Now, the little devil sneaked into the submarine from the northern waterway, entered the Datong River waterway for 10 kilometers, and was trapped by the "mobile anti-submarine net" arranged, which was the expected outcome.

Bai Shujie believes that a submarine without power is the best submarine for little devils.

The so-called "mobile anti-submarine net", that is, when one's own ship does not pass by, it is put into the water; When their own ships pass through here, they put them away.

This kind of retraction and release process does not need to be kept secret, and Bai Shujie ordered Zhang Bingyang to use a fishing boat to take charge of this matter here. People who don't know the truth still think that people are fishing.

Although the order was issued, Bai Shujie was still not at ease, and at the same time asked Zhao Jinxi to inform the security forces and Shi Liancheng's first division to strengthen the vigilance on the southwest coast to prevent the enemy from attacking the west.

At the same time, he made another phone call to the Air Force Command and ordered the fighter squadron at the Jiangnan airfield to be ready to transfer to the capital and ensure that it could take to the air for combat at any time.

When Bai Shujie rushed to Jinshanli south of the Datong River estuary, that is, the headquarters of the shore artillery fortress, he found that Zhang Bingyang, the commander of the navy, was also here.

"How's it going?"

Bai Shujie came to the fortress, pushed Zhang Bingyang, who was using the cannon scope to observe the sea surface, and then personally manipulated the telescope to observe the sea surface.

Zhang Bingyang said with a smile: "The little devil's submarine should have been trapped by the anti-submarine net, and now it has not floated for the time being." But they were not willing to fail, and even fired a torpedo bombardment, which has just stopped for a while. ”

At this moment, a loud noise was heard on the river in the north, and a huge column of water suddenly rose into the sky.

"The little devil here finally can't hold on!" Bai Shujie turned the telescope to the north and looked at it, and suddenly smiled: "What's the use of the fuck?" There's nothing on the shore here, boom! ”

Zhang Bingyang shook his head: "Commander-in-chief, this submarine is not dead yet, they are slowly turning around, otherwise, it is impossible for the torpedo to hit the shore, but to shoot along the river." Could it be that their propellers have been gotten rid of? ”

"Not necessarily, not necessarily!" Bai Shujie observed the surface of the river with a telescope, and said after a deep sigh: "It is summer now, and it is also the peak water period of the Datong River, and the flow rate of water is very fast. The submarine of the little devil loses power and will be swept away by the flood to move. ”

"Now the submarine is crossing, which is not necessarily a bad thing. They fired torpedoes, presumably in an attempt to destroy the anti-submarine nets, and then float into the sea. You hurriedly send people to continue to lay out anti-submarine nets downstream, and you must not let the little devils float into the sea! As long as the little devil doesn't detonate the fish in the ship, this submarine is Lao Tzu! ”

Rumble! Rumble! Rumble!

At this time, more than 20 kilometers southwest of the sea, a large explosion suddenly sounded. Naturally, I couldn't see anything clearly at night, but the slight tremor in the air could still make people feel the huge power of the explosion.

Bai Shujie looked at it with a telescope for a long time without results, so he turned his head and asked Zhang Bingyang: "How many people are there on the Jiaodao base?" I looked at the distance of the bombing, not far south of Jiao Island, and it seemed that the submarine of the little devil was preparing to break the net. ”

Zhang Bingyang said with a smile: "The third escort formation retreats to the Cangyunli Military Port every night, and there are fishing boats moored outside. With a platoon of observation sentries from the Coast Defense Force on it, we were left with only seven sonar observers and two walkie-talkies. ”

Bai Shujie nodded, and then grabbed the red phone of the fortress headquarters: "Order all radar base stations and high-power transmitters along the coastline to turn on all the surrounding communication signals for full channel coverage and interference." ”

"Commander-in-chief, if you come like this, we won't be able to send a telegram." Zhang Bingyang was a little surprised: "While paralyzing the enemy, our own radio communications were also paralyzed. ”

Bai Shujie smiled slightly: "What are you afraid of?" Our own people are on the island, and the two-line phone is not guaranteed to work? According to the calculation of the maximum time that the little devil submarine can be lurking, as long as the interference is until tomorrow morning. ”

"If they don't float, they're all going to suffocate in the submarine. Then you can never think about floating again, you can only wait for Lao Tzu to send someone down to fish it up. ”

"Well, the air defense units of your naval command can now turn on all the searchlights and conduct a search of the sea surface. At the same time, all sonar listeners were ordered to be on full alert to prevent the enemy from having follow-up troops. ”

It turned out that Bai Shujie knew that the most advanced submarine of the little devil at present, the longest battery can be used is only 12 hours.

Of course, the little devil's submarine has diesel generators. But sinking to the bottom of the sea without air replenishment, if you start a diesel generator, you will die faster.

If the little devil turns off the power inside the submarine and gets dark, of course it will do. The problem is that oxygen is still not available indefinitely.

The submarines of the little devil's era generally have 60-120 people in them. Even if they use "oxygen regeneration pill boards", or high-pressure oxygen cylinders to release oxygen, or oxygen candles, dozens or hundreds of people can only last about 10 hours.

It's not that there is not enough oxygen, but that there is more and more nitrogen and carbon dioxide in the submarine, and if you don't start the ventilation machine in order to keep the battery charged, there is no way to get the nitrogen and carbon dioxide out.

Although nitrogen is not poisonous, all the space in the submarine has become nitrogen, and with the carbon dioxide exhaled, it is not far from suffocation.

At about three o'clock in the morning, Bai Shujie was sitting at the table and napping, when a rapid bell rang: Jingle bell-jingle bell--Zhang Bingyang had already grabbed the phone and listened for a while, then turned around and shouted: "Commander-in-chief, the Jiangkou surveillance post called, and the ship that first broke into the Datong River has slowly floated. How to deal with it? ”

"Don't board the ship lightly to prevent the little devil from blowing himself up!" Bai Shujie suddenly came to his senses: "Open the cannon and destroy the bridge of the submarine so that they can't dive!" Don't bomb the hull for a while, then shout, order the enemy to surrender and spare them from dying! ”

Although he really wanted to see what kind of submarine it was, Bai Shujie knew that he couldn't mess around at this time. If the little devil comes to self-destruct, it will be bad to use the reserve torpedoes to play the same trick.

If Bai Shujie didn't move, Zhang Bingyang could only accompany him, and the commander in the fortress headquarters turned out to be just a battalion commander under Shi Liancheng, so he didn't dare to talk nonsense.

In a blink of an eye, it was five o'clock in the morning, and the phone finally rang, and the voice of the Jiangkou surveillance post was clearly heard at five o'clock in the morning: "Report to the commander, the little devil's submarine has been taken!" ”

"Because the little devil just came up to breathe, not to surrender. So one of our platoons used forced boarding, and then used biological grenades to capture 47 people. As for whether the submarine was damaged, it needs to be identified by a special person. ”

Zhang Bingyang did not hesitate, and immediately called the Cangyunli Shipyard and asked them to quickly send a tugboat to tow the submarine away, so as not to have too many dreams at night.

After a busy time, it was already seven o'clock in the morning, and Bai Shujie was just about to return to the headquarters, when the phone rang again, and at the same time, the siren began to scream bitterly - there was an enemy plane approaching!

Because Bai Shujie had already given an order to the Air Force Command last night, in less than ten minutes, the roar of planes had already been heard in the east, and six fighters appeared in the sky. Biplane fighters, Kawasaki Type 95 fighters, this is two formations of the Flying Tiger squadron that took off from Jiangnan Airport.

Their task is to cooperate with the coastal air defense forces, so they are the fastest. The main task is to find out what kind of aircraft is coming, and then provide a basis for decision-making by the ground forces and the air force command.

Bai Shujie did not continue to look at the plane in the sky, but grabbed the phone: "Air Defense Warning Center, how is the situation?" ”

"Report to the commander-in-chief: the radar found a large group of aircraft, no less than 9 enemy aircraft! At present, the distance is close to 40 kilometers, and the model is unknown! ”

"Continue to keep a close watch while intensifying the search for the sea!" Bai Shujie put down the phone, and then grabbed it again: "Do you want to take over the duty room of the Air Force Headquarters?" I'm Bai Shujie! Order all 24 fighters of the Flying Dragon Squadron to take to the air and keep the enemy aircraft out of the waters off Jiaodao! ”

"Light bombers dispatch a three-plane formation to patrol the coastline, and if they find an enemy warship approaching, immediately bomb it!"

After putting down the phone, Bai Shujie said to Zhang Bingyang: "You go back to your command position immediately, you don't have to accompany me here." The Third Escort Formation was ready to go out to block the mouth of the Datong River, and the First and Second Formations, which were being refitted, immediately evacuated and hidden. At the same time, let's find out about the situation on Jiaodao and how the two submarines are doing. ”

"Damn, I'm afraid the little devil already knows that his cruise ship has been hijacked, and suspects that we did it. First of all, they used submarines to sneak attack, but all of them lost contact. Now that the aviation is out again, it seems that it will not rest on its laurels. ”

Zhang Bingyang turned around and went out, jumped into his jeep and ran. It didn't take long for Huang Qiaoyun's car to come to the entrance of the fortress headquarters, followed by 12 newly modified DW40mm quadruple anti-aircraft guns.

Last time, Xiao Lamei blamed Bai Shujie for dismantling 24 tanks and converting them into half-track tractors, which is now this kind of quadruple anti-aircraft gun, but I didn't expect Huang Qiaoyun to take half of it as soon as he came out.

The soldiers of the guard regiment are all elite soldiers. There is no need for Huang Qiaoyun, the regiment commander, to talk nonsense, the convoy below has already quickly seized the commanding heights around it, surrounding the entire coastal defense fortress headquarters.

"Senior brother, you haven't slept all night again!" Huang Qiaoyun came to the bunker, looked at Bai Shujie with bloodshot eyes, and said angrily: "I went to see the master the day before yesterday, and her old man said that I couldn't do anything, and I couldn't even take care of one person." If you continue to look like this, she will be ready to go down the mountain. ”

Bai Shujie shrugged: "I want to sleep too, but will the little devil agree?" It doesn't matter, as long as you can break this round of attacks of the little devils, you can calm down for a few days. ”

"Report: Commander Zhang Bingyang just called, 8 kilometers south of Jiaodao, and found that the two submarines that surfaced were still unable to move, and it seems that the propellers have completely lost their effectiveness. In addition, Commander Zhang also said that he had already gone to see the submarine of the little devil towed back from the mouth of the Datong River, which seemed to be a Type 171 submarine. ”

Bai Shujie's heart moved, and he suddenly remembered what it was!

The I-171 submarine belongs to the Haida Type 6 A-class. It has a crew of 68 and a safe cruising depth of 70 meters. There are a total of 6 little devils, namely Yi 168, Yi 169, Yi 170, Yi 171, Yi 172, and Yi 173. The first ship was completed on July 31, 1934.

1785 tons of water displacement and 2440 tons of underwater displacement; 9000 horsepower on the water, 1800 horsepower underwater; Two-axle propulsion; The maximum speed on the water is 23.0 knots, the maximum speed under water is 8.2 knots, the cruising distance is 14,000 nautical miles on the water at 10 knots, and the cruising distance is 65 nautical miles at 3 knots.

4 533mm torpedo tubes in the bow and 2 533mm tubes in the stern, carrying 14 533mm torpedoes; On the deck was a 50x diameter 100mm single anti-aircraft gun, as well as a 13mm single anti-aircraft machine gun.

After all, what happens next, let's see how it will be broken down next time.
