledged.
The Carthaginian riders appeared moments later.
They could not charge into the ravine. The wagon blocked the road. Their own infantry had filled the narrow ground around it. The first two riders halted above the eastern bend, trying to understand why Roman shields stood where the ambush should have been.
Cassian saw them through the gap.
They saw him.
One threw a javelin.
It struck the wagon's side near Cassian's shoulder and buried itself in the wood.
The riders withdrew a few paces, then began moving along the upper slope, searching for a way around the ravine.
Cassian looked toward the northern terrace.
The ground above was held.
The southern slope remained partly contested, but the Roman section there had pushed the Carthaginian infantry back toward the road exit. The ambush had not been destroyed entirely. Several men still held the scrub on the far side. Yet its shape had broken. The wagon barrier no longer trapped a Roman convoy. It trapped the men who had depended upon the road remaining empty until the right victims arrived.
A Roman runner reached Cassian from the southern scrub, breathless but unhurt.
"The convoy received the message," he said. "It has halted at the second spring. The escort is forming on open ground."
Cassian nodded once.
"Any riders near them?"
"Seen on the northern ridge. None close."
The convoy was safe for the moment.
That changed the value of the ravine.
Cassian did not need to hold it until dawn. He needed to leave it in a condition Hamilcar could not reuse easily, then return before the mounted force above the bend gathered enough men to close the terraces around him.
He looked at the wagon.
"Strip the axle pins," he ordered. "Take the wheel fittings. Burn the canvas and crates that can burn. Leave the body in the road."
The centurion beside him glanced toward the eastern riders. "Here?"
"Here."
The fire would not remove the obstruction. It would make the obstruction worse for anyone trying to move the road before daylight. The wagon would remain across the narrow cut, but now the Carthaginians would have to clear their own burned barrier under Roman observation or abandon the route for another passage.
The first flames took quickly.
Dry canvas caught along the wagon side. Rope smoldered, then burned. Crates splintered beneath Roman axes before being pushed against the wood. Smoke rose through the ravine, turning the moonlight orange and black between the banks.
The Carthaginian riders above the exit shouted to one another.
More hoofbeats approached from the east.
Cassian saw the danger.
"Withdraw by the quarry wall," he said. "First section first. Third section covers the exit until the others are above the terraces."
The Roman movement began at once.
The men did not flee. They backed up through the ground they had taken, leaving the burning wagon between themselves and the road. The quarry wall gave them cover from the eastern bend. The northern terrace gave them height against any riders trying to climb after them. The southern section held longest, shields angled toward the road as the first mounted men began dismounting beyond the bend.
Cassian remained with the rear section until the final shields reached the upper slope.
Below, the ravine filled with smoke, shouting, and the crack of burning wood.
The Carthaginians had not lost a major force.
They had lost the shape of their trap.
More important, Hamilcar would learn before dawn that the road behind the Roman ridge could not be made dangerous merely by waiting for a convoy to arrive where it was expected.
Cassian led his men back through the terraces.
They moved quickly now, but not blindly. Riders remained above the eastern road. The scrub and walls that had concealed their approach could also conceal pursuit. Roman scouts stayed behind the main detachment, watching the ravine and the southern slopes for movement. Every few moments, the glow of the burning wagon appeared through the trees behind them, a low orange pulse against the dark ground.
By the time they reached the last rise below the Roman ridge, no pursuit had come close enough to force contact.
The riders had watched.
They had not followed into the terraces.
That, too, mattered.
Cassian climbed the final slope toward Lucius's eastern watch shortly before the moon reached its highest point.
The centurion on duty saw the returning shields and sent a runner toward the command awning. Lucius arrived as Cassian's men entered the outer line, smoke clinging to their armor and cloaks.
Cassian stopped before him.
"The road was blocked," he said. "One wagon across the ravine, sentries above it, light infantry at both exits, riders farther east."
"And the convoy?"
"Stopped before the cut. It is secure at the second spring."
Lucius looked past him toward the faint glow beyond the terraces.
"The fire?"
"The wagon will still block the road at dawn. It will cost them time to clear. The ambush cannot be rebuilt quickly."
Cassian's expression remained hard.
"They knew the convoy route. They had prepared the ravine for it."
"Yes," Lucius said.
"And now they know we found it."
"Yes."
The two men stood in silence for a moment while the returning detachment moved through the eastern lanes, wounded men separated from those still fit for watch, water passed hand to hand, and officers counted shields before allowing anyone to settle.
The road behind Rome had not been taken.
But it had become visible.
Across the western lowland, Hamilcar's river position still held its lamps near the bridge and storehouses. Beyond the eastern terraces, the ravine burned where his riders had waited for Roman wagons.
The field had stretched in both directions.
And before morning, each commander would have to decide whether the road behind the enemy was worth more than the ground before him.
Lucius did not return immediately to the command awning after Cassian's report. He remained near the eastern watch while the returning detachment passed through the outer line in small groups, each section counted before it was released toward water, treatment, or rest. The men carried the smell of smoke with them. It clung to cloaks, hair, shield straps, and the folds of their tunics. Some had blood on their armor, though most of it belonged to no wound severe enough to demand more than cleaning and bandaging. The harder evidence of the ravine lay behind them: torn sleeves, bruised hands, cracked shield rims, and the exhausted stiffness of men who had climbed, fought in narrow ground, burned a roadblock, and withdrawn before mounted pursuit could find the terraces.
The eastern centurion approached Cassian while an assistant checked the cut along his forearm.
"How many enemy?" the centurion asked.
Cassian looked toward the faint glow beyond the dark slope. "Enough to stop a convoy. Not enough to hold the ravine once they were forced to fight for it."
"Cavalry?"
"Waiting east of the road. More riders arrived after the horn."
The centurion looked toward Lucius. "They may come after us before dawn."
"They may," Lucius said.
The answer did not settle anything.
The burning wagon gave the Carthaginians a reason to return to the ravine. The destroyed ambush gave them a reason to believe Roman infantry had moved farther east than expected. The halted convoy at the second spring gave them a target if their riders could reach it before the Roman escort resumed movement. Every possibility ran along the same road.
Cassian finished binding his forearm himself, knotting the cloth one-handed with practiced impatience.
"The convoy cannot stay at the second spring until sunrise," he said. "The ground there is open enough for riders to count every wagon."
"No," Lucius said.
"If it moves east, it may find another obstruction."
"Yes."
"If it moves west, it returns toward us with wounded and wagons on a road Hamilcar now knows we are willing to protect."
"Yes."
Cassian looked at him. "You have a third answer."
Lucius watched the eastern road disappear between the terraces.
"The convoy does not move on the road."
Cassian's expression sharpened.
"The ground south of the second spring?" he asked.
"Not the main road. The old cultivation paths. Naso's scouts saw mule tracks there earlier."
"They are slower."
"They are wider in places. More difficult for wagons, but less useful for cavalry."
"And the wounded?"
"They move by handcart where the path narrows. The escort breaks the train into smaller groups. No single obstruction can stop the entire convoy."
Cassian considered the cost.
The Roman wounded convoy had been organized for the road because roads allowed speed, water access, and wagon movement. Leaving that road meant reduced pace, harder labor, and a longer journey through terraces where every turn might conceal more scouts. But the ravine had proved the danger of allowing a single line of wagons to become a single question.
"The convoy commander will dislike it," Cassian said.
"He may dislike being trapped more."
"Possibly."
Lucius turned toward the eastern centurion.
"Send a runner to the second spring. The convoy divides before dawn. The wounded who cannot be moved from wagons remain with the larger escort and take the southern cultivation track. The lighter carts and walking wounded follow the northern terrace path with smaller guards. No fires. No road lanterns. Each group stops only if the path becomes physically impassable."
The centurion nodded. "And the road itself?"
"Leave two scouts at the ravine. Hidden. They watch what the Carthaginians do with the burned wagon and whether infantry arrives from the west."
"Yes, tribune."
The orders passed into the dark.
Cassian watched the runner go, then looked west toward the lowland.
"Hamilcar will learn the convoy did not come through the ravine."
"He may."
"He will know we found another path."
"He will know we refused to keep giving him the same road."
The centurion said nothing after that.
Below the ridge, the watercourse remained a dark line separating Roman high ground from Carthaginian fires. The bridge guard had relit several lamps near the western stone wall. More light appeared along the northern ford road, where infantry had returned after the day's engagement. The settlement itself had not quieted. Men continued moving between storehouses, animal pens, and the western rise where labor crews had been building earthworks. Hamilcar had not treated the burning ravine as enough reason to change his visible posture around the river.
That restraint could mean confidence.
It could mean he had not yet received the report.
It could mean the river position was no longer the only place he expected the next morning to matter.
Lucius walked back toward the command awning with Cassian beside him.
Marcus waited there, joined by Varro and Naso. The scout leader had returned from the southern water routes after receiving the first word of the ravine's discovery, and dust still darkened the knees of his tunic where he had moved through the lower terraces.
"The roadblock was real?" Marcus asked.
"Deliberate," Cassian said. "A wagon with the wheels removed. Sentries above the cut. Light infantry at both exits. Riders waiting east."
Naso's expression remained unreadable.
"Did they use the south bank?" he asked.
"Partly. More men above the northern side."
"Then they expected the convoy to halt facing east," Naso said. "The riders would have come from behind the southern shoulder after the first wagons stopped."
Cassian looked toward him. "That is what we found."
Naso moved closer to the map and placed a finger against the road beyond the second spring.
"There is another route farther south than the one you ordered for the convoy," he said. "It is poor for carts, but a man can walk it with a mule. It crosses behind the old terraces and comes out near the abandoned charcoal pits west of the first valley."
Lucius looked at him. "Can the most wounded use it?"
"No. Not without carrying them part of the way."
"The walking wounded?"
"Yes."
"The supplies?"
"Some."
Marcus studied the route. "Why mention it now?"
"Because the Carthaginians may know the cultivation path too. They prepared the ravine with wagon movement in mind, but no one places an ambush on a road without checking the ground around it. If the convoy divides, they may try to shape both groups toward the paths they prefer."
Cassian folded his arms. "So we divide the convoy and give them two targets."
"No," Naso said. "We divide it and give them no target large enough to make the road worth closing."
The scout leader looked toward Lucius.
"A wagon train gives cavalry a reason to wait. A line of wounded men with pack mules gives them less. The riders can harass, count, and signal. They cannot trap a road that is no longer carrying the thing they prepared to trap."
Lucius considered the ground.
The convoy could not vanish entirely. The dead, the severely wounded, and the stores still needed movement. But Naso's point was sound. A divided train required more escort coordination and more labor. It also deprived Hamilcar of the one thing his ambush had been designed to seize: time created by a blocked road and wagons unable to turn.
"Send another messenger," Lucius said. "The walking wounded and light stores go south with the mule route. The largest wagons remain on the cultivation track. No more than four wagons in a group. The most injured travel with the first group. The others leave after an interval."
Marcus looked toward the eastern dark. "You are making the convoy slower."
"I am making it harder to stop."
Naso gave a slight nod.
Cassian said, "And the ridge?"
Lucius looked toward the western bridge.
"The ridge remains where Hamilcar can see it."
The answer mattered because it kept the Roman position from appearing weakened by the eastern response. The main standards would remain above the central crossing. The reserve centuries would hold the northern high ground. Varro's men would rest, repair, and remain ready near the eastern trees. The southern light troops would continue appearing capable of movement toward the terraces and ravine.
Rome would protect its road without visibly abandoning the water.
That was the balance Lucius intended Hamilcar to read.
Across the river, Hamilcar received the report from the ravine shortly before midnight.
The messenger came from the eastern side of the settlement on a horse lathered along the neck and flanks. He dismounted near the western rise before reaching the command shelter, leaving the animal with a handler and moving on foot through the ordered darkness of the Carthaginian camp.
Maharbal met him first.
"What happened?"
"Romans came from the terraces," the rider said. "They reached the upper ground before the convoy arrived. They struck the sentries and burned the blocking wagon."
"Did the convoy enter the ravine?"
"No."
"Did they take the road?"
"They withdrew into the terraces before more riders could close on them."
Maharbal's gaze shifted toward Hamilcar.
The Carthaginian commander stood near the map table beneath a low awning, one hand resting beside the river markers and the roads leading east from the Roman ridge. Several lamps burned near the table, but their light remained screened from the slope beyond camp.
"They found the ambush," Maharbal said.
"Yes."
"They will change the convoy route."
"Yes."
The messenger waited, uncertain whether more questions would follow.
Hamilcar looked at him. "How many Romans?"
"Two sections at first. Perhaps more above the terraces. We could not count once the wagon burned."
"Any standards?"
"No."
"Any cavalry?"
"None seen."
Hamilcar nodded once.
The detachment had been small enough to move silently and approach from the wrong side of the ravine. Lucius had not sent a full force toward the convoy. He had sent men to read the road before committing to its meaning. The same habit had appeared at the river, the depression, the cart track, and the divided roads.
Maharbal leaned over the map.
"The convoy will move south," he said. "Or north."
"Perhaps both."
"They cannot carry the worst wounded through the terraces."
"No."
"Then the larger wagons remain somewhere we can find."
Hamilcar looked east.
The temptation was obvious. Send cavalry farther along the road. Find the convoy. Pressure it until the guards reveal themselves. Force the wounded wagons back toward a road the Carthaginians could prepare again. Rome had been careful, but careful movement took time, and wounded men moved slowly no matter how a commander divided them.
Yet the road behind the ridge had already drawn Roman infantry eastward. Cassian's detachment had appeared where the ambush had expected only wagons. More pressure on the convoy might pull still more Roman strength away from the watercourse. It might also lead cavalry beyond support into terraces where infantry could wait above every wall.
Hamilcar had learned not to assume that a road remained empty merely because its first movement belonged to the enemy.
"Do not ride after the convoy blindly," he said.
Maharbal looked toward him.
"Keep riders east of the second spring. Watch the roads, the terraces, and the cultivation tracks. Let them see enough movement to know we remain near them. But no attack on wagons unless they stop or separate from their escort."
"You want them worried."
"I want them carrying their worry farther east."
Maharbal understood.
The cavalry did not need a victory against the convoy. It needed to stretch Roman attention across more ground, make every guard escort feel watched, and force Lucius to decide how long his main position could remain beside the river while his rear road became a place of constant warning.
"And the river?" Maharbal asked.
Hamilcar looked toward the northern ford.
"The bridge remains held. The pasture stays watched. Move the labor crews farther west before dawn. The rise work becomes visible only after the stores have shifted."
Maharbal's expression sharpened.
"You are moving the stores again."
"Some of them."
"Because Scipio will not take the bridge."
"He will take something eventually."
The Carthaginian commander did not intend to allow the settlement's supplies to remain piled beneath Roman observation long enough for Lucius to decide that a dawn assault might be worth the cost. Hamilcar could move what mattered most farther west while leaving enough stores and wagons visible to keep the settlement useful as a target.
The river would remain a position.
It would not remain the whole position.
Before dawn, both armies continued working.
The Roman convoy began dividing at the second spring. The largest wagon group moved south first beneath a reinforced escort, leaving the main road and entering the cultivation paths one careful bend at a time. The wounded who could walk followed with mules carrying water, blankets, and spare arms. A smaller wagon group waited under guard until the first movement had disappeared behind the terraces.
No torchlight marked the route.
Men moved by moonlight, memory, and the pale surfaces of stone walls.
Roman scouts ranged ahead of each group, not searching for every rider but looking for the signs that mattered: hoof marks where no animals should have passed, disturbed scrub above a narrow path, tracks crossing from one terrace level to another, stones moved recently enough that the pale underside still showed against the earth.
The convoy did not move quickly.
It moved without giving the road a single body to stop.
At the ridge, Lucius slept only briefly.
Cassian found him awake near the map table before the moon had begun lowering westward. The centurion had washed smoke from his face and replaced the torn strip of cloth around his forearm, but fatigue remained in his eyes.
"The first convoy group is moving," he said.
"Any riders?"
"Scouts saw movement north of the road. No contact."
"Good."
Cassian looked toward the western lights. "The Carthaginian camp has changed."
Lucius followed his gaze.
Several lamps near the northern storehouses had gone dark. More movement appeared farther west along the rise, but the distance made it difficult to tell whether wagons were leaving or merely being repositioned. Hamilcar might be shifting stores. He might be preparing more earthworks. He might be creating visible movement to occupy Roman observation while the real work happened somewhere else.
Either way, the settlement was not settling.
"No rest," Cassian said.
"Not tonight."
"Not for either side."
Lucius studied the river.
The Carthaginians held the water. The Romans held the ridge. Cavalry watched the roads behind Rome. Roman scouts watched the routes feeding Hamilcar's settlement. Every piece of ground had become useful enough that neither commander could leave it alone.
The next decision could not be another attempt to seize a crossing merely because the enemy still guarded it.
The next decision had to make one side choose between holding the water, protecting the roads, or preserving the stores moving west.
Lucius placed a marker beyond the settlement's western rise.
Cassian watched him.
"The labor crews," the centurion said.
"Yes."
"You think the stores are moving."
"I think Hamilcar wants us to see enough work at the rise to believe the stores remain where they were."
"And if they do?"
"Then the rise matters."
Cassian leaned closer to the map.
"How do we reach it?"
"Not from the bridge."
The answer came without hesitation.
The bridge had become a known measure. Hamilcar expected Rome to pressure it if the settlement stores appeared vulnerable. The northern ford remained watched. The southern terraces remained guarded. The western rise could not be approached directly without crossing ground Hamilcar had spent days learning to prepare.
But the ridge north of the Roman camp continued beyond the northern pasture. The east-bank centuries had already mapped part of that higher ground. A route might exist along the northern shoulder where infantry could move above the ford road and descend west of the visible settlement without using the bridge at all.
It would be difficult.
It would also ask a new question.
"Send scouts north before dawn," Lucius said. "Third-century men who know the east-bank rise. They find whether the northern ridge runs behind the ford and toward the western works."
Cassian looked toward him. "A route around the water."
"A route around the crossings."
The centurion gave a slow nod.
"And if there is no route?"
"Then we know Hamilcar chose the river ground well."
"And if there is?"
Lucius looked toward the western rise, where faint movement continued behind the dark line of tents.
"Then tomorrow, we find out whether he holds the water because it protects the settlement—or because it protects what is leaving it."
The first pale gray of morning had not yet reached the eastern ridge when the scouts departed northward.
The convoy continued its slow movement away from the ravine.
The Carthaginian riders remained somewhere beyond the terraces, watching roads that no longer carried a single easy target.
And across the western lowland, beneath the guarded bridge and the lights of the settlement, Hamilcar shifted his stores toward ground he hoped Rome had not yet learned to reach.
