The March breeze blows across the land and the fields, and the land is full of spring and greenery.

In this wonderful time, Ferdinand lay quietly on the lawn, bathed in the embrace of spring, and felt the vitality of life.

"Your Majesty, something is wrong! The Hungarians had just announced their accession to the Entente this morning, and in the afternoon Budapest was attacked by the Germans, and they have now come to us for help! Foreign Minister Metev said calmly

Ferdinand could see that although he was talking about something big, the joy on his face could not hide his gloating!

In order to cooperate with the encirclement and annihilation of this German-Austrian army, the Ministry of Foreign Affairs had communicated with the Hungarians, but the Hungarians refused to disclose the time of their actions to Bulgaria on the grounds of secrecy, which made the Ministry of Foreign Affairs very embarrassed.

Ferdinand is not a generous person, since the Hungarians can't trust Bulgaria, he naturally won't go to the trouble, and now that the Germans have raided the capital of Hungary, it can only be regarded as the Hungarians' bad luck!

Anyway, Bulgaria's goal had been achieved, the Hungarians rebelled, and the Germans chose to raid Budapest, so the German-Austrian defense line on the Tisza naturally collapsed.

Now the Bulgarian army only needs to cross the river, and due to the defection of the Hungarians, the Austro-Crarian defense line in Belgrade will naturally not be able to hold it, and the small half of the Austro-Hungarian Empire is about to fall!

As for the Kingdom of Hungary, their lives or death are heavy? Anyway, this path was chosen by themselves, and such an important matter, they would leak the news in advance?

Of course, it would not be absolutely surprising if Ferdinand had been a little concerned with the Hungarian intelligence.

Even if it is to defect, a few people at the top of the government will know about it, and at most a few more powerful people in the country will know about it.

It's a pity that the Kingdom of Hungary actually stupidly held a general assembly, so that more than a hundred people knew about it, if the Habsburgs didn't even have a few diehards, how could they rule this empire?

Now that Austria-Hungary knows, it is natural to inform the Germans of the news, at least they will also borrow the hands of the Germans to kill a group of independents!

It doesn't matter whether Austria-Hungary made a deal with the Germans or not, anyway, Ferdinand didn't plan to care about the of the Kingdom of Hungary!

What if the Germans occupied Budapest? Without the cooperation of the Hungarians, they would not have been able to hold the Kingdom of Hungary.

"Asking for help? Let the Hungarians hold on, we are gathering troops and will definitely be in Budapest in half a month! Ferdinand said with a smile

Not to mention half a month, even a week the Hungarians could not hold out, and who said that their main forces were already almost consumed in the war?

With the rabble they gathered, it is undoubtedly a fool's dream to block the attack of more than 300,000 German troops!

It's not that Ferdinand deliberately tricked them, they dug their own pits and buried their own, and the Germans only found out under their noses, doesn't this explain the problem?

Even if there is the hand of Austria-Hungary in this, but you are all ready to turn against others, don't you even know that you will send a few more spies to keep an eye on the German army?

The Tissa River to Budapest is not close, and if you don't take the train, you won't be able to reach it in a few days, and tens of thousands of German troops have run under their noses, and they deserve to suffer before they have not found out!

Obviously, this time the Germans are trying to make an example, even if the Bulgarian army sets off immediately, they will have to cross the river? Ferdinand didn't think that the Germans had drained the defenders on the other side!

For the Germans, the abandonment of the Kingdom of Hungary was a foregone conclusion, and there was no need to continue to fight with the Bulgarians!

But to slow down the Bulgarian army and teach the Hungarians a lesson, they also had to do it!

After sending Metev away, Ferdinand said to his attendants: "Send a telegram to the Balkan Regional Command, asking them to take Belgrade while the current internal strife in the Allies is in good condition, and if conditions permit, they can also take Bosnia and Herzegovina." ”

The Hungarians made the life of the Allies even more difficult, and Ferdinand was the only one who wanted to fall to the ground?

The first was the all-out counteroffensive launched by Britain and France on the Western Front, and their aim was simply to hold back the Germans and make them unable to support Austria-Hungary.

At this time, the Russians could not bear it anymore, and on the third day of Hungary's defection, the Russians launched a campaign to recover Ukraine, and the German army was in an emergency on the eastern front.

On the Italian front, Valikot also led the Allied forces to attack Austria, and the air forces of Britain, France and Bulgaria plundered over Vienna!

The full-scale outbreak of the Entente, the Germans were dumbfounded, and now they are blooming on all sides and cannot take care of each other, what should they do?

Reinforcements were needed everywhere, and the Germans had limited reserves to commit to multiple battlefields at the same time, and a considerable part of the population in Germany became pessimistic about the war.

Compared to the Germans, the situation of the Vienna government is much worse, and now many of them are beginning to regret it, if they had known that this kind of thing would happen, they would have jumped directly and calculated it, it is better than letting the Kingdom of Hungary jump ship first, as it is now!

Austrian Emperor Ferdinand II also began to worry, seeing that the Central Powers were about to end, what should Austria-Hungary do?

Now that the Kingdom of Hungary has jumped ship, although they may be suppressed by the Germans, the Entente has recognized their accession, which is very bad for Austria-Hungary politically!

Who knows if in the future the Entente will support the independence of Hungary and dismember the Austro-Hungarian Empire? This consequence is much more serious than the annexation of Serbia and Bosnia and Herzegovina by Bulgaria, even if it is much more serious than the annexation of Poland by the woolly bear!

The Austrian Foreign Minister said worriedly: "Your Majesty, the Bulgarians have put forward new conditions, and they have asked us to give an answer at once, otherwise Vienna will be in ruins!" ”

Obviously, this is already blackmail by force, but do they dare to gamble? Theoretically, the Entente could now drop hundreds of tons of bombs on Vienna every day if they wanted to, and perhaps in less than two months, Vienna would really be in ruins!

On the issue of air supremacy, even the Germans are powerless now, otherwise they would not have been suppressed to death by the British and French air forces on the Western Front!

In the case of a small gap in quality, quantity is the key factor that determines the outcome of the war, and it is clear that the Entente has an absolute advantage in this regard!

By 1917, the industrial capacity of the two Allies had become completely unbalanced, and it could be said that for every aircraft built by the Allies, the Allies could build two or three!

Who said that the United States had become the arsenal of the Entente? The Entente, which had already had an industrial advantage, now had an even greater advantage!

Emperor Ao asked coldly, "What kind of conditions did they put forward?" ”

The Foreign Minister hesitated and said: "The Bulgarians demand that we cede all Serbia and Bosnia and Herzegovina, and in return they will oppose the dismemberment of Austria-Hungary, try to ensure the territorial integrity of Austria-Hungary, and give up demanding reparations from Austria-Hungary!" ”

Ferdinand II still said in a cold tone: "They are going to annex Bosnia and Herzegovina and Serbia, what else are they talking about keeping Austria-Hungary territorially intact?" ”

After saying that, the temperature in the room seemed to return to the cold winter moon again, and after a moment of silence, Ferdinand II said coldly: "Promise them!" ”

Obviously, he was very reluctant to accept this condition, but in the end he decided to compromise. The reason is very simple, with the defection of the Kingdom of Hungary, whether it is Serbia or Bosnia and Herzegovina, Austria-Hungary cannot hold it!

If it wanted to stay and fight the Bulgarians, Austro-Hungarian would not gain anything but more casualties.

Rather than that, it's better to trade some benefits. If nothing else, this world war has already been won by the Entente, and the Austro-Hungarian Empire will inevitably be divided after the war, and it will depend on the means of the Habsburgs to leave a few pieces of family wealth in the end!

Of course, this is just a deal to fool the domestic on the surface, in fact, the two royal families have already reached an insider deal.

For example, if the Entente were victorious, the Kohali family would do their best to keep Ferdinand II's throne and, at the worst, one of his crowns; In return, the Habsburgs would ensure that the Kohali family's property in the Austro-Hungarian Empire would not be lost.

Another example: if the Allies were victorious, the Kohali family would transfer all of the Austro-Hungarian estate to the Habsburgs in exchange for the Habsburgs' efforts to retain Ferdinand's throne.

……

There is no way to do it, before the outbreak of the war, Ferdinand began to transfer property, but unknowingly, his industry has grown and penetrated into many industries, and it is not so easy to retreat.

Cutting the meat in half, this is a must, and even then it has not been able to sell much. Who made Ferdinand ignore that the European continent was already swept away by an economic crisis before the outbreak of war?

So this deal appeared, anyway, Ferdinand's strategy was to try to keep Austria-Hungary as much as possible, and it was not contradictory to this deal!

Kings are also human beings, so naturally they also have to consider personal interests and family interests! As the old nobles of Europe, whether it is the Kohali family of the Gotha dynasty from Ferdinand, or the Habsburg family, they are all masters in this regard, otherwise they would not become the top families in Europe!

This was only a small episode, and the most important thing was that Ferdinand II agreed to give up Serbia and Bosnia and Herzegovina, which made it possible for Bulgaria to pay a small price. You can complete the great cause of unifying the Balkans!

Of course, the war still has to be fought, and the drama must also be done in a full set, otherwise if it is a goof, the Germans will not let Austria go!

On March 12, 1917, the Bulgarian Balkan Theater sent 800,000 troops to outflank Belgrade from the Kingdom of Hungary in two ways.

On March 20, the Austro-Hungarian army, besieged in Belgrade, laid down its arms and surrendered to the Bulgarian army.

From the outbreak of war in 1915 to the two-year Battle of Belgrade, the curtain finally came to an end.

This battle was the largest, longest-lasting, and most casualty battle on the Southern Front.

By the end of the war, Austria-Hungary had suffered 1,029,000 casualties, including 168,000 dead, 287,000 disabled, and 368,000 captured, while the Bulgarian side had paid 895,000 casualties, including 76,000 dead, 95,000 disabled, and more than 3,000 captured.

With the fall of Belgrade, the world was in an uproar again, and many were predicting when the Allies would be finished!

Before everyone could recover from the news of the end of the Battle of Belgrade, on March 26, the Russians won the Battle of Ukraine on the Eastern Front again, taking back almost the entire Ukrainian region!

Well, this battle on the Eastern Front is a passing one, less than 300,000 German troops in the Ukrainian region, in the face of the attack of more than two million Russian troops, it is natural to retreat strategically, but this does not prevent the Russians from winning this big war!

Immediately afterwards, the Bulgarian army began to sweep through the Serbian region, and then the troops approached the Bosnia and Herzegovina region, and in the face of the siege of a million troops, the Austro-Hungarian army in Bosnia and Herzegovina naturally had to retreat strategically!

The battle between the two sides continued until April 11, when the Austro-Hungarian army retreated to the Croatian region, and the Bulgarian army stopped the pursuit.

During this period, the Allies were not without gains, such as: Marshal August von Mackensen was still young, the Hungarians rebelled on March 1, the rebellion was extinguished on March 4, and the Hungarian hopes were shattered in just three days!

Due to the short time, the Bulgarian reinforcements had not yet arrived halfway, so they had to cancel the reinforcement plan, although they were not intended to reinforce them, but it still looked like they had to be enough!

Then the reinforcements went straight from Hungary to outflank Belgrade, ending the protracted battle!

With the start of Bosnia and Herzegovina, the last remaining territory of the Balkan Peninsula was also included in the hands of Bulgaria, and after a thousand years, the Balkan Peninsula was once again unified!
