In early July, the 2nd and 5th Corps of the Chinese Army moved south along the Black West Bank, taking Floksani, Galatz, Buzeu, Breira, and Tulcha.

On July 7, the Fifth Army advanced to the southwest, captured Ploiesti and Pitesti in succession in three days, and approached Bucharest from the north and northwest. In this series of attacks, the Chinese captured more than 120,000 German-Austrian troops.

On July 8, 80,000 men of the 2nd Army of the East Bengal Army attacked Hasowa, which was defended by less than 5,000 men, and after holding out for two days, the remaining 3,000 men surrendered, and the East Bengal Army lost 1,200 men.

On July 9, the East Malay Army of 70,000 attacked Slobozia, which was garrisoned by 20,000 Austro-Hungarian troops, and besieged it, this is a small city, with more than 30,000 residents, but the geographical location here is special, it is on the banks of the Yalomica River, only 90 kilometers away from Bucharest, the capital of Romania in the west, if it is captured here, then Bucharest, the capital of Romania, will be attacked on three sides, with a total of 1.5 million troops in the north and south of the Chinese army, the strength of the German and Austrian troops in this area is not an opponent at all, It was only a matter of time before it was lost.

The Austro-Hungarian army of 20,000 men had to surrender after four days in Slobozia for several reasons, the first being the lack of ammunition reserves. The second is that the will to fight of the Austro-Hungarian army has been crushed by the Chinese army all the way south, and these more than 20,000 people have not been stationed here all the time. Instead, after retreating here, he received an order to hold this place, which is a pity. The 20,000 Austro-Hungarian troops ran out of ammunition and food after ten days of fighting, and the Austro-Hungarian army, which had long since lost its will to fight, surrendered under the leadership of the commander after losing 6,000 men, and the Chinese army only captured more than 13,000 prisoners who needed to eat and tens of thousands of guns that were empty of ammunition.

On July 11, 180,000 Japanese, Korean, Vietnamese, Laotian, and Cambodian troops arrived 30 miles north of Constanta on the western shore of the Black Sea. On the 12th, the armies of the Five Nations were ordered to launch an attack on Constanta.

Constanta is a city garrisoned by the German 41st Army, which is very important, it is one of the important cities for the German army to defend against the Chinese army from the Black Sea, and the German 41st Army stationed in this area has a total of 60,000 men and a total of five divisions. Two cavalry divisions and three infantry divisions.

One was deployed at Mufatra to the west of Constanta as a flank, two cavalry divisions were deployed at Kunbernar to the south, and the remaining two infantry divisions were deployed in Constanta.

The Chinese army divided the 50,000 Lao army and marched west to pin down and monitor one German division in Mufatla, while the rest of the army stormed two German divisions in Constanta. The Germans adopted a strict defensive approach, and on the other hand, the two German divisions deployed at Kun Bernard were drawn from the two divisions in order to use this as a partial division to bypass Murfatra from the west.

However, the commander of the Second Army, Zhang Xiaozhun, had long thought that the Germans might use those two cavalry divisions to make a detour and surprise attack, so he specially arranged for the Burmese Army and the West Malayya Army to be deployed in Megidia, northwest of Mufatla. He also ordered 20,000 men to be secretly transferred from the Lao army of the German army pinning down Mufatra to retreat to the northwest to cooperate with the two German cavalry divisions of the Burmese army in Megidia and the surprise attack of the West Malayan army.

The two German cavalry divisions, unaware of the traps ahead, crashed headlong into the encirclement carefully arranged by the Chinese army, and the two German cavalry divisions immediately organized a breakthrough after discovering that they had crashed into the encirclement. Moreover, the chosen direction of breakthrough is still a weak point in the encirclement of the Chinese army.

The Chinese commander also knew that the weak points of their encirclement would definitely be the main breakthrough point for the German army, so they deployed a large number of machine-gun crossfire in these weak points. The Germans, unaware of the weakness of the encirclement, had deployed a large amount of machine-gun crossfire, but they had been organizing their forces to charge through these gaps.

The Germans proved their bravery and fearlessness to the Chinese army with a large number of corpses. Within two hours, more than 7,000 cavalry from the two German cavalry divisions had lost 4,000 casualties. The remaining 3,000 cavalry saw that there was no hope of breaking through, and had to surrender led by the German cavalry commander Oforta.

After two cavalry divisions were completely annihilated. The two German infantry divisions in Constanta had learned the news that the commander of the German 41st Army, Leo Walker, had already had the idea of withdrawing, but it was not easy to withdraw at this time, and the Chinese army had completed the encirclement of Constanta.

After five days of fierce fighting, the Germans ran out of ammunition and made several unsuccessful attempts to break out, so Leo Walker surrendered to Zhang Xiaozhun of the Chinese Second Army on July 16 with the remnants of 23,000 men.

After the conquest of Constanta north, the Germans were devoid of forces in Romania south of the Danube, and the Chinese army then conquered Mangalia and Silistra on the Danube.

Under the command of Zhang Xiaozhun, the Chinese army advanced west and south, and within a few days, the military and economic town of Ruse, an important military and economic town on the Danube, was quickly conquered by the Chinese army, so that the 300,000 German-Austrian troops in Bucharest were under siege.

In order to avoid being encircled, the German high command ordered the 300,000 German-Austrian troops in Bucharest to retreat westward, preparing to retreat over the southern section of the Carpathian Mountains in Romania and Serbia in the direction of the Tiemen Gorge.

Dividing the Carpathians and the Balkan Mountains into two sections, the Iron Gate Gorge is a military strategic location with steep terrain and long, narrow gorges, which are easy to defend and difficult to attack.

The Chinese offensive force has not yet penetrated deep into Serbia, and can only watch the 300,000 German-Austrian troops slip away, but the Chinese army is not reconciled, Zhang Xiaozhun contacted the air force in Turkey and wanted to use the air force bomber group to pursue the bombing, and the plane group had to stop bombing after bombing once, the main reason was that the German-Austrian army retreated too quickly, and the base of the Chinese air force was on the Asia Minor Peninsula, and the range was not enough, so it could not be bombed.

The Second and Fifth Army Corps then captured Bucharest, capturing all parts of Romania in the eastern Carpathian Mountains in just one week, and capturing all the officials of the Romanian puppet government supported by the Germans.

The Chinese army was worried that the consumption was too great to replenish in time, so they confiscated all the grain and property seized by the Romanian puppet government, and locked up a large part of the rich Romanian merchants who had colluded with the German army and confiscated their property.

There were a few small arsenals in Romania, which were barely able to meet the needs of the army in the country before the war, and the Germans did not look down on these machines after the occupation of them, so they did not pay much attention to them, and the machines of these arsenals were retained, and the Chinese army immediately reassembled the workers after taking over these arsenals, and let them produce ammunition for the Chinese army, and at the same time procured surplus food from the civilian population to make up for the shortage of the army.

On July 18, the First Army of the Chinese Expedition conquered Sofia, the capital of Bulgaria, and the 200,000 German-Austrian troops trapped in various parts of Bulgaria panicked, and the German-Austrian troops began to assemble, preparing to concentrate their forces and retreat westward after the assembly in Plovdiv.

Wu Shiyou, the commander of the 1st Army, commanded the army to break the German-Austrian forces and prevent them from completing the assembly. By July 21, only 80,000 of the 200,000 German-Austrian troops in Bulgaria had been surrounded by Chinese troops in Plovdiv, and these 80,000 German-Austrian troops were then taken prisoner.

On 25 July, the 1st Army and the 2nd and 5th Army Corps completed their rendezvous at Ruse on the banks of the Danube, and strategically trained together, so that the 1st Army Corps and the 2nd and 5th Army Corps could support each other and have sufficient strategic detour space and depth.

In the city of Rusai, Cai Yi, commander of the Eastern European Theater Commander's Department, Zhang Xiaozhun, commander of the Second Army Corps, and Zhou Chuandong, commander of the Fifth Army Corps, met with Wu Shiyou, commander of the First Army Corps.

"General Songpo, I haven't seen you for a long time, your body is finally healthy, it is really gratifying, and now you are wearing up again, and you have swept hundreds of thousands of people in the German and Liang army in a battle, which is really powerful, and I admire it!" Wu Shiyou stood up and saluted after seeing Cai Ye, and said these words with emotion.

A few people here returned the salute, and Cai Ye smiled and said: "I still want you to remember, I really don't want to go, thank you very much!" Although my side has made some small achievements, it is still far behind yours, and your army of 300,000 people is less than the Arabian Peninsula and the Middle East. Asia Minor Peninsula and the Balkan Peninsula, which are rare in history, you Wu Shiyou is already the world's number one famous general! ”

Wu Shiyou hurriedly said: "Where, where, outsiders don't know, General Songpa should be clear, my first corps is the most elite part of the national defense army, whether it is the quality of individual soldiers, or weapons and equipment, or grassroots officers are among the best, it is normal to have such a record, but General Cai's two corps in the Eastern European theater of operations are different, the fifth corps is later, and the combat effectiveness has been reflected in this battle, and the second corps is a mixed formation of Southeast Asian natives, and the combat effectiveness is not worth mentioning. Even under such circumstances, under the command of General Songpa and General Yunnong, these achievements were still achieved, and these achievements were not so much the achievements of the Second and Fifth Army Corps as the superb command art of several generals! ”

Cai Yi said with a smile: "I haven't been here for a long time, in the early stage, it was mainly Yunong in command, and later Yao Qinian's Fifth Army joined in, the battles east of the Eastern Carpathians are basically commanded by Yunnong, Yao Qinian's Fifth Army is strong in combat, if it weren't for the strong combat effectiveness of the Fifth Army, our advance speed would not be so fast, it is because we attacked too fast, so that the German army did not have enough time to arrange defense, I just coordinated in the center."
