When Jiang Bonwu arrived at the headquarters, "Sun Yuesi finished lunch. He planned tactics on the map.

"Huwu, you are coming just right. I was about to send someone to find you. Just now, the Air Force sent information. The movements of the Japanese army in Yizhou were suspicious. Maybe they would attack the border soon. You go back and set up a floor plan and urge the officers and soldiers to step up the construction of fortifications."

Seeing Jiang Huwu coming, Sun Yue hurriedly called him to the side of the map. "Ding Gui a few words, then asked about the origin of the officers waiting outside the door, and asked about the situation, and called the intern officers into the house and made a speech. Then he called a staff officer and beat them to the army.

The intern officer left the headquarters with his feet. Zhang Guoping walked into the headquarters, exchanged a few greetings with Sun Yue, and urged Jiang Lingwu to lead him to the position to take a look.

When Jiang Xiewu and Zhang Guoping arrived on the position, the officers and soldiers had already started working. Now the trenches and anti-aircraft shelters have been dug almost all. The rest is to lay barbed wire in front of the position and lay mines.

Zhang Guoping was very satisfied with the construction of the position. After inspecting the position, he did not rush to leave, but stood on the bank of the Ji River. He held up his telescope and looked southeastward.

There is the place where the Grain River flows into the Yalu River. Zhang Guoping is waiting, waiting for a fleet to come.

At about two o'clock in the afternoon, the fleet finally came. The gunboat "Chuguan" was headed, followed by several torpedo boats. It was the "wild duck army" that was swimming on the Yalu River.

"Wild Duck Force. The retreat from the Yalu River to the Class River is to provide fire support to the defensive forces. The class river is shallow and large Japanese warships cannot enter. However, shallow water gunboats like the Chuguan can wield firepower and enter the Class River. They can avoid direct contact with the Japanese army, which is conducive to preserving their strength. Once mines are laid at the mouth of Jihe River, the Japanese Navy will not be able to send gunboats to Jihe River. Zhang Guoping saw the ships of the "Wild Duck Force" sailing towards Zhenjiang Fortress in the telescope, so he sighed with a sigh of relief. He was originally worried that the fleet might be intercepted by Japanese artillery fire on the Yalu River, but now it seems that the fleet's strength is not damaged, especially the gunboat "Chuguan", which cannot face large warships head-on. However, in shallow water war zones like Jihe, it can exert enough combat power to provide strong fire support to the army.

The main reason why the Yalu River national defense line did not spread along the Yalu River line, but retreated dozens of miles was that the Japanese Navy was worried that the warships were sailing into the Yalu River to provide artillery support to the Japanese army and establish a formation far away from the Yalu River. In order to fully exert their own firepower and weaken the enemy's firepower, the General Staff General chose the area of ​​the building to build a base in the lower reaches of the Ji River far away from the Yalu River. It was also coming out of this consideration.

Compared with the navy's heavy artillery, the army's heavy artillery is inconvenient to move. It is easy to be attacked by the air force. Unless the Japanese army can seize air supremacy, this line of defense is an insurmountable obstacle for Japanese ground troops.

Of course, Zhang Guoping was not without concerns. If the Japanese army had too strong troops, it was still difficult to defend this line of defense, because so far, the total Chinese troops on the Yalu River national defense line had less than 20,000 people, and half of them were the Revolutionary Guards or local troops. The combat effectiveness was poor. As for the independent cavalry division under Zhang Guoping, its main force had been transferred to Phoenix City and was preparing to participate in the decisive battle on the Liaodong Peninsula. Now Zhang Guoping can command only one cavalry regiment and a small number of Zhang Zuoshuang's cavalry, and the rest were infantry troops.

For this reason, Zhang Guoping was very happy about the arrival of the "Wild Duck Force". Although this naval squadron is weak, as long as it enters the Grade River, this force can play a role, because the Yalu River defense line is distributed on both sides of the Ji River. Relying on this water route, the Wild Duck Force can provide firepower support to most positions on the defense line very conveniently. This is the mobile turret on the water.

Of course, the "Wild Ducks' troops are still insufficient in heavy firepower. If they want to defend the Yalu River national defense line, they must strengthen the army's heavy artillery fire. Zhang Guoping has applied to the General Staff to transfer two train guns from the Liaodong battlefield to at least defend the southern part of the national defense line. As long as any key position on the national defense line has not been lost, even if the Japanese conquered the defense line, they cannot continue to advance because their logistics line is exposed in front of the attack position of the Zhongzhang team.

Train guns alone are not enough. Heavy howitzers must also be replenished to the frontline troops as much as possible, and the number of bombers in the air force must also be strengthened. However, a decisive battle is currently being planned on the Liaodong battlefield. Zhang Guoping does not have much confidence in how many weapons and forces can be added to the Yalu River frontline. He can only try his best to do his job well, at least to arrange the positions first.

Zhang Guoping called a staff officer, stood on the bank, sent a signal to the "Wild Duck Force". When the "Chu Guan.com arrived here, he stopped the car and threw cobalt on the river, put down a single board, and carried the captain and others to the shore. He contacted Zhang Guoping. From this moment on, the "Wild Duck Force" directly swept the Wulu River War Zone, and Zhang Guoping pointed directly at him.

This was not the second time that Jiang Xiewu saw the "Wild Duck Force" warship. In fact, when Datian troops retreated from the Yalu River a few days ago, the "Chuguan" provided fire protection for the troops on the river surface. It was the existence of this naval detachment that the Japanese army troops had not crossed the Yalu River for a long time. After only a few tentative attacks of a scale, they retracted back to the left bank of the Yalu River.

After the captain of the "Chuguan" contacted Zhang Guoping, he followed Zhang Guoping to the Zhenjiang Fort Command. Jiang Huwu stayed on the position and continued to command the troops to set up positions. Since the front was the Grade River, the position of the position was very similar to that of Anzhou North City. Jiang Lingwu could completely optimize the position based on experience, and absorbed the Anzhou defense war scramble. Jiang Yuwu specially buried landmines on the river beach on the other side and equipped searchlights on the position. Once the Japanese army launched a night attack, the troops could effectively project firepower and suppress the Japanese army on the beachhead position.

When the sun was so busy that the sun was far west, all the barbed wire mesh in front of the position had been laid out. However, Jiang Lingwu did not ask the troops to stop construction immediately, but urged the officers and soldiers to continue to strengthen the trenches and build more anti-aircraft shelters. The Japanese artillery fire in Anzhou really impressed Jiang Langwu.

Just as Jiang Lingwu's order was conveyed, a Chinese Air Force reconnaissance plane flew over the Yalu River and flew over the Zhenjiang Fort position at a low altitude, which immediately aroused the interest of the officers and soldiers. Many people cheered and jumped on the position, waved the engineering tools in their hands, and signaled to the plane.

Jiang Bangwu also raised his head and looked at the plane. He could see the pilot and the machine gunner. The pilot was flying the plane seriously. However, the idle machine gunner raised his right hand and greeted the army officers and soldiers on the ground.

Jiang Xiewu smiled. In his opinion, in the Battle of Anzhou, the Chinese air force performed well and persisted until the last moment of the battle. If it weren't for the fight of the air force, Anzhou wouldn't have held on for so many days. Moreover, it was the lack of oil and ammunition of the air force that ultimately led to the Japanese artillery dominance.

Now, a field airport is built in Tuchengzi in the north, with sufficient logistics supply. It is conceivable that once the Japanese army crosses the Yalu River to attack, the Chinese air force will surely show their unique skills again.

Of course, Jiang Huwu didn't know that this Air Force reconnaissance aircraft brought an important piece of information to the Yalu River War Zone, and this information directly prompted the General Staff to adjust the combat plan.

The information was fed back by the General Staff to the Zhenjiangbao Command that night, and then Deputy Commander Sun Yue immediately conveyed the order, and all the troops were transferred to level 1 combat preparations.

The reason is very simple, because in the Dadonggou waters southeast of the Yalu River Estuary, the Air Force's reconnaissance planes showed traces of the Japanese Combined Fleet. In addition to the main force of the Japanese Combined Fleet, the reconnaissance pilots also found a large number of Japanese merchant ships and freighters. All signs indicate that the Japanese army is about to drive landing operations in the Dadonggou. Some Japanese warships have entered the Yalu River Estuary and are moving upstream from the river. The Yalu River Battle is about to begin.

Just as the defenders of Zhenjiang Fort were grinding their fists, a huge fleet was landing in the estuary of the Yalu River, in the Dadonggou, densely covered with shallows and reefs.

The Japanese Navy Marshal Hirahachiro Togo was commanded and landed. At this moment, he was sitting on the flagship "Hanoi" battleship, standing on the open-air bridge in the night, looking towards the direction of Daitogou with a telescope.

Togo Hirahachiro, Dadonggou is not a strange place. It was here that the Beiyang Navy of the Qing Dynasty and the Japanese joint fleet broke out a large-scale naval battle. At that time, Togo Hirahachiro served as the captain of the "Rang" protective cruiser with the rank of Navy Colonel and participated in that naval battle. It was during that naval battle that Togo Hirahachiro truly witnessed the power of the ironclad ship, and it was through that naval battle that Togo Hirahachiro truly became a fanatical believer in the "big ship and giant cannonism".

At that time, the two iron armored ships of the Qing Dynasty, "Zhenyuan Dingyuan", were the most domineering in the naval fleet. The ship guns were large in diameter and thick in armor. In the Dadonggou naval battle, the Japanese joint ships believed that this had suffered a lot. During the entire naval battle, the two iron armored ships were attacked by the Japanese warships with concentrated firepower and their hulls were scarred, but they never sank. This gave the Japanese Navy a strong stimulation. Since then, the direction of the Japanese Navy is "big ships and giant cannons"

Now, the battleships and battlecruisers of the Japanese Navy are already strong enough to look down on the Far East. In contrast, the strength of the Chinese Navy's surface ships is still weak and the submarine forces caused great trouble to the Japanese fleet.
