Lanzhou has been the most important town of soldiers since ancient times, Gan and Ning. The hub of Qing and Xin. It is bordered by the Yellow River in the north, with mountains on three sides, and the terrain is very dangerous. This mountain and river is the key, the city is dangerous, condescending, easy to defend and difficult to attack. Surrounded by the wall of the city, the Gaolan mountain peaks tower, becoming the natural barrier of the ancient city. Cen Shen, a famous frontier poet who has lived in the west of the river in the Tang Dynasty, has a poem praising Lanzhou and its southern barrier Gaolan Mountain: "The ancient city is dangerous, the high-rise buildings are connected to Wuliang, the roots of the mountain are in the post road, and the river is flooded in the city wall." Do your best to take the most dangerous situation.

In the Anxi army's position south of Nanshan, Lanzhou, it is preparing for attack day and night. The commanders of the Anxi Army all understand that the Battle of Lanzhou will be a life-or-death battle. The remnants of the Qing army are dangerous on the Yellow River in the north. In the south, there are high mountains on the first line of Donggangpo, Gaolan Mountain, Shenjialing and Gouwa Mountain. There are also strong fortifications, and then there are enough ammunition to wait for work. They have to attack from the bottom of the mountain, take dozens of miles of mountain fortifications on this line, and clear the obstacles on the southern periphery of Lanzhou City, in order to attack Renlan. It is not easy for the ancient city of the state to destroy the nest of the remnants of the Qing army and open the road. To be honest, the fighters are really not sure whether they can capture the Nanshan position.

After Li Xiang observed the Nanshan position of the remnants of the Qing army with a telescope, the already serious look on his face became more cold.

Surrounded by mountains, the mountains are dancing like silver snakes. On the narrow basin, the frozen Mang Mang Yellow River runs from west to east. Lanzhou is located on the south bank. In the west of the city, there is an iron bridge built on the 33rd of Guangxu in the Qing Dynasty connecting the north and south sides, and the north bank leads to Qinghai and the Hexi Corridor.

The rapid flow of the Yellow River has been said since ancient times that there is no bridge in the Yellow River. Lanzhou is located on the plateau. The river section here has been crossed by boats and sheepskin rafts since ancient summer and autumn. In winter, the river is frozen and can only walk on ice, which is extremely inconvenient and dangerous. At that time, there was a folk song:

The Yellow River is harmful, and the Yellow River is dangerous;

Ling Hong can't be crossed, and the big water is difficult to sail:

Crossing the river is like the next day, crossing the river is like crossing the ghost gate!

It can be seen how difficult it was to cross the Yellow River at that time.

In Hongwuzhong, the Ming Dynasty, the pontoon bridge just built is made of 24 giant ships, which are maintained by two iron cables and four hemp cables. The boat is paved with wooden boards and is called the "first bridge of the Yellow River". However, this kind of pontoon bridge is a seasonal bridge. Because of the flooding of the Yellow River, it must be dismantled before the Yellow River freezes in November every year. In winter, people pass directly on the ice of the river, and many people drown when it thaws every year. The next year, the river ice melted and the pontoon bridge was rebuilt, which was not only very troublesome, but also demolished, built and demolished in a year, which cost a huge amount of money.

Until the 33rd year of Guangxu, the pontoon bridge was changed to an iron bridge at the suggestion of Peng Yingjia, the General Office of Foreign Affairs in Gansu Province and the sponsorship of Sheng Yun, the governor who implemented the new policy in Gansu Province. It was built by the German merchant Tailai Yangxing Kayousi. The American Manbaoben and the German Derot provided technical guidance, but the material transportation and construction were all undertaken by China. The steel, cement and other materials used to build the iron bridge are purchased from Germany and transported by sea to Tianjin, from the Beijing-Fengfeng Railway to Beijing Fengtai Railway Station, and then from the Beijing-Han Railway to Xinxiang, Henan Province. From Xinxiang to Xi'an, it was transported to Lanzhou by horse-drawn carriage in 36 batches.

There are four piers under the iron bridge, which are made of cement iron columns, and the pier is paved with stones. It is 233.33 meters long and 7 meters wide. In the end, it costs more than 300,000 taels of silver. The original name is "Lanzhou Yellow River Iron Bridge".

After the completion of the bridge, two large stone squares engraved with "Three Sides of Liji" and "Jiuqu Anlan" were built on both sides, with couplets:

There were thousands of waves in the sea; and the first bridge of the Yellow River.

The natural danger of Kang Qu goes straight into the Haishi building. There is no way; the river creeps open the picture book and the cloud ladder is like this.

This bridge was the only bridge of the Yellow River thousands of miles at that time, so it was of great military value.

If Lanzhou is controlled, the Nanshan Mountain in Lanzhou is a must-have position. From east to west, Nanshan is Shili Mountain, Doujia Mountain, Majia Mountain, Yingpanling in the southern Liang of Gaolan Mountain, Shenjialing and Gouwa Mountain. Among them, Shenjialing is the closest to the iron bridge and guards two south-to-south roads with Gouwa Mountain, which is considered to be the "Lanzhou key".

Li Xiang held up his telescope and looked at it silently, and everyone behind him was also silent.

Shili Mountain, Maga Mountain and Yingpanling all have permanent reinforced concrete bunkers built during the Zuo Zhongtang period and then continued to be built. The fortifications are solid. There are three or four wide and deep outer trenches on the periphery of the main position. There are dark forts and field fortifications between the trenches and are connected to traffic ditches. There are artificially cut cliffs ranging from six to nine meters on the waist of the mountain. In front of the position is densely covered with barbed wire and mines, as well as the so-called "rolling thunder", that is, the oil barrel full of explosives, which is also printed with the label of Mobil. These "rolling thunder" can be thrown down the attacking team along the hillside at any time. Shenjialing, Gouwa Mountain has no permanent reinforced concrete fortifications, but before the start of the war, three circular civil fortifications were also built by the Qing army. In particular, all mountain positions are connected to Lanzhou City at the foot of the mountain, which is extremely convenient for material supply.

Li wanted to put down the telescope and looked back to see that everyone was speechless about Lanzhou City with copper walls and iron walls. First of all, he broke the silence: "Although Lanzhou is easy to defend and difficult to attack because of the steep mountains and strong fortifications, things are not so simple. From a macro perspective, the mountains of Nanshan are arranged from the east to the west, but except for the Shili Mountain in the east, which is a horizontal "one" to the outside world, the other mountains are oval beams that are long in the north and south and short in the east and west. To keep these mountains, you must build an elliptical circular position on them. Not only is the front line magnified several times, but also the front Both left and right can be attacked. Objectively speaking, Lanzhou is neither easy to attack nor defend.

After saying that, Li wanted to wink at Tang Yuewan. She would deliberately twist the cylinder on her body and pull out the map and spread it on the ground.

Lin Tiechang pointed on the map and said, "Zhang Fengyi's part attacked Shili Mountain and Doujia Mountain, Zhang Yun Mountain attacked Majia Mountain, Gucheng Ling, Liu Jing Department attacked Ying Panling, Jing Bu Mu Department attacked Shenjialing, and Gouwa Mountain."

"Because the terrain of Shenjialing is higher than that of Gouwa Mountain, it is more conducive to controlling the situation after conquering." Jing Bumu said, "Therefore, our department takes Shen Jialing as the first choice."

Basically, because the Anxi army has the advantage in military strength, the deployment is very simple. The two armies of the revolutionary army are used to return to the strongest of the Qing army, and the rest of the troops are one division to the Qing army and one association. The troops are divided evenly, and the key points are not seen.

Zhang Fengyi pointed out: "The weight of the above mountain positions in the whole Lanzhou defense system of the Qing army is different. The main positions of the defense line are Majiashan and Shilishan on the east line, Yingpanling on the middle line, and Shenjialing and Gouwashan on the west line. The loss of any of them is equivalent to a big hole in the bottom of the bucket. The ancient city ridge and Doujiashan on the eastern line are only avant-garde positions, which cannot shake the whole defense line after losing. However, due to the topography, it is very difficult to directly attack Mount Maga and Shili Mountain on the eastern front. Among them, Shili Mountain can still be tried, while Majia Mountain can't be tried at all. Therefore, we have planned for a long time and decided to conquer the two avant-garde positions of Guchengling and Doujiashan first, and then attack the Majiashan and Shilishan positions along the mountain beams, and finally destroy the Qingma defense. Therefore, the ancient city ridge, Doujiashan position and the main position of Majia Mountain and Shili Mountain are actually in-depth.

Li wanted to hear it loudly and couldn't interrupt, so he said, "There is nothing wrong with this arrangement. That's what I did in the battle!" In my mind, I tried to recall an old movie called "Liberation of the Great Northwest" and added casually: "However, you can increase the containment attack on Shili Mountain."

"It's still Li Shuai's thoughtful." Lin Tiechang said with sincere admiration.

Li Xiang was slapped by such a flattery, and his desire was extremely inflated. He squatted on the edge of the map and his brain rotated rapidly. His thoughts became clearer and clearer. He talked about it and said, "Yingpanling is the southern beam of Gaolan Mountain. From south to north, the position is three battalions, two battalions, head camps, and finally reached the main peak of Gaolan Mountain. Similarly, due to the terrain relationship, the Anxi army is unlikely to directly attack the head camp and Gaolanshan positions. It can only attack in order according to the three battalions, the second battalions, the head camp and Gaolanshan positions step by step. In this way, on the attack route of the Anxi army, these positions in Camppanling also form an actual vertical relationship, so one The loss of the three battalions of the line cannot immediately shake the Qing army's defense line.

Li Xiang's finger pointed on the map and continued: "On the western line, Shenjialing and Gouwa Mountain are adjacent positions on the left and right, not a deep relationship between the front and back. The loss of one of the two positions means that the whole Qing army's defense line disintegrates. Therefore, only the attack on the positions of Shenjialing and Gouwa Mountain on the western line can have a decisive effect overnight. The Shilishan position on the eastern side also has this effect, but the terrain and the level of the defense's fortifications are very unfavorable to the Anxi army.

Lin Tie grew up, and his face became more and more solemn. He tried to prick up his ears to listen to Li's analysis, and he didn't dare to miss a word.

"From the attacking force, the Jingbu curtain department will not be considered to be stronger than Liu Jingbu, will it?" Li wanted to ask, "But what makes people feel the most "chicken ribs" is Liu Jingbu's attack on Yingpanling. With the most powerful Liu Jing's army, he went to attack Yingpanling and set up the entire Anxi Army Artillery Regiment. It was too wasteful.

Li Xiang's thinking is getting more and more logical: "Yingpanling is the southern beam of Gaolan Mountain. To attack the mountain from here, you have to attack the third battalions, then the second battalion, then the first battalion, and finally reach the main peak of Gaolan Mountain. Looking at the main peak of Gaolan Mountain from the urban area in the north of the mountain, its mountain is towering. It is the main peak of the mountains in Lanzhou. From the level of Lanzhou City, the vertical height of the main peak of Gaolan Mountain is about 550 meters. It is really good to go up and enjoy the scenery, but the military significance is doubtful.

If you stand on the Santai Pavilion in Gaolan Mountain and look at Lanzhou in the north, the road at the foot of the mountain is not as thick as half as a Lanzhou ramen. How many buildings can be stuffed into a bowl of beef-sized land on Lanzhou ramen? Although there is a winding road from Gaolan Mountain down to Lanzhou City or Tieqiao, you have to go west to the remnants of Gaolan Mountain. Only Fulongping, Longwei Mountain, which is across the Leitan River, from Hualin Mountain in the north of Shenjialing, only reaches the flat to Tieqiao or Lanzhou City. It is difficult to go down the mountain because of the steep mountain with firearms and food bombs. Therefore, even if you occupy Gaolan Mountain, you can't control the iron bridge with firepower. If you deploy troops to attack, you can't quickly enter the iron bridge and Lanzhou City. To make an extreme analogy, do we need to climb the Badaling Great Wall to attack Beijing?

Yingpanling is a reinforced concrete fortification built by the Qing army during the Zuo Zhongtang period. The mountain is steep and difficult to attack. If the third battalion is lost, there will be the second battalion, the head battalion and the main peak position of Gaolan Mountain, all of which are self-contained. The Yingpanling Qing army mainly adopts the tactic of relying on strong fortifications to kill the other party. In this way, the Qing army could invest little troops and little casualties, which gave the attackers a lot of casualties.

Look at the terrain of Shenjialing. Shenjialing and Gouwa Mountain on the west side not only occupy two highways from the south, but also Shenjialing is the closest to the Yellow River Iron Bridge in several main positions. The vertical height of Shenjialing is only about 70 or 80 meters, and it doesn't take much time to go up and down the mountain. Once occupied, it is much more convenient to attack the iron bridge or urban area than Gaolan Mountain.

Secondly, the Qing army fortifications in Shenjialing are civil fortifications temporarily built before the war, which are easy to be destroyed by artillery fire; the efficiency of artillery fire is high and the difficulty of attack is relatively low.

Third, the beam of Shenjialing Mountain is basically flat, and the effect of the Qing army's civil structure fortifications was greatly reduced after being bombarded by artillery fire. Therefore, as long as the People's Liberation Army attacks and stands on its feet, the defensive side's geographical advantage is not great. It can be said that there is no danger to defend. Therefore, the Anxi Army can then push forward more easily, and the Qing army lost this mountain. Liang is equivalent to collapse, so we should also strive to drive the Anxi army off the whole mountain beam to ensure the battle.

Fourth, the main positions of Majiashan and Shilishan on the eastern line include Guchengling and Doujiashan as avant-garde positions, and several positions in Yingpanling on the middle line are arranged in depth, so the loss of the front-line position cannot immediately shake the whole defense line. Although Shenjialing has a Gouwa Mountain position adjacent to each other, it is not a deep support, but a side-by-sided companion. The loss of one of the two positions means that the whole line of defense is disintegrated.

Li Xiang's saliva splashed everywhere and dissected the Lanzhou defense line. The disease was also found, but he didn't operate. Zhang Yunshan was so anxious that he asked, "Li Shuai, what should we do?"

"What should I do?" Li wanted to be stunned. Playing with his mouth has always been his strength. It is not his specialty to assign combat tasks. He has always provided only strategies, which are specifically implemented by the generals below. He coughed dryly: "Do you still want to ask me?" Don't you know the story of Tian Ji's horse racing?

Lin Tiechang said: "If the Anxi army really takes Shenjialing as the focus of the attack, it can use the seven regiments of Liu Jingbu to contain the Yingpanling, and assign two elite regiments to the well curtain department to attack Shenjialing and occupy Xiguan and Tieqiao along the Lan'aguan Road and Leitan River on its east side after conquering Shenjialing, and the artillery of the Anxi Army. The regiment also transferred one-third of the heavy artillery to join the Shenjialing battle. In this way, Shenjialing's battlefield conditions and superior artillery fire made the position become a grinding wheel for strangling and depleting Qing soldiers.

"Let's arrange it like this." Li wanted to stand up, looked at Lanzhou City, and said, "Don't be in a hurry to attack first. There should be four to five days to prepare for the attack... Now the situation is very unfavorable to us. The Qing Emperor has abdicated, Yuan Shikai sharpened his knife. Time is very tight... But let's remember that we can't reach the speed."
