The Governor's Mansion of Jiaoao on the half slope of the eastern foothills of Mount Dietrich, perhaps because Qingdao was taken over too hastily, the German colonial name is still used in Qingdao city and the entire Jiaoao.

Although the Jiaoao Governor's Mansion is still a solid German-style building, it has been listed as the "Jiaoao Defense Command". This is the heart of the entire Jiaoao defense. Dozens of sandbag fortifications can be seen near the Governor's Mansion.

Machine guns were mounted on the fortifications, and soldiers wearing helmets looked around vigilantly. On the road leading to the headquarters, there were only sandbags and wire fences.

At noon, the officers of the 3rd Jiangsu Army Division had gathered at the headquarters. Among them was Wang Yulin, commander of the 7th Infantry Regiment who was tall but somewhat thin. He was a member of the third phase of the Japanese Army Non-commissioned Officer School sent by the Manchu Qing Dynasty to study in Japan.

Infantry cadets, Zhang Xueling, commander of the 8th Infantry Regiment with a smile on his face from time to time, Li Yunlong, commander of the 9th Infantry Regiment, Yang Shouzhu of the Division Cavalry Battalion, and Shan Qipeng, who never showed any emotional changes on his face

, without exception, they all have one thing in common, they all graduated from the Japanese Army Military Academy.

At this time, they were about to fight bloody battles with their former classmates and teachers in Qingdao. Compared with their solemnity, the deputy commanders and staff officers who graduated from the Longhai Armed Police Police School looked eager to try.

, they are young and energetic, even more eager for war than their superiors.

"Sir is here!"

The command from the guard outside the door came, and Han Wu appeared at the door. The officers' leather boots and spurs rang in unison, and they stood at attention at the door.

After entering the conference room, Han Wu, with a solemn expression, first took a look at the people standing in the conference room, then reached out and took a telegram from the adjutant's hand.

"Huaihai Economic Strategy Envoy's office is sending a message!"

The spurs sounded again.

"Gentlemen of the Third Division of the Jiangsu Army: Defend Jiao'ao. Although we adhere to the principle of not being the first to attack, if the Japanese attack brazenly, defend Jiao'ao and fight to the last man!"

After the order was issued, no one was surprised. In the past two days, the commander's speech has been constantly played on the radio. It can be said that the commander's speech has clearly and unmistakably conveyed a signal that even if you die in battle, you will not compromise.

.

"Everyone, the time limit for the Japanese ultimatum has now passed. According to the information we have obtained, the Japanese fleet will arrive in Qingdao tomorrow morning, and the Japanese army troops will also board the ship and set off. The war is about to begin!"

After the division chief of staff Xiao Xiao conveyed the information, Han Wu asked everyone to mobilize their opinions.

"Now is not the time to argue. Now we only have one issue that needs to be discussed. First, defend Jiao'ao, second, defend Jiao'ao, and third, still defend Jiao'ao!"

Han Wu's words set the tone for the meeting.

"Sir, I believe that all ministries must be immediately ordered to implement strict military discipline. For those in the front who retreat without authorization, and if the officers and soldiers in the rear fail to receive the retreat instruction from the headquarters, the troops in the rear must immediately implement battlefield discipline!"

Han Wu glanced at Wang Yulin without any hesitation.

"Deliver the order after the meeting!"

"Sir, our division is stationed around Qingdao. The German army has set up four internal and external lines of defense. The first two lines are the outer lines, and the third and fourth lines are the inner lines. After our army was stationed, in order to strengthen defense, no additional lines of defense were established. According to the external light

In the plain of inner gravity, the main force of our army is deployed on the inner defense line, using the fortresses of Chimin Mountain, Bismarck Mountain and Moltke Mountain in the suburbs of Qingdao as the core to build the defense of Qingdao... The entire fortress has 6 main forts and 4 facing the sea.

, 2 for the land, equipped with a total of 4 280mm guns, 2 240mm guns, 4 210mm guns, 7 150mm guns and 4 105mm guns, in addition to several 88mm guns and old 120mm guns originally belonging to the Qing Dynasty Army

.A total of 5,750 people are stationed in these forts and 5 multi-faceted bastions. The terrain is very high and dangerous..."

While Xiao Xiao was talking, he pointed at several locations on the map.

"The Second Division will arrive in Qingdao tomorrow. I think our army should strengthen its external defense. According to the terrain of Qingdao, the Japanese army will avoid attacking from the front and choose to go ashore behind the fort, so we use the mountaintop fortifications to monitor the sea...

"

Fortress defense is the first time for the Jiangsu Army. Although they have enough machine guns and mortars, the coastal fortress defense battle is unfamiliar to all of them. At this time, they are just executing the "textbook style"

"Prepare.

"Where is Captain Fells, chief engineer of the fort?"

Looking into the conference room, Han Wu did not see the fortress engineer. Captain Fels was a German officer. Although he was now an alien from the enemy country, he was wearing the uniform of the Jiangsu Army.

At this time, Han Wu was most worried that these German soldiers would not be able to do their best to help him defend Qingdao because of the "China-Germany declaration of war". The fort could not do without them.

"Captain Fells will be here soon! He has been responsible for strengthening the defense of various fortresses. I have sent someone to ask him to come over!"

A few minutes later, Captain Fells came. As soon as he entered the conference room, he showed another map, which was a new map of Jiao'ao Fortress.

"Sir, regarding the situation of land forts and fortresses, in addition to the six forts and five multi-faceted bastions that were left behind before, we have now built 12 new simple multi-faceted bastions,"

The simple multi-faceted bastion he mentioned is actually a half-meter-thick reinforced concrete wall with a large number of perforations and a position of four to five mortars in the center of the fortress. It is more like

It was a trench, not a fortress, but what amazed Fels was the number of machine guns in this Chinese army. Previously, there were only 12 Maxim machine guns in Qingdao, and two of them were broken off from warships.

After the Chinese army was stationed, they carried more than 500 machine guns with the troops. After that, they took out 600 machine guns from their reserves, and the shooting holes of those fortresses were completely transformed into machine gun shooting holes.

, but even so, they still continued to replenish machine guns, and seemed to be preparing to turn the entire Jiao'ao into a fortress composed of machine guns and mortars. Maybe they did not have large-caliber artillery, but Fels believed that they only needed machine guns.

, enough to make those Japanese pay a heavy price.

"Forts No. 7 and No. 8 are currently only undergoing excavation work. If they are to be completed, it will take at least three or four months. In short, it can be said that the outer lines of Jiao'ao are simply not able to constitute the permanent construction you require.

Prepare fortifications, at least before the Japanese arrive!"

The commander gave him enough people, enough materials, and enough funds, but not enough time. Without time, it was impossible to build the fortress he hoped for anyway.

time!

In the Japanese Consulate in Qingdao, Consul Oda looked at the Chinese soldiers building fortifications on the street. Although he was full of contempt for the Chinese army, looking at their seriousness, he really doubted that they might actually fight.

to the end.

"We will never withdraw from Jiao'ao!"

Two hours ago, Commander Han sent someone to respond to the ultimatum.

They were seizing the time to make preparations. They dug out paving stones on the street and built fortifications in the middle of the street and on both sides.

"Let every inch of land in Jiao'ao turn into a graveyard for the invaders!"

On the wall opposite the consulate, a temporarily organized youth team painted slogans.

It seems that the army really needs to prepare for a strong attack!

Xiaotian sighed helplessly, will Qingdao become Lushun? He doesn't know, but at least one thing he is sure of is that the Chinese army will never withdraw from Qingdao.

"It seems we can only capture Qingdao!"

The west wind is strong and the sky is filled with stars. In the Tuandao area, the runway paved with thick sleepers stretches into the sea water. This is the seaplane that thousands of workers spent two days building. However, at this time, the seaplane is still

It has not yet been completed, and there are still workers working overtime to lay the sleeper slides.

Behind the slide, in several continuous asbestos-roofed hangars, twelve seaplanes are arranged neatly. This is the second squadron of the Jiangsu Army Air Force that has just arrived from Lianyungang, and the Jiangsu Army Air Force may also be

The world's largest "air combat force", as for the second squadron, is probably the world's largest water attack aircraft squadron. Under the lights, the pilots are checking the aircraft engine by themselves, and the rear-seat shooters are checking the machine guns, the aircraft

It was deployed in advance, but the ground crew was still halfway there.

"Without torpedoes, if a fight breaks out tomorrow, we will definitely be out of luck!"

Li Yunlong said to Cao Bin that he was the weapons operator, and he was responsible for the rear seat machine gun and torpedo depth setting.

"Isn't that right? The captain always thinks about safety, but if we brought torpedoes when we came here, we might be able to show off our skills tomorrow!"

As Cao Bin said this, he began to long for the scene of twelve attack planes carrying out torpedo attacks on the Japanese warships invading Qingdao.

"Show off your skills? There's no need to show off at all!"

Li Wenjun, who was standing next to him, interjected, then pointed to the chart on the wall and said.

"I looked left and right, and I didn't see anything that could threaten us on this warship. The elevation angle is not that high, and we are flying fast and high, so it is difficult for rifles to threaten us. If we arrive

If we can form a surprise attack, maybe..."

"Raid!"

As the captain of the Second Squadron of the Jiangsu Army Air Force, Li Yunlong listened to Li Wenjun's words with a smile on his face. In fact, after receiving this order, he began to think about how to achieve the greatest results.

You want to become famous in one battle, but you only want to severely damage the enemy's army in one battle.

"Only a surprise attack!"

You must choose the right time for this raid. What kind of time is the most suitable time?

Holding the pencil between his fingers, he began to think about a suitable opportunity that could severely damage the enemy!

There is no fortress in Lianyungang.

This is a well-known fact. In fact, as a commercial port without "garrisons", fortresses cannot be built here at all. Although both Liandao on the opposite side of the mainland and Yuntai Mountain on the mainland are suitable for building coastal defense fortresses, they can be restricted.

Due to many constraints, especially political constraints, Lianyungang is not suitable for building a fortress, at least not politically mature.

"...According to our calculations, the cost of producing a 280mm coastal defense gun is 850,000 yuan, and a coastal defense fort costs another 550,000 yuan. Taking Liandao as an example, if six 280mm coastal defense guns are built,

For a coastal defense fortress with artillery as its main body, only six core forts require an expenditure of 8.4 million yuan. To equip it with no less than 15 150mm coastal defense guns, another 2 million yuan is needed. In addition, it needs to be equipped with other small and medium-caliber artillery turrets and machine gun forts.

An additional investment of 2 million yuan is required. At the same time, an underground passage needs to be built to connect the military camp and the fort, which requires an additional 1.5 million yuan in funding. Therefore, the Liandao Fortress requires an investment of at least 14 million yuan!"

Standing on Yingyou Mountain in Liandao, Zheng Zixi explained in detail the construction expenditure of Lianyungang Coastal Defense Fortress to the envoy. He was not only the only artillery expert in Lianyungang, but also a coastal defense expert. As early as in the UK.

14 million!

Although he can now get a huge sum of about 20 million per month by using fake pounds, Li Zicheng couldn't help but gasped when he suddenly heard Zheng Zixi mentioned that a fortress needed 14 million.

The reason why he is building a coastal defense fortress is because the air power he has always pinned on has only caused more than 40 aircraft until now. Of the more than 130 pilots, only 26 have completed aerial torpedo attacks.

Not only that, the planes could not go out on rainy days, so they finally went back to the original route and built a coastal defense fortress in Lianyun.

"The project of Liandao Fortress is divided into three phases. Each phase will complete the coastal defense fortress with two 280mm coastal defense guns as the core. The first phase of the project will take 3 months to complete, while the underground passage will take 14
