The poison gas bombs that Inoue Akio secretly carried were a new type of mustard gas bombs that had just been developed by Japan, and they were not many in number, but they were extremely lethal, and these poison gas bombs were only sent to the Wuhan battlefield from Japan. Since the Japanese army's 13th Division used poison gas bombs on a large scale on the Songhu battlefield, which was completely annihilated by Wang Haitao and exposed internationally, and after threatening that the Japanese army would retaliate if it dared to use poison gas bombs again, the Japanese army did not dare to use poison gas bombs again.

When Inoue Akio failed to attack the Great Snow Mountain, he remembered this batch of poison gas bombs. The lethality of these new poison gas bombs was really great, and after Akio Inoue used the poison gas bombs, the defenders on the snowy mountain were defenseless, and a brigade of hundreds of soldiers did not survive, and all of them died on the position. Inoue Akio easily took the position of Daisetsuzan and reached the bottom of the Madang Fort that afternoon.

On the Madang Fort was the chief captain of the Marine Corps, Colonel Bao Changyi, who personally led a brigade of 800 soldiers and more than 200 artillery on the battery. There are strong permanent fortifications for national defense, as well as most of the heavy weapons that Wang Haitao replenished to the marines, which are supposed to be able to withstand the attack of the Japanese army for a period of time.

However, the Japanese army was able to pass through the Changshan position and the Daxueshan position so quickly, which Bao Changyi did not expect. When the alert troops reported that Bao Changyi's Japanese brigade had arrived at the foot of Madang Fortress Mountain, Bao Changyi was still a little incredulous. After confirming the report of the alert troops, Bao Changyi became nervous. Being able to pass through the two positions of Changshan and Daxueshan so quickly and reach the foot of Madang Fortress Mountain, the strength of these Japanese troops should not be underestimated.

In order to be safe, Bao Changyi's telegram for help directly reached Wang Haitao, and Wang Haitao received the telegram very strangely, it stands to reason that it is impossible for the Japanese army to pass through the Daxue Mountain position so quickly, and there must be 800 marines defending there. On the one hand, Wang Haitao sent a telegram to Li Yunheng to inquire about the reinforcements of the 167th Division, and on the other hand, he ordered the 92nd Division to prepare for reinforcements of the Madang Battery.

Although Wang Haitao's 90th Group Army took over the defense of the Jiujiang region, including Qianshan and Taihu Lake, the strength on hand did not increase, and there were only five divisions including the provisional 168th Division. The 90th Army was in Qianshan and Taihu counties, and the 91st Division was transferred to Susong and Huangmei counties. The 92nd Division was in Hukou County, and only the military headquarters and the 93rd Division were in Jiujiang City, and the 2,000 men of the 168th Division were still in the general reserve.

For the Madang Fort, Wang Haitao once again took the 571st Regiment of the 278th Brigade and many armored trucks to Hukou County. Huang Wei's 18th Army was worthy of being a descendant of the Central Army, and in one fell swoop repelled the Japanese 29th Division, reoccupied Jingdezhen, and drove the Japanese back to Zhejiang. Now Jingdezhen is in the hands of the Eighteenth Army, and as long as the Yangtze River defense line is not lost here in Hukou County, it will be safe.

Wang Haitao also didn't expect that Xue Weiying, the commander of the 167th Division, would get into the water in his brain, and he didn't take more than ten kilometers of roads, but went to drill ravines, take small roads, and get lost in the mountains. Here, the 136th Brigade of the Japanese army had already passed under the Madang Fort Mountain, and the 167th Division had not yet come out of the ravine. If he had known this, Wang Haitao would not have stopped in Hukou County, and directly led the 92nd Division to gallop as a battery.

Inoue Akio set up a formation at the foot of Madang Fort Hill and directly launched an attack on Madang Fort. The 136th Brigade of Akio Inoue had only a few mountain artillery, and the others were only Type 92 infantry guns and mortars, which could not destroy the strong fortifications on the forts, so in the afternoon, the three attacks organized by Akio Inoue were all repelled by Bao Changyi.

Bao Changyi, the Japanese army's attack ability, couldn't help but feel a little strange, with the Japanese army's attack ability, the Daxue Mountain position could block the Japanese army for at least a few days, so that the position would not be lost so quickly, and not even a single person who reported the news withdrew. Bao Changyi had a faint bad feeling in his heart. However, Bao Changyi did not expect that the Japanese army would use poison gas bombs, a weapon of mass destruction.

The next morning, Akio Inoue, having launched a second attack without any effect, again used poison gas bombs against the defenders of Madang Battery. Only then did Bao Changyi understand how the Japanese army occupied the position of Daxue Mountain. As a last resort, Bao Changyi could only abandon the first and second positions, and the whole army retreated to the main battery formation. At this time, Bao Changyi only had more than 400 soldiers in his hands, including artillery.

After Bao Changyi sent a telegram to Wang Haitao, informing Wang Haitao of the whole situation, in order to prevent the artillery on the fort from suffering losses, he forced all the artillerymen to withdraw from the back mountain path and the Madang fort, while he himself took the last 200 or so marines to defend their positions. After tearfully bidding farewell to Bao Changyi and others, more than 200 artillerymen withdrew from the Madang Fort from the trail in the back mountain.

Wang Haitao received a telegram from Bao Changyi at the headquarters of the 92nd Division in Hukou County, and his face immediately turned pale. The Japanese army used poison gas bombs on a large scale again, which has touched Wang Haitao's bottom line, if Wang Haitao did not react, he would not be Wang Haitao. Wang Haitao gritted his teeth in the command headquarters and said: "These damn little Japan, on the battlefield in Shanghai, because of the use of poison gas bombs, I completely annihilated the 13th Division. It seems that little Japan has forgotten. In that case, I will teach you some more lessons, so that you may have a better memory. After speaking, a sneer appeared on Wang Haitao's face.

Wang Haitao's expression made Cheng Guangyao, Peng Zhang, and others in the command center feel cool from their backs, and after a while, Cheng Guangyao cautiously asked: "Military seat, what did the telegram from Madang Fort say?" Wang Haitao said coldly: "Madang Fort is lost!" and then handed the telegram in his hand to Cheng Guangyao. Wang Haitao's words surprised Cheng Guangyao, and he hurriedly took the telegram and read it with Peng Gui.

After reading it, Cheng Guangyao already understood why Wang Haitao's face was so ugly, on the battlefield in Shanghai, for the Japanese army to use poison gas bombs, Wang Haitao completely annihilated the 13th Division, Cheng Guangyao also heard about it, and in the later Nanjing Defense Battle and Xuzhou Battle, the Japanese army did not dare to use poison gas bombs again, so Cheng Guangyao did not expect that the Japanese army would use poison gas bombs at this time.

After reading the telegram, Cheng Guangyao asked Wang Haitao: "Military seat, once the Madang Fort is lost, Hukou County will be in danger here, should we strengthen the defense here in Hukou County?" In fact, Hukou County is the intersection between Poyang Lake and the Yangtze River, and it is also the entrance to Jiangxi. The middle and lower reaches of the Yangtze River are divided, with the lower reaches below the mouth and the middle reaches above the mouth.

The economic and geographical status of Hukou is a hundred times more important than that of Madang, but purely on tactical defense, although Hukou has Shizhong Mountain and other west locks Poyang and the Yangtze River in the north, but no matter from the water or land, its danger is worse than Madang by a grade, in the case of limited material and financial resources, after the old Jiang Chongjin built the Madang Fortress, the Hukou Fortress not far away can only be built unsatisfactory.

Wang Haitao understood what Cheng Guangyao meant, but Wang Haitao's answer was something Cheng Guangyao never expected. Wang Haitao replied: "How can the Madang Fort be lost like this? I will not let go of the 136th Brigade of Little Japan, and I will decide the head of this brigade commander!" Wang Haitao's categorical answer made the people in the headquarters feel lifted, and Cheng Guangyao asked with some excitement: "Military seat, what to do below, you can give an order!"

Wang Haitao thought for a moment and said: "First send a telegram to Tang Xiaoshan of the reconnaissance regiment, and ask Tang Xiaoshan to immediately lead the two battalions of the reconnaissance regiment to Madang Battery, and be on standby after arriving tomorrow night." Attacking Madang Battery, the reconnaissance regiment will be of great use. After giving this order, Wang Haitao looked at Cheng Guangyao and the others and said, "Guangyao, you lead the 92nd Division to recapture Madang Fort with me, and leave the 571st Regiment to defend Hukou." Cheng Guangyao and Peng Zhang replied loudly: "Yes, military seat!" After preparing for a day, early the next morning, Wang Haitao personally led all the officers and men of the 92nd Division, as well as all the armored trucks, to live in Madang Battery.

At this time, Wang Haitao had expected that the loss of the Madang Fort was certain, but why the 167th Division failed to arrive in two days was something that Wang Haitao couldn't figure out. Hukou County was only 60 kilometers away from Madang Fort, and the 92nd Division was advancing at full speed and could arrive within 10 hours. When Wang Haitao and the 92nd Division arrived at Pengze County in the afternoon, they not only encountered more than 200 artillery soldiers who had been withdrawn from the Madang Battery, but also encountered the 167th Division, which had just turned out of the ravine and returned to Pengze County.

After Wang Haitao listened to the report of Xue Weiying, the commander of the 167th Division, he was so angry that he was about to kill Xue Weiying on the spot, and was stopped by Cheng Guangyao, the commander of the 92nd Division. Wang Haitao was furious, and dismissed Xue Weiying from his post on the spot and took him into custody, so that he could be sent to the Military Justice Department of the Theater Command in the future for strict handling. Then Wang Haitao appointed Xu Shiming, chief of staff of the 167th Division, to temporarily replace the commander of the 167th Division, and ordered Xu Shiming to lead the 167th Division to recapture the position of Daxue Mountain and cut off the retreat of the 136th Brigade of the Japanese Army.

After the departure of the 167th Division, Wang Haitao also led the 92nd Division to continue to advance towards Madang Fort, and intended to arrive at the foot of Madang Fort Mountain at 8 o'clock in the evening. Soon after Wang Haitao arrived, Tang Xiaoshan also led two reconnaissance battalions to join Wang Haitao. Wang Haitao had already made up his mind to completely annihilate the 136th Brigade of the Japanese Army on the Madang Battery, and would do whatever it took to do so.

The 275th Brigade of the 92nd Division was seriously damaged in the Battle of Yuexi, and Wang Haitao asked the brigade commander Peng Shigui to lead the 275th Brigade around to the northeast of Madang Fort, accompanied by dozens of armored trucks. The 275th Brigade made a feint, and its main task was to intercept the Japanese escape and cover the main attack of the southern troops. The 276th Brigade, on the other hand, launched the main attack on Madang Fort with the assistance of two reconnaissance battalions.
