Compared to Italy's skirmishes in the Alps, the offensive of its ally Germany was much larger. After defeating the Belgian and British expeditionary forces, the revolving door project has entered a critical moment.

When a million German troops crossed the Belgian-French border from Belgium and attacked France, the French army was terrified. At this time, the No. 17 battle plan for the German attack was no longer mentioned, and the top priority now was to block the German offensive.

As a result, the French army organized several battles one after another, such as the Battle of the Ardennes.

This battle was the result of the French General Staff's belief that since Germany was attacking Belgium, there must be a weak force in the Ardennes in the center, and that the French army would have a great chance of preventing the German army from continuing to advance into the interior of France.

As a result, the French commander-in-chief, Chauffy, ordered Luff's Third Army to march south of the Ardennes, drive the German Fifth Army back to the area from Metz to Theonville, and then encircle it, and at the same time recover the Brière iron ore area. In addition, the French Fourth Army attacked from the north of the Ardennes, and the task was to encircle and annihilate the German Fourth Army.

From a strategic and tactical point of view, the French army did a good job, cutting off the left and right flanks of the German army, then this revolving door will not be able to rotate, and will be broken by the French army.

However, it is a pity that the French army miscalculated the strength of the German army, according to the French estimate, the German army group should have the strength of 6 corps.

The French were right, but there was a delay in their news, because the Germans had 4 reserves to join the two army groups. As a result, the forces that had been prepared to fight the German 6 armies were forced to engage the enemy with 10 armies. This man, weapon, and firepower are all a cut above the boss, and it is a miracle to be able to win.

It was clear that the French army had failed to work a miracle, and after being beaten by the Germans, the French Third Army retreated to Verdun, while the Fourth Army retreated to Sedan and Sterné.

Subsequently, the Anglo-French-Belgian armies were defeated in the Battle of Mons and the Battle of the Sambre River, at which time the three armies on the left flank of the French army had all been defeated, and the two armies on the right flank were still struggling to support in Lorraine. At this time, the right flank of the German army and the five armies in the center were like a sickle, cutting from Belgium to France.

At this time, in order to prevent the British and French troops from gaining a foothold and reorganize the defensive line in order to gain a respite, Kruger's First Army and Bilow's Second Army forced a march all the way to pursue the equally exhausted British and French troops.

Faced with the German army, which was struggling to catch up with them, the British and French troops could only continue to send troops to carry out difficult and dangerous resistance.

In fact, this is more like making the British and French troops constantly lose blood, because in this case, it is not easy to fight after the break, and it is good for the tired and panicked soldier not to point his weapon at you after hearing that you let him be responsible for the break.

In the face of the million-dollar German army attacking from the right flank, Xia Fei, as the commander-in-chief of the French army, of course, is also duty-bound. He then issued General Order No. 2 to draw troops from Lorraine to form a new 7th Army and deploy it on the German right flank.

At the same time, the three armies on the retreating left flank should also try to maintain an intact front as best they can, with rearguard units to make short but fierce counterattacks, to block or at least halt the enemy's advance, and to be ready to relaunch the offensive.

From Xia Fei's order, we can see that the commander-in-chief of the French army still has the idea of attacking.

Of course, this idea is not obvious now, because the gesture of facing the German army has plunged the French capital Paris into a panic.

On the government side, some people are calling Xia Fei an idiot and a fool, and some people are threatening to skin War Secretary Mehmi, but in the end, War Secretary Mehmy stepped down and was replaced by Millerand. At the same time, General Michel, the commander of the defense of Paris, was also relieved of his post and replaced by General Gallieni.

It should be added here that Gallieni took office on the condition that the government promised to transfer three armies to his command. Yes, the new commander of the city defense of Paris is so personal.

Of course, not only that, but the core of the new Seventh Army, led by General Monaurey, with the Lorraine troops, arrived in Paris by train and then marched to the front.

At this time, the right flank of the German army carved a 75-mile wide strip and marched in the direction of Paris, with the First Army led by General Kruger at the forefront. The First Army was the end of the right flank of Schlieffen's plan, the curved tip of the sickle, the farthest march, and at the same time the heaviest task.

Of course, taking into account the heavy tasks and objectives of the First Army, it also has the largest number of troops, equipment, and transport vehicles.

Kruger's First Army had been in hot pursuit of the French Fifth Army. There were also some sporadic battles in the pursuit, and this time the battles ended quickly with a crushing German attack, and the French Fifth Army could be said to have run wildly.

Moltke Jr., who was far behind, when he learned that the distance between the First Army and the Second Army was too large, ordered Kluke to slow down his advance in order to ensure effective cover and coordination with the Second Army. But at this time, General Cluke was eager to fight, and he ordered the German army to speed up its advance, and the French army must not be given a chance to breathe.

When the vanguard of the First Army was only fifteen kilometers from Paris and the Eiffel Tower was already faintly visible, he still ordered his troops to march southeast and continue to pursue the French Fifth Army.

In the face of the menacing German army, there was a panic in France, and the people of Paris rushed to the bank to withdraw their deposits and rushed to the train station, and began a large-scale exodus. The French government and parliament were also moved from Paris to Bordeaux in a panic.

There was a reason for the panic in France, since the German army invaded French territory, the French army also organized several large-scale resistances under the guidance of "Plan No. 17", but the Battle of the Ardennes, the Battle of the Sambre, and the Battle of Mons all ended in the defeat of the French army, and the German offensive seemed invincible at this time. The French people no longer had much hope for the French army.

Regardless of the results of previous battles, the defense of the capital is an imminent matter at the moment of the great enemy. In the midst of the crisis, the French General Staff appointed the veteran Gallière, a veteran general, to be in charge of the defense of Paris. Garielli was ordered to build fortifications around Paris and keep an eye on the latest movements of the German army in search of fighters.

He was overjoyed when he found that the German First Army showed no signs of attacking Paris, but was alone and continued its march southeast of Paris: "They sent the flanks to the door!" “

This judgment was confirmed by the British and French pilots the next day. That is to say, the German army at this time has been carried away by the victory, and the impatience and rashness have caused a big hole in their front.

Garielli recognized this rare opportunity, and he hoped that the French army would seize this advantageous opportunity and deal a fatal blow to the arrogant German army.

Xiafei, who has always been known for his calmness, composure, and fortitude, has also been judging the situation and looking for an opportunity to counterattack, but he did not show much interest in Garianeli's request at this time. The fighters were fleeting, and with the meager strength of the Garielli Sixth Army, it could not stand alone against the well-equipped 200,000 German troops, and more importantly, the attack had to be approved by the General Staff.

Garielli, who was anxiously waiting, called Xia Fei again, once again stating his claim, and asked the General Staff to give the order for a counteroffensive. During the call, Xia Fei also realized the importance of seizing the fighters to organize a counteroffensive, and he agreed that Garyeli could launch an attack on the enemy north of the Marne.

Xia Fei put down the phone and said to the officers present: "Gentlemen, let's fight on the Marne!" “

At this time, a great war was about to break out on the Marne.
