After everyone finished laughing, Dai Ziran's baton slowly moved in the southwest direction:

"Look, this is Wujing Town, where the brigade headquarters of the 39th Brigade of the Guangdong Army is located, and its second regiment, its direct special service company, and machine gun company are stationed here, and a circular fortification has been established along the line from the north of the town to the east of the town...... The brigade has a total strength of about 4,200 troops, has a radio station, and its commander is named Ye Jinhua, 35 years old, a native of Meixian County, who is said to have graduated from the Guangdong Military Academy and once served as an ordnance instructor at the Huangpu Military Academy in Guangzhou. ”

"That's right"

Kang Ze interrupted Dai Ziran's words: "I remember this person very clearly, he once gave me a lesson, he spoke with a strong accent, and his personality was impatient and arrogant, so he has been depressed and unambitious for so many years, and most of the people with the same qualifications as him are already division commanders...... However, this person has real skills and is very good at military affairs. ”

Wu Ming nodded and motioned for Dai Ziran to continue.

Dai Ziran pointed to Nanxiong in northern Guangdong: "In the evening of the day before yesterday, our reconnaissance detachment was in Dongxiangpu, four kilometers south of Nanxiong County, disguised as villagers, and successfully captured two Cantonese soldiers who were going to prostitute in the village...... Garrisoned in Nanxiong was the 14th Division of the Guangdong Army, with division commander Chen Zhang, under the command of the 39th and 42nd Brigades, and one directly subordinate guard company, one machine gun company, one artillery company, and one engineer company, and the food supplies and ammunition were all supplied by the Third Army stationed in Shaoguan, and the total number of officers and men of the 14th Division was about 8,500 people. ”

"According to the continuous intelligence analysis, the Guangdong army is very well equipped, especially the 14th Division faced by our army, which has just completed the refitting two months ago, and all Czech rifles and Czech light machine guns, and most of the heavy machine guns are Lewis machine guns made in the UK...... However, this does not mean that the enemy we are facing is very strong, the discipline of the Cantonese army is sloppy, although the weapons on its body are good, but it lacks maintenance, and the units do not even have a minimum rear patrol and flank vigilance, and our reconnaissance team also found that there are heavy smokers in the Cantonese army, so it can be judged that the 14th Division opposite us is not the elite unit of the Cantonese army, let alone the 14th division of the Cantonese army that was brave and good at fighting during the Northern Expedition. ”

Dai Ziran paused for a moment, and the baton moved back and forth between Nanxiong and Xinfeng: "The weather has been good these days, and the planes of the Guangdong army frequently visit the skies over our army, and the number of voyages has increased significantly...... According to statistics over the past three days, Guangdong military planes flew a total of 57 sorties over Xinfeng, of which 14 hovered over Xinfeng City, and nearly half of the 14 were single-plane reconnaissance, and it is estimated that the situation in the airspace over Ganzhou and Dayu is the same. ”

"In view of the frequent reconnaissance by the Guangdong military planes, we have improved our strike plan, and plan to set up four dense machine-gun positions and camouflage them at Zhangjialing, which is 220 meters above sea level in the south of the city, Jiangjiashan at an altitude of 254 meters in the west of the city, Nanshan at an altitude of 182 meters in the southeast of the city, and Longxing Mountain at an altitude of 215 meters in the east of the city, waiting for the Guangdong reconnaissance planes to visit again and use the dense crossfire network to shoot them down."

Kang Ze was very excited, but he still carefully calculated the distance between the machine gun positions on several hills, and found that the distance between the four machine gun positions arranged in a triangle was within 1,400 meters, and the distance between the two peaks in the east and west, which were the farthest away from each other, was about 2,200 meters in a straight line. In addition, aerial reconnaissance generally needs to be reduced to an altitude of less than 1,000 meters, and Wu Ming's brigade's strike plan has a great deal of success.

Wu Ming saw Kang Ze's thoughts, smiled slightly, and pointed to Xinfeng City on the sand table to make a supplementary explanation:

"In the past few days, I have also carefully observed the flight and course of the Guangdong army's reconnaissance planes, and their reconnaissance planes have to fly low and hover over Xinfeng City several times a day, flying at an altitude of about 800 meters, and the speed has never exceeded 250 kilometers, or even slower."

"According to this situation, it can be inferred that the target of any two machine gun positions is within 1,000 meters, and our machine gun battalion is equipped with American Browning heavy machine guns, which have played well within this range, and the only difficulty is that they have never hit planes before, and the calculation of the advance amount is not very accurate, but it can be compensated by increasing the number of machine guns and the density of firepower, I have calculated that I am 70 percent sure."

Kang Ze nodded with satisfaction, which was roughly consistent with the results he had calculated, but he was still a little uneasy: "How is the performance of your Browning heavy machine gun?" How many are there? ”

"The specific model is the Browning Nl917 water-cooled heavy machine gun, that is, the prototype of the three-section heavy machine gun imitated and produced by the Hanyang Factory, with a caliber of millimeters, a gun body length of UU8 mm, a barrel length of UU7 mm, a maximum firing range of three thousand meters, an effective firing range of 1,500 meters, a gun body weighing 15 kilograms, and our improved gun carriage weighs 25 kilograms. Wu Ming was very familiar with the equipment of the department.

Kang Ze was finally relieved: "When are you going to act?" ”

Wu Ming replied: "We will start preparations tonight, we have completed the survey of each position, and two companies of the engineer battalion will assist in the operation. It's been a week of good weather, and I'm worried that if I wait any longer, the weather will get worse, and the planes won't be out of the air, whether it's strong winds or light rain...... In order to make the planes of the Cantonese army come faster, I planned to let the officers and men of the two companies quietly go around the north of the city after dark, and then raise as many torches as possible, form a long snake formation, and drive into Xinfeng City. ”

Kang Ze immediately understood: "You mean that there are Cantonese army spies in the city?" ”

Wu Ming nodded: "The advance personnel of our intelligence team came to Xinfeng City in various capacities five days earlier than us, and after investigation, it was found that a trading house engaged in the business of native products and grain, and a commercial bank engaged in mineral and machinery business, the big bosses behind them are all Cantonese, and the personnel of these two commercial houses have been coming and going very frequently in recent days, and we even suspect that there is a radio station in the commercial bank that is engaged in mining at the ferry port in the south of the city, but we did not alarm them, And the two bosses and several shareholders have good relations with local government officials. ”

Kang Ze was very calm, although he was deeply surprised by the intelligence methods of Wu Ming's department and Wu Ming's deep scheming, his face remained unchanged, and his attitude was still calm:

"Very good, I won't interfere in this matter, you can continue in your own way, I'll take a good look with you tonight, study hard, hahaha"

Wu Ming hurriedly said a few polite words, and instructed the adjutant to inform Long Shaogang, Zhang Dongning and the three directly subordinate battalion commanders to come to the meeting, and then accompany Kang Ze back to the main hall to drink tea and chat.
