Sedan Defense Line

On April 16, 1940, a train stopped in Sedan.

The train slowly came to a stop, puffing out white steam.

Lorraine picked up his suitcase and, along with the other passengers, disembarked. The platform was much smaller than Gare du Nord, a brick structure with rusted iron frames on the roof. The air smelled different—a mixture of forest, earth, and smelting.

Several soldiers patrolled the platform, rifles slung across their shoulders, their movements languid. A sergeant, a cigarette dangling from his lips, leaned against a pillar and dozed off.

Lorraine presented his credentials and transfer order.

The sergeant glanced at it and raised his chin: "The division headquarters is in the old castle in the east of the city. A truck is leaving in half an hour; you can hitch a ride."

"Thanks."

Loren walked to the edge of the platform and looked out over the small town. Sedan sits at a bend in the Meuse River, with the rolling Ardennes on the opposite bank.

The April sun shone on the slate rooftops, the church bell tower stood in the city center, and the outline of the fortress's concrete fortifications could be seen in the distance.

It looked calm, solid, and even somewhat drowsy.

A scene appeared before Loran's eyes.

The German armored vanguard will break out of the forest to the east, cross the Meuse River, and tear open the first gap in the French defenses.

"Is this your first time in Sedan?"

The voice came from behind.

Lorraine turned around and saw a captain in his thirties, his face tanned dark, his uniform stained with mud but ironed perfectly.

"Yes," Lorraine nodded. "Mark Lorraine, reporting for duty today."

"Jean-Claude Zorro, Operations Staff Officer, 55th Division." The captain extended his hand, shaking it firmly. "Colonel Delattel sent me to pick you up. The truck won't leave for an hour, so I drove here."

They walked outside the station. A military Citroën was parked on the side of the road, its hood covered in dust.

"How's Paris?" Claude asked as he started the car, his tone casual, as if he were chatting.

"I still believe the Maginot Line can stop everything," Lorraine said.

Claude smiled, a brief, bitter smile: "The people here are too. Except we believe in the Meuse River and the Ardennes Forest."

The car drove through the streets of Sedan. The small town was quiet; shops were open as usual, elderly people sat outside cafes, and several children played football in the square.

"How is the situation at the division headquarters?" Loran asked.

Claude glanced at him: "You were recommended by General Bouchard, and you even have a letter of contact from Colonel de Gaulle. So I guess you're not here to ask about the surface situation."

Lorraine did not deny it.

"The situation is bad," Claude said bluntly. "The 55th Division is a second-line infantry division with an average age of thirty-four and equipment left over from 1918."

Our defensive line stretches along the Meuse River, forty kilometers wide. That sounds like a lot, but most of it consists of barbed wire and scattered bunkers.

"What about the Ardennes Forest?"

"Marked 'Impassable'." Claude's tone held a suppressed anger. "The engineers laid some mines and obstacles there, but no permanent fortifications. Command's reasoning was that tanks couldn't get through, so heavy defense wasn't necessary."

The car rounded a bend, and ahead appeared an ancient stone castle, its walls covered in moss. It was the old castle of Sedan Fortress, now used as the headquarters of the 55th Division.

"Colonel Delattel knows the problem," Claude said as he parked the car, "but there's only so much he can do. There are no resources, no reinforcements, no authority. We can only do what we have."

Lorraine nodded, picked up his suitcase, and got out of the car.

In the castle courtyard, several officers were smoking and chatting. When they saw Claude and Lorraine, they stopped talking and cast curious glances at them.

"A new terrain analysis officer," Claude introduced. "He was transferred from the Paris General Staff."

A major raised an eyebrow: "Coming from Paris to a place like this? Made a mistake?"

"I will obey your assignment," Loran said calmly.

The major glanced at him a few times, shrugged, and turned to leave.

Claude said in a low voice, "Don't mind it. People here have a prejudice against officers from Paris; they think they're all bureaucrats sitting in offices."

"I understand."

Lorraine knew this wasn't prejudice; in fact, it was true, most officers were like that.

They entered the main castle building. The stone walls were thick, and the interior was cold and damp. The sounds of typewriters, telephones, and muffled conversations came from the rooms along the corridors.

At the far end of the second floor, Claude knocked on an oak door.

"Come in."

His voice was steady and powerful.

The room was simple, with a large table, a large-scale map of the Sedan region hanging on the wall, bookshelves crammed with documents and books, and an open window offering a view of the courtyard and the Meuse River in the distance.

Colonel Delater stood in front of the map, his back to the door. He was not tall, but he had broad shoulders and a steady posture. Hearing footsteps, he turned around.

This was the first time Loran had met the officer. Delater was about fifty years old, with short, graying hair, a square face, a strong jawline, and gray eyes that looked at people with the focused intensity of someone assessing terrain.

"Lieutenant Mark Lorland, reporting for duty." Lorland saluted.

Henry Delatter returned the greeting with precise movements: "Henry Delatter. Sit."

Lorraine sat down. Claude stood by the door, not leaving.

"General Bouchard wrote me a letter." Delater walked to the table, picked up a letter, and said, "Colonel de Gaulle also sent a letter. It's not common for two people to be contacting the same lieutenant at the same time."

His gaze fell on Lorraine: "What did you do in Paris?"

Lorraine hesitated for a moment. Delatter raised his hand to stop him: "I've seen your transfer file. I've also heard about the reviewing stand incident. The story of six veterans driving their homemade German tanks into the exercise area should be all over Paris."

"That was a demonstration, General," Lorraine said, "to show the threat we face."

"Threat," Delater repeated the word, walking to the map. "What exactly is the threat you've identified?"

Loran stood up and walked to the map. He pointed to the Ardennes Forest region east of Sedan: "Based on my data analysis of the Polish campaign and my assessment of the mobility of the German armored forces, if the Germans choose to break through from the Ardennes Forest, their vanguard could reach the east bank of the Meuse River from the border in as little as forty-eight hours."

He moved his finger, tracing several secondary roads and dried-up riverbeds: "These routes may seem insignificant on the map, but they are wide enough for a single tank to pass through. If the Germans had adopted a multi-pronged, dispersed advance, our forward outposts might have lost contact simultaneously."

Delater listened quietly, his face expressionless.

"Upon reaching the Meuse River," Loran continued, "the German engineers can erect a pontoon bridge within three to five hours. However, based on the current deployment of the 55th Division, our nearest reserve is 20 kilometers north of Sedan. It would take at least six hours for them to receive the alarm, complete their assembly, and reach the riverbank."

He paused for a moment: "This means that if the Germans launch an attack at dawn, they can establish a bridgehead by noon. By the time our reinforcements arrive, they will not be facing troops crossing the river, but rather already fortified defensive positions."

The room was quiet. Only the sounds of drill commands could be heard from afar outside the window.

Delatter stared at the map for a long time. Then he turned to Loran: "What data are you basing your calculations on?"

"German combat records in Poland, publicly available technical parameters, terrain analysis," Loran hesitated for a moment, "and some non-public intelligence assessments."

He didn't mention the cell phone, nor the information from the future. But Delater seemed to understand the unspoken message.

"General Bouchard said you're a 'sophisticated man'," Delatter said, walking back to the table. "Colonel de Gaulle said you 'saw what others didn't want to see.' Now, what do you see here with me?"

Lorraine met his gaze: "I see a defensive line that relies on two assumptions: first, the Meuse River is a natural barrier; second, the Ardennes Forest is impassable. And both of these assumptions could be proven wrong."

Delater was silent for a moment. Then he nodded, as if he had made a decision.

"Captain Claude."

"Yes, Colonel."

"Take Lieutenant Loran to familiarize himself with the defense zone. All areas, including those marked 'impassable.' Show him the complete deployment maps, fortification logs, and communication lines." Delater looked at Loran. "I'll give you three days. In three days, I need a complete vulnerability assessment report for the defense zone. Not theoretical deductions, but specific recommendations based on on-site reconnaissance: where reinforcements are needed, where reinforcements are needed, and where redeployment is required."

"Yes, Colonel," Lorraine said.

"And another thing," Delater added, "your rank is lieutenant, but in my division, rank doesn't mean everything. I need professional judgment, not bureaucratic procedures. If you see a problem, just say it. If you have a suggestion, just offer it. Understand?"

"clear."

"Go."

Stepping out of the office, Claude glanced at Loran, his expression complex: "The Colonel rarely grants such direct authority."

"Because I spoke from the bottom of my heart," Lorraine said.

Claude nodded, asking nothing else, and silently continued doing what he was supposed to do, perhaps not wanting to know what might happen in the future.

For the next three days, Loran followed Claude throughout the 55th Division's defense zone.

They patrolled along the east bank of the Meuse River. The water shimmered a greyish-green in the April sun, flowing gently. Some sections of the bank had been fortified with concrete bunkers, machine gun emplacements, and anti-tank ditches, but more often there were only simple barbed wire and sandbag fortifications.

"This was originally planned to be a permanent fortification," Claude said, pointing to an empty area. "But the cement and steel were all transferred to the Maginot Line. We only received one-tenth of the allocation."

They entered the edge of the Ardennes Forest. The forest was dense, with the branches of oak and beech trees intertwined, and the ground was covered with a thick layer of fallen leaves and moss. The engineers had laid mines and obstacles here, but in limited numbers.

"Can these obstacles stop the tanks?" Loran asked.

The engineering company commander, a veteran in his forties, grinned: "Lieutenant, to be honest? If the Germans really come from a place like this, these things will only slow them down for a few hours at most, but the higher-ups said the tanks can't get through, so this is the only way we can set up."

Lorraine crouched down to examine a felled tree. The trunk was about sixty centimeters in diameter and lay across the road.

"German engineer tanks could clear this obstacle in twenty minutes," he said.

The engineer company commander's smile vanished: "How did you know?"

"The Polish example," Loran stood up. "They had specialized armored engineering vehicles equipped with bulldozer blades and winches. This level of obstacle couldn't stop them."

They continued deeper into the forest. Loran checked their location using the compass and map he carried. In some places, he had Claude stop so he could carefully observe the terrain through his binoculars.

"See that dried-up riverbed?" Loran pointed ahead. "Although it's the dry season, the riverbed has a gentle slope and a hard bottom. Tanks can pass through here."

"It's marked as impassable on the map," Claude said.

"The map was drawn ten years ago. The tanks back then were different from the tanks we have now."

On the afternoon of the third day, they arrived at an observation post at the northernmost edge of the defense zone. The post was built on a small hill, offering a wide view of the Meuse River and the Belgian border on the opposite bank.

The sentry, a young sergeant, saluted upon seeing them: "Sir."

"How is it going?" Claude asked.

"Quiet, sir," the sergeant said. "Nothing's happening in Belgium either. We see their patrols sometimes, but that's about it."

Loran took the binoculars and scanned the horizon on the opposite bank. The forest stretched out, and the hills rose and fell, appearing peaceful and harmless.

But deep within that forest, a large army is likely gathering.

"What about the communication equipment?" Loran asked.

The sergeant pointed to a field telephone and a radio in the outpost: "The telephone line sometimes gets chewed through by animals. The radio signal is bad in the forest."

"If enemy activity is detected, how long will it take to reach division headquarters?"

"If all goes well, ten minutes. If not..." the sergeant shrugged, "we might need to send someone on horseback to deliver the message."

Loran lowered his binoculars. Ten minutes was far too long compared to the speed of an armored assault.

As the sun set, they returned to headquarters. On the way, Claude finally asked the question that had been nagging at him for three days:

"Loran, do you really think the Germans will attack from here?"

Loran looked at the fleeting outline of the forest outside the window: "It's not that I think, it's that I know."

"Know?"

"Based on all the data and analysis," Loran said, avoiding the real answer, "the probability is over 70%, while in the military, a probability of over 30% requires contingency planning."

Claude remained silent for a long time. The car drove across the stone bridge over the Meuse River, the water shimmering with gold in the setting sun.

"Perhaps you're right," Claude finally said, "we can't hold out, can we?"

Loran did not answer directly: "What we can do is to make the cost higher, make the time longer, and give the subsequent defenses a chance to react."

"And what about us?" Claude asked.

Loran fell silent. He knew very well what this arrangement meant; he could very well sacrifice himself here, along with the Sedan defenders, including Colonel Delater.
