While Suiyuan, Laiyuan, Jingcheng, and Taiyuan were all carrying out tense, even thrilling, "Turtledove Plan", the initiator of the "Turtledove Plan", the Zhengzhou side under the command of Song Zhewu, commander-in-chief of the Fourth Route Army, was quite calm.

This is not because there has not yet been an operation here in Zhengzhou, on the contrary, the second division in Lushan should actually be the first of all the units of the Fourth Route Army to start the operation. It is said that Zhengzhou is calm here, because the operation here has been very well disguised and carried out very smoothly.

Because the Fourth Route Army was going to launch an attack from Lushan, Feng Yuxiang's Northwest Army's troops on the first line of Lushan had already assembled on the front line of Yexian and Linying, preparing to storm Luohe with all their might after the Fourth Route Army broke through the positions of Yang Hucheng on the first line of Nanzhao and Fangcheng, and stuck to He Chengjun's main force, creating conditions for Song Zhewu to outflank Wushengguan.

Therefore, in the front of Lushan, which is hundreds of miles wide from east to west, and between the rear and Luoyang, there is now almost no soldier of the Northwest Army.

After receiving the action order issued by Zhang Tao, the cavalry regiment of the Second Division, which cooperated with the Second Division, immediately launched an operation to control the traffic arteries around Lushan, and then all the troops of the Second Division boarded the trucks that had been prepared long ago, and secretly rushed to Huayuankou by car, where they wanted to cross the Yellow River, and some of the food, weapons and ammunition that could not be taken away together were left to Yang Hucheng as planned.

Before Yang Hucheng defected to the central government, there were only four brigades of 20,000 troops, but Yang Hucheng was not a fuel-efficient lamp, he was not willing to just be a commander of the Nanyang garrison, Yang Hucheng recruited troops in the name of supplementary brigades, and established four supplementary brigades in one go. So much so that his troops were not like other troops, and the regular troops and supplementary troops were deployed in a ratio of three to one, or four to one, and even reached an astonishing ratio of one to one.

Of course, Minister of Military Affairs He Yingqin would never agree to him doing this, but now is an extraordinary period, and He Yingqin, including Chairman Chiang, has no choice but to pretend that they cannot see it, but it is impossible for the grain and salary to be distributed according to the actual amount, otherwise other miscellaneous troops will do this, and not only will they not be able to eliminate the miscellaneous army in the end, but will even make them gradually grow, which is very different from Chairman Chiang's original intention.

Therefore, Yang Hucheng's troops' food, weapons, and ammunition have always been very tight, and they have had a difficult time.

Song Zhewu left some food, weapons and ammunition for Yang Hucheng this time, as a gift to Yang Hucheng, and he will get along with this "neighbor" in the future.

Half an hour after the departure of the Second Division, Sun Weiru's brigade arrived at Lushan first, and after informing Yang Hucheng of the situation, it took another half an hour for Yang Hucheng to march into Lushan with the large forces of his remaining seven brigades.

Seeing the food, weapons and ammunition left by Song Zhewu, although Yang Hucheng was very happy, he didn't show much excitement, and even when the cavalry commander of the Fourth Route Army who stayed behind handed over the 50,000 oceans that Song Zhewu gave him in person, he just casually asked the cavalry commander to express his gratitude to Song Zhewu on his behalf.

Yang Hucheng was a very free and easy person, just greeted Song Zhewu's cavalry commander briefly, ordered the troops to load food, weapons and ammunition into the car, and quietly marched north.

According to the plan, the cavalry regiment that remained in Lushan would stay until midnight before it could be withdrawn, the purpose of which was to prevent people from the Northwest Army from breaking into Lushan and discovering abnormalities. Therefore, after the 2nd Division and Yang Hucheng's division left, the cavalry regiment remained on guard in Lushan as usual, as if nothing had happened.

Since the other units of the cavalry division had already arranged alert troops along the way from Lushan to Zhengzhou, although it was a large force of several hundred trucks, it did not cause any strong repercussions, nor did it alarm any troops of the Northwest Army.

After 8 o'clock in the evening, some of the troops of the Fourth Route Army stationed in the vicinity of Liulin and Biyuan Village, south of Zhengzhou, got on the train, and most of them could only rely on foot, and under the cover of the night, quietly went straight to the entrance of the garden. The area from Zhengzhou to Huayuankou is the defense area of the Fourth Route Army, and under the condition that full vigilance has been done in advance, naturally no people from the Northwest Army will be able to discover any suspicious situation.

Since the Zhengzhou Telephone Bureau has always been under the control of Wang Xu's Intelligence Bureau, since the beginning of the "Turtledove Project," all the telephone recipients who made calls to Zhengzhou in the direction of Lushan, Ruyang, and Xinmi west of Zhengzhou have been strictly checked and confirmed, and as long as the answering party is from the Northwest Army of Zhengzhou, they have all been secretly connected to Wang Xu's intelligence office in Zhengzhou, and they will answer in disguise.

The only purpose of this was to completely block the news in this direction and prevent the information of the Second Division and Yang Hucheng's troops from going north from being detected by the Northwest Army in advance.

In addition to Song Zhewu's guard battalion and the organs directly under the headquarters, there was only one regiment of Zhang Tao, even this regiment was also in the name of training exercises in the morning, and it never came back when it arrived at Huayuankou. Now the guards and patrols in the city are all cavalry divisions. Of course, in order not to arouse the suspicion of the Northwest Army, these cavalrymen could not ride horses, and the horses and sabers were hidden on the outskirts of the city.

After Song Zhewu gave the order to act, the Intelligence Bureau headed by Wang Xu, the various offices of the headquarters headed by Mengxi, and the troops stationed in Zhengzhou headed by Zhang Tao were like clocks full of strings, turning nervously and accurately. In the entire headquarters, Song Zhewu is the only "big idler" who has nothing to do.

In fact, Song Zhewu's heart was extremely nervous, the complexity of the "Turtledove Plan" was definitely more complex than a big battle, and the actions of these troops, any problems along the way, could affect his capture of a complete Shanxi, especially the ultimate goal of preserving an intact Taiyuan. For this day, he has been preparing for almost two whole years, and although he tried his best to hide his extreme anxiety, he can completely see his mood at the moment from the full cigarette butts in the ashtray.

Especially Wang Xu, Zhang Tao and Mengxi, the old subordinates who have been following him, can feel the subtle changes in Song Zhewu's inner emotions. Therefore, the latest news from all sides, they will personally go to Song Zhewu's office to report it as soon as possible.

Although Song Zhewu very much hoped to receive reports on the situation of the various armies at all times, the troops in Zhengzhou must also leave Zhengzhou as soon as possible, otherwise, once Yan Xishan and Feng Yuxiang perceive his intentions, it will not be easy for his troops in Zhengzhou to retreat.

At more than 11 o'clock in the night, Song Zhewu has arrived at Wuzhi on the north bank of the Yellow River, and there are sixty or seventy miles to enter Shanxi, which is only more than 130 miles away from Jincheng, an important town in southern Jinnan.

The 1st Division, as the vanguard, had already crossed Wuzhi and rapidly advanced northward, while Song Zhewu and his capable headquarters stopped at Wuzhi. It wasn't that his headquarters couldn't keep up with the march, Zhang Tao left fifty trucks for the headquarters, enough for his headquarters. He stopped here because the radio would not turn on during the march, and he could not get any news that he was most anxious to know, and how could this put his mind at ease.

In the outskirts of Wuzhi, in a dozen tents that had been set up temporarily, Song Zhewu's headquarters was soon running nervously, and several high-power radio stations greedily began to absorb the radio waves carrying countless messages flying hundreds of kilometers away.

"The forwards of Xu Fang and Zhao Fengwu in the south of Outer Mongolia have entered the north of Jin, of which the strikers of the Xu Fang Department have passed the partial pass, and the strikers of Zhao Fengwu have reached the right jade, and the main forces of the two departments can also reach their current position before 3 o'clock in the morning. According to their telegram report, the two divisions had been on the march for eight hours, and the troops were in a good mood, but the horses were tired, and the speed of the subsequent march would be reduced. The forwards of the Xu Fang Department will arrive in Xinzhou before 6 o'clock tomorrow, and the main force will arrive after 10 o'clock; Zhao Fengwu said that he could reach Shanyin and Ying County before eight o'clock. ”

In Song Zhewu's tent, Mengxi was reporting to Song Zhewu and Wang Xu on the progress of the various ministries she had just received.

"Since the 37th Division of Ma Liang stationed in Xinzhou has been transferred by Deputy Chief of Staff Li to the west of Linxian, should the original plan of Xu Fang's troops enter Taiyuan through Xinzhou? I suggest that the forward of the Xu Fang Department still go to Xinzhou as originally planned, and the main force that arrives later will be changed to Jingle, Gujiao, Qingxu to Taiyuan. and left a regiment in Jingle and Gujiao to prevent Ma Liang from counterattacking. ”

Being able to change the plan and make a correct judgment on the spot is not an outstanding place for a combat chief, but it is different to put forward two plans that can attack Taiyuan from the direction of Linxian in Jingle and Gujiao. If Ma Liang had learned that the hundreds of thousands of troops of the Fourth Route Army had entered Shanxi, especially that Taiyuan had been lost, he would not have chosen to attack Taiyuan under normal circumstances. However, because Taiyuan was too important to Yan Xishan, Jin Suijun, and even Song Zhewu, no one dared to guarantee that Yan Xishan would not take this strategy desperately.

Mengxi's timely change of plan is just in case, and Song Zhewu understands that Mengxi knows very well in his heart that he wants to protect Taiyuan and does not want to have a war in Taiyuan. Cautious, delicate, and thoughtful, this is Mengxi's strength, and Song Zhewu appreciates this very much.

However, Song Zhewu did not show his appreciation, he thought that Mengxi still needs to continue to learn and accumulate experience before he can have greater development.

"Yes. Tell Xu Fang and Zhao Fengwu that it is certain that the horses are tired from long-distance running, but time is very important to us, we must rush to the designated place as soon as possible, that is, to run the horses to death, they will all become real infantry, and they will not hesitate! Song Zhewu said lightly.

Mengxi quickly drafted the order, and Song Zhewu signed it after looking at it.
