"The Ardennes region is impassable!"

After receiving Roland's prediction that the Alfheim Defense Army would form an armored group to break through in depth from the Ardennes, the Wang Army asserted that he casually threw the deduction prediction report written by Roland into the wastebasket after staying up late for three consecutive days.

Apart from the instinctive element of factional struggle, the Army's response could not be considered vexatious, and if the military generals of any country other than Alfheim read the report, they would have dismissed the "massing of forces to make a breakthrough from the Ardennes" nonsense.

The Ardennes region is a typical area of easy to defend and difficult to attack due to its rugged terrain, dense forests and rivers, which are not suitable for large army gatherings and marches. The defenders don't even need much troops, as long as there are enough sappers and explosives to destroy bridges and key road junctions, any divisional level of troops will be trapped on the road and immobilized. Taking 10,000 steps back, even if there is really a person who does not know how to choose Ardennes as a breakthrough, he must first figure out how to ensure that the logistics supply can keep up with the desperately long marching army, and in the worst case, there will even be various troops scrambling for roads, infantry, cavalry, artillery, and supply wagons are in a mess, blocking the only few roads tightly, and everyone is immobile, waiting for the enemy to destroy him.

If you think it's better to switch to mechanized troops, congratulations, you're going to get a bigger and worse traffic jam hell. Combat vehicles, armored vehicles, self-propelled guns, communications vehicles, and trucks will fill the Ardennes in a convoy all the way to the Remagen Bridge on the Rhine. By the time the troops had rushed out of the forest and arrived on the banks of the Maas River, Charlemagne had already mobilized his troops to strengthen the defenses of the area.

If the pointy-eared people were still sensible, they would never have chosen the Ardennes region as the starting point for the armored forces.

The above argument can never be said to be wrong, and Roland also thinks that this is a very correct analysis, but-

Poverty is not the only thing limiting the imagination.

The lack of sensitivity to technology can likewise limit the space for one's imagination.

If he throws the rifle to the people of the Stone Age, he will only use it as a stick and wave it; if he leaves the atomic bomb on the land of the feudal era, people will only be troubled by this iron lump; he only has in mind the first-class writers of the Battle of Jutland and the Battle of Tsushima, let him write about the cosmic war in the age of the stars and the sea, and he will also write about the two-dimensional plane war that lets a space warship fight the sail age;

Without experiencing the technological progress brought about by industrialization, without seeing the organizational and scheduling capabilities of the modern state, without truly understanding what mechanized warfare is, people who stopped at the pre-industrial era and even drew a map were already high-tech certainly cannot imagine a torrent of steel rushing out of the Ardennes Forest. They even estimated that it would take at least three weeks for the Wehrmacht to reach the banks of the Maas from the Ardennes, and then wait for another week on the riverside to cross the river after heavy artillery had caught up and stockpiled sufficient ammunition.

They think that the defense forces are abacus beads in the hands of others, and let them play with them?

"I'm afraid that over the years, Yalfheim has repeatedly carried out a lot of surveying and sand table deductions, and there are also staff trips of various levels, so that the staff officers can actually feel the environment there and prepare for future combat plans. Alfheim now knows everything about it, the distribution of roads and villages, the effects of weather and seasonal changes, possible situations and coping with them are all taken into account and ready to be activated. ”

"In that case, then we'll be right away—"

"It's too late. ”

Roland interrupted Valrhona, Valrhona's unspoken suggestion had already been rehearsed in his head.

"Even if you blow up all the bridges and piers, and use flash floods to wash away the roads, they can still come over. Let's not forget, the mapping project has long since ended, all roads and bridges have been numbered, prefabricated steel bridge components, engineering equipment to deal with collapse, etc. are ready. What's more, in addition to the armored forces, the opponent also has the main fleet of the air fleet, and after the campaign is launched, it will seize air supremacy, cover the entire battlefield, and provide air transportation and cover if necessary. Not to mention the construction of fortifications in advance, it is too late at all, and it is impossible to stop the integrated air-ground assault if it is barely repaired. ”

"How long will it take for them to break out?"

Valrhona stared at the Maas River on the map, the last natural barrier in front of the Ardennes Forest, and on the north bank of the Maas River was the fortress city of Sedan. Relying on the natural danger of the Maas River, if the heavy troops gathered in Sedang could not stop the strong attack of the armored cluster, at least it could delay its actions and buy time for mobilizing troops to adjust the deployment. However, the royal army thought that since the Ardennes area could not be passed, it was obviously unnecessary for Sedang in the rear to be strictly defended. As a result, the fortifications in the area were far weaker than in the rest of the area, and only a small number of second-line garrisons were deployed. In this state, it is impossible to resist the ironclad front of the defense army.

If Sedan is lost, Charlemagne will not be able to prevent the Wehrmacht armoured cluster from outflanking southward, and Charlemagne's last chance of life will be trapped in the revolving door.

The key to escaping this trap is whether time – the time it takes for the Wehrmacht armoured troops to arrive at the Maas from the Ardennes and cross the river to the city – is enough for Charlemagne to react.

"If you are well prepared, you can reach the banks of the Maas River in about 60~70 hours, and then it only takes one day to break through the Maas River defense line and march towards Sedan. ”

"Completely helpless......"

Valrhona shrugged her shoulders conventionally, and her tone was full of eagerness, showing no sign of giving up.

"Don't sell it, tell us what we're going to do. ”

With a wry smile, Roland pointed his pencil at the map.

"Thionville, Bastogne, Saint-Vitus, as long as you occupy these points, there is a way to slow down the revolving door, or even get stuck!"

"As of 0900 this morning, Army Group B has assembled 5 armored divisions and 3 mechanized infantry divisions, with a total of 1,250 combat vehicles and 41,140 motor vehicles, with a total strength of 135,360 troops, and the main fleet of the Air Force, including the general flagship Emperor, has a total of 17 capital ships and 22 auxiliary ships......

As Brunhill read aloud, a female non-commissioned officer took a small model of a chariot and an aerial battleship from the box and placed it on a giant map table, and soon assembled an army of machines of unprecedented size from the banks of the Rhine to the Ardennes Forest.

Needless to say, Army Group B was by far the most powerful rapid group in the history of warfare in the world, even if it was a head-to-head confrontation with Charlemagne's main forces, let alone a blow to the enemy's weak flank. It's just an easy job.

Only those who are really responsible for participating in the formulation, implementation, and coordination of the entire "Yellow Plan" know what a big gamble this is and how difficult it is to solve.
