In order to cooperate with the entire combat operation of the Japanese army in North China, it has been half a month after the fierce fighting in the second phase of the battle. The first time in four or four years that the Japanese 6 Navy implemented in the direction of Qikou w.81zw.com Chinese the first time in four years, and it was also the last large-scale operation of the Japanese army in the entire World War II. The sea off Qikou was full of Japanese fleets, as well as transport ships ready to board 6.

Just when the deputy commander-in-chief commanded the main force of the Shanxi-Hebei-Shandong-Henan Military Region and launched an attack on the whole line against a division of the Japanese army that was rushing towards Huguan. On the coastline of Qikou, a few hundred kilometers away from Linxian, the first batch of shells of various calibers from 356 mm to 120 mm of Japanese naval ships had already fallen.

With heavy artillery fire and constant correction by the school-firing planes hovering over Qikou, the Japanese Navy carried out a fierce artillery bombardment on a target that could be reached along the Qikou line. The huge explosion sound on the Qikou line resounded through almost the entire Bohai Bay. After half a month, the direction of Qikou ushered in an earth-shattering artillery fire from the Japanese Navy. Only this time it was no longer the bluff of the Japanese Navy, but the real wolf came.

However, compared with the twists and turns of the southeast battlefield in Jin, the battle on the front line of Qikou seems to be a little too step-by-step. Maybe it was the first few shellings, and a lot of shells were wasted, but nothing useful was found. Therefore, although the Japanese army covered a lot of troops this time, it was dominated by destroyers and other anti-submarine and air defense ships.

The large ships were dispatched with only three battleships, a heavy cruiser, and an old armored cruiser, plus two light cruisers. However, in consideration of the Navy's current valuable warships and the possible air threat posed by the enemy, the Japanese Navy not only transferred the 6 base air forces that had been transferred to the Shandong battlefield to serve as air cover for the 6 operations this time.

He also ordered a naval aviation training team stationed in Lushun to set aside a part of the Zero Combat to serve as an escort. The battleship Yamato and the two battleships of the Fuso-class class, which had previously flaunted their might in Bohai Bay, as well as the aircraft carrier group that had been dispatched to cover these warships and bomb the coast of Bohai Bay, did not appear this time.

The 6th Army's 6 Deng 6 operation has not been launched for a long time, but the navy cannot leave all the large and medium-sized ships on the mainland, and cooperate with the 6 Army Deng 6 operation, which does not know when it will be launched. Bayi Novel Network w one w said w eight. Eighth 81zw.com not to mention the fact that under the tactical siege of US submarines and wolves, a large number of transport convoys have been sunk, so that the current fuel reserves of the Navy in the mainland have been in a dilemma, and the fuel reserves in the mainland are declining almost every day.

Large and medium-sized ships are oil tigers, and the fuel required for each sortie is astronomical. The first two shelling of Tianjin and Qikou did not achieve any results, but wasted the navy's precious fuel in vain. Although the 6th Army dispatched two divisions in one go this time, the Navy is really reluctant to have precious fuel reserves at the moment, and it will continue to play with the 6th Army.

Therefore, although the navy dispatched a large number of destroyers, transported six troops of the six armies, and undertook anti-submarine and air defense, only eight large and medium-sized ships were dispatched. These eight ships were only transferred from the fleet that was originally scheduled to be transferred to Taiwan because the navy gave the Sixth Army some face.

As for the Yamato, which is considered by the Navy to be the treasure of the town, the last time it wasted hundreds of 460 mm naval shells, as well as the 460 mm naval gun barrels that were precious to the Navy, their service life was reduced due to excessive wear, which made the top brass of the Navy Province half to death. This time, no matter how the 6th Army does its work, the Navy will no longer agree to dispatch.

What are you kidding, the Yamato ship is used for a decisive battle with the Mi Ying ghost beast battleship, not for your 6th Army as a battery. The last dispatch was already a great face-saving for the 6th Army, and this time I want the Navy to waste precious resources and charge for you, so don't even think about it. Not only did the battleship Yamato not sort, but even the battleship Nagato did not sort.

So this time, although the navy also dispatched three battleships, as well as a heavy cruiser plus an old armored cruiser, plus two light cruisers to provide fire support, it was considered sufficient. But these three battleships are undoubtedly old-fashioned, and even the old Kongo-class, and the two battleships that still exist at present have not been dispatched.

In addition to the fact that fuel is precious, it is simply not wasted. The Navy even believed that the enemy did not have a single combat ship or a large-caliber shore gun anyway. For enemy bomber groups with only aerial bombs, a more flexible and maneuverable destroyer is more suitable.

However, although the navy did not dispatch too many large ships, it also mobilized a number of ships from the mainland and Taiwan. In addition to the four first-class transport ships, eleven second-class transport ships were dispatched. And dispatched almost all the destroyers and anti-submarine ships on the mainland to escort the 6th Fleet.

Of course, off the coast of Qikou, the Japanese Navy, which is very uneasy about this place, has swept countless mines before, but this time there is no need to make a big effort, so this time it did not carry minesweepers except for submarines. It's just that the Japanese Navy doesn't know that the deployment of the Anti-Japanese Union along the Qikou coast this time is different from before, and there were really no mines before.

However, this time, not only were mines laid off the coast of Qikou, but also the location of the mines was carefully studied and designed. After the mines arrived, Du Kaishan did not hurry, and hurriedly deployed these mines, which were extremely valuable to the Anti-Japanese Federation, to the sea off Qikou.

Instead, based on the experience of the last Japanese shelling of Qikou, the minefield was deployed more than 20 kilometers away from the coastline. Moreover, the location of the mine-protected area has also been carefully designed, and it has been deployed at the position where the Japanese battleship dropped anchor and opened fire last time. Du Kaishan valued the battleships of the Japanese army, and as for the destroyers escorting the escort, his own cannon group could still deal with it.

There is no way, the previous experience told Du Kaishan that if he did not solve these large ships with a range of more than 30 kilometers and large-caliber naval guns, he would not be able to reach the range at all, and it would be difficult for him to destroy the cannon groups of these battleships with thick skin and flesh, and he would not be able to pose any threat to the Japanese 6th Fleet at all.

If they don't find a way to kick them out of their fire support groups as much as possible, the artillery fire of these large ships at a position of more than twenty kilometers from the coastline will be enough to destroy their own artillery positions. A 356 mm caliber shell is simply not something that his artillery positions can withstand.

However, relying solely on dealing with third-line operations, the aviation forces that are already very tight in force are far from meeting the needs. Therefore, when he laid mines, he adopted various methods to wield the maximum power of these mines as much as possible. Even if we can't blow up and sink a few warships, we must find a way to drive them out of Bohai Bay.

As for whether the large ships of the Japanese Navy will continue to be stationed in the previous position when providing fire support, Du Kaishan is quite confident. Although he had never dealt with the Japanese Navy, he was very familiar with the Japanese Sixth Army and had a deep understanding of the rigidity of the Japanese.

The Japanese naval fleet opened fire at that position for half a day last time without encountering any trouble, and this time it will definitely continue to be stationed in that position. Moreover, the water depth on the coast of Qikou is limited, and there are limited places for large ships to be stationed. In addition, before the Japanese warships were dispatched, the Japanese Navy's minesweepers always stopped at those positions, constantly carrying out surveillance and minesweeping activities.

Although these minesweepers were transferred after the Japanese naval fleet completed its assembly, it is almost certain. This time, the large ships of the Japanese Navy must have fired at the same position as last time. However, in order to let the Japanese Navy be recruited, Du Kaishan was not completely passive waiting, he still took certain measures.

At the same time, after the Japanese naval fleet completed its assembly in the waters off North Changshan Island and sailed westward into the Bohai Bay. In accordance with Du Kaishan's request, the air force secretly dispatched more than a dozen B24 bombers, and when the Japanese Navy was pouring shells on the Qikou line, they secretly laid a layer of mine nets in the Lao Tieshan Waterway, which they had to pass through to return home.

Although these mines can only be passively waited for, and cannot be actively attacked, how much role can they play? Du Kaishan, who has no understanding of the Navy and has always paid attention to taking the initiative, is not clear. However, judging from the charge of these mines, Du Kaishan believed that even if he waited passively, it would pose a certain threat to the Japanese Navy.

A few hundred kilograms of high-explosive ammunition will surely make the Japanese Navy drink a good pot. And for Du Kaishan, this is also a helpless choice. There is no way, he does not have the ability to take the initiative. If you want to play brilliantly, you can only use your brain more and use the means that you can use. And what the effect is, at least now he is also confused.

These mines laid by Du Kaishan were urgently manufactured by the Anti-United Nations Arsenal, and they are also the only mines currently available to the Anti-United Nations. It is the M-26 anchor mine that the Anti-Japanese Union exchanged from the Soviets after using some new technology, as well as the KB anti-ship battery tentacle mine technology, the products copied by itself and the finished products provided by the Soviets, as well as more than 400 magnetic mines given by the Americans.

The reason why it was not deployed before was because the anti-union mines had just been copied. The Soviets offered too little in quantity, and what the Americans promised has not yet arrived. And when the war was raging, the Anti-Japanese Federation itself did not have spare production capacity at all to carry out large-scale assault manufacturing.

Although the Anti-Japanese Union asked the Americans to provide a batch of mines before the war, the Americans were very slow to move. Halfway through the battle, 500 magnetic mines were transported. Coupled with some of the samples provided by the Soviet Union and a batch of mines urgently produced before the Anti-United Nations War, this totals more than 3,000 mines, which is already the only stock of the Anti-United Nations.

Deployed too close to the coastline and too early, they could only be swept away by the Japanese Navy's minesweepers one by one, and did not play a great role, but wasted the precious mines. For these only weapons that can be deployed in the sea, Du Kaishan is a precious matter. In order to make good use of these things, he racked his brains, just to let these key weapons play the greatest role at critical moments.

After receiving the batch of mines sent from the rear, Du Kaishan considered it several times, and under the guidance of the commander of the Bohai Naval Region, he deployed the anchor mines and some magnetic mines off the coast of Qikou, where the most powerful battleship was deployed when the Japanese Navy bombarded Qikou last time. When laying mines, in order to achieve the greatest concealment possible, all wooden boats are used to manually lay mines at night.

The minelaying was carried out only at the time when the Japanese Navy began to assemble on North Changshan Island. In order to avoid the Japanese fleet that had been patrolling the Bohai Bay, and to complete the laying of these mines on the only night before the arrival of the Japanese fleet, Du Kaishan also tried his best to lay mines.

Fortunately, several Japanese Navy patrol ships in the Bohai Bay threaten the valuable warships of the Navy in order to prevent the US Navy submarines, which have infiltrated the waters between the mainland and North China, as well as the Bohai Sea area, which are becoming more and more active. The Japanese warships left behind in the Bohai Bay all escorted the sea area of North Changshan Island, which left Du Kaishan with a night to lay mines.
