These places were cold and not suitable for agricultural development, and the exploration ships were not lucky enough to find gold directly on the seashore, so the Empire's attitude towards these places was to settle for development and so on.

First erect a stone monument to confirm sovereignty.

Therefore, although the above-mentioned areas have not yet been a single Tang people, the Tang Empire has unceremoniously classified the above-mentioned areas as imperial territory, and the above-mentioned areas are all under the jurisdiction of Northeast Province!

Today, although the Northeast Province of the empire has only a few hundred thousand people, the territory under its jurisdiction is quite large, north of Liaodong and Liaoxi, all the way to all areas of the Arctic Ocean, whether it is the Heilongjiang region, the Outer Xing'an Mountains region, or the Kuwu Island, or the Kantan Peninsula, all of which are under the jurisdiction of the Northeast Province.

Well, although it is said that the Tang people have not been able to set foot in most of the above-mentioned areas, it is not important, the important thing is that these are the territory of the empire.

However, after the Northeast Campaign began, the navy found that it could also get involved, landing in Vladivostok first, then going north along the river, landing at the mouth of the Heilongjiang River, and then fighting in depth along the river.

The navy's plan is naturally not just as simple as landing at the mouth of the sea and then cruising around the inland river, the navy also has a deeper plan.

That is, by opening up the inland river routes in the northeast region, and then building cities along the river in Heilongjiang, and finally relying on Heilongjiang for supply and transportation, although at that time, the city and the navy have nothing to do, but if this is transported by river, then in the end it is necessary to go by sea, so that the importance of the navy is naturally more important.

To put it bluntly, the navy just wants to highlight its presence in this part of the northeast, and it can't let the army steal all the light, so it's a desperate toss.

However, this plan is still limited to the navy, and has not been disclosed to the public, and the army does not know about it.

This kind of thing cannot be distinguished by right or wrong, good or bad for the empire, the two sides are just competing for dominance and a sense of existence.

When Fang Xitong was tossing in the northeast, a large number of military supplies were also transported to the north one after another, not to mention the most basic materials such as food and ammunition, in order to resist the severe cold, the military also prepared a large number of cold materials, clothes, spirits and so on.

Although the Northeast Campaign is expected to be launched after the ice and snow have thawed, the main campaign should be conducted in summer and autumn, striving to end the large-scale campaign before the arrival of winter.

However, no one can say anything about the war, and if the war drags on on a large scale and drags on until winter, if a large amount of cold materials are not prepared in advance, then the trouble will be great.

Li Xuan didn't want to see his army stage the embarrassing situation when the German army marched into Russia.

Therefore, cold materials must be prepared in advance, and they must be very well prepared.

After the supplies were in place one after another, the Northeast Expeditionary Command also finalized the final battle plan in March, and the scheduled launch time of the campaign was in late April, and the specific time depended on the weather.

Because of the restrictions on distance and communication, it was initially set for the end of April, and the detailed time could be determined by the subordinate armies, and it was acceptable to advance it a few days or postpone it a few days.

According to the battle plan, the battle will break out in the Liaohetao area at the beginning, a large number of elite cavalry will maneuver to the predetermined position in advance, and then after the battle breaks out, the cavalry corps will quickly move north to intersperse, use the mobility of the cavalry to directly destroy the enemy's outpost defense, and then divide and outflank the enemy's tribes to avoid their contact and mobilization and assembly.

The infantry, on the other hand, is really just to follow up in the rear, deal with the remnants, and then build and maintain supply lines.

Yes, although the infantry units participating in the battle this time also have two main infantry divisions, the task of these two infantry divisions is still to maintain supply lines.

The main force of the battle will be cavalry-based!

In order to strengthen the combat effectiveness of the cavalry, the army provided the cavalry units participating in the battle with an excess of cavalry artillery in advance, although the cavalry artillery was also equipped in the past, but in the case of the Ninth Army fighting the Tatars, the cavalry units themselves were still insufficient, the number of cavalry artillery was insufficient, and their firepower was still insufficient.

Based on the combat experience of the Battle of Hetao, the army began to increase the number of cavalry artillery for cavalry units.

These cavalry guns are all lightweight artillery, mainly five-pound cavalry guns, and these five-pound cavalry guns, although they are restructured from the five-pound field guns in the artillery unit, but after lightweight improvement, the improved cavalry guns use more advanced steel, so although the cost is much higher, but in the case of ensuring the firing range and the life of the body, the weight is greatly reduced.

These cavalry cannons, if used, are enough to give the cavalry troops a lot of firepower!

After Fang Xitong finalized the final battle plan in Shenyang, he reported the relevant situation to Jinling, but this report did not mean that it was a request for approval.

In fact, when Fang Xitong set off at the beginning of the year, he had already obtained combat permission to launch a large-scale campaign in the spring and summer of this year.

If it is said that after the preparation is completed, it is necessary to ask for the approval of Jinling City before launching an attack, and it will take at least a month to come and go.

And in reality, it will not give Fang Xitong and the Tang Empire so much time.

So this time, Fang Xitong sent a letter to Jinling, just to report, telling Jinling that the Northeast Expeditionary Army was ready to start a formal operation in late April.

Time passed day by day, when this letter was delivered to Jinling City on April 14, Li Xuan read it, approved it, and then sent the secretary of the secretariat of the Hanlin Academy as an angel to the northeast armies, on behalf of the Son of Heaven to visit and comfort the troops participating in the war.

Just a few days after the angel set off, when the ship was still floating on the sea, on April 22, Fang Xitong, who was in charge of the Chinese army, officially issued an order for all departments to officially march.

Then he personally led the Chinese army into the Liaohetao.

The reason why only the Chinese army was brought was because the operational areas of the various armies in the northeast were relatively scattered, and according to the different locations of each department, their tasks were also different, and the direction of their advance was also different.

Fang Xitong has four armies and one Guards First Provisional Brigade under his command, of which there are about 100,000 main field troops preparing to participate in the battle, in addition to nearly 30,000 main forces and 20,000 reserve divisions, a total of about 50,000 troops are stationed in the rear, suppressing the rear, maintaining supply lines, and acting as strategic reserves.

The main force of 100,000 is also divided into three parts, the left flank is an infantry division and a cavalry division under the 14th Army, with a total strength of about 20,000 people, their main task is to seize the Daning area, and then continue to go north, cut off the route of the Mongolian left flank to flee westward, and at the same time cooperate with the main force of the Chinese army to encircle and suppress the Chahar and other enemies.

On the right flank were the mixed brigades and a reserve division under the 15th Army, with a total strength of 15,000 troops, whose main task was to seize the eastern regions such as Jianzhou and Shuangcheng.

And the Chinese army is the real main force!

Among the 50,000 elite cavalry, 45,000 cavalry are in the Chinese army, for this reason, Fang Xitong also specially set up the first cavalry corps, the second cavalry, and the third cavalry corps, three temporary cavalry corps, the first cavalry corps has 15,000 troops, the second cavalry corps has 15,000 troops, and the third cavalry corps has 10,000 troops.

If the cavalry corps were not set up separately, it would really be difficult for Fang Xitong to directly command so many cavalry troops, there were four cavalry divisions alone, and nearly ten independent cavalry regiments.

The infantry unit has one infantry division and two mixed brigades (including the 1st Guards Provisional Brigade), totaling 30,000 men.

This time, because the troops participating in the war all belong to four different armies, and the army-level command organization of Datang is an institution that belongs to a similar theater of operations, not a pure field army command organization, so this time, Fang Xitong adopted the method of the left wing, the right wing, the middle army, and the cavalry corps to command the troops, rather than commanding the army and then commanding the division.

This is also an important measure for the Datang Army to continue to explore the command system of the theater and field army, if nothing else, I am afraid that after the Northeast Campaign, the army-level command organization will become a pure field army, rather than the current theater command organization.

However, although there is a distinction between the left wing and the right wing, the commanders of these troops are still dominated by the original commanders of the armies, such as the left wing corps, whose commander is the commander of the 14th Army, and the commander of the right wing corps is the commander of the 15th Army.

As for the Chinese army, although the army is personally commanded by Fang Xitong, the commander of the infantry and artillery regiment of the Chinese army, which is composed of infantry and artillery units, is served by the commander of the Sixth Army, and the commander of the Tenth Army is to stay in the rear to serve as the commander of the strategic reserve, and to establish and maintain supply lines for the front-line army.

The four army commanders, none of them were pulled down, all of them were also corps commanders!

In addition, it is worth noting that among the commanders of the three cavalry corps this time, the commander of the first cavalry corps is Kang Changning, who made contributions in the Battle of Hetao!

This cavalry veteran, in the Battle of Hetao, resisted the Tatar cavalry head-on several times without falling behind, and even won more with less, making great contributions to the victory of the Battle of Hetao.

After the war, he led the cavalry troops to fight against the Tatars many times, and finally these achievements earned him the title of Imperial Viscount, and at the same time he was promoted to lieutenant general of the army, served as deputy commander of cavalry, and in the name of deputy director, continued to preside over cavalry training and combat affairs in the Hetao area.

This person can be regarded as a rare late-blooming general in the Tang Army.
