Su Zuxin and Tang Longzai followed the direction of Tang Renxin's finger and looked at the sand table, Tang Renxin pointed to the two mountains of Natong Mountain and Wubei Mountain between Chongzuo City and Jiangzhou Town. The ratio of the sand table is 1,000 to 1, but it also clearly shows the type and landform near Zhengzuo City. On the sand table, Jiangzhou Town is in the direction of Chongzuo City, and it is not far from Jiangzhou Town to enter the mountains.

The first mountain is Natong Mountain, starting from Natong Mountain, a mountain road zigzags through the mountain, until it crosses the back of the house, and then it comes to the south gate of Zhengzuo City. The trail is eight kilometers long and well-groomed, with yard trucks, heavy artillery and combat vehicles passing. Su Zuxin and Tang Longzai looked at the sand table for a while, and Su Zuxin seemed to see a little fame.

After a while, Su Zuxin said to Tang Renxin: "Deputy Army Commander Tang, you are going to use this mountain road to attack the 16th Division!" Tang Renxin smiled and said, "Chief of Staff Su, I mean this. You see, if we put the Japanese army into this road, stop the Japanese attack at Yabei Mountain, and then cut off the Japanese retreat at Natong Mountain, then we may be able to eat this Japanese army. ”

When Tang Renxin said this, Tang Longzai suddenly said: "Deputy Commander Tang, you are going to close the door and beat the dog!" Tang Longzai's words made both of them laugh. Then Tang Renxin said everything in his heart. After finishing speaking, Su Zuxin thought for a while and said: "Deputy Army Commander Tang, this plan of yours, it is not enough to use only one division of the 211th Division, in my opinion, the 90th Division and the withdrawn 210th Division must be used to ensure that nothing goes wrong." ”

Tang Longzai interjected: "Chief of Staff Su, you also think too highly of Little Japan, just with the 16th Division, with our 211th Division, I will guarantee that I can take them down." Su Zuxin smiled and said: "Commander Tang, don't underestimate the enemy, the rabbit is in a hurry and wants to bite people, not to mention nearly 40,000 Japanese troops?" Tang Renxin also said: "Chief of Staff Su is right, the lion fights the rabbit and still has to use all his strength, let alone 40,000 Japanese troops? I immediately put together a battle plan and reported it to the military seat. ”

Early the next morning, Wang Haitao in Longzhou received the battle plan jointly formulated by Tang Renxin and Su Zuxin. Wang Haitao took the battle plan, compared it with the military map, studied it for a while, picked up his pen, revised the loopholes in the two battle plans, and then wrote: "It is agreed that the front line will implement this plan, and this plan will be under the full command of Deputy Army Commander Tang Renxin." ”

After receiving an order from Wang Haitao to agree to implement the plan and to take full command of him, Tang Renxin immediately began to dispatch troops. The first order was issued to the 90th Division, ordering the 90th Division to reach Wubei Mountain south of Chongzuo City within two days and rush to repair the fortifications. The second order was issued to the 210th Division, which had already been repaired in Zongzuo City, and ordered the 210th Division to lay in ambush and stand by as a regiment along the road from Natongshan to Yabeishan.

The third order was issued to the 211th Division, ordering the 211th Division to hold out in Jiangzhou Town for more than 15 days, to make comprehensive preparations for all troops, and after 15 days, when it received the order to retreat, it did not withdraw to Chongzuo City, but to withdraw to the mountains next to the road, and after the Japanese army marched towards Chongzuo City, it would occupy Natong Mountain and cut off the retreat of the Japanese troops attacking Chongzuo City. After the three orders were transmitted, Tang Renxin selected a suitable point for her, transferred the heavy artillery brigade over, and also ordered the armored brigade to drive outside Chongzuo City and assemble on standby. After these orders were transmitted, the various units of the 90th Army around Chongzuo City immediately went into action.

The first to act, and the first to receive the order, was the 90th Division, and the division commander Tang Yikuan received Tang Renxin's order, and without the slightest hesitation, immediately ordered the whole division to assemble urgently. A division of more than 27,000 men was assembled within two hours, and three hours later, the 542nd Regiment of the 271st Brigade, which was the vanguard of the whole division, had already left its garrison and advanced in the direction of Wubei Mountain, with other units of the 90th Division advancing in a steady stream behind the regiment.

Eighteen hours later, the 90th Division arrived outside Chongzuo City, and the division commander Tang Yikuan let the whole division rest in place, and he took Tang Yiqun and Zhang Lingfu into the city to meet Tang Renxin and Su Zuxin. After meeting Tang Renxin and Su Zuxin, and learning the full content of the battle plan from the two, Tang Yikuan and the three of them also became excited.

Tang Yikuan and the others returned to the troops, left the divisional armored regiment in Zhenzuo City, handed over to the armored brigade for unified command, and then took the rest of the troops straight to Wubei Mountain. When they arrived at Wubei Mountain, Tang Yikuan immediately took Tang Yiqun and Zhang Lingfu to climb Wubei Mountain to observe the terrain. When he arrived at the top of the mountain, Tang Yikuan felt a little chill in his heart. It's not for any other reason, it's that this mountain is not only small but also not dangerous, and it belongs to the kind of mountain that is easier to attack.

However, because of the topography, the road under the house back mountain has also become narrower, one side of the road is against the house back mountain, and the other side is a steep slope more than ten meters high. Tang Yikuan looked at the terrain for a while, and discussed with the two brigade commanders for a long time before making a decision, Tang Yiqun led the 271st Brigade to deploy defense on the back of the mountain, and Zhang Lingfu led the 272nd Brigade to deploy defense on the front of the highway. The division headquarters, the division's guard regiment, and the heavy artillery regiment were stationed in Jinjitun, three kilometers behind the 272nd Brigade.

As soon as the order was given, the officers and men of the 90th Division began to get busy, and the construction of fortifications was a familiar road for the 90th Division, and the important thing was that in order to build the fortifications strongly, it was necessary to transport building materials from the city of Zhengzuo. Tang Yikuan gave an order, and the Heavy Artillery Regiment and the Baggage Regiment mobilized dozens of trucks to Chongzuo City to transport the needed building materials.

After Tang Hongming received Tang Renxin's order, he organized four fully manned regiments, led by their respective regiment commanders, to prepare to go to the designated road section for ambush, but it was not easy to choose the location of the ambush. There was still some time, Tang Hongming sent the division's reconnaissance group out to find a suitable ambush site.

Among these troops, only Tang Longzai was idle, the 462nd Brigade had already blocked the Japanese army in Jiangzhou Town, and the 463rd Brigade's mission of garrisoning Chongzuo City had not changed. However, Tang Longzai considered that he would have to hold out for more than 15 days and that the pressure on Jiangzhou Town was relatively great, so he drew the 881st Regiment from the 463rd Brigade to reinforce Jiangzhou Town, and at the same time, 50 self-propelled howitzers and artillery pieces of the Heavy Artillery Regiment also approached Jiangzhou Town, ready to support Jiangzhou Town at any time.

Li Changwu, commander of the 462nd Brigade in Jiangzhou Town, also received the battle plan forwarded by Division Commander Tang Longzai, and received an order to hold out here in Jiangzhou Town for more than 15 days. Li Changwu also did not expect that Deputy Army Commander Tang Renxin would formulate such a battle plan, but after another regiment was reinforced, Li Changwu was full of confidence in holding Jiangzhou Town for more than 15 days.

Considering the important role that Natong Mountain would play in this battle, Li Changwu ordered the 878th Regiment to climb Natong Mountain, repairing the fortifications on the one hand, and hiding on Natong Mountain on the other. Tang Yu received the order, and immediately took the officers and soldiers of the 878th Regiment who could fight, moved to Natong Mountain, and began to build fortifications. However, these fortifications had to be built relatively hidden in case they were discovered by the Japanese army.

While several units of the 90th Army were operating around this battle plan, the first line of defense defended by the 2nd Battalion of the 879th Regiment was also in danger. The 16th Division of the Japanese Army was indeed a Division A and had very strong combat effectiveness. After Chu Xifeng defended for two days, only more than 200 people remained in a battalion and still had combat effectiveness, and the rest of the officers and soldiers were either sacrificed or injured and lost their combat effectiveness.

The Japanese army never used a large number of infantry to attack, but each time used one or two infantry squadrons to attack, these attacking Japanese soldiers were very good at using the terrain, and the marksmanship was quite good, and the way of attacking was still to use the way of battle group breakout. This way of attacking, with the reduction of the number of defenders, is also more and more a headache for Chu Xi.

After once again repelling the Japanese attack with all his might, Chu Xifeng withdrew to the anti-artillery hole to count the number of people, and this time more than a dozen comrades were sacrificed, and more than 20 people were wounded. Seeing that the number of people was only more than one hundred and fifty, Chu Xifeng also sighed helplessly. At this time, Liu Ergen, the commander of the first company, came to Chu Xifeng and said to Chu Xifeng: "Battalion commander, our people are getting fewer and fewer, do you have to come up with an idea, or should we ask for help from the regiment?"

Chu Xifeng thought for a moment and replied: "Don't be in a hurry to ask for help, don't we still have more than 100 people? When Liu Ergen heard Chu Xifeng say this, he sighed, didn't say anything, returned to the place where he was sitting, and picked up the rushing and sharp spears in his hands.

The Japanese attack continued, the second battalion was struggling to support, and in the last attack of the Japanese army in the evening, Chu Xifeng relied on the mortars, grenades and bullets in the battalion to come down, but more than 20 mortars in the battalion were also destroyed by the artillery fire of the Japanese counterattack, which also made Chu Xifeng's heart ache for a while. Seeing that the officers and soldiers of the second battalion who could still fight were less than a hundred people combined, Chu Xifeng finally grabbed the phone.

The regiment commander Wei Huang already knew that Jiangzhou Town would hold on for more than 15 days, and after receiving a call from Chu Xifeng, he heard that Chu Xifeng had reported the situation and asked for reinforcements, and Wei Huang immediately ordered the second battalion to abandon its position and withdraw to the town to rest. Then he called Wei Dalin, the commander of the first battalion on the second line. Wei Dalin is not only Wei Huang's cousin, but also Wei Huang's favorite general, Wei Dalin not only dares to fight in battle, but the important thing is that he is also very smart and smart.

Wei Dalin received the order and immediately asked the officers and men of his battalion to prepare, and tomorrow it was his battalion's turn to meet the enemy. The second line of positions and the first line of positions were separated by 500 meters, and they were also covered with bunkers and fortifications like the first line, and the trenches were dug carefully, and the difficulty of the Japanese army to capture the second line of positions would not be less than that of the first line.
