Nowadays, most of the troops in the feudal towns in the Daheng Empire are organized by armies and divisions, and there are very few legions, even if there are, but they are just a name, such as the first legion, the second legion, and the third legion of Quyang Prefecture before.

To some extent, these legions are not pure troop legion numbers, but troop titles similar to those of the Daheng Unification Army.

If you really want to talk about the legion, now there are only the Guards Legion and the Black Sword Corps controlled by the Ji royal family in the Tang Empire.

The Guards Legion has a history of more than 300 years, but the Guards Legion has evolved to the present, and it is no longer a legion, but more like the Jingzhou Army, but it still retains the name of the Guards Legion.

The other is the Black Sword Corps, although it is called a corps, it is actually a corps-level unit.

As the starting force of the Sixth Dynasty of Daheng, the Black Sword Corps was the main force of the Ji Dynasty's external conquest and internal suppression for more than two hundred years.

The black whirlwind formed by the black sword cavalry riding the top Nanzhou war horse, wearing full body iron armor and wearing a black cloak, no one can stop it!

Even if it is dismounted and fighting on foot, the cavalry in the Black Sword Corps are also the top hoplites in the Cold Weapon Era!

But such a huge heavy cavalry is slowly declining!

The decline of the Black Sword Cavalry is not because of the civil strife in Daheng, but purely because of the changes of the times, which has led to the weakening of the role and cost performance of the heavy cavalry step by step.

As early as the Hengao War and the subsequent civil strife in the early days of Daheng, the cavalry of the Black Sword Corps had abandoned the full-body plate armor and evolved into cuirassiers, and now, although some cuirassier regiments are still retained, most of the cavalry of the Black Sword Corps are actually pure light cavalry.

Although it has the name of the corps, the actual scale is only more than 20,000 cavalry, and it is estimated that it will not be able to beat the First Cavalry Army of the Daheng Unification Army.

The famous black sword heavy cavalry has actually disappeared from history.

The Guards Legion and the Black Sword Legion are the most typical legion-level troops in the Sixth Dynasty of Daheng.

It is also the highest establishment of Daheng's traditional standing army, and this level of organization naturally cannot be set up indiscriminately, Lin Ziran needs to consider it carefully.

However, if it is only a temporary campaign headquarters, then this is much more arbitrary, and it will be automatically revoked after the fight anyway, so you don't have to worry about the follow-up problems.

It was against this background that the Jingzhou Campaign Headquarters was established.

After the establishment of the Jingzhou Campaign Headquarters, Lin Ziran did not have to go to the front line with high-level officials such as the General Staff Department in the previous Dongdingzhou Campaign, Zishengzhou Campaign, and Quyang Prefecture Campaign.

Last year, he was able to go to the front line to fight in person, because he didn't control much territory, and the troops were only two or three hundred thousand.

But now, there are six states under the direct control of the Daheng Unification Army, and the regular army under its command has more than 600,000 troops, and there are nearly 100,000 garrisons.

If you count the total number of troops, it is actually 700,000 people!

With such a huge territory and so many troops under his hands, he needs to stay in the rear to sit in the rear, coordinate the strategic deployment of the entire Daheng United Army, and handle many government affairs to maintain the war and finally complete the unification.

After the end of the Northern Expedition strategic meeting on the 15th, the war machine of the Daheng Unification Army had completely stepped on the accelerator and roared and launched the final charge!

On the 20th, Lin Ziran, who set out from Luohai City, took an inland river boat all the way, and then transferred to a train, arrived in Dongdingzhou in a low-key manner, but he did not go to the front line of the Mihe defense line, but in Ansu City, the railway hub in Dongdingzhou, which is also the city of Xinzhou in Dongdingzhou.

It is the second largest city in Dongdingzhou, and a few decades ago it was just an ordinary coastal city along the Baiquan River, but because the east-west railway and the north-south railway of Dongdingzhou intersect here, it has become a railway hub in Dongdingzhou, and then developed.

Last year, considering that the damage to the original state city of Dongdingzhou was relatively serious, and the transportation was not too good, some high-level officials in the marshal's palace and the state commanders and other high-ranking officials sent to Dongdingzhou applied to move the state city to Ansu City, the most important transportation hub in Dongdingzhou.

After Lin Ziran approved, this place became the Xinzhou City of Dongdingzhou!

After arriving in Ansu City, Lin Ziran did not make a big fuss, but met with the generals in a very low-key manner, and did not even interfere in the follow-up strategic arrangements of the Jingzhou Campaign.

The reason why he came to Ansu City was just to show his attitude, not to command the battle.

Now that the Daheng Unification Army has nearly 700,000 first-line troops and second-line troops, he can no longer directly go to the front line to command the battle on a certain front as before.

He's just here to inspect.

However, this still made the generals of the Daheng Unification Army on the front line of the Mihe defense line also feel great pressure.

Liang Chenglei, commander of the Jingzhou Campaign, Wu Dajiang, commander of the Third Army, Zuo Yikai, the new commander of the Fourth Army, and others all knew that Lin Ziran was watching from behind.

But this is their idea, and Lin Ziran himself is still just seeing people and handling ordinary official business at the same time.

Now everything that needs to be done has been done, and now all Lin Ziran needs to do is wait.

On May 25, Lin Ziran in Ansu City on this day seemed a little absent-minded.

Not only him, but even several other core senior generals who came with Lin Ziran also looked nervous, Wu Guanlin, Qiu Honglin, Duan Hongxiao and others.

What can make these people nervous and worried together is naturally because, according to the predetermined top-secret battle plan, if nothing else, the Battle of Jingzhou will officially start this morning.

But because of the distance, it was already noon, but in Ansu City, they still didn't know whether the troops on the front line had fought according to the predetermined plan.

While they were anxiously waiting, the sound of artillery was already rumbling in the Mihe defense line, and the sound of artillery on the Mihe defense line had not stopped since nine o'clock in the morning.

Beginning at 9 o'clock in the morning, when Liang Chenglei saw the First Artillery Fleet rising along the river in the lower reaches of the Mi River, he formally ordered the artillery units of the whole army to carry out intensive artillery bombardment of the beachhead defensive positions of the allied forces of Jingzhou, Gaoqingzhou, and Ningwuzhou on the north bank of the Mi River.

Subsequently, more than 20 river gunboats of the First Artillery Fleet arrived at the Uwa Ferry one after another, and joined the artillery bombardment operations one after another.

Participating in the front-line artillery is not only the field artillery units of each unit, but also two siege heavy artillery regiments and three 200-mm train guns specially reinforced!

Under the bombardment of the artillery of the Daheng Unified Army and the naval guns, the positions of the three-state coalition forces on the north bank were filled with smoke and dust, and the sound of explosions continued!
