It turned out that Lin Yuan's finger pointed to the Daling River on the east side of Jinxian County.

Wu Yuankai said: "How to ambush the Japanese army in the Daling River? The current Daling River has long been frozen into ice, and you can see the other side of the river from one end of the river, and there is not even a place to hide. ”

Lin Yuan smiled: "Don't worry, we are here to ambush the Japanese army!" ”

According to the people in the outpost camp, they were subjected to heavy artillery bombardment by the Qing army, and prior reconnaissance showed that the Qing army stationed in Jinzhou only had heavy fortress artillery, which could only be placed on the city wall, and it was impossible to take it down and transport it to the vicinity of the camp.

What's more: the artillery fire of the Qing army was extremely fierce and the rate of fire was very fast, even if the Qing army moved the fortress artillery, it would not be possible to have such a fast speed. Kawagu Masao couldn't help but think: "Is it that the Qing army has secretly increased its troops, and we don't know what to do, yes, it must be that the Qing army has hidden our eyes and sent troops to reinforce it." ”

At this time, the herald came to report: "The Qing army has been found outside the city defense of Jinxian County!" ”

Masao Kawagu hurriedly asked, "How many people are there?" ”

The herald reported: "According to the smoke from the Qing army camp, it is estimated that the Qing army has at least 6,000 people. ”

Kawagu Masashi thought to himself: "It seems that the Qing army really sent reinforcements. ”

Just as he was pondering, another herald came to report: The Qing army launched an attack on the northern part of Jinxian, and it has been repulsed so far, and Kawagu Masao immediately judged that such an attack was only tentative, and a real attack could come at any time.

Masao Kawagu quickly reported to his superior, Aota Tsuyoshi, the commander of the 18th Wing of the 1st Brigade of the 1st Division, who, as soon as he received the order, immediately ordered the three infantry brigades under his command to prepare and march towards Jinxian at any time.

Soon, this news was placed on the table of the commander of the 1st Division, Yamachi Motoji, who did not directly order Aoda Tsuyoshi to attack the Qing army on the outskirts of Jinxian, he thought that the Qing army might have set up an ambush on the road to support, but soon, the arrival of a telegram dispelled all his concerns.

This telegram was deliberately sent by Lin Yuan, the Qing army besieging Jinxian was insufficient, and the Qing army in Ningyuan hoped that the Qing army would support as soon as possible, and the commander of the First Division, Yamachi Motoji, immediately ordered: The 18th Wing of the 1st Infantry Brigade of the 1st Division stationed in Panjin immediately rushed to Jinxian to rescue the Japanese troops in Jinxian and wait for an opportunity to capture Jinzhou.

Lin Yuan found Chen Fei and said, "I want you to take a few people to carry out a mission." ”

Chen Fei asked, "What mission, is it to assassinate the mountain Genji?" ”

Lin Yuan said with a smile: "Mountain Yuanzhi is now far away in Shenyang, well, at this time, Shenyang is still called Fengtian, separated by hundreds of miles, you are afraid that you will not be able to pass, I want you to go to the Daling River to set up an ambush." ”

Chen Fei's eyes widened and asked, "Ambush?" You're not kidding, you asked me to take a few people to ambush three thousand! ”

Lin Yuan said: "Of course not! I want you to bring explosives and blow up the ice of the Daling River when the Japanese army arrives! ”

Chen Fei said in surprise: "Captain, this can't be your clever plan, right?" How is this possible? The ice is so big and so thick, how many explosives do you have to blow it up. ”

Lin Yuan said: "When you lay the explosives, make a hole in the ice, when the explosives explode, a stress wave will be generated to propagate in the ice, if we control the amount of explosives, then we can make the stress wave frequency reach the resonance frequency of the ice surface, so that the ice surface can be destroyed." ”

Chen Fei said: "This sounds like a hanging! Can it be done? ”

Lin Yuan said: "Don't forget, behind us are experts on the Beijing ship, and they will solve this small problem." ”

Lin Yuan quickly informed the Beijing ship of his idea, and the engineers on the Beijing ship quickly calculated the resonance frequency of the ice surface of the Daling River, and informed Lin Yuan of the amount and location of the buried explosives.

Chen Fei knew how to plant explosives, and asked: "There is another question, the Daling River is very long, how do we know where the Japanese army will cross the river from?" ”

Lin Yuan said: "We have found out that the Japanese army has left Panjin, and in order to rush to Jinxian as soon as possible, they will definitely choose the shortest path, so we can predict in advance where the Japanese army will cross the river." ”

Chen Fei nodded and went to choose a man.

As Lin Yuan expected, in order to catch up with the front of Ningyuan's reinforcements, the Japanese army deliberately accelerated the speed of the march, and the journey of one hundred and fifty miles took only one and a half days.

A team of 3,000 people, if lined up in a long line, it will be almost 3,000 meters long from the head of the team to the end of the team, this distance is enough for one person to run for more than ten minutes, once the leader or the end of the team meets the enemy, the reaction speed of the whole unit will be very slow, so the Japanese army adopted the method of marching in a horizontal line of four people.

According to the common sense of marching, the three brigades should be at least 200 meters apart, so that it is difficult to be surrounded, and when one brigade is attacked, the other two brigades can also take flexible forms of response such as flank outflanking.

Because of Lin Yuan's telegram, the Japanese army expected that the Qing army besieging Jinxian was insufficient, and in order to start the battle as soon as possible, the distance between the three brigades was only more than ten meters. When he was on the east bank of the Daling River, Qingtian Tsuyoshi gave a fatal order, the whole army rested for fifteen minutes, and the three brigades formed a horizontal formation and crossed the river together.

When later war historians analyzed this order, it was generally believed that Aoda Tsuyoshi wanted to put the three brigades into battle as soon as possible.

Fifteen minutes passed quickly, and three Japanese brigades marched onto the ice, which in northeastern China could be up to a meter thick at this season, so no one was worried that the ice would not be able to withstand the Japanese troops.

Suddenly, a dull explosion came from under the ice, which gave the soldier such a sensation due to the fact that the sound waves travel much faster in the solid than in the air.

Chen Fei and the others buried the explosives below the ice surface, and the stress wave generated by the explosion moved rapidly in the ice, if there was a person who could cut through the ice surface and observe the ice surface at this time from the side on a fine scale, he could see that the ice was fluctuating up and down like a sinusoidal curve, and every waveform that the ice oscillated would produce countless tiny cracks between the ice layers.

Just when the Japanese troops were puzzled, a series of explosions were heard one after another, and the vibration amplitude of the ice became larger and larger, and finally, a palpitating cracking sound was heard under the ice.

The sound of "click" was like the devil's big hand, which instantly grasped the hearts of every Japanese soldier, but they did not run in a panic, and Aota Tsuyoshi did not give the order to speed up the crossing of the river, because he knew the way, and it was very likely to speed up the destruction of the ice surface if he moved quickly.

At this moment, only a war horse neighed was heard, and in everyone's sight, the horse instantly became a lot shorter, and suddenly, a sense of foreboding enveloped everyone's hearts.
