In the Alps bordering Italy and France, the Italian army had already received a secret order from the Roman command. After the government issued a declaration of war, they crossed the border without hesitation and attacked the French defense line that they thought was useless. Since the German-French armistice agreement was only valid for Germany and France, and Italy did not participate in the war during the armistice, the French, in addition to expressing indignation and protest, could only rely on a small number of troops deployed in the French-Italy border area to resist. However, the progress of the war surprised people from all countries living in this era. The Italian army, who was raising energy, was actually severely repaired by the weak rooster of the French border defense forces with severe shortages.

After a few days, the Italian army entering the French territory only occupied some insignificant villages and towns, and then stopped in front of the old French fortresses, fortresses and hastily deployed defense lines. The casualties of only thousands of people were insignificant losses compared to any battle since the outbreak of the war. Despite the unfavorable attack, the military liaison officials sent by the Italian Supreme Commander to Berlin were still proudly seeking credit from the Germans, claiming that the Italian army's military operations successfully contained tens of thousands of French troops on the border of the Italian border, making it impossible to mobilize them to the front line of confrontation between the German and French troops.

During the short three-day ceasefire period, the military and diplomatic representatives of Germany and France launched a fierce verbal battle in Lyon, which gave people the feeling that the weak side was asking for peace from the opponent, but moved the war from the front line of the battlefield to the negotiating table. The French's negotiating capital lies in the army with less than one million soldiers, in the Alps where modern war machines are still difficult to cross, in the French fleet, and in the loyal support of the French regime in African colonies. As long as the French insist on this war at all costs, they can even move government agencies to Algeria on the other side of the Mediterranean!

The problems that negotiations could not be solved were left to cannons and bayonets. Taking advantage of the three-day ceasefire period, the German General Staff adjusted the offensive strategy, from the original three routes to the two wings flying together. The left-wing heavy army group invested more than 400 armored combat vehicles and 500,000 troops, and launched a fierce attack on the last few port cities on the west coast of France with the support of the German fleet. It took only more than a week to place Paranti, Leon and Bayonne into the German occupied area; the main force of the right wing concentrated nearly a thousand armored combat vehicles, and advanced along the Rhone Valley with more than 700,000 troops along the Rhone Valley to the southern coast of France. In Valence, the two sides fought fiercely for five days. The German army defeated the last French new force at the cost of 100,000 casualties, and then conquered Pierrelat and Avignon. The German advance troops were able to see the blue Mediterranean from afar.

While the ground forces launched a large-scale offensive, the German aviation forces also showed the world the three-dimensional power of modern warfare. Zeppelin airship groups successively bombed Marseille and Nice southern ports one after another, shocking the French and civilians with the majestic momentum of dark clouds. With the completion of the construction of military airports around Lyon, German long-range bombers began to shuttle over the Rhone Valley. In addition, Italy, Austro-Hungarian Empire and Germany jointly formed a powerful alliance fleet in the Mediterranean. French ships stationed in Marseille and Nice military ports had to retreat to the Port of Algiers in North Africa in advance.

When it was discovered that the French main ships had left the southern port, the Alliance Fleet unscrupulously launched artillery and blockade on the French mainland. On April 13, the Alliance Fleet attacked the Port of Nice, and the fearless fleets of Italy and Austro-Hungarian Empire used ruthless artillery fire to turn this beautiful and pleasant coastal city into rubble. One day later, Cannes became the second French port to be razed to the ground. The sea access between the French mainland and the North African colonies was also greatly restricted as the Alliance Fleet was active everywhere.

On April 17, the French, whose front was almost collapsed, returned to Lyon. This time, they still had the unique arrogance of the Gauls, but their attitude in the negotiations had no confidence. The diplomatic representatives of Italy and Austro-Hungarian Empire gained a place at the negotiating table. The re-arms between the two sides lasted until April 25. When the dark night fell, the French negotiators signed the name on a truce letter that was harsh but could at least save the Third Republic of France from destruction. The battle on the Western Front, which lasted for nearly nine months, ended. In name, the French lost one-sixth of the original land area and nearly half of the colonies, including ceding to Germany.

The actual situation of the Ardennes region of the country and the island of Corsica, which was ceded to Italy, was much worse. France needed to pay the three countries of Germany, Austria and Italy a war compensation of up to 18.5 billion francs, which was equivalent to 3.7 times the Franco-Prussian war compensation. Before the compensation was paid, the German team will continue to occupy Paris and the eastern region east of Paris, as well as France's northern and western coasts, which means that the northern industrial zone centered on Paris and the eastern region rich in coal and iron ore will provide various industrial products and strategic resources for the German war machines for a long time in the future. In addition, Germany also forcibly obtained the use rights of important military ports such as Le Havre, Cherbourg, Brest, Saint-Nazell, and Nantes from the French.

With the signing of the Armistice Treaty, although the French team had not collapsed, the French giants had fallen. The economically struggling Tsarist Russian Empire could no longer receive a franc of assistance from French allies. Out of distrust of Britain, Nicholas II's army generals and powerful politicians almost unanimously agreed that Russia should withdraw from the war in time. At the end of April, the Tsar's envoy arrived in Berlin. At this time, the German team had occupied the rich Russian Polish region. They had no appetite for the land in the hinterland of Russia. The conditions for the armistice were to establish a reliable military buffer zone for East Prussia.

The independence of Thuania was a condition that the Russian rulers could accept. The two sides quickly reached an intention to make a truce. However, according to the German-Austrian alliance agreement, the formal peace between the two sides also required Russia and the Austro-Hungarian Empire to reach an truce agreement. The conflicts between St. Petersburg and Vienna have been a long time ago, and the armistice negotiations became a protracted tug-of-war. However, unlike the Western Front, the treasury that Russia and the Austro-Hungarian Empire were not fully filled have been completely defeated by the war, and the military and people did not agree to fight again. Therefore, the parties on the Eastern Front suspended military operations during the negotiations.
