On the very day that the US task force arrived at Kaohsiung Port, the Japanese reconnaissance submarine operating in Tainan found out the situation of the US fleet. The news was quickly transmitted to the Japanese base camp, and military experts at the Japanese base camp believed that the US fleet had arrived in Taiwan and judged that the target of the landing operation that the enemy would launch again would definitely be the port of Kaohsiung. For this reason, the Japanese army headquarters ordered the commander of Taiwan's defense, Shirakawa Yoshi, to strengthen the defense of Kaohsiung Port. However, the commander of the Chinese dispatch force, Okamura Ninji, did not think so after hearing the news. He believed that the Chinese army had already taken control of the western part of Taiwan, and there was no need to launch another landing operation.

Okamura Ninji carefully analyzed and believed that with Ouyang Jian's strategic vision, the US fleet would definitely go north to blockade Wusongkou, so that the Japanese troops in the entire Songhu area would fall into a catastrophe. The base camp also panicked when it received Okamura's report, and immediately sent a task force to Songhu and ordered Commander Okamura to do his best to secretly withdraw the Japanese troops in the Songhu area. In fact, when Ouyang Jian saw the U.S. fleet, he had an idea in his heart, and his eyes naturally aimed at the Japanese troops in Songhu.

At this time, the Japanese army headquarters in Lushun, the chief of staff of the Japanese army, said: "General, I have sent a telegram to Yanagawa Heisuke to ask him to prepare secretly, and the task force will arrive in 3 days." Okamura Ninji walked a few steps and said, "I'm worried that the enemy will notice it and send fighter planes to attack me. Yanagawa Heisuke was ordered to start a secret withdrawal of troops tonight using merchant ships, cargo ships, and transport ships, and to stop the withdrawal during the day. Yanagawa Heisuke was ordered to move the front-line defense troops first, and the gendarmerie troops in the city did not move. The main forces were withdrawn first, and the military supplies were slowed down. In order to prevent the enemy from detecting it, military supplies and facilities must not be blown up. ”

In a small two-story building in the original British Concession of Shanghai, Zhong Wenjuan, the head of the Shanghai Station of the Military Command, looked at the sporadic crowds on the street. In the past few months, the Japanese army has implemented martial law in the city, and when the Spring Festival is approaching, the Japanese army headquarters has posted a notice, saying that for the sake of Sino-Japanese friendship, martial law will be lifted for three days during the Spring Festival, so that the people in the city can spend three days of lively Spring Festival. However, three days later, the Japanese army headquarters announced that martial law would be lifted until the tenth day of the first month, which surprised Zhong Wenjuan. At present, my cousin Ouyang Jian is leading a large army to fight in Taiwan, is it normal for the Japanese army in Shanghai City to be so "kind"? Zhong Wenjuan realized that the Japanese army must have a conspiracy, but there was no sign that the Japanese army had moved?

Zhong Wenjuan learned about the situation through the undercover agent who broke into No. 76, but still found nothing. The clock is no longer confused, and the traces of the years are engraved on her face, although she is graceful and luxurious, but the whole image can be seen as a middle-aged woman. Due to Ouyang Jian and her special profession, she has never been married, but disguised as the aunt and wife of a high-ranking official in Wang's puppet government. The titular husband, a high-ranking official of Wang's puppet government, has already died, and she plays the role of her widow's wife. A subordinate pushed the door and walked in to report: "Station commander, the 3rd Action Group reports that the Japanese army's military dock has been heavily guarded in the past few days, and I don't know what the Japanese army is doing. ”

"Order the 3rd Action Group to immediately find out the movements of the Japanese troops at the docks." After her subordinates left, Zhong Wenjuan's eyes turned to the sparsely populated streets, thinking about the Japanese army's inexplicable extension of the ban. As an experienced agent, she had a hunch that the Japanese army must be frustrated, but she would not have expected that the Japanese army would secretly retreat. For three consecutive days, her subordinates did not find any clues of the Japanese wharf, and on the morning of the fourth day, she received information that a mixed fleet of Japanese troops had arrived at Wusongkou. Zhong Wenjuan had a premonition that something big was going to happen and did not dare to slack off, and immediately transmitted the information to Chongqing.

At Taiwan's Wanli Joint Command, Chief of Staff Bai Chongxi held a call from Chongqing in his hand and said: "According to the report of the Shanghai Intelligence Station, a Japanese task force has arrived at Wusongkou. The Military Council held that the Japanese had learned that the US fleet had entered the Taiwan Strait with the intention of strengthening the maritime defense of the Songhu area. "The Japanese army reacted so quickly! The air force units in Nanjing were ordered to dispatch reconnaissance planes to find out the situation of the enemy fleet. Ouyang Jian also agreed with the judgment of the Military Committee, believing that the Japanese army sent a mixed fleet to deal with the American fleet.

On the same day, according to the aerial reconnaissance situation, a mixed Japanese fleet stayed in the waters of the mouth of the Yangtze River, which further confirmed that the Japanese fleet was aimed at the US fleet. Ouyang Jian in the joint command said: "The Japanese task force is here, and when we have our hands free to deal with it, we will stage a big drama of shore-based aircraft against battleships." The submarine hunting team was ordered to be on high alert to prevent Japanese attack submarines from entering the Taiwan Strait. "Due to the appearance of the Japanese naval task force, it has invisibly attracted attention, which has played a good shielding role for the secret retreat of the Japanese army.

In the headquarters of the Japanese army in the brigade, the chief of staff of the Japanese army reported: "General, Yanagawa Heisuke reported that there was a small-scale secret retreat for 3 consecutive days, without causing any alarm. It was suggested that the task force should stop at Wusongkou to attract the attention of the enemy and continue to retreat at night. "Agree with Yanagawa Heisuke's suggestion. In addition, Japanese nationals, including merchants, were not allowed to retreat in Shanghai, lest they be noticed by the enemy. Although Okamura was very satisfied with the smooth secret retreat, he was suspicious of the sudden appearance of the US fleet in the Taiwan Strait, and he judged that the US military might abandon the plan of landing in the Philippines and launch a direct attack on the Ryukyu Islands in the next step.

The commander of the Songhu defense, Yanagawa Heisuke, racked his brains to secretly evacuate the Japanese troops from the Wufu defense line and the Hangzhou defense line, and came up with a brilliant idea for this. On the day that the Japanese naval task force arrived at Wusongkou, Yanagawa Heisuke led the personnel of the headquarters to transfer to the battleship. At the same time, he issued an order to order the Japanese defense troops on the front line of Wufu and Hangzhou to carry out night training. In each training, each unit separated part of its forces and secretly retreated, the Wufu defense line retreated from the Yangtze River to Wusongkou, the Japanese army retreated from Jinshan on the Hangzhou defense line, and the Japanese army dispatched transport ships to meet at Jinshan port.

Since there were more than a dozen divisions of puppet army troops on the Wufu defense line and the Hangzhou defense line, this purpose was to deceive the puppet army. On the morning five days after the Japanese task force arrived at Wusongkou, a puppet army division commander in Hangzhou got up early in the morning, washed up and prepared for breakfast. Seeing that the Japanese army was dying, the division commander contacted the Shanghai intelligence station in order to find a way out. The stationmaster Zhong Wenjuan was instructed by the upper hand to accept the surrender of the division commander. Since the front of Hangzhou was the troops of the Eighth Route Army, the Chongqing side ordered the division commander to lie dormant temporarily.

"Report to the division commander, according to the report of the sentry at the city gate, the Japanese army did not return to the city last night!" The division commander was puzzled when he heard this, hesitated for a moment and then picked up the phone. As a result, there was no response on the other side of the phone, and about 20 minutes later, the commander of the puppet army drove to the Japanese city defense headquarters, which was empty, but all the facilities inside were in good order, and there was no trace of mess. Subsequent reports followed, and there was not a single Japanese soldier in Hangzhou. The commander of the puppet army was horrified when he saw this scene and immediately reported it to the Shanghai intelligence station.

The same scene appeared in Shanghai City, and the person in charge of the city's dark arrow appeared in front of Zhong Wenjuan early in the morning. "Stationmaster Zhong, all the important departments in Shanghai City have been replaced by puppet army troops, they received orders at the same time last night, today my people found that there are no Japanese troops in the city, we judge that the Japanese army has fled, this situation has been reported to the Eighth Route Army Headquarters." Zhong Wenjuan did not dare to slack off when she heard this, and immediately ordered her subordinates to inquire about the situation of Hangzhou and Wufu's defense line, and the result surprised her.

The headquarters of the Eighth Route Army received the report of the dark arrow and immediately ordered the defensive troops on the first line of Hangzhou and the defensive troops of the first line of Wufu to immediately march to Songhu. At this time, at Wusongkou, Commander Yanagawa Heisuke ordered the fleet to set sail. In the early morning, the last group of Japanese troops, including important personnel in the city, were safely aboarded, and the retreat mission under his personal command was brilliantly accomplished. Not only did the troops and important personnel evacuate safely from the Songhu area, but some military supplies were also rushed. But Yanagawa Heisuke was still in a gloomy mood, he looked at the gray city of Shanghai and felt bad in his heart, and it was definitely a shame for the Japanese Imperial Army to give up this beautiful city easily.

The puppet army troops on the Wufu defense line and the Hangzhou front line lost their backbone, and immediately produced a multi-bone rice faction effect and collapsed as a whole. The next scene was very spectacular, with the rapid advance of the Eighth Route Army, the puppet army defense departments hung up white flags one after another. Some of the officers, who knew they were guilty, fled in disguise. On the night of the same day, a unit of the Eighth Route Army of the Wufu Defense Line took the lead in entering Shanghai City to exercise military control and prevent chaos in the city. The Japanese army secretly retreated to Songhu, which was beyond everyone's expectations, and it can be said that Okamura Ningji's move was very beautiful.

Ruijin Eighth Route Army Headquarters, in the face of emergencies: "The city of Shanghai suddenly returned to our hands, which caught us off guard. Although it is a pity that the Japanese army escaped, Shanghai, a city integrating industry and commerce, has returned to our hands in its entirety, and its political and economic significance is greater than its military significance. Shanghai is a historic city, with a very complex social environment and a very complex social environment, so we must choose a wonderful person to sit in Shanghai. In my mind, Ouyang Jian is the best candidate, but he cannot be separated from the position of the chief officer of the Joint Command of the Taiwan Strait Campaign. ”

"The transfer of Ouyang Jian will not be agreed to by Chongqing or the United States." Zhu De interjected. "Chairman, I suggest that Chen Yi go to Shanghai. Since he became the mayor of Nanchang, the city of Nanchang has developed very rapidly, ranking among the best in the whole of Jiangxi. Peng Dehuai suggested. I have no opinion! Zhu De agreed. Notify Chen Yi immediately to come to Ruijin! Runzhi took a few steps and continued: "In the future, we will take over large and medium-sized cities one after another, Ouyang Jian's work experience on urban management and work experience has proved to be very pertinent in practice, and I hope that officials at all levels will learn and deeply understand!" ”

At Taiwan's Wanli Joint Command, Ouyang Jian said helplessly: "Okamura, this old fox is keen and cunning, this guy seems to have seen my thoughts." He saved the fate of more than 200,000 Japanese officers and soldiers, and you can see the coastline from the old port to the Luchao port along the Pudong coast of Shanghai, there are dozens of large and small ports, and there are many landing sites to choose from. Moreover, there were no fortifications along the coast at all, and as long as the US fleet blocked the Wusong Pass, not a single soldier of the Japanese army in the Songhu area could escape. To put it bluntly, even without the support of the U.S. fleet, I plan to launch the Songhu Campaign after the end of the Taiwan Strait Campaign. ”

"Brother Ouyang, the sudden appearance of the U.S. fleet was the main reason why Okamura Ninji ordered the Japanese troops in Songhu to retreat. I suspect that he had already planned to do so, and it was the US fleet that gave him a good reason! Bai Chongxi said shrewdly. Yes, Okamura Ninji is one of the few outstanding generals in the Japanese army, and the retreat from Songhu was indeed beyond my expectations. The retreat of the Japanese army in Songhu to the northeast has increased the difficulty for us to attack the northeast in the next step. "Report, the Eighth Route Army headquarters is calling!" Ouyang Jian took the telegram and looked at it a few times and said, "Call back, I have no opinion on Chen Yi sitting in Shanghai!" ”
