Chapter 203 Strategic Intent (II)

The main reason why Zhang Xuewu gave up the outer positions in Nanjing and changed to large-scale mine laying was that he needed to concentrate his troops to guard the fortresses such as Wulong Mountain, Zijin Mountain, Qinhuai River, Yuhuatai, and General Mountain in Nanjing to provide key points to support, so that his armored troops of the temporary First Mechanized Division would have the opportunity to continuously implement short-term counterattacks between key points. In addition, each division in Nanjing has a different size of artillery groups, and there are also firepower and support from the Yanziji Fortress and the 10th Heavy Artillery Regiment, Zijin Mountain Wave Group, Yuhuatai Cannon Group and the two heavy artillery brigades in Jiangbei.

With enough manpower, Zhang Xuewu used a large amount of manpower to cooperate with the garrison troops to demolish and destroy the city. As long as it was needed by Zhang Xuewu, no matter where it was or what cultural relics were, he would be demolished for me. The embankment along the Qinhuai River was raised and widened, and the firepower points on the reverse slope were built, combined with anti-tank trenches of six meters wide and six or seven meters deep. These excavated earth and stones were combined with a large number of blue bricks and stone slabs, as well as all wood were built V-shaped trenches and closed double-enclosed trenches.

Because the groundwater level in Nanjing is extremely high, water seepage begins after two meters of excavation. Therefore, there is not only the seepage of water in the anti-tank trenches, but also a large amount of silt. The key is that the Japanese army could not see this anti-tank trenches on the other side of the river embankment. They will only discover them if they attack the river embankment on the other side. Moreover, all the bridges on the Qinhuai River were blown up in a planned manner. For the locations where the floating bridges might be built, there are gun groups to mark the firepower of the secret space.

Zhang Xuewu's strategy of defending Nanjing actually originated entirely from the Battle of Stalingrad in history. It was with the Volga River that the Soviet army could continuously transport materials and soldiers. Moreover, the Soviet artillery group on the other side of the Volga River was also the top priority for turning the tide. However, compared with Stalingrad, there was not much to compare with in the Battle of Nanjing. It can only be said that at a critical moment, the Chinese people still need to block the Japanese pirates with their flesh and blood and fight for time with the Great Wall of flesh and blood! At least he needs to persist for two months. At that time, the main force organized in the rear will be bound by the troops, and the Japanese army attacking Nanjing will naturally retreat without fighting.

Moreover, Zhang Xuewu did not think that the *** people could last for two months under the city of Nanjing. The troops mobilized by the *** side this time had more than 60 divisions. For this reason, the entire *** Empire was squandering food. If the materials plundered from North Korea, Taiwan, and Northeast China were not as a guarantee, I am afraid that Emperor Hirohito's concubine would have to go out to communicate.

*** The man is like a small horse pulling a big cart. It was very rapid at the beginning, but lacked endurance. *** The army basically used horse-drawn as its main means of transport. There is no need to talk about mechanization, and even motorcycles are far away from Shanxi!

Therefore, in terms of strategic mobility, the Japanese army and the Chinese team are almost the same. Therefore, it is very difficult for both the *** army or the Chinese team to implement a strategic encirclement of the other party, and it is even more difficult to annihilate the opponent's main force.

On the Yanziji Fort, Zhang Xuewu met Peng Mengji, the commander of the 10th Artillery Regiment, a very inconspicuous figure, wearing a white shirt that was soaked and almost invisible, with blood seeping on his shoulders?

After asking, Zhang Xuewu learned that there was a giant shore defense cannon that was removed from the Wusongkou Fort in Songhu, which was about to be installed on the cannon mount of the new fort in Yanziji. Zhang Xuewu was shocked when he saw the giant cannon dragged up to the top of the mountain with ten winches and more than a thousand people shouting horns!

The Krebi shore defense gun made by Krupp during the Second Prussian Empire has a tube of 32 times, a diameter of 280 mm, a total weight of 46 tons, a maximum elevation angle of 30 degrees, an effective range of 20,000 meters, and a 270 kilogram armor-piercing shell can penetrate 65 cm thick homogeneous steel plates within 3,000 meters, and its maximum firing rate can fire 1.5 shells per minute.

This big guy is a magical weapon! The maximum tonnage of Japanese destroyers entering the main stream of the Yangtze River is not more than 3,000 tons, generally between 1,200 tons and 1,700 tons. The artillery is a double-barrel 150 mm naval gun in the front turret, a single-barrel 150 mm naval gun in the rear turret, and a 105 mm open gun position or a 75 mm closed gun position on the side. The high-bridge command tower is equipped with armor protection.

For such destroyers, the Krebi shore defense cannon made by Krupp is a huge killer weapon, just like smashing a small wooden ship with a trench. If a daily destroyer of more than 1,000 tons is like a high-explosive bomb, it will probably lose most of its combat effectiveness. If it is hit by two to five, the entire ship will probably be flattened and sunk.

The most important thing is that Yanziji is located outside the maximum elevation angle of the naval gun, which means that the Japanese naval gun cannot hit Yanziji turret. If it exits the elevation range, it will be within the direct firing range of the artillery artillery. If it retreats, it will have to exit its own naval gun range. Therefore, the most concerned Krebi shore defense cannon made by Krupp is the air defense issue.

Zhang Xuewu was the first to take off his shirt and directly joined the team of pulling ropes. The generals on the side were stunned. This 25th garrison commander! I didn’t think about it before I did anything. You rank rank commander of the first rank of garrison commanders. In name, all of you belong to you. Who is still standing?

Did he come to inspect? Or did he come to work hard? With the addition of a large group of generals, the officers and soldiers burst out with greater strength than before. The more than 40 tons of Krupp's Krebi shore defense gun made by Krupp, even after dismantling, the final barrel was more than 11 tons, but with the joint efforts, they were quickly transported to the top of the mountain to wait for the steel arm to take its place.

Zhang Xuewu walked among the soldiers cordially and asked how he was eating. He had paid for the ten yuan of settlement money he sent. He asked more about some grassroots officers Zhang Xuewu, such as whether he had any opinions on the positions he was holding? Do he have any suggestions on tactical arrangements?

It was the first time that many grassroots officers saw so many stars appear together. The generals of one or two golden stars on the shiny yellow collar seal put a lot of pressure on these young officers, but many people still expressed their suggestions. Zhang Xuewu immediately ordered people to record them all, because Zhang Xuewu always believed that only those at the forefront knew what was the most real.

A small company commander at the bottom of the 41st Division saw that Zhang Xuewu was easy to speak, so he boldly said, "Sir, my company defends a 500-meter front, and air leaks from all sides! At least one battalion's troops should be arranged here, which is in a trapezoidal system. I think the two levels of the company should have the right to require division-level artillery regiment fire support."

Zhang Xuewu asked the name of this bold little company commander, and then asked the deputy commander to record it and issue it to various troops as a guiding principle. The front-line companies and battalions are the key to artillery fire control, while the brigade and division level are responsible for allocating firepower compositions to confirm and avoid duplication or waste of firepower.

When inspecting the Zijin Mountain Fortress and Yuhuatai Fortress in the afternoon, Zhang Xuewu also participated in the excavation of fortifications and anti-tank trenches. Both ends of the streets in Nanjing urban area began to clean up some buildings that blocked the boundary and built street forts. The people in the city forced to evacuate whatever they wanted or not, demolished whatever they needed, buried a large number of landmines under the city walls, and set up fire channels marked out.

In Qinhuai, Confucius Temple, Shuangtang and other places where buildings are dense, buildings are cleaned up, and solid ones are selected to strengthen the constrainedness. The light and dark firepower points are equipped with complete equipment, and ammunition supply reserves are sufficient. In addition, Zhang Xuewu set up his command center in the central bank of Gulou. It can be said that Nanjing has many solid buildings, and these buildings can serve as constrained firepower points. If heavy artillery bombardment is not suitable for long-term bombardment, these constrained points will be difficult to completely destroy and break.

For some defending points, Zhang Xuewu used the most traditional earth-stacked defense, which is to pile up the soil layer to the same height after the wall or building, and then use solid soil layer to resist the Japanese artillery fire and direct firepower, and build three-layer shooting fire fortifications with wood in it, and use three-dimensional cross-fire firepower to deal a heavy blow to the Japanese offensive forces.

Zhang Xuewu estimated that he had only one week at most because he gave up the battle for positions outside Nanjing. It was not because Zhang Xuewu wanted to give up the battle for positions outside Nanjing, but because his troops were really limited. Once the established troops were put into repeated battles and consumption on the outside, it would inevitably affect the overall defense of Nanjing City. Moreover, the troops in the battle for the outside line lacked the necessary artillery cover, and the casualties would definitely be very shocking.

After the two main defense lines set up by Zhang Xuewu in Nanjing, Zhang Xuewu used Wulong Mountain, Qixia Mountain, Zijin Mountain, Yuhuatai and other strategic rushes as the point of defense, and used firepower and multiple positions to defend. He also prepared sufficient reserves and counterattack troops. Zhang Xuewu's intention was very simple, that is, to use the so-called gaps between the fortresses to lure the Japanese army to take risks and assault, and then use heavy artillery fire to divide the enemy's front and rear echelons, and use armored troops to make a large amount of vitality to consume the Japanese army's vitality. The first thing to destroy is the arrogance of the *** people.

In Zhang Xuewu's view, it is actually difficult to have relatively successful tactics to use in Nanjing. For example, in the Sun Yat-sen Mausoleum area, Chiang Kai-shek repeatedly warned Zhang Xuewu not to make up for the Sun Yat-sen Mausoleum. Zhang Xuewu still dug up the walls of the Sun Yat-sen Mausoleum and dug a large number of tunnels on the mountains. Due to the tight time, Zhang Xuewu mobilized more than 5,000 coal mine workers from Gao'an and other places to quickly dig the tunnels with squeeze and blasting techniques, and cooperate with the surface positions. In fact, this is a small replica of Shangganling. The main position of Zijin Mountain first and second peaks is combined with the tunnel positions supported by logs, and is equipped with heavy artillery in Shangyanziji and heavy artillery groups in Jiangbei.
