Siam originated from the Sukhothai Kingdom established in 1238 AD, and later the Thai leader King Utong annexed the territory of the Sukhothai Kingdom and established the Ayutthaya Dynasty, also known as the Ayutthaya Dynasty, and the territory of Siam was roughly finalized.

At the beginning, Siam had many names, some were called Siam, some were called Luo Hu, and some were called Siam Hu, until 1377 AD, Ming Taizu Zhu Yuanzhang canonized King Ayutthaya as the "King of Siam", and the name "Siam" was officially fixed.

The relationship between Siam and the Ming Dynasty has always been very good, since the beginning of the Taizu Hongwu period, often send envoys to pay tribute, and the Ming Dynasty has never been stingy with rewards, and the two sides have come and gone, which has lasted for two or three hundred years. However, in the Wanli period, the rise of the Donghu Dynasty, Mubang, Mengyang and other Xuanwei Si territories were occupied by it one after another, and the land transportation between Siam and the Ming Dynasty was cut off, and since then there have been fewer contacts.

As for why Siam and Donghu fought, it is rumored that the king of Donghu fell in love with a princess of Siam and sent an envoy to propose marriage, but the king of Siam did not agree, and the king of Donghu was furious, so he sent troops to attack Siam, regardless of whether the rumors are true or not, Donghu and Siam did fight, and a fight is decades.

Now the life of the Siamese king Parasetong is very difficult, after all, Donghu is rich in most of the southeast peninsula, the national strength is much stronger than Siam, although Siam struggles to resist, but after all, the outnumbered can not be defeated, the gap in national strength is too big, not by courage can make up, so the situation is more and more unfavorable for Siam, defeat seems to be only a matter of time.

Just when the Siamese king Parasethong was about to fall into despair, the Ming envoy came from the sea, read out the "Ming Vassal State Decree", and asked him if he was willing to surrender completely!

To be honest, Paraseton was reluctant to accept it at first, and it was no problem to ask him to be called a minister, but it was a bit of a problem to let him directly accept the control of the Ming Dynasty, who didn't want to be free, especially the lord of a country, and listen to others, which was really a bit unacceptable.

Therefore, he hesitated in the face of the Ming envoy, of course, he did not refuse in person, just said to consider it, this consideration has passed more than a month, after the New Year, Donghu did not know whether he was instigated by the British and Dutch or took the wrong medicine, suddenly launched a fierce attack on Siam, seeing that the capital was going to be unable to defend, Paraseton finally couldn't bear it, he immediately sent a messenger from the sea to Xingcheng Port, informing the governor of Nanyang of the Ming Dynasty that Siam was willing to accept the "Ming Vassal State Command System", and asked the Ming to send troops to rescue.

Zheng Zhilong did not go to the capital to accompany the emperor for the New Year this time, after all, Nanyang is in a critical period, and it is not possible to have a big man in charge, Zhu Cijiong confessed before leaving, so that he was in charge of Nanyang.

After seeing the envoy of the King of Siam, Zheng Zhilong did not dare to slack off, and immediately sent a speedboat to Thang Long City in Annam, borrowing the telegraph system there to send a telegram to the capital.

Zhu Cijiong was dispatching troops and horses at this time, waiting for the Shenwei cannon, the production process of the Shenwei cannon is quite complicated, especially the mold is very time-consuming, so the delay is a little longer, as for the army, it is simple, he sent a telegram order, the Dongjiang army in Liaodong immediately rushed to the capital by train, and gathered in the capital in less than three days before and after.

However, at this time, Lu Xiangsheng, the commander of the Tianxiong Army, went to the capital to ask for guilt, he admitted his mistakes, and strongly asked for meritorious service, it turned out that when he commanded the siege of Thang Long City, he forgot to use a grenade!

In fact, it can't be said that he has forgotten, he used grenades when he commanded siege warfare, and those few times either the grenades have not been made, or the number of grenades is still very scarce, and he is not equipped with the whole army, he is relying on bravery, rushing to the city wall and the enemy is tough, although the Tianxiong army is equipped with grenades, but he is more anxious when attacking the city, plus he is a commander can not be equipped with grenades, so before rushing to the city wall, he did not let his soldiers throw two rounds of grenades and then rush up, but directly took the lead in jumping up!

If you throw two rounds of grenades first, the casualties of the siege soldiers will definitely not be so large, although the power of the grenades is not enough to blow people to death, but it can blow up the enemy to unbearable pain, panic, and even chaos in formation, in that case, the resistance encountered will be much smaller, and the casualties will not be so heavy, so he blames himself in his heart, and wants to follow Zhu Cijiong to Nanyang again to make meritorious contributions.

In the face of Lu Xiangsheng's invitation to fight, Zhu Cijiong was not very resistant, after all, bringing more men and horses is conducive to controlling the battle situation, and he has no sense of blame for Lu Xiangsheng's mistakes, anyway, there were heavy casualties before the siege, and throwing two more rounds of grenades will reduce casualties by thousands at most, and the final result is still the same, it is naturally impossible to blame his most trusted general for this unintentional mistake, he is just worried about Lu Xiangsheng's body, the so-called injury of the bone for a hundred days, this is only fifty or sixty days, he is so good that he is not so.

Faced with Zhu Cijiong's question, Lu Xiangsheng naturally patted his chest and assured that there was no problem, he was also worried that the combat strength of the Tianxiong Army under his command would decline, although the elite of the reserve army under his command was selected to supplement the battle damage, after all, they had not really been on the battlefield, and it was impossible to top those veterans who had experienced a hundred battles without training.

In mid-February, everything was ready, Zhu Cijiong once again personally conquered Nanyang, this time he decided to divide the army into two routes, one route Lu Xiangsheng led the Tianxiong army to take the train to Thang Long City, and then led the Dingliao Army, Wuwei Army and the Second Army of the Frontier Army there, while repairing the railway, marching from Annam to Champang, from Champa to Chenla's hometown, and then straight to Siam.

He personally led the First Army of the Praetorian Guard Army and the Dongjiang Army to set off from Dongdaying, and rushed to Siam by sea on the warships of the Beiyang Naval Division and the Beihai Fleet.

There are nearly 8,000 miles by sea from Dongdaying to Siam, although the large and medium-sized warships of the Beiyang Naval Division and the Beihai Fleet have been transformed into ships, and the speed is very fast, but it takes five or six days to travel day and night, Zhu Cijiong does not know how long the delay has been between coming from Siam to asking for help and receiving the news, he is really afraid that before his army arrives, Siam will be overturned by Donghu!

But fortunately, Siam is not a weak country, before Donghu did not rise, they were the strongest country in the Southeast Peninsula, even if Donghu is in its heyday now, it is impossible to easily take Siam, besides, the Guanning army is also a first-class army of the Ming Dynasty, not to mention that a legion can help Siam overturn Donghu, but it is more than enough to help them hold the city.

Therefore, when Zhu Cijiong led the army to Siam, the 200,000 troops of Donghu had already withdrawn the siege of Dacheng and retreated hundreds of miles, because the first-class army of the Ming Dynasty was too fierce, although they also had muskets and artillery, but compared with others, it was simply not a grade.

The cannonballs of the Guanning army are like rain, and the muskets are even less than the Annan army, and the Donghu army has even fewer artillery than the Annan army, and there are only a few thousand muskets.
