"How to find another way?" Lieutenant General Seishiro Itagaki asked.

"Avoid the fire point of the Shina people and attack from the underground!" Major General Seiichiro Yuhara said.

"You mean authentic?" Lieutenant General Seishiro Itagaki said with squinted eyes.

"Exactly, with that hill to contain, even if our army captures Datong City, it will pay an extremely high price, so I think that digging one or several tunnels leading directly to Datong City will definitely be able to take Datong City in one fell swoop and eliminate the Chinese army in the city." Major General Seiichiro Yuhara said.

Lieutenant General Seishiro Itagaki thought for a while and said: "Yo Xi, this idea is very good, but the excavation of the tunnel is a huge project, and it is easy to be discovered by the people of China, and at this time it needs to be reported to the front army headquarters for approval!" ”

"Your Excellency Commander, I think that the sooner the better, the government of China and Yan Xishan in the second war zone will not watch Chen Feng's troops be wiped out by our army, and when they draw their hands, they will inevitably send reinforcements, and it will be a big trouble to be surrounded by this branch of the army when the time comes." Major General Seiichiro Yuhara said loudly.

"Yo Xi, in this case, the task of digging tunnels will be entrusted to you to complete the fifteenth brigade independently, and I will let other troops harass and attack the Chinese army in the city day and night to cover for you." Lieutenant General Seishiro Itagaki said loudly.

"Hay!"

On the morning of the 18th, the Japanese army again organized a strong attack with superior forces, still using aircraft, artillery, and combat vehicles, and even used poison gas bombs, but the effect was still very small, and the hard fighting for a day yielded no results.

On the 19th, the Japanese army attacked again, but soon the defenders in the city found the problem, only a small number of Japanese troops participated in the attack today, and the vast majority of them were puppet soldiers, although these puppet soldiers were wearing the standard uniforms of the Japanese army, but they were still holding old weapons and equipment, which could not be hidden from the defenders in the city.

Moreover, compared with the Japanese army, the puppet army's will to fight was like mud, and it collapsed after a slight fight. Therefore, although the Japanese army organized an unprecedented 13 attacks throughout the day, the intensity of the battle was far less than that of the previous two days.

For three days, the Japanese attack was as bad as ever, and although they continued to attack day and night, it was often the defenders who retreated as soon as they counterattacked. Despite this, the 222 Brigade did not dare to slack off, because two days ago, the Japanese army took advantage of the slack of the defenders to organize a strong attack, that time actually let the Japanese combat troops hit the city of Datong, and also planted explosives, fortunately, the strength of the Datong city wall exceeded the imagination of the Japanese army, more than a dozen explosives bags did not blow up the city wall, but despite this, the defenders were scared out of a cold sweat.

Shilipu Town. Joint Command of the Japanese Army.

"Yu Yuanjun, how is the excavation of the tunnel?" You, Seishiro Itagaki asked in a deep voice.

"Report to Your Excellency the commander, you have already dug eight hundred meters, and there are still more than six hundred meters away from Datong City, but the deeper you dig, the more difficult it becomes, mainly because of the lack of oxygen." Major General Seiichiro Yuhara replied.

"I don't care about these, I just want the result, I just want to know when the tunnel can be dug into Datong City?" Seishiro Itagaki said coldly.

"According to the current progress, it will take another three days to open the tunnel into Datong City." Major General Seiichiro Yuhara said.

"Okay, I'll let the troops on the front line hold out for another three days, in order to cover your department to dig tunnels and not be discovered by the people, our army has lost more than 23,000 people in five days, although the Imperial Association Army accounts for more than half, but there are still more than 10,000 casualties among the Imperial Army warriors." Itagaki Seishiro Road.

"Your Excellency, Commander, please rest assured, the humble post will definitely not disappoint you!"

On November 25, the cavalry group sent a telegram that they had arrived at the outskirts of Kulen, and that the special combat team had infiltrated the city of Kulen in makeup last night, and had obtained a detailed map of the city of Kulen.

The luck of the cavalry group was indeed good, at this time there was only one brigade of defenders in the city of Kulen, and this brigade was all new recruits who had just been transferred from the Japanese mainland, and their combat effectiveness was very limited.

Chen Feng instructed that after drawing up a detailed battle plan, the cavalry group could launch a general attack on Kulen in the early morning of the 26th, and it was imperative to kill all the Japanese troops in Mongolia with one blow and annihilate the headquarters of the Japanese army in Mongolia, and never let one go.

At the same time, Chen Feng ordered the soldiers of the Duqi Brigade on Daqingshan to enter the two county towns of Xinghe and Zhangbei through a secret passage on the night of the 26th, and launched an attack on the defenders of Xinghe and Zhangbei.

The 223rd and 224th brigades also received orders to launch an attack on the Japanese troops in Jining, Shangdu, Fengzhen and Tianzhen in the early morning of the 26th. Chen Feng himself took the team directly under the military department and 200 brigades to deal with it.

At 11 o'clock in the evening of the 25th, the Shilipu Japanese joint headquarters was still brightly lit, and all the senior officers of the Japanese army were there, although there were bursts of artillery and gunfire not far away, but all the Japanese officers were extremely excited, and the news came from the 15th Brigade that had just been independently mixed into the 15th Brigade that the tunnel had been dug to a distance of 50 meters under Datong City, and it would take three hours at most to dig into Datong City.

In Datong City, Li Wensheng's mood was very melancholy, the Japanese army's behavior during this period was very abnormal, and the frequency of attacks was extremely high, but it was not fierce at all, and it could be seen that their minds did not seem to be on the battle, as if they were hiding something.

After analyzing with a large group of officers for several days, he didn't think of what tricks the little devil was playing, which made Li Wensheng very depressed.

"Division, the commander of the third battalion of the 309th Regiment, who had just been stationed on the eastern city wall, reported that their soldiers were patrolling when they heard a thudding sound coming from underground." Li Jianhua, deputy commander of the 222nd Brigade, came in and reported.

Li Wensheng and Hu Tiesheng glanced at each other, and said at the same time: "Authentic! ”

After Li Jianhua's reminder, Li Wensheng and Hu Tiesheng both thought of what the little devil's abnormal behavior was for during this time, it turned out that these troops on the ground were just a disguise, mainly to cover the construction of the underground troops and dig tunnels, and the little devils were really cunning.

Thinking about this, Li Wensheng and Hu Tiesheng are not worried, they know the city fortifications of Datong City very well, and it is absolutely impossible for the Japanese army to enter the city by digging tunnels, because the moat around the city is the nemesis of all tunnels.

According to the military seat that day, the moat of Datong is fifteen meters deep, and the side near the city wall is built with reinforced concrete several meters thick, if the Japanese army's tunnel is fifteen meters below the ground, then it is really possible to enter Datong City, but if it is above fifteen meters, then I'm sorry, no matter what direction it is dug from, the result is the same, that is, digging through the moat, and everyone in the tunnel will be drowned by the swarming river.

In addition, the amount of work in the 15-meter-deep tunnel is extremely huge, and it is absolutely not possible to dig it well in 10 days or 8 days, so Li Wensheng judged that the tunnel dug by the Japanese army this time should be more than 15 meters.

Thinking of this, Li Wensheng said disdainfully: "The little devil is really scheming, do you really think that the military seat is a fool, I have already guarded against this hand of the dog day, and passed my order: sound the first-level alarm, all the troops are ready for battle, order the air defense regiment and the machine gun regiment to carry all the light and heavy weapons to the city, and Lao Tzu will teach the old devil Itagaki Seishiro a good lesson today." ”

Shilipu Town, the joint headquarters of the Japanese army.

"Your Excellency, the commander of the division, the 15th Brigade of the Independent Mixed Brigade called and said that there are still ten meters, and it can be connected within half an hour." A captain staff officer came in and reported.

"Yo Xi, order the troops, launch an attack according to the original plan, **Jun East Gate will be handed over to your 26th Division, the South Gate is responsible for the 9th Brigade, the 2nd Infantry Division of the Imperial Cooperative Army, and the 9th Infantry Division of the Imperial Cooperative Army, the North Gate is responsible for the 21st Brigade, the West Gate is responsible for the Yamashita Brigade, and the 4th Cavalry Brigade is responsible for containing the Chinese army outside the city. Ladies and gentlemen, it is up to you whether the Imperial Japanese Army can be disgraced before the snow, and start acting! Seishiro Itagaki ordered.

"Hay, the Great Japanese Empire is onboard! His Majesty the Emperor is mounted on board! ”

"The Great Japanese Empire is onboard! His Majesty the Emperor is mounted on board! ”

"The Great Japanese Empire is onboard! His Majesty the Emperor is mounted on board! ”

The sudden and fierce attack of the Japanese army did not panic the defenders, but made the defenders very happy, because just now the command headquarters transferred all the troops in the city to the city, including the air defense regiment that has been used to defend against Japanese aircraft.

"Bang bang bang!" "Da Da Da!"

The Japanese army was not afraid of death, and followed the armored vehicles and chariots with bayonets towards the Datong city wall, although the opposite side was extremely fierce, and in front of a large number of anti-aircraft machine guns, even the Japanese tanks were quickly killed or lying on their stomachs, but their infantry still strode forward.

Itagaki Seishiro was very satisfied with the courage of the Imperial Japanese Army, although the casualties of such an attack would be greater, but such an attack would not last long, once the underground passage was dug through, the 15th Brigade of the Independent Mixed Brigade would attack the city along the tunnel, and the Chinese army in the city would be defeated without a fight, and the battle would be decided.

However, the ideal is beautiful, but the reality is skinny. Half an hour after the Japanese launched a full-scale attack, the 15th Brigade of the Independent Mixed Brigade received news that the tunnel was out of water.

In fact, before the excavation of the tunnel, Major General Seiichiro Yuhara thought of the leakage, so he found a large amount of information on the defense of Datong City, and knew that the moat of Datong City was only 3 meters deep and 5 meters wide, as long as the depth of the tunnel was below six meters, it was guaranteed that there would be no trouble, so when there were still more than 30 meters away from the moat, he ordered the troops digging the tunnel to dig deeper, and one side dug the moat.

Unexpectedly, the depth of the tunnel was up to 8 meters deep and still could not escape this doom, when the soldiers digging the tunnel saw a little water droplet oozing from the wall of the tunnel, before he could shout, he saw that the water droplet turned into a stream, and soon the earth wall at the end of the tunnel collapsed, and a huge stream of water poured down the tunnel, and soon filled the tunnel.
