After all these preparations were completed, Li Yunlong pulled up the "Ghost Cannon".
Li Yunlong pointed to the turrets in front and said to Laojiu: "First hit the one directly in front, and then the ones on both sides. There are three turrets in total. Is there any problem?"
Li Yunlong had planned this early in the morning.
There are five blockhouses in front of Nantu Village, which stretch for two kilometers along the road.
Only by knocking out the three turrets in the middle can the independent regiment open a fire gap and break through this line of defense.
Laojiu hesitated for a moment and then responded: "No problem!"
In fact, even though there is the distance measurement method of Xiaodongbei, if ten artillery shells hit three turrets, Laojiu still has no clue.
But Laojiu also knew that Li Yunlong was asking a question, and what he wanted was the answer of "no problem".
Li Yunlong patted Laojiu on the shoulder and asked him to get ready.
The old wine is ready.
But we didn’t prepare it just now. When Li Yunlong held the meeting, Laojiu was thinking: If we wait until dark to measure the distance and altitude, that would not be a problem, especially because the soldiers can’t do mental arithmetic yet, so they have to do it on paper.
It is written that it will be all black and it will not be good if the calculation is wrong.
So as soon as the meeting ended, Lao Jiu asked Li Yunlong for instructions and hurried up with a few soldiers carrying the benchmark.
We didn't encounter any difficulties after arriving at the place. It was just to prevent the Japanese from finding out that it was a bit troublesome to measure secretly, but it was difficult for the Japanese to find them one kilometer away. Soon Laojiu had measured the distances and heights of several targets and recorded them.
Marked.
But Laojiu soon discovered something was wrong.
"We can't test like this!" Laojiu said: "This battle will be fought at night. We can obviously fight at 500 meters or even closer, so why do we have to fight at 1,000 meters away?"
There is nothing wrong with this, because due to the influence of wind strength, wind direction and other uncertain factors, the hit rate of 500 meters is definitely higher than that of 1,000 meters.
At the same time, the enemy's firepower was unable to threaten the enemy five hundred meters away due to low visibility.
So of course the artillery had to be pushed to 500 meters to fire.
The problem is...
Five hundred meters is too close. It's still daylight now, and the Japanese are out supervising the people's work. If we go to 500 meters, we will definitely be discovered by the Japanese.
A soldier made a suggestion: "Uncle Jiu, let's measure the point at a distance of one thousand meters first, and then walk 500 meters from this point towards the gun tower in the evening. Isn't there only 500 meters left?"
Laojiu raised his hand and gave the soldier a blow on the head: "You want it to be so simple? What if I'm stupid? This method is only suitable for flat ground all the way. It's undulating here, and there are still hills in some places. You
If you push forward 500 meters, can you get exactly 500 meters left?"
The soldier was speechless after being told this by Laojiu.
Laojiu is right, if you want to do this, the height and distance will be wrong, and it will be strange if you can hit it.
In the end, Laojiu came up with a way. He measured the distance from an obvious target, such as a stone, between the benchmark and the gun tower in the same way, and then subtracted the two distances to get the distance from the stone to the gun tower.
Measure the height again by subtracting the two heights to get the relative height.
Worried about making mistakes, Laojiu measured a few more positions and wrote down the data one by one.
After returning to the army, Laojiu immediately went to find Wang Xuexin, put the data in front of Wang Xuexin, and asked if this was feasible.
Wang Xuexin was stunned when he heard this. He could learn and use this skill from an old man. The potential unleashed under the pressure of war was so damn different!
At this moment, Laojiu just pushed the cannon to the mark, used the calculated data to adjust the points and aimed it at the front turret.
There was silence all around. Even the insects were silent due to the cold weather. Only the mountain wind blew through the empty village, making a "whining" sound like crying. Occasionally, you could hear the sound of empty cans on the barbed wire fence swaying in the wind.
"Bang" sound.
Wang Xuexin, who was lying in front of the position, closed his eyes and tried to feel the tranquility and peace of this moment. Although it was only superficial, it still made him nostalgic.
Suddenly, several red flares slowly rose into the sky.
The battlefield became lively at that moment, with gunshots everywhere, and about 50,000 people from 22 main regiments ambushing on the front line simultaneously launched an attack on the unsuspecting Japanese defense line.
The Japanese never dreamed that the Eighth Route Army, which had always been on the defensive, or had launched sneak attacks with a small number of guerrillas, would actually launch a counterattack of this magnitude.
However, the Japanese did not dare to leave the blockhouse, so they could only use searchlights to search for enemies in suspicious directions, and then shoot randomly from inside the blockhouse.
The soldiers of the first battalion rushed up through the gap in the barbed wire fence immediately.
The Japanese discovered them, and their searchlights immediately focused on the gaps in the barbed wire fence. Machine gun bullets flew towards them with whistling sounds, knocking down the few soldiers who were ahead in a pool of blood on the spot.
Wang Xuexin raised his gun and turned off the searchlight with a bang, and the surrounding area suddenly fell into darkness.
At this time, Wang Xuexin heard Li Yunlong shouting: "Old Jiu, fuck me!"
With a "boom" sound, the shells flew out from the muzzle of the "ghost cannon".
But there was no explosion or fire. The perforations in the turret were still spitting out tongues of fire crazily, suppressing the charge of the first battalion of soldiers. At the same time, the puppet troops in the second-line civilian houses also rushed up with guns under the intimidation of the Japanese to organize defense.
"What a trick!" Li Yunlong yelled: "What a ghost cannon, it didn't even make a fart noise when fired!"
This is a flaw of the round-nosed bullet. As mentioned before, when launched at a small angle, it is likely to float on the ground without exploding.
The result of not exploding in the dark is that you don't know where the shell landed, so you can't make corrections based on the explosion point.
At that moment, Laojiu was stunned for a moment, his mind went blank. He didn't know whether to adjust the Zhuyuan shot or continue to play like this.
If it needs to be adjusted, how should it be adjusted?
Until he heard Wang Xuexin shouting in the darkness: "Wind offset!"
Laojiu understood instantly.
It's not that he hasn't considered the amount of windage. As a gunner who has been working for several years, Laojiu will certainly not miss this. He has even brought the amount of windage into his own feelings, knowing how far away it is and how big it is.
Wind, how much will the wind deflect in any direction?
The problem is that this feeling is caused by shooting pointed cannonballs.
The self-produced "ghost cannon" uses round-nose bullets, which are definitely more affected by wind than small-cone pointed bullets, so if you shoot with the same feeling as before, there will be problems.
How big is the specific impact?
How much bias should it be?
There is no standard and no reference.
Laojiu could only make adjustments based on his feeling, and then gave an order and fired another cannonball with a "boom" sound.
Laojiu didn't hold out much hope, so when he saw a fireball explode in the middle of the turret, he couldn't help but be surprised, so much so that he didn't believe that he fired the shot.
Until Li Yunlong yelled at him: "Old Jiu, you damn good shot, one more shot!"
