The castle walls of Seoul were not only numerous, but also varied, and rolling wood and stone were indispensable, and 100 tanks were also brought to equip the navy for naval warfare. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

It takes 20 people to operate, and can fire seven arrows at a time, among them, the arrow alone is seven inches long, five inches wide, enough to be as thick as an adult's small arm, with iron leaves as the arrow feather, a three-foot long big arrow, and 20 winch crossbows with six small arrows, and the longest range can reach 700 steps (about one kilometer today).

The large iron arrows fired from the winch crossbow were devastating against the enemy's siege towers, and the arrows fired in one volley destroyed all the fortresses and the towers fell upside down.

There are also 30 heavy trebuchets deployed in the city wall, the largest of which can project 70 pounds of boulders, which is a necessary weapon for the Tang army to attack and defend the city. Li Yu took them mainly to destroy the city when attacking the Silla fortress after annihilating the main side of the Silla army, and it could also be used to attack the siege troops of the Silla army at this time.

After inspecting it, Li Yu was very satisfied with the defense of Seoul, and when he was about to return to the palace arranged in the city, he turned around and asked: "Can Li Shangdan and Liu Shijiang withstand the attack of the Silla South Route Army?" ”

Xue Jun replied: "Your Highness, judging from the recent reports of Li Shangdan and Liu Shijiang, the Silla army attacked the valley guarded by Li Shangdan for three consecutive days, with thousands of casualties, and Li Shangdan's troops did not suffer too many casualties. The valley guarded by Liu Shijiang was dangerously narrow, and the Silla army did not reappear after a tentative attack. ”

"It seems that the Northern Silla Route Army has become a lone army that has penetrated deep into our territory."

However, His Royal Highness, Li Shangdan said that the Silla South Route Army sent several sentry cavalry deep into the Jaeyong Plain, most likely to get in touch with the Silla North Route Army. Once the two are connected, the Silla Southern Route Army may abandon the attack on Baekhuwei and venture through the valley to Seoul to join the Northern Route Army. ”

The camp of the White Tiger Guard led by Li Shangdan was installed on the slopes of the valley, which actually did not prevent the Silla army from forcing through. As Li Shangdan played, if the Silla Southern Route Army no longer considered the safety of the rear road and gave up attacking the camp of Baihuwei and ventured into the Zaunyeong Plain, it would also be a trouble for the Tang Army.

With the convergence of the northern and southern armies of Silla, the strength of the army will increase to 70,000, and the strength will undoubtedly rise to a higher level, which Li Yu does not want to see.

The current situation map of the Tang and Xin armies around the Zaining Plain was presented in Li Yu's mind, and Li Yu pondered it for a while and decided to install an insurance policy on the South Road.

With Chen Xuan as the head of the Zaining march and Qi Biguang as the deputy head of the army, he led the Kun Pengwei and Dangdi armies south to reinforce Li and Liu. If you can, you will annihilate the Silla South Route Army, and if you can't, you must block it in the valley and not enter. ”

Chen Xuan and Qi Biguang stood up and surrendered, and due to the southward transfer of the Second Army, Li Yu immediately made certain adjustments to the defense of Seoul City.

When Heiya Changzhi returned to Seoul with the victorious army, Li Yu summoned him, Qin Jingqian, and Li Wenbai into the palace overnight to arrange follow-up combat friendship.

Hei Zhi Changzhi had a slight idea about Li Yu's proposal to order him to lead the Beihae Iron Cavalry to Seoul and go around to the rear of the Silla army to cut off the other party's grain route. He put forward his new operational opinions from his investigation of the terrain along the way during this expedition.

That is, he led the Beihai Iron Cavalry to ride on the mountain range twelve miles southeast of Seoul, leaning on the mountain and backing the water to set up camp, and the horns of the city between him and Seoul, and the Silla army under the city of Dun was clamped. This move is conducive to the calm adjustment of its forces to deal with possible emergencies and realize the mutual reinforcement between Seoul and the Beihai Iron Cavalry Camp. It can also send troops to cut off the food route of the Silla army at a critical moment, and it can also form a deterrent to the Silla army under the city, making it difficult for it to relax and attack the city.

Li Yu felt that it made sense, so he ordered Hei Zhi Changzhi to do what he wanted, and he led the army to defend the city for a few days.

……

After the defeat of the righteous officials, they successively collected more than 1,200 defeated troops in Long, most of which were cavalry led by themselves. After joining up with Jin Yuanshu's main force, the righteous officer came to report the defeat of the advance and the killing of his ministers in frustration.

The initial battle was unfavorable, and the generals of the Silla army in the tent were all cast a shadow on their heads, lingering.

Jin Yuanshu stared at the righteous officer kneeling on the ground with a gloomy face for a long time without saying a word, and only after a long time asked in a tone full of anger: "There are 3,000 cavalry under your command, how many have you brought back?" ”

"The last general......" The righteous official glanced up at Jin Yuanshu worriedly, lowered his head and replied with a bitter mouth: "There are still one thousand and thirty-five horses left." ”

"I have no horseland in Silla, and the number of cavalry I have is extremely limited, and you lost forty percent of our army's cavalry in one battle, which is really good, good!"

Jin Yuan was extremely angry, and he scolded the righteous officer who was kneeling on the ground, and waved his army of 80,000 to the north with great ambition, but the vanguard was defeated in an encounter, which undoubtedly dealt a big blow to the morale of the army.

In anger, Jin Yuanshu asked the righteous official to be dragged out to punish the fifty military sticks, and then ordered him to lead the remnants to wait for the crime.

Listening to the thumping of the military stick of the righteous officer outside the tent, as the more and more fights, the righteous officer couldn't help but scream, and the generals in the tent gradually lost their hearts about the victory or defeat of the Tang attack.

"General Jin, the Tang army is brave and good at fighting, and the cavalry is a thunderbolt, and the ministers and righteous officials are facing a sudden attack by nearly 10,000 Tang cavalry, and the defeat is desirable......"

"Now, our army is not in a good position for the first battle, can we retreat to Duogu City first and fight again in the next day?"

……

Several generals who had already disagreed with Jin Yuanshu's plan to fight in the Tang Realm took the opportunity to propose to withdraw their troops first and repair their troops and horses.

When Jin Yuanshu heard this, he was suddenly unhappy in his heart, glared at them, and emphasized in an undeniable tone, "Our army has been ordered by the king to go on this expedition, and the southeast coastal area is still difficult to clear under the wanton raid of Tang Kou. The king pinned his hopes on us, defeating the Tang people and taking the old land of Goguryeo in order to relieve our country's border troubles and the people to live and work in peace and contentment. When the vanguard is defeated, our army will retreat? What kind of face do we have to go back to Jincheng to meet the king? ”

It's because you don't have the face to go back and meet the king! Several generals thought indignantly in their hearts.

"The whole army immediately marched towards Seoul, I was going to see if the Tang army had three heads and six arms, and could stop my 50,000 army?"

Regardless of whether they wanted to or not, the Silla generals returned to their camps under the order of Kim Wonshu and led the army to speed up.

Two days later, Silla's main force of 50,000 troops approached Seoul, and Li Yu received a report from the sentry cavalry and led a group of civil and military officers to climb the castle tower to watch.

I saw that a few miles away from the castle tower, wearing a spired iron helmet and gray battle robes, only a few elite troops wearing iron armor Silla army slowly approached.

The Silla cavalry was flanked by the infantry, and there were about five or six thousand horsemen.

Li Yu picked up the binoculars and watched, most of the Silla cavalry were wearing leather armor, and the iron armor seemed to be only available to officers.
