Historically, the Song army adopted Guo Yaoshi's suggestion and attacked Yanjing City successfully, but made two major mistakes in a row, resulting in the Liao army overturning, one is that Tong Guan ordered to kill the Khitan and Xi people in the city, which aroused the resistance of the soldiers and civilians in the city, and secondly, Liu Guangshi's reinforcements did not arrive in time, resulting in thousands of Song troops in the city fighting alone, and the whole army was wiped out after the Xiao Gan army returned to help.

Li Yanqing didn't know much about this history, but the background at this time was much the same as history, and it was reasonable to think of the strategy of sneaking up on the enemy's lair.

But whether the mistakes of the past will be repeated, the key lies in whether Li Yanqing can capture Yanjing City and whether the reinforcements can arrive in time.

The 10,000 troops led by Li Yanqing left the camp and headed south after an hour, but after ten miles to the south, he made a detour to the northwest and rushed to the north of Yanjing City in a roundabout way.

At the same time, the planter Daoliu Zongze led 10,000 troops to garrison the camp in Liangxiang County, and he personally led 50,000 troops to the direction of Wanping County, while Wang Yuan and Zhang Shuye, the deputy commander, led 10,000 left troops to the northeast, and they and Li Yanqing agreed that the time was to arrive at the east gate of Yanjing City at two watches.

At the first watch, Li Yanqing finally arrived outside the north gate of Yanjing City after a forced march of 80 miles, and the 10,000-strong army was temporarily hidden in a lush forest about two miles away from the city.

Xijin City is the name of the Liao State, and the Liao State also called it Nanjing, but the Great Song Dynasty had already officially renamed the city of Xijin to Yanjing City after the Song-Liao negotiations were over, and at the same time changed the name of Xijin Mansion to Yanjing Mansion.

This is the first time Li Yanqing has witnessed Yanjing City with his own eyes, in fact, he has already done his homework in Fanyang County, and he has a very thorough understanding of Yanjing City, but now that he has witnessed it with his own eyes, the magnificent and tall city wall still gave him a lot of shock.

Yanjing City is not like many small county towns are rammed with mud, but made of a piece of big bluestone, unusually strong and tall, the city head is as wide as two zhang and five feet, can be parallel to three ox carts, the circumference of the city is more than 40 miles, there is a moat as wide as two zhang outside, and a high suspension bridge is pulled up on the moat.

However, the various city gates are not exactly the same, and the reason why Li Yanqing chose the northern city is because the northern city wall is actually a part of the palace city wall, and it is not as tall and strong as the other three city walls.

Outside the north city is the forbidden garden of the emperor of Liao, composed of forests and grasslands within a radius of dozens of miles, and close to the north gate is the garrison of the army, but now the army has been dispatched, the military camp is an empty camp, but there are still nearly 100 people guarding the military camp.

In order not to startle the snake, Li Yanqing's army did not press on the whole line, but sent a small number of surprise soldiers to attack the North City Gate, and the burden of this sneak attack naturally fell on Yan Qing's shoulders.

As the Marquis of the scout camp, it is his bounden duty to capture the North City Gate.

．．．．．．．．．

As the main army of the Seed Master Road has moved north from Liangxiang County, Yanjing City has strengthened the city defense, and 8,000 of the 10,000 Liao soldiers stationed in Yanjing have been put into the city defense, of which the Imperial Forest Army defending the north city is as many as 3,000 people, and the 3,000 people are divided into three squads, patrolling the city day and night.

The north city gate is also called the Xuanwu gate, it is a thick gate made of iron sheet and giant wood, twelve iron door bolts, each weighing two hundred catties, every time the city gate is opened, the door bolt needs to be hung up from the city tower with a hinge, and the heavy city gate can defend against the impact of heavy siege rams.

On either side of the gate was a high gate, which was actually a large watchtower, each with twelve soldiers watching over the perimeter.

Not long after, a soldier rushed over and reported to Li Yanqingyu: "Qi Yu is in charge, for some reason, the city is brightly lit, there are at least 3,000 defenders patrolling it, and there are nearly 100 soldiers patrolling outside the city gate, and Yan Yuhou can't get close to the city gate." ”

Li Yanqing was stunned, what is going on? The information he got before was that there were only a few hundred people patrolling in Beicheng at night, which was relatively easy to control, but tonight's situation was completely opposite, could it be that the Liao army found something?

Li Yanqing chose to attack the Xuanwu Gate of the North City, a very important reason is that the Xuanwu Gate of the North City does not have a suspension bridge, but builds a stone bridge across the moat, and can directly control the palace by capturing the Xuanwu Gate.

He went north this time, and did not carry any siege weapons, only brought ten earth-shaking thunders, he wanted to use the earth-shaking thunder to blow up the city gate, and the north city gate without a drawbridge was the best siege point, but he encountered an unexpected situation.

"What time is it now?" Li Yanqing turned around and asked.

"It's just after one watch!" A soldier replied in the back.

The time that Li Yanqing and Wang Yuan agreed on was two watches, and Wang Yuan would come to support him at two watches, and it was still early.

At this time, Liu Jian whispered to Li Yanqing: "It's better to sneak attack the secondary door!" ”

Xuanwu Gate is the main gate of the north city, there are two auxiliary gates on the left and one right, the right gate is five miles away in the east, the left gate is five miles away in the west, the thickness of the city gate of the two auxiliary gates is much lower than the Xuanwu Gate, but it has a suspension bridge, and it is outside the palace city, unlike the Xuanwu Gate that can be directly killed into the palace.

Li Yanqing pondered for a moment and then said to the soldiers: "Go and inform Yan Qing, go to the east and sneak attack the right door!" ”

The reason for attacking the right gate in the east is because Wang Yuan's army will come from the east to respond, so the Song army must first take the east gate, Li Yanqing immediately ordered Yang Zaixing to lead 2,000 people to stay outside the Xuanwu Gate, once the palace is breached, Empress Dowager Xiao is very likely to abandon the city and flee, the possibility of taking the Xuanwu Gate is the greatest, Yang Zaixing can lead the army to ambush outside the city.

Li Yanqing personally led 8,000 people to move to Youyemen.

At present, the main general in the city is called Xiao Fengxian, he is the nephew of the Empress Dowager Xiao, and he is also the envoy of the Southern Privy Council of the Liao State, and the deputy supervisor of the army.

This information made Xiao Fengxian very frightened, the Jin soldiers actually appeared on the periphery of the capital, but Juyong Pass was still in the hands of the Liao army, there was only one possibility, that is, Lu Longsai in the east was lost, or Zhang Jue, the general who guarded Pingzhou, surrendered to the Jin State, and the Jin soldiers could go down from the southeast of Liao and go straight to Yanjing.

Xiao Fengxian didn't know how many Jin soldiers went south, he was afraid that the Jin soldiers would raid the city at night, so he ordered the whole army to go to the city to defend, but he didn't expect that by mistake, Li Yanqing's 10,000 troops happened to attack Yanjing City at night.

At the head of the city, Xiao Fengxian carried a sword at his waist, and looked at the dark woods outside the city with a solemn gaze, just now a soldier found that there were night birds flying in the woods in the distance, which made Xiao Fengxian extremely vigilant, and he realized that the golden soldiers were very likely to attack Yanjing City tonight.

At this time, a soldier rushed over, holding an arrow letter in his hand, "Qi Yu Metropolitan Prison, there is a letter from the golden cavalry under the city!" ”

"Jin Bing?"

Xiao Fengxian was stunned, Jin Bing actually sent him an arrow letter, he took the arrow letter, pulled the letter from the arrow, opened the letter, and there was only one line of words inside, 'There are 10,000 Song troops outside the northern city, and they will attack Xijin City at night!' ’

Xiao Fengxian was suddenly startled, there were actually 10,000 Song troops outside the city, could it be that the night birds flew away just now not the Jin soldiers, but the Song army?

"Immediately pass my order, all the troops go to the city to defend!"

Xiao Fengxian hurriedly issued an emergency defense order, 'Dang! While! While! The alarm bell rang in the head of the city, and it reverberated throughout the city.

At this time, Li Yanqing had moved to the outside of the Youye Gate, where the defenders were obviously much smaller, and there were no torches at the head of the city, which made the city pitch black, which was very conducive to the scouts' actions.

Li Yanqing saw from afar that Yan Qing and the other ten people had disappeared into the moat, and at this time, a rapid alarm bell suddenly sounded from the city, which made Li Yanqing secretly taken aback, obviously an abnormality had been found in the city, and all the sleeping soldiers would get up, which meant that they would face a hard battle.

But Li Yanqing wondered in his heart, what went wrong with them? It was discovered by the enemy, could it be that the reinforcements led by Wang Yuan went north and were discovered by the Liao army spies? It was just now that his army was in the woods that alarmed the night birds, and alerted the defenders of the city.

Could it be.......

Li Yanqing suddenly thought of what the marshal said to him before leaving, could it be that Jin Bing had already gone south?

At this moment, Zhang Bao rushed over and whispered to Li Yanqing: "Qi Yu is in charge, the scouts on the periphery have found a golden soldier. ”

This news did not surprise Li Yanqing, sure enough, it was Jin Bing, it seemed that Jin Bing really went south, he hurriedly asked, "How many people are there?" ”

"About three hundred people, all cavalry, just three miles outside the Xuanwu Gate, only one mile away from General Yang."

Three hundred people are just a sentry post, not the main force of the Jin soldiers, Li Yanqing relaxed slightly, and hurriedly asked, "Does General Yang know?" ”

"General Yang knows, he has sent scouts to monitor this cavalry."

Li Yanqing nodded, "I'll go and find out the news again." ”

Zhang Bao turned around and rushed away, and Liu Jian next to him whispered: "The situation seems to be a little bad!" ”

"Why do you say that?" Li Yanqing asked puzzled.

"The Jin soldiers and the Liao army have a common characteristic, the ratio of the outpost army and the rear army is generally 100 to 1, these 300 cavalry are obviously only outposts, then the Jin soldiers behind are likely to be 30,000 troops, indicating that the Jin soldiers are not far from Yanjing City."

Liu Kuang's worries were not unreasonable, they rushed north at the beginning, it was because the envoys of the Jin State informed the imperial court that they would also send troops to attack Yanjing City together, and the Son of Heaven Zhao Ji was afraid that the Jin soldiers would take the lead, so he changed his plan and ordered them to go north immediately.

And the reason why the seed master Dao adopted his own plan was also because the Jin soldiers had captured Pingzhou Lulongsai, and the army would go south at any time, so he made himself sure to break through Yanjing City tonight, but the outpost of the Jin soldiers also appeared outside the northern city, and for a while, the situation in Yanjing City suddenly became complicated.

Li Yanqing weighed the pros and cons, and finally took out an arrow and handed it to a personal soldier and said, "Quickly order General Yang to come and join us, and there is no need to ambush outside the city again!" ”

Li Yanqing didn't know how many Jin soldiers there were outside, he was worried that there were too few troops outside the city, and once there was a fierce battle with the Jin soldiers, he was afraid that Yang Zaixing's army would suffer a big loss.

The soldiers rushed away with the arrows, and at this moment, the head of the city of the right gate suddenly burst into flames, and the Liao army shouted, followed by countless arrows shooting towards the city, Li Yanqing immediately realized that Yan Qing and they had been discovered, and he immediately ordered: "The army presses up and releases arrows to the city!" ”
