The sudden attack from Austria-Hungary hit Serbia with a slap in the face, and the Serbian army itself suffered heavy losses in the first and second Balkan wars, especially the second, under the sudden intervention of Turkey, if it were not for the support of Britain and France, it might have been completely annihilated.

A small European country, without much history, and not much savings, was pushed out by Britain and France as a bird, happy to reward a few, unhappy, just ignored, Serbia did not return to the state before the first Balkan War, coupled with the sudden attack of Austria-Hungary, early concentration of 3 army groups, almost 300,000 troops, all of which were strictly trained elites, although during the First World War, the Austro-Constitutional army was not very good, and it ran into a second-rate army of Russia, It was also the annihilation of the legions and legions, but in any case, it was also a trained soldier who was equipped with a large number of artillery and machine guns, and had unified weapons, which Serbia could not resist.

Within two hours, two divisions on the Serbian border were scattered and fled, and Serbia's national border was suddenly wide open, and the Austro-Hungarian army of the three group armies, divided into three routes, rushed along the highway towards the hinterland of Serbia.

Faced with such a situation, Serbia declared war on Austria-Hungary at the first time, issued a national mobilization, and all young people of appropriate age joined the army. With a total population of less than 3 million, an army of 600,000 was raised at once. Far more than one-tenth of the maximum mobilization of other countries.

Against the backdrop of the country's demise, Serbia has developed a strong resilience. Even if it can't resist, it will fight for casualties, gradually resisting the Austro-Plevian army, and in the end, the speed of Austria-Hungary slowed down slightly, and the mortality rate increased, and Serbia breathed a sigh of relief and began to ask Britain and France for help.

The Balkans are the focal point of Europe. Before, it was just the internal friction of the Balkans, even the intervention of Turkey was very sensitive, not to mention the Austro-Hungarian Empire, which was a first-class power, in World War I, Austria-Hungary was a scumbag, but millions of troops, almost all types of weapons production capacity, and even the construction of battleships, such a power. It is not a small country in the Balkans that can resist, not to mention that the direction of the main attack is Serbia, which Russia has always regarded as its own forbidden territory. For the sake of the Balkans, more than a dozen Russian-Turkish wars were launched in a row, and gradually approached the Balkans. Now that Austria-Hungary has come to pick peaches, how can it be accepted. When the rest of the Entente did not react. Russia was the first to react and issued an ultimatum to Austria-Hungary. In the form of a general mobilization, it was indecent to demand that Austria-Hungary return to the negotiating table and withdraw from Serbian territory.

How could Austria-Hungary accept, not to mention its relations with Russia, but also the support of Germany behind it, and it was impossible to retreat, the most advanced army had already entered Serbia 30 kilometers, and tens of millions of apprentices were occupied, which was a good opportunity for expansion.

Immediately after Russia, France is the second to issue an ultimatum, France has many interests in the Balkans, coupled with close relations with Russia, has always been the same advance and retreat, if Austria-Hungary extends its hand to the Balkans, it is equivalent to saying that it is in the Mediterranean, firmly punched a nail, which France cannot accept, the day after Russia issued an ultimatum, made the same threat to Austria-Hungary, if Austria-Hungary does not immediately withdraw from the Balkans, they will also be the same general mobilization, And prepare to enter a state of war.

The situation in Europe, under one action of Austria-Hungary, became extremely tense, and it was already tense, but now it is simply trying to see the dagger. Austria-Hungary was destined to disappoint Russia and France, not only did they not listen to the ultimatum of Russia and France, but went further, the front of the army approached the capital of Serbia, and began to clear the strategic points on the road, the speed was very fast, without training, but with blood to resist the Austria-Hungary army The Serbs began to break and flee, their three-plank axe, after being familiar with the regular army, the impact on the regular army was greatly reduced, but in the rear, in the cities occupied by Austria-Hungary, the resistance movement was intensifying, and the results were gradually improving.

Austria-Hungary, with practical actions, rejected the demands between Russia and France, Russia and France were almost furious, almost in the shortest possible time, Russia and France announced a general mobilization, that is, the whole country into a state of war, the army began to mobilize, towards the border with Austria-Hungary, ready to force armed intervention.

At the same time that Russia and France launched a general mobilization, on November 2, Germany issued a note to Russia and France, exerting pressure on Russia and France to cancel the general mobilization, and after being refused, Germany also began to announce a national mobilization.

In the eyes of Britain, things have come to this point, Austria-Hungary will hardly retreat, Russia and France are destined to declare war on Austria-Hungary, Germany will definitely come to ask what Britain means, when the time comes, Britain can have a lot of choices, and even tease Germany, in short, Germany can delay Germany for 20 to 30 days, but I didn't expect that Germany directly ignored them, and only unilaterally proposed a general mobilization, which was beyond his expectations. What the hell are they trying to do.

Britain had not yet realized that this qiē was all planned by Germany, and the mobilization order had been issued more than ten days earlier, and the first wave of attacking troops had already set up troops on the border and could surprise out at any time. In order to prevent Austria-Hungary from independently resisting the attack of Russia and France, on November 3, Germany declared war on Russia and France at the same time. At the same time as receiving the declaration of war from Germany, Russia and France declared war on Germany, and the four major countries of the Entente and the Central Powers declared war on each other, and the First World War officially broke out.

The dazzling changes, from the very beginning of the change, to the whole of Europe declaring war on each other, into a state of war, it seems that it only took a few days, a qiē has become uncontrollable, even if it has been psychologically prepared, knowing that it will break out, but also feel a burst of loss, as the boss of the world, this war, seems to be intentionally or unintentionally isolated from it, very unhappy and unhappy.

Britain did not stay long, and the Foreign Office spent most of the afternoon coming up with an article on many inconsistencies in Germany, in short, many of the inconsistencies of Germany, and in the end, war was declared on Germany and Austria-Hungary, and the main forces of the Entente were all involved in the war. Immediately afterwards, Turkey declared war on all the Entente powers, and the Entente countries also declared war on Turkey. However, in the meantime, Italy, a member of the Central Powers, remained neutral, and among the major countries of the Entente and the Central Powers, except for the strange Italy, the others directly entered a state of war, and the whole of Europe was filled with war.

In addition to the Northwest which has been prepared for a long time, Japan, the United States, and Europe in many small countries, Canada and Australia, seem to have been suppressed by this large-scale war, and for a time all the diplomatic rhetoric was silent, and the war broke out so suddenly, all over Europe, the great showdown between hundreds of millions of people, and the smoke of war, from south to north, permeated the sky over the whole of Europe.

The Northwest General Staff, the newly arrived telegram, the news of the official war between the Entente and the Central Powers, directly got to the General Staff, the staff officers who were originally half-convinced, their faces seemed to be beaten, and the most unlikely thing happened, the war that could have started in three months, or even four months, actually happened within 10 days, and at this time, the two escaped British intelligence officers could not escape from Borneo at all, and most of the plans made before were done in vain, Only Yang Yuanzhao has always demanded that under the premise that most of the British and French forces are limited to Europe, they can have limited direct support for the Netherlands, and as for the British Asian Fleet that is close at hand, it is natural that the Germans will deal with it, and the previous East Asian Fleet is enough to confront the British, not to mention that now, there are more 600,000-ton warships including 9 capital ships.

Although the sea trials have not yet been completely over, but more than three months of high-intensity training, has made most of the German sailors, can successfully operate these warships, the most critical power system, weapon system and protective armor have all been installed, the soldiers have also run in eighty or ninety, against the powerful British home fleet, still need a little heat, but for the backward, only one battle cruiser, the rest is the former dreadnought and ordinary heavy patrol of the Asian fleet, it is simply an overwhelming advantage.

In the world, in addition to the United States and China, the four largest industrial countries and a bunch of second-rate powers, the scene of a war mobilization is really shocking, the Balkans have been raging, France and Russia have also begun to mobilize troops on a large scale, but it takes time, maybe a week or half a month, Britain and Germany should be about the same, maybe Germany is a little faster, but it will take two or three days.

However, Germany was fully prepared, and the first target was not France, nor Russia, but Luxembourg and Belgium, which puzzled many historians in later generations and questioned Germany's conspiracy theories, but in any case, on November 3, that is, the day Germany declared war on Russia and France, a declaration of war issued by Wilhelm II himself was directly handed over to the Belgian king, who was still shouting for neutrality and peace, and Germany declared war on Belgium, which was neutral and did not belong to the Entente camp.
