However, the ministers of the court and the central government had different opinions on which to send into Guangzhou to quell the rebellion, among them, the Northern Expeditionary Army that promoted Hua'an had the largest number of people, and Hua'an also took the initiative to ask Ying to lead troops to suppress the South Vietnamese rebellion when he heard about it.

After some consideration, the imperial court thought that it was enough for the Jingzhou and Yangzhou legions to defend Zhao, and the Northern Expeditionary Army could just draw troops to quell the rebellion in the Jiaoguang area, so it agreed to Hua'an's request and let him lead 30,000 main forces to Jiaoguang and Erzhou to quell the rebellion.

Hua'an received the order and immediately prepared to go on the expedition, the subordinate officers and men had not fought for five consecutive years, and the decline in actual combat experience was inevitable.

The main force marched to the south, and it was definitely not possible to take care of the tuntian in the south of the Yangtze River, so Hua'an transferred back 10,000 of the 20,000 horses in the tuntian in the north of the Yangtze River to take care of the fields and pastures in the south of the Yangtze River.

In fact, the 20,000 men and horses of Tuntian, after several years of training, have not much difference from the regular army, when the main force is about to march south, they also shouted to participate in the war, Hua'an refused to participate in the war on the grounds that Zhao looked at the Central Plains and left them to guard against Zhao's attack.

At this time, Hua An's childhood playmates Wang Wu and Wang Liu had been promoted to military masters, and seeing that Hua An and Wang San had gone on the expedition, they felt a little uncomfortable.

Seeing that the two were a little unhappy, Hua An gently patted them on the shoulder and asked, "What's wrong, I look unhappy." ”

"Big brother, we have been training and farming in the past few years, and we haven't fought a single battle, is this considered a soldier?"

"Yes! Finally, we had the opportunity to go on this expedition, but they didn't let us go. ”

Wang Wu and Wang Liu each complained.

Hua An smiled slightly and said, "What, I have been wronged, since you have entered the barracks, you are still afraid that there will be no chance of meritorious service." ”

"Big brother, when can we have this kind of opportunity!" Wang Wu hurriedly asked.

"Don't worry, train weekdays, there are five years at most, the Central Plains will be in chaos, when the time comes, I will go on a great expedition to the Central Plains, and there will be many opportunities for meritorious service!" Hua An once again spoke his prophecy.

"Five years, so long." Wang Liu muttered.

Seeing that the two seemed to be very anxious about the meritorious service, Hua An was a little displeased, paused, and said: "At most, it will be five years at most, maybe it won't take so long, and the eldest brother will lead the troops to the south this time, and the army of Zhao may go south at any time, you are stationed here, the eldest brother is more assured, remember, if the tens of thousands of troops of Zhao invade the south, you will block me a little, if the enemy is strong and difficult to resist, all the crops in the fields of Jiangbei will be burned, and the enemy must not be funded, let alone let the army of Zhao cross the river." ”

"Big brother, don't worry, with our two brothers here, the army of Zhao must not be able to cross south." The spirits of the two were finally lifted.

Seeing this, Hua An relieved himself.

In addition to the assembly and deployment of personnel, all kinds of materials, such as grain, grass, weapons, and camp tents, need to be prepared.

Fortunately, after five years of tuntian, the granary near the camp has already stocked 2 million deniers of military rations, and the grain and grass are naturally sufficient, and the materials such as camp tents and weapons are already available, and there is no shortage of them.

At the same time, during the few years that Hua'an was in Tuntian, he often thought about some issues of marching and fighting, and made corresponding adjustments to the training of soldiers and logistical support according to the experience accumulated in the previous expeditions.

Especially considering that in the future, the Northern Expedition to the Central Plains must be an expedition of laborers, and the requirements for logistics are extremely high.

For this reason, in recent years, there have been a lot of large and small baggage vehicles in the Northern Expeditionary Army camp in Hua'an, which are all made up by Hua'an and some carpenters, with different functions, with large transportation volume, good terrain adaptability, and fast speed, all kinds of baggage vehicles add up to tens of thousands of vehicles, these baggage vehicles can not only transport materials, but also transport combat soldiers, which can be described as powerful.

Hua'an originally planned to let the horses raised in the pasture to pull them, but the horses were trained in the direction of war horses, so that the future war horses were a great waste, and this would undoubtedly abolish the war horses, so that the war horses that could gallop on the battlefield became livestock that could only pull the carts.

The baggage cart is generally heavier, if it is pulled by manpower, the efficiency will be extremely low, since it is reluctant to use the horse, then it has to be replaced by a kind of livestock, the pasture of the Northern Expeditionary Army, the cattle and sheep are the most, and there are a lot of deer, but the deer is too precious, the size of the sheep is too small, and only the strong cattle are the first choice to pull the cart.

To this end, Hua'an ordered the soldiers to lead the adult cattle suitable for pulling carts in the pasture to the large camp, and put on various ropes to fix them in front of the baggage carts.

The character of the ox is undoubtedly docile, and after just a few days of adaptation, all the oxen are familiar with pulling carts, and there is no mania and aggressive behavior against soldiers.

The Northern Expeditionary Army sent more than 30,000 men and horses, but the configuration of war horses was only about 5,000, of which, Hua'an's personal battalion and the generals' personal guards occupied 2,000, and the remaining 3,000 war horses were all equipped with the cavalry army under the command of Thunderstorm, obviously, the cavalry of the Northern Expeditionary Army was somewhat insufficient.

And the lack of cavalry, when the battlefield is in an advantageous position, it will not be able to effectively pursue the enemy, and even miss the once-in-a-lifetime fighter plane.

For this reason, Hua'an decided to let all the three-year-old foals on the pasture be assigned to the army, and these six thousand foals have been trained to be relatively mature, although they are still very immature, but they are enough to go to the battlefield.

Hua'an decided to assign them all to the other two armies under Thunderstorm, so that the more than 10,000 soldiers and horses under Thunderstorm would all become cavalry, but fortunately, all the soldiers of the Northern Expeditionary Army were trained in riding in the camp, and there was no problem of zài training, and the infantry stepped on the war horse and immediately became qualified cavalry.

Jiaoguang Erzhou is far away in the direction of the South China Sea, the road is extremely long, this time to go to quell the rebellion, a back and forth at least a few months, although the local can also collect some grain and grass, but for the sake of safety, Hua'an decided to bring more than three months of rations, enough 30,000 denier, just to transport military rations used a full 3,000 medium baggage trucks, weapons, camp tents and other materials also used 3,000 vehicles, the remaining 4,000 baggage vehicles are used to transport 20,000 horseless infantry, an average of five soldiers per vehicle, this is naturally to speed up the march.

10,000 baggage trucks, in addition to the need for cattle to pull, but also need to drive people to operate, the 1,000 soldiers of the baggage battalion are good drivers, but there are 10,000 baggage trucks, manpower is far from enough.
