As early as when Li Chengqian first deliberately wanted to attack Goguryeo, the Tang Dynasty was actively preparing for this battle.

Wherever high-quality seagoing ships can be produced in the north and south, warships and troop carriers are being actively built.

As an emerging shipbuilding center, Guangzhou is known for producing the most sturdy Guangzhou ships, mainly because of the good foundation laid by the Ping'an, which has become an important base for the construction of warships.

And there is the foundation left by Lin Sen, the shipyard next to Panyu Zhichong Mansion has never stopped, and new ships are constantly launched, but what is produced here is enough to form a large fleet.

As for the timber they need, it is mainly responded to by Sichuan**, where as long as the best timber such as golden silk nanmu is cut down, let these wood drift downstream along the current, until it goes to sea, and then slightly retracted, it can be sent to Guangzhou and other places more easily.

This is much more convenient than any land transportation, and if you just hire a water elephant to pull these big logs, the efficiency is far worse than drifting down the river.

As for the plan to let this side help build a big ship and directly go down the river to pay the battlefield, forget it, it's okay to engage in inland river ships, but sea ships are not very reassuring.

Dengzhou and Laizhou, because of the development of traditional sea vessels, can also provide a large number of transport ships.

When necessary, it is similar to that of Guangzhou, and some so-called civilian ships are requisitioned.

Anyway, behind these guys who can run the sea trade, there are more or less Tang nobles, and at such a time, don't let them contribute, let anyone contribute, this is all due righteousness.

Just like the Ping'an, Jixiang, and Ruyi, the three strongest warships, ran at the front, and after getting Lin Sen's message, they unloaded the spices, pulled the whole ship's grain and ran to Dengzhou, ready to do a big job.

The other ships that were also in the spice fleet were not far behind, including almost the entire fleet of the Feng family, all of them followed the Ping An to the north, and by the way, they were also full of food donated by many children of the Feng family, which could be regarded as a labor army.

Although Feng Ang passed away a few years ago, the mantle of the governor of Gaozhou was taken over by his eldest son Feng Zhiji, but his brothers did not deviate from Datang, but because of the common interests of spices, and there were more exchanges and communication with the north, the sense of belonging to Datang was further enhanced.

Is it a positive sign that we can respond so positively this time and take the initiative to provide food and grass?

Although food is almost the least valuable thing in Lingnan, it is after all a desire to serve the country.

In order to reduce the burden on the land route, especially for those people in Shandong and Hebei, too many troops will not be recruited.

Fortunately, Datang is really not short of food now, and there is plenty of grazing land, so transporting grain and grass will not be too much of a problem, and the pressure on the front-line soldiers and civilians will not be very great. At least there will be no escape, let alone deserters.

It's been a long time since I've seen a big battle, and it's rare to have such an opportunity to earn great feats, and all the sergeants are in a state of gearing up.

Most of the soldiers who can be selected are elites, and there are many auxiliaries who have brought their own things and volunteered to earn credit.

If it weren't for Li Chengqian's explicit order and restrictions, the only son in the family would not be able to go, those who have no wives and children would not be able to go, and so on, and the so-called auxiliary soldiers who voluntarily went would have been several times more than the regular soldiers.

Lin Sen's subordinates worked overtime to produce compressed rations, all of which were hoarded, waiting to deal with this big war.

The benefits of this thing can be said to have been tested by previous wars, and now it has become the standard in the army, only when this convenient, easy-to-eat and nutritious marching dry food is all eaten, the Tang army will use other grain and grass to supplement, which also greatly reduces the logistical pressure.

For the Tang Dynasty, which has had bumper harvests year after year, especially after the large-scale promotion of high-yield crops such as potatoes, grain and grass are really the least problematic, which is also one of the reasons why Li Chengqian made up his mind to conquer Goguryeo.

Although Li Chengqian longed for this Goguryeo War, he also knew that he was not the emperor who was killed in the battle like his son Li Shimin.

Li Shimin himself is a famous marshal, so he can drive the expedition in person, and if he, Li Chengqian, really runs to the battlefield in Liaodong, it will only add chaos to the entire army.

Rather than that, it's better to let those generals play.

Therefore, after arranging the governors and generals from all walks of life, and coming to the last oath meeting, Li Chengqian waited in Chang'an City to bring back the good news.

Of course, according to the habits formed over the years, it is also indispensable to find a group of bigwigs to perform military chess on the sand table, and first take into account as many difficulties as possible that may be faced.

This time it was Goguryeo, which was attacked, and in a certain sense, the country that had dragged down the former Sui Dynasty could not tolerate the fact that the lobby did not pay attention to it.

Even Li Jing, the old military god, was invited, of course, it was impossible to go to the battlefield in Liaodong, he was an old man who was too old, and that was for his life, so he just asked him to come out to help and staff together.

In the end, the commanders of all walks of life were also decided, and Li Ji, the new generation of military gods, was also recognized as a wise general, responsible for commanding the army of Liaodong Province. Niu Jinda is responsible for assisting from the side.

Take the overland route out of Lulongsai, cross the so-called Great Wall of Goguryeo, and enter the city of Liaodong.

His command also includes a lot of elite cavalry attached to the steppe peoples, including the recent emperor who is very trusted by the emperor He Li and his clansmen, of course, other Turks, Xi people, Khitan and other tribes have come with soldiers and horses to listen to the use.

Lin Sen and the soldiers and horses of the headquarters were also on this road, still acting as a vanguard general. It can be regarded as making a safflower double stick with Qi He Li.

As the commander of the Pyongyang Provincial Army, Yi Daozong, a famous general of the clan, commanded the army to set off by boat from Dengju and Laiju, and after crossing the strait, he attacked Goguryeo from the other direction.

Xue Wanche, a fierce general, as Li Daozong's deputy, assisted from the side.

And the pioneer general on this road is Su Dingfang, who was strongly recommended by Lin Sen to go out of the mountain. Xue Rengui, who has now become Li Chengqian's confidant, is also a similar role to him.

The commander of the navy army is also an old acquaintance of Lin Sen, who helped him wipe his ass twice, took over his stall, and liberated him from the complicated situation Liu Renliang.

In fact, it is not difficult to see that these two armies are both famous generals, with a super general, and a few outstanding generals of the younger generation as pioneers.

Such a lineup can be said to be thoughtful and complementary, and it is safe enough when it comes to a real battle.

Although it doesn't seem that the number of people is very large, there is a total of about 100,000 regular soldiers, of course, this does not include auxiliary soldiers, and those attached Hu soldiers, but the combat effectiveness is enough to guarantee.

How many people were used to fight the Turks back then, is it similar to this time?

Datang has always been accustomed to winning more with less, which is why it will have such a terrifying reputation.

Moreover, the number of troops that can be mobilized at a critical moment is several times that.

What's more, the current Datang is different from the original Datang, and there is also the secret weapon contributed by Lin Sen.
