Shimen, the headquarters of the Fourth Army.

Major General Toshihide Fujimoto strode into Tada's office, and immediately retracted his feet and said, "Your Excellency, Commander! ”

Toshihide Fujimoto is only 36 years old, born into a family of samurai, studied in Germany and systematically studied military theory of mountain warfare, and is known as the "flower of famous generals" in military circles; five days ago, Toshihide Fujimoto had just been transferred from the commander of the 1st Infantry Brigade of the 1st Division of the Kwantung Army to the chief of staff of the Fourth Army.

"Fujimoto-kun." Tada Jun nodded, motioned for Toshihide Fujimoto to sit down, and then asked, "The front army headquarters just sent a telegram ordering the Fourth Army to seize Yulu County, what do you think about this?" ”

Toshihide Fujimoto asked, "Your Excellency Commander, did you only capture Deer County?" ”

"Yes." Tada Jun said, "Fujimoto-kun, do you have any objections to this?" ”

Fujimoto Toshihide shook his head and said: "At present, the focus of the battle of the Imperial Army is the frontal battlefield, and the garrison in North China is relatively empty, and it is indeed not appropriate to enter the Taihang Mountains on a large scale at this time. ”

Tada Jun nodded happily and said, "Fujimoto-kun, your analysis is very correct. ”

Fujimoto Toshihide said indifferently: "Your Excellency, Commander, the people of China will not be restrained." ”

"Oh?" Tada had already heard the meaning of Fujimoto Toshihide's words and asked, "Is there a new situation?" ”

Fujimoto Toshihide nodded and said: "Ikegami Daisa of the secret service agency has just reported to me that Lingshou, Pingshan, Luancheng, Haocheng and other counties have all been occupied by the China Army, which should be the 39th Group Army of China, and according to the report of the aviation scouts, there are dozens of battalion-sized China Army in the South Hebei Plain, and the final intention is unknown. ”

"Huh?" Tada Jun said awe-inspiringly, "Could it be that the people of China have already broken through from the Jingcheng Pass?" ”

Fujimoto Toshihide shook his head and said: "It should only be a part of the troops operating in the South Hebei Plain, and the main force of the 39th Group Army, especially the Baoshan Division, should still be in Jingcheng Pass." "The flower of the little devil's famous general is still a bit level, although the intelligence is limited, but with such a little clue, I guessed the ins and outs of the whole thing.

Tada Jun thought for a while and said, "Fujimoto-kun, immediately report this situation to the Front Army Headquarters!" ”

Toshihide Fujimoto immediately took the order, and less than ten minutes later, he returned with a new battle order.

"Your Excellency, Commander." Toshihide Fujimoto said, "The Front Army Headquarters ordered us to abandon the plan to attack Houlu County, and use the 6th Division to hold Shimen and Zhengding, monitor the Baoshan Division, and use the 13th Division as the main force, supplemented by Reading Power to form the 11th Brigade to carry out a large-scale sweeping operation in southern Hebei, and be sure to annihilate all the Chinese armed forces operating in southern Hebei!" ”

…………

Tumen is closed to the right, hugging the calf mountain.

Yue Weihan was accompanying Mao Yisheng, Mei Xiaochun, Qin Qiuyang and other three experts to inspect the terrain.

Yue Weihan said to the three experts as he walked: "The purpose of building the Tumen Fortress is to completely cut off the Zhengtai Railway and the Shitai Highway, so that Shanxi's coal, iron ore and other resources cannot be transported, and at the same time, it is also impossible for the army's tanks, artillery, armored vehicles, heavy vehicles and other heavy equipment to enter the hinterland of Taihang Mountain, so as to ensure the safety of the Taihang Base Area!" ”

Mao Yisheng said: "Commander-in-Chief Yue, I would like to hear your general idea of Tumen Fortress. ”

"My general idea is like this, based on Conch Mountain and Baoqian Mountain, build two large mother bunkers, completely lock the mouth of the well, and then build small mother bunkers on more than a dozen hills around to protect Conch Mountain and Baoqian Mountain, and each mother bunker is supplemented by a different number of sub-bunkers around each mother bunker, and there must be tunnels between the mother bunker and the sub-mother bunker, and it must be able to withstand the bombardment of 500 pounds of aerial bombs or the shelling of 150mm caliber heavy artillery!"

Mao Yisheng nodded and asked, "Commander-in-Chief Yue, how many troops do you plan to station in this fortress?" ”

Yue Weihan thought for a moment and replied, "One regiment, plus non-combatants, about three thousand people!" ”

Historically, the army that held the Songshan fortress only had a third-rate remnant wing, and the first-line infantry was less than a thousand, but it was stunned to block 20,000 [***] for three months, if it was not for the final [***] to adopt blasting tactics, the arm's blocking time would definitely be longer, and the casualty ratio of the two armies would definitely be far greater than 1:8!

Mao Yisheng and the other three experts are obviously far stronger than the officers of the Yue Army in civil engineering, therefore, the technical indicators of the Tumen Fortress will definitely exceed the Songshan Fortress in history, and with the Tumen Fortress, with the combat effectiveness of the Baoshan Division, one regiment is enough to block a field division of the Yue Army for at least six months!

It is said that it is nothing for the army to mobilize more troops, because the width of the well is so wide.

Even if the army mobilized 10 field divisions to sweep up, it could only fill in one division at a time.

So, as long as there are enough ammunition and food reserves, it is enough for the Tumen fortress to have a regimental garrison.

If the army has a mountain division in the real sense, it can completely bypass the Tumen fortress from the side and directly attack the hinterland of the Taihang base area, but unfortunately, there is never a real mountain division in the battle sequence of the army, and there is not even a mountain brigade in the real sense!

Of course, the army can also use field divisions as mountain divisions, but the effect is not easy to say.

The field divisions and regiments of the army have long been accustomed to the tactic of "the artillery charges after the infantry shoots, and the infantry charges after the artillery bombardment." Moreover, what they usually practice is infantry and artillery coordination; if they suddenly lose the fire support of the tank detachment and the field artillery wing, and there is no logistical support from the baggage wing, how much combat effectiveness will remain? And how many days can you continue to fight?

If such a field division enters the hinterland of the Taihang base area, it will definitely be looking for death!

Mao Yisheng nodded, and said: "Commander-in-Chief Yue, I just counted, in addition to the two main peaks of Conch Mountain and Baoqian Mountain, there are sixteen hills around, in order to make it easier to distinguish, I will now mark them with '1' to '16', which means that Tumen Fortress needs to build eighteen sub-mother bunker groups!" ”

"Yes." Yue Weihan nodded, and said, "These eighteen sub-mother bunkers must all be connected by tunnels, each mother fort must be able to provide fire support to the surrounding sub-forts, and the sub-forts and the adjacent sub-forts must also be able to provide fire support, and there must be no shooting blind spots!" ”

"Understood." Mao Yisheng nodded, and said, "And each mother fort must be designed as a multi-layer structure, with the shooting layer above the ground exposed, and the rest of the facilities such as arsenals, rooms, storage rooms, power distribution rooms, and dormitories for officers and soldiers must be hidden underground, and all facilities must ensure the living needs of at least 3,000 people!" ”

Yue Weihan said: "If it is possible, it can be designed to the specification of five thousand people." ”

"We try our best." Mao Yisheng nodded, and then he and the other two experts began to mark on the map, and after marking the corresponding peaks on the map, the three experts each took out a notebook and began to draw a sketch of the mountain of Baoqi Mountain, and then climbed the conch mountain and the sixteen hills on the periphery respectively, and drew the mountain sketch one by one.

He was busy until dark, and then Yue Weihan accompanied the three experts back to the group army headquarters.

As soon as Yue Weihan entered the office and sat down, before he could drink a saliva, Liu Yi hurriedly walked in with a few telegrams and said to Yue Weihan: "Boss, the little devil has made a move!" ”

Yue Weihan took a big sip of water and motioned for Liu Yi to continue.

Liu Yi paused, and then said: "The 129th Division of the Eighth Route Army has just sent a report on the battle situation, the army stationed in Shanxi has occupied Pingding County, and the 386 Brigade stationed in Pingding County has been transferred. ”

"Where's the county seat of Deer?" Yue Weihan hurriedly put down the water cup and got up, and asked loudly, "Has the 6th Regiment stationed in Luxian County been attacked by the Yue army?" ”

Huolu County is located in the middle of Tumen Pass and Shimen, about 30 miles away from Shimen, but less than 10 miles away from Tumen Pass!

If the 6th and 13th divisions of the army do their best to attack the county seat of Houlu, the Baoshan division will definitely not be able to hold it, and once the county town of Houlu is lost, the construction project of the Tumen fortress will be in trouble, because the Tumen Pass is too close to the county town of Houlu, even if it is constructed at night, it is difficult to hide from the eyes of the person!

Once the construction of the Tumen Fortress is exposed in advance, the consequences will be unimaginable.

As long as the little devil takes advantage of the fact that the main structure of the project has not yet been built, the bombers will be dispatched to drop a few heavy aerial bombs, which is enough to strangle the Tumen Fortress in the rocking blue, and if a few more large-caliber howitzers are transferred and dozens of cannons are fired in the direction of Tumen Pass every day, the Tumen Fortress will never want to be built.

"Nope." Liu Yi said, "The army did not attack Luxian County. ”

"Great!" Yue Weihan was immediately excited when he heard this, and said, "The little devil is still fooled after all!" ”

"And that's to be expected." Liu Yi was also rejoicing, and said, "If the army attacks the county town of Lu, it is nothing more than to block the mouth of the well, but if we shrink in the Jingcheng Pass and can't get out, it doesn't matter whether the army blocks it or not, but the more than 30 battalions that can be scattered can pose a fatal threat to the army, if the army is left alone, in a few months, these 30 battalions can become more than 30 regiments, and the threat is not ordinary." ”

Yue Weihan nodded and said, "Anyway, the thirty or so battalions that were scattered out have successfully diverted the attention of the Southern Hebei Army, and also won us valuable time to build the Tumen Fortress!" ”

After saying this, Yue Weihan said again: "Chief of Staff, let Zhao Xinyi put aside the anti-war work first, and she will be responsible for the work of rushing equipment into the mountain, and the preparation for the construction of the power plant and cement plant will be handed over to Pi Xiaocheng with full responsibility. ”
