In the past few days, there have been urgent reports every day, Jiaxing is gathering heavy troops, a large number of ships are heading north from Ningbo, and the latest news is that enemy ships have arrived in the waters of Shanghai, and the pace of war is getting closer and closer.

Baoshan City, in addition to the soldiers, there is no one who has been left behind, the houses are also broken and scattered, according to Wang Feng's order, it is not hesitated to demolish Baoshan City into ruins, after the war, it will be re-planned and built according to the requirements of modern cities, paved asphalt roads, build sewers to reserve various network management space, and even if there are conditions, tap water, every household uses a private toilet, on the one hand, to create a model demonstration city, on the other hand, to accumulate experience for the future reconstruction of Nanjing City.

With the city as the center, the ravines are vertical and horizontal, and according to some large building complexes, irregular bunkers have been constructed, standing on a high place, looking at the Baoshan City with a greatly changed appearance, Sheng Xuanhuai couldn't help but say: "Wang Feng, this is what you call the Baoshan defense line?" But I have a question, if the British army breaks through the mine array we have laid and lands on the shore and does not come to attack Baoshan, but leaves a part of the troops to guard it, and then attacks Suzhou or other cities with heavy troops, then you are not cocooning yourself? ”

Before Wang Feng could speak, Yang Shuijiao had already lost an idiotic gaze: "The British army can't have an advantage in strength compared to us, how many people can he leave to guard?" If there are fewer people, it will not work, and if there are more people, the troops used to break into the interior will be affected, don't you forget, we only dispatched half of the troops, is the other half all decorations?

Besides, if he divides his forces and advances, then we can clear the walls, and the armies that defend the cities will only have to resist for a few days, and we will cut off his supply lines with the main force, and then close the siege, what can he do but surrender? We even took advantage of the emptiness of his remaining ships. Take advantage of the night to seize his ship!

If this is the case with the British army, then I can only say that his commander is either blind to nobody. Either that's stupid! ”

"Oh, Sister Shuijiao. Teachable! Sheng Xuanhuai's face flushed, and he replied in a sneering manner.

Wang Feng was also appreciative, and said: "Yang Shuijiao, I really can't see it, you still have two more moments!" ”

"At that time, four years ago, when the Jintian Uprising, this girl was only fifteen years old, and she had experienced dozens of battles. How can this arrangement not be seen today? Yang Shuijiao snorted twice, his eyes glanced around, but at this moment, he stretched out his hand and pointed sharply: "Look at the river!" ”

More than a dozen beacons standing on the sandbar in the distance rose like a relay and pierced into the sky, indicating that the combined fleet had entered the mouth of the Yangtze River.

Sheng Xuanhuai was inexplicably a little nervous, and hurriedly said, "Wang Feng, let the soldiers arrange the mine array." By the way, the personnel on the beacon must also be withdrawn in time. ”

Wang Feng waved his hand and said, "Don't worry, it's already been arranged." Personnel on the Beacon will participate in mine-laying. ”

"Oh!" Sheng Xuanhuai nodded, hurriedly picked up the binoculars, and looked nervously at the lower reaches of the Yangtze River.

Xie Anbang is from the Fujian Xiaodao Society, is the commander of the Second Brigade of the Third Division of the First Army, and the county magistrate of Baoshan County. Immediately he screamed: "Brothers, according to the predetermined plan." Blackwood! ”

"Yes!" One by one, figures rushed to the fishing boats moored on the shore, and the full number of combat personnel of the Second Brigade was 2,700. Each boat carried six people, for a total of four hundred and fifty minelaying boats. Of these, 150 were distributed in the secondary channel separated by the sandbar, so that 300 entered the main channel.

Soon, the ships according to the river staggered, slowly rowed downstream, today's mine is not the most primitive wooden box square mine, but improved to the iron shell round mine, its sealing is better, the ability to resist wind and waves is stronger, the power of the explosion is also greater, but unfortunately, due to the tight time, the mine still relies on trigger detonation, the rest such as sound, water pressure, magnetism and other detonation methods, R & D personnel are still in the theoretical learning stage.

However, in addition to drifting mines, the army is also equipped with a considerable number of anchor mines, that is, through guò cable connection mine anchors fixed at a certain water depth, anchor mines in the modern sense have the function of automatic depth fixing, can control the depth of mine laying, and the anchor mines of the Democratic Alliance Army are not up to for the time being, so they can only use the most stupid method, that is, to find out the water situation in advance, draw a topographic map of the bottom of the river, and cast anchor mines of different depths according to the coordinates according to the terrain in wartime.

Fortunately, the area that needed to be mined was only the river surface around Baoshan, and after a whole year of exploration, I finally got a rough idea of the situation at the bottom of the river.

At present, in addition to the earliest batch of drifting mines, the later production of mines has been modified to electrolyte trigger, the five antennae on the mine body is the key to detonation, each tentacle is composed of a zinc cup, a carbon rod and a glass tube filled with electrolyte, the antennae is equivalent to a dry battery, the zinc cup is equivalent to the zinc skin of the outer layer of the battery, the carbon rod is similar to the carbon core with a copper head on the top of the battery, and the electrolyte in the glass tube plays the role of a viscous body in the battery.

When the tentacle is bent, the glass tube is broken, the electrolyte flows between the zinc cup and the carbon rod, a chemical reaction occurs, and an electric current is generated, and the current is transmitted to the electric lightning ~ tube, and the electric lightning ~ tube detonates and detonates the mine.

Wang Feng did not believe that the British army would not take into account the factor of mines, so he ordered the Ordnance Bureau to make great efforts to develop anchor mines, drifting mines only play a role in covering people's ears, the real killer is still anchor mines, but because they can only be placed in a fixed place, so the minelaying boats should slowly row downstream, leaving room for mines, and each boat is equipped with a topographic map of the bottom of the river to mark the depth of the water.

"Brigade Commander Xie, here, the foreigners are really prepared!" Xie Anbang, as the brigade commander, personally boarded the ship to command, and at this time, a soldier reminded him.

Across the river for about ten miles ahead, there are gradually the shadow of sails, which can be seen clearly in the telescope, they are all small fishing boats with fences at the front, which are clearly minesweepers, Xie Anbang immediately shouted: "The whole army hovers, listen to Lao Tzu's order, and release mines!" ”

Flags were waved out in all directions, and the soldiers rowed their oars upside down, so that the boat could stop.

In Baoshan City, because of the height of the station, so to see farther, behind the dense minesweepers, is the British battleship formation, Sheng Xuanhuai couldn't help exclaiming: "My God, the British have brought another big guy, bigger than the Hermes last time, but you see, his cannon muzzle has become smaller, I don't think it will reduce the power, it is likely that a breakthrough has been made in technology, Wang Feng, you have to be careful!" ”

In addition to the flagship Duke Wellington, there are four frigates with a displacement of about 1,500 tons, and the rest are all small steamers, with a visual tonnage between 200 and 400 tons.

This is obviously a temporary collection from the area of Hong Kong and Guangzhou, in fact, it is easy to understand, modern naval warfare is no longer the ancient era of thousands of warships dispatched at every turn, if 50 come, even if all are the lightest frigates, with Britain's national strength can not bear it, just like the Beiyang Naval Army, there are only a few main warships, and the rest dozens are all small and medium-sized ships.

According to Wang Feng's guess, these four frigates are likely to be requisitioned from Singapore, Indonesia and other places, after all, Britain's mainland is in Europe, and the whole of Europe is in a state of chaos, Britain must ensure the safety of the mainland and the Atlantic route, and there will be no more than ten large ocean-going warships distributed above the frigates in the Asia-Pacific region.

It's just that although there are only five main warships, the red single ships are mixed in the small steamers, and there are also troop transport merchant ships behind, and hundreds of ships are overwhelming, as far as the eye can see, which can easily make people feel invincible.

The current Democratic Alliance forces are not capable of confronting Britain on the water, Wang Feng just swept the telescope back, and carefully observed the Duke of Wellington, compared with the guns on the Hermes, the barrel of the Duke of Wellington is more slender, and there is an extra baffle in front, which makes Wang Feng almost think that Britain has developed rapid-fire artillery, but when he looks at the chassis, he is relieved.

The key to rapid-fire artillery is the retraction and retraction machine, which can make the chassis of the gun use its own recoil to recover to its original position after firing, saving the time of resetting and re-aiming, thereby improving the rate of fire of the artillery, and the Duke of Wellington still uses the rack back technology, that is, the gun body of the gun is connected to the gun mount through the guò trunnion, and the gun carriage bears the recoil, and a certain displacement will occur when the gun is fired, and it needs to be reset again.

Although the rate of fire has not increased, the ratio of a thinner caliber to a larger diameter indicates that the firing range will be greatly increased, Wang Feng couldn't help but scold: "Damn, where did the British get a Big Mac?" ”

"Huh?" Sheng Xuanhuai was immediately surprised: "Wang Feng, I find that you sometimes speak very strangely, such as the Big Mac, the giant, the huge, the overlord, the domineering, generally speaking, the huge also seems domineering, just like the Duke of Wellington in front of you, don't you think it's domineering?" But the Big Mac is literally understood as huge and not domineering, which makes it difficult for people to understand, can you tell me why? ”

"Huh?" Yang Shuijiao's eyes also lit up, and she looked at Wang Feng with a burning look, didn't the Big Mac come out of Wang Feng's mouth once or twice, she didn't think about it before, but after Sheng Xuanhuai reminded her, it was indeed very problematic!

Wang Feng was annoyed and angry, and said forcefully: "Nothing means incomparable, it doesn't mean no, Big Mac is huge and incomparably domineering, do you understand?" I said that you don't care about the enemy at the moment, why are you chewing the words? This attitude of yours is very problematic, you turn your head back, the British minesweepers have accelerated, look good! ”

"Nothing? Hehe, this is the first time I've heard of it. Sheng Xuanhuai touched his head, looked at Wang Feng very strangely, and then put on the binoculars and looked over. (To be continued) R466
