The Ninth Army has a total of 500,000 people, and it is impossible for these 500,000 people to be sent to the battlefield all at once, Cai Wei divided the 500,000 men into two parts: the first part is the main battle force, a total of 300,000 people, which is reorganized into 15 divisions and regiments, each with 18,000 people, and these 15 divisions and regiments are reorganized into five armies, namely the 1st Army, the 2nd Army, the 3rd Army, the 4th Army and the 5th Army of the Ninth Army Corps; The second part is the reserve force, a total of 200,000 people, also called the supplementary force, as long as there are losses of soldiers on the front, it will be replenished from these 200,000 people.

On the morning of 26 May, the Ninth Army was approaching the Austro-Hungarian-controlled zone in three parts, the first of which was to advance west from Novi Sad in Serbia along the north bank of the Danube, followed by the Second Army and westward along the south bank of the Danube, two hours apart, west along the north and south banks of the Danube.

On the second road, the 3rd and 4th armies of the 9th Corps proceeded from Zrenjanin and advanced northwest along the Tissa River, a tributary of the Danube.

On the third road, the Fifth Army of the Ninth Army Corps was behind the first and second roads, and Cai Wei's headquarters advanced with the Fifth Army, whose role was to protect the security of the headquarters and support the other two armies at any time.

On the night of the 26th, the forward troops of the Second Army quickly attacked along the south bank of the Danube and occupied the riverside town of Iroke, and the next morning they arrived on the outskirts of the city of Vukovar and immediately launched an attack on the Austro-Hungarian division stationed in the city. The Austro-Hungarian army was completely stunned without reacting, and did not carry heavy equipment because the forward troops required a fast march. The 4th Division of the 2nd Army used a large number of mortars and grenadiers to cover the infantry charge, thanks to the fact that the 1st Army left a large amount of good equipment, the Japanese army had only had mortars and grenadiers before, but there were not many equipment, and some soldiers could use it, and after coming here, they had two weeks to familiarize themselves with the equipment and training, so the Japanese artillery was not very proficient in edible mortars and grenadiers. But anyway, it will still fire, but it is just a little worse than the head.

Heavy artillery fire covered the infantry charge, and the Japanese infantry, after paying some casualties, rushed into the defensive positions set up by the Austro-Hungarian army. The two sides immediately held a white-knuckle battle, and the Japanese army's training in this area was almost beyond that of any other country in the world at this time, and the Japanese soldiers' skillful bayonet fighting skills made the Austro-Hungarian soldiers fearful. The Austro-Hungarian troops in defensive positions did not engage in such a level of white-knuckle combat at all. Soon collapsed, the soldiers of the Fourth Division of the Second Army immediately took advantage of the victory to pursue, and the rout on one line of defense soon affected the entire defense line, in less than ten minutes, all the Austro-Hungarian troops of the defense line were scattered, and the Japanese soldiers pursued behind, the Austro-Hungarian army suffered numerous casualties, and more than half of the Austro-Hungarian army of a division was killed. Less than half were captured, less than a morning. The 4th Division captured the city of Vukovar.

On the morning of the 28th, the Fifth Division of the Second Army arrived to take over the baton of the Fourth Division and continue to advance northwest along the Danube, while by this time the First Army had captured the city of Ozazi north of the Danube.

On the morning of the 29th, the 5th Division arrived at Osijek and launched an attack at any time, north of Osijek was the Danube tributary of the Dlao River, where Austria-Hungary had the strength of a division and a night defense system, and the 5th Division did not rush into attack, but waited for the arrival of heavy equipment before launching an attack.

The power of heavy artillery is definitely not comparable to that of mortars and grenadiers, and the artillery blow brought by an artillery brigade covered the entire city of Osijek.

In the positional warfare, the Japanese army rushed over like a tide, wave after wave, as if it would never stop, the Austrian army was not at all suitable for the Japanese army's suicidal bayonet charge, the fifth division only used two waves of charges, the Austrian army could not withstand the collapse, the scene of white knives entering and red knives out was too terrible, it is no wonder that the Austrian army was in the bag, even if the armies of Britain, France, the United States and other countries were not necessarily able to withstand the bayonet impact of the Japanese army.

Once the nature of the killing, the murderous character of the Japanese army is exposed, and the commander can't take it back many times, after all, the Ninth Army is not the Wehrmacht, Cai Wei is blind to it many times, as long as he can win the battle, he will relax the military discipline after the battle, Cai Wei will just not see it, but if the attack is unfavorable, Cai Wei's ruthlessness will come up, for those Japanese commanders who command unfavorably or improperly, he should not be soft at all, after winning the battle, some troops and commanders who want to be commended, He also did not hesitate to give awards and rewards, and many Japanese commanders were subdued by his set, and did not hesitate to suffer any casualties during the attack, as long as they could complete the combat mission, no matter how many soldiers were lost, the rear would have enough troops to replenish them.

The Fifth Division invaded Osijek, and carried out a large-scale killing in the city, whether it was the Austrian soldiers or Austro-Hungarian civilians who fled into the city, thousands of people were slaughtered, and the Japanese army was worried that the matter would be discovered by the Chinese officers, so all the corpses were secretly buried, and the Japanese soldiers even carried out a large-scale weapon fight for the booty, but at this time it was suppressed and quelled by the Japanese high-level.

Every division, hotel, wing, and even brigade of the Japanese army has officers and gendarmerie units of the Chinese army, and the fact that the Japanese army massacres civilians and secretly buries them still cannot be concealed from the officers and gendarmerie units of the Chinese army, but this kind of thing really cannot be completely eradicated, and the inspectors of the Chinese army and the military police can only supervise the efforts of the Japanese army to fight, and there are no incidents of desertion.

The Third and Fourth Armies of the Second Route were also divided into two routes, the Third Army first captured Zabali, then Bechey, and then moved westward to attack Turia and Vrbas and Kurla, and after capturing Kura, the troops were again divided into two routes, all the way to Crvenka, and all the way north to Bazi.

The Fourth Army quickly advanced to Jinda, defeated the 30,000 Austrian troops of Jinda, and then continued to advance northwest to the area of Tsoka and Orkali.

On 6 June, the 3rd Army of the 9th Army captured Subotica, the northernmost city in Serbia, and the remnants of the Austrian army fled with thousands of men. At this point, all the Austrian troops withdrew from Serbia, and the entire territory of Serbia was recovered.

On 8 June, the new Serbian Government sent a telegram of thanks to the Chinese Presidential Office, saying that the Serbian Government is grateful to the Chinese Government for its tremendous sacrifices in the process of striking at the Central Powers and restoring Serbian territory, and that the Serbian Government has decided to build a monument in Belgrade to commemorate the fallen soldiers of the Chinese army after the government's affairs are on the right track.

At the same time, the attack of 1.5 million troops of the Balkan coalition army on the southern front did not make much progress, which made the position of the Ninth Army too prominent, and once the Austrian army in the south moved north, it was very likely to cut off the supply lines and retreat routes of the Ninth Army.

Cai Guodong saw this, so he was extremely indignant at the slow progress of the Balkan coalition army, and for this reason, he sent a telegram to the country, hoping that the authorities would immediately consult with the Balkan governments and demand that the command of the 1.5 million army be placed under his command, otherwise according to the progress of the Balkan coalition army, it would only delay the Chinese army and would not play a role at all.

After receiving Cai Guodong's telegram, Xiao Zhenlei summoned Jiang Fangzhen and the members of the staff group to discuss the matter, and after reading the telegram sent by Cai Guodong, Xiao Zhenlei asked: "Everyone, what do you think about this matter?" ”

Jiang Baili first said: "President, from a military point of view, unified command is definitely beneficial to the war situation, now the armies of those Balkan countries go their own way, there is no unified command, so when they are fighting, they always blame each other, lest their army lose too much, and worry that their war materials will be consumed too much, if this situation of passing the buck continues, the 1.5 million army will not play a role at all, General Cai Guodong's request is reasonable and reasonable, Only by taking the command of the 1.5 million army into the hands of General Cai Guodong can we strike a good blow at the German-Austrian army on the Eastern Front, and now the 1.5 million Balkan coalition army not only does not play a role, but also consumes a lot of war materials, and it is just a matter of consuming some war materials, the key is that they are dragging us back! ”

Yang Shiqi said: "Yes, President, Chief of General Staff Jiang is right, put these aside, the armies of Britain, France, the United States and other countries on the Western Front have formed a coalition army, with a unified command, which is conducive to concentrating forces to exert maximum combat capability, and it must also be like this on the Eastern Front, in fact, on the Eastern Front, the total strength of our army plus the Balkan Coalition Army is not the small number of troops of Britain, France and the United States, if we can take over the commander of the 1.5 million coalition forces, then we will use more than 3 million troops, A lot of strategic intent can be achieved."

Xiao Zhenlei nodded and said: "Yes, judging from the current situation, if the Balkan coalition army does not do anything about the 1.5 million army, the position of the Ninth Army will be too prominent, this is very dangerous, it is necessary to take over the military power of the 150 army, but it is not a simple matter to take over the military power of the 1.5 million army, we need to send a competent and eloquent person on our side, I don't know which gentleman is willing to take this trip?" ”

Yang Shiqi stood up and said: "The great president, if the great president does not dislike the low ability of the remnants, he is willing to go and persuade the Balkan governments to agree to hand over the military power!" ”

Xiao Zhenlei was overjoyed, and immediately said: "Okay, I believe that if Mr. Yang comes out, he will definitely succeed!" I have appointed Mr. as the special envoy of the president, and this time I will go to Europe to take charge of this matter, and I will telegraph to General Cai Guodong and let him cooperate with you! ”

"Yes, Shiqi will definitely live up to the president's trust!" (To be continued......)
