As the saying goes, it is difficult to go to the blue sky on the Shu Road, and the passage from Daba Mountain to Hanzhong alone is very dangerous. Fortunately, the Northern Expeditionary Army has effectively controlled the Jinniu Road, Micang Road, and Lychee Road from Daba Mountain to Hanzhong to Guanzhong in the past year. After Leng Yifei captured Sichuan, he immediately sent troops to control Bashan Shu Road. After extensive repairs, it was relatively easy for the army to enter Hanzhong.

Due to more than a year of preparation and repair, the Bashan Shu Road caused little difficulty to the Northern Expeditionary Army, but the next passage through the Qinling Mountains was placed in front of the Northern Expeditionary Army, and the key to the troops leaving the Qinling Mountains was the difficult road. The left column led by He Meng went straight to Baoji along the Hanshui to Fengxian County, taking the traditional official road, which was spacious and far away. This line is known as Chencang Road in history. When the Three Kingdoms competed for power, Shu sent troops to "Ming Xiu Plank Road to secretly cross Chencang" refers to this route.

Historically, there were 4 passages from Guanzhong to Hanzhong through the Qinling Mountains, namely Chencang Road, Meridian Road, Bao Shute Road, and Tang Luo Road. Before the Northern Expeditionary Army sent troops, after careful study, considering that the north exit of Baochuan Road and Fu Luo Road was close to Baoji and the location was westerly, these two routes were not considered. Then the only option for the army on the right is the Meridian Road.

The northern exit of the Meridian Road was in Chang'an County, southeast of Xi'an, which was very beneficial for the Northern Expeditionary Army to quickly outflank Xi'an. If the Northern Expeditionary Army appears in Chang'an County, if the Russian army chooses to flee, the Northern Expeditionary Army can quickly divide its troops to block the Russian army in Weinan. However, this route is very difficult to walk, especially if heavy equipment wants to pass through this ancient post road, the difficulty can be imagined.

Rice cang Road, Meridian Road, which runs through Bashan and Qinling, is called Lychee Road after the Tang Dynasty, and the fresh lychees that paid tribute to the Tang Dynasty Imperial Palace are the route that they take, and they can go directly to Chang'an in three days from Sichuan by fast horse. This section of Lychee Road Bashan is called Micang Road, and this section of Qinling is called Meridian Road. In order to meet the smooth passage of the army and the needs of future supplies, the Corps Headquarters specially set up an engineering regiment.

On this day, Leng Yifei led the corps headquarters and artillery units to the noon mouth of Yangxian County, and learned that He Meng had occupied Hanzhong and led his troops to the west, and his heart was overjoyed. Leng Yifei decided to rest for a day at noon and study the plan for crossing the Qinling Mountains. "Report to the commander, the forward troops have reported that they have occupied Shiquan, Ningshan, and Foping. The first part of the forward unit is marching towards Ankang! "Chief of Staff Khalid walked in.

Leng Yifei said in the big tent of the Chinese army: "Chief of Staff, health is not always necessary, now we have to study how to cross the meridian road of the Qinling Mountains and quickly occupy Chang'an County." How to hide and not be discovered is particularly important, the Qing army must be guarding along the way, and it is not difficult to seize the pass, the difficulty lies in how to prevent the Qing army from passing the news to Xi'an. Now, I would like to ask the operational staff officer to introduce the situation."

An operational staff officer walked to the map and said: "Commander, chief of staff, according to the information we have, the Qing army has garrisoned troops at the five steep passes on the Meridian Road, namely Shiyang Pass, Jialing Pass, Gaoguan Pass, Waist Ridge Pass, and Wugu Pass. If we take Wugu Pass head-on, the fleeing Qing army will soon pass the news on to the next pass, which means that the enemy army in Xi'an knows the news of our advance. Our staff office believes that we should form a sneak attack force to pass through the first four passes to take Shiyang Pass, and we must also eat all the Qing troops in Shiyang Pass to prevent news leakage. The Qing army did not have many troops to defend the passes, about 300 troops per pass. ”

Khalid said: "It seems that the governor of Shaanxi and Gansu is a straw bale, if he deploys heavy troops at the five passes, we will be in trouble." Now that Lin Xiong's troops have occupied Ningshan, I suggest that he form an assault force and take Shiyang Pass within 10 days, and not a single Qing soldier must be missed. "Okay, I agree with your suggestion, and immediately instruct Lin Xiong to form an assault force and take Shiyang Pass in a roundabout way. In addition, Lin Xiongbu was ordered not to alarm the defending Qing army after taking Shiyang Pass, and quickly seize Chang'an County, so as to create conditions for our army to deploy its troops. ”

In the mountains and mountains, the troops have been moving forward in secret. There was no road at all ahead, and the troops were marching with difficulty. Lin Xiong received an order from the corps headquarters and immediately selected 1,000 outstanding soldiers in the whole division, and led by a regiment commander to form an assault force. The regimental commander was about twenty-five or sixteen years old, and was talking to his guide on the way.

"Big brother! The mountains are high and the forests are dense, there is no way to find it, and there is not even a sheep intestine path, can we pass it? "The head of the regiment has no bottom in his heart." Sir, the grass people have been collecting medicine and hunting for decades in a radius of hundreds of miles, and every grass and tree here is familiar with it with your eyes closed, so you can rest assured. "A man with a small figure swears. As he spoke, a cliff appeared in front of him, and from a distance, the cliff showed an aura, as if countless monks were meditating in different forms.

"Report to the head of the regiment, there is a cliff ahead!" A company commander came down from the front to give a report. "Sir, there is a Thousand Buddha Cliff in front, and after crossing the Thousand Buddha Cliff, we have passed the first pass." After a while, the troops gathered in front of the cliff, and the regiment commander waved his hand, and more than a dozen soldiers with poor stature stood out in the queue, each carrying a large rope on his back, obviously these soldiers were good climbers.

"Sir, it's very difficult to climb with bare hands, I'm afraid I can't carry a big rope on my back!" The guide exclaimed. "Big brother! Rest assured! My soldiers are specially trained and there are no problems. The guide was still skeptical, and with a wave of his hand, a dozen soldiers began to climb with agility. The guide's eyes lit up when he saw their skillful movements, and he took the lead in climbing.

Two hours later, the regiment commander climbed up the rope. "Sir, the Northern Expeditionary Army is too powerful. To tell you the truth, few of the local residents can climb from the Thousand Buddha Cliffs, and the soldiers of your army are extraordinary. The guide gave a thumbs up. The head of the regiment said with a smile: "They used to live in the mountains, and they are all good climbers. After joining the Northern Expeditionary Army, he went through rigorous training, so naturally there was no problem. ”

A few days later, the troops came out of a deep forest, and a tallest mountain appeared in front of them. "Sir, there is the Waist Ridge Pass ahead, and we must climb over this mountain." Guided by. The regiment commander looked at the ragged soldier and said, "Brothers, we have been out for five days. I know you're very happy. However, the army behind us is watching us, and the commander is waiting for our news, we must take Wuyang Pass within 10 days and complete the task assigned to us by the corps headquarters. Brothers, go! ”

The troops finally reached the top of the mountain, although it was a hot summer, and the cold wind was blowing on the top of the mountain. The soldiers looked at the mountains and the rain and mist without the slightest chill. "Sir, that valley on the left is Beewaist Ridge!" Guided by. The head of the regiment took a telescope in his hand and carefully observed it, and said, "Brothers, we have conquered the highest mountain, and we have left behind us at the Beewaist Ridge Pass. ”

The troops crossed the Kidnapping Cliff, then crossed the meridian pass, and reached the northern part of the Wuyangkou at Zuihou Yiguan. Eight days had passed, all the soldiers' costumes were in tatters, everyone's faces were pitch black, and one mouth showed snow-white teeth. That afternoon, in a forest on the left side of Wuyang Pass, most of the soldiers were asleep, and the regiment commander called a meeting of his subordinates.

"Regiment commander, according to the investigation of the reconnaissance team, there are more than 400 Qing troops stationed in Wuyangguan, and the Qing army's defense is very lax, and there is no problem in taking it in one fell swoop." A company commander reports. The regiment commander said decisively: "I decided to act at dusk!" Immediately release carrier pigeons and report to the Corps headquarters. A few minutes later, two carrier pigeons spread their wings and flew into the sky and disappeared into the southern sky.

The carrier pigeon was provided by the Ningshan intelligence organization, and the corps headquarters has now arrived in Ningshan. At dusk, the commando of the Northern Expeditionary Army launched an operation, and the battle to seize Wuyang Pass was thrilling, and the defending Qing soldiers did not expect the Northern Expeditionary Army to suddenly appear from behind, and the battle was negligible, and 400 Qing soldiers became prisoners in a daze, and none of them missed the net, and Wuyang Pass was successfully occupied.

At dusk that day, the headquarters of the Ningshan Town Corps, Chief of Staff Khalid walked in and said: "Commander, after receiving the news of the carrier pigeon, the commando team successfully controlled Wuyang Pass. "Good! Immediately ordered Lin Xiong to attack and advance. , quickly occupying Chang'an County. Chief of Staff of Kazakhstan, after Lin Xiong occupied Chang'an County, our whereabouts were exposed. Take advantage of the fact that the Russian army does not react, and you will lead the 42nd and 43rd divisions to follow up. After Lin Xiong took Chang'an County, you led your troops not to stay in Chang'an County, and the soldiers and nobles quickly inserted themselves directly into Weinan, completely blocking the route of the Russian army's eastward escape. "Yes! Resolutely complete the mission! Khalid saluted and turned away.

The Northern Expeditionary Army captured the pass and beheaded the generals, and the Qing army fled. As judged in advance, the Qing troops at the various passes had no intention of resisting at all, but fled when they heard the news. Where did the Qing soldiers think that they would obediently become prisoners when they fled to Wuyang Pass. After the 5th, Lin Xiong led the 44th Division to Wuyangguan to make peace with the assault troops, and then quickly launched an attack on Chang'an County.

There are 5,000 Qing troops in Chang'an County, and these 5,000 Qing troops are not only stationed in Chang'an County, but also responsible for supporting the guards of various passes. The Qing army in Chang'an County was not prepared at all, and hurriedly organized resistance to a large number of Northern Expeditionary Army troops in the county seat. However, in the face of the encirclement of the Northern Expeditionary Army, the Qing army, which resisted for several hours, soon abandoned the county seat and fled to Xi'an.

After the Northern Expeditionary Army occupied the county seat of Chang'an, it did not pursue the Qing army. Outside Chang'an County, a large number of Northern Expeditionary Army arrived one after another. At this time, Lin Xiong, the commander of the 44th Division, stood outside the city gate to welcome the arrival of Chief of Staff Khalid. The subsequent Northern Expeditionary Army did not enter the county seat, nor did it stop, but continued to advance in the northeast.

Khalid and his entourage jumped off their horses, "Report to the Chief of Staff, your subordinates are here to greet you!" Lin Xiong saluted. Khalid replied, "Senior Commander Lin, I won't stay here. We captured the county seat of Chang'an, and the Russian army in Xi'an will soon understand the situation. In order to prevent the Russian army from escaping, I led the 42nd and 43rd divisions to quickly take Weinan and completely block the eastward escape of the Russian army. ”

Khalid continued: "There have been several heavy rains in a row, the roads are difficult to travel, and Commander Leng led the artillery unit and a large number of light and heavy troops, but they cannot arrive as scheduled, and it is estimated that it will take 10 days to reach Chang'an County." Your ministry is responsible for guarding the direction of Chang'an, and there must be no mistakes. "It's a subordinate who obeys the order!" Khalid did not enter the county seat, but kept going, whistling towards Weinan in the northeast.
