Accompanied by puffs of white smoke, he could even see sparks and bullets coming out of the white smoke. A swarm of bullets flew over, and they were enveloped in an instant.

At the moment when he was hit by the bullet, Lin Wei didn't feel any pain, not even anything, but felt a little heat when the bullet hit his body, and the blood flowed out and felt like sweating.

And then he fell, like all the wounded!

At the moment of falling, he saw that some of the brothers who jumped into the moat were knocked down by the rain of bullets that came from all around, and he could even vaguely see Jiannu operating the big and small Franc machines in the smoke of gunpowder to attack the brothers like a rain.

Damn it......

As his consciousness became a little blurry, he faintly heard a whistle, a whistle calling them to pull down.

The tentative assault is over.

……

"The attack has been thwarted?"

When he was still fifty miles away from Gaizhou City, Zhu Guoqiang smiled when he received the military information sent by Mei Chun.

"It seems that we did underestimate Jiannu!"

"Lord Shizi, judging from Mei Chun's report, it seems that Jiannu has a lot of firearms!"

Chen Wudi said.

"There are indeed a lot, our intelligence shows that there are now tens of thousands of craftsmen in the iron factory of Jiannu making firecrackers and casting artillery."

Zhu Guoqiang sighed helplessly.

Compared with weapons such as waist knives, tiger guns and armor, the fire gun is only used to fire the components of a few pieces of steel, the biggest is probably the width of half an inch thick nearly a minute of the plate, according to later generations, that is the "spring steel sheet", but unlike the spring steel used in later generations, this "U" thick steel sheet is just through the accumulation of size to use the elasticity of the ordinary steel sheet itself.

As for what no spring steel can not make a flintlock pistol, it is simply ignorant speculation, not only because the steel itself is elastic, "what does it mean to make a hundred steel, turn into a soft finger" is described in the poem The elasticity of a hundred steel, but also in China's unique lock spring and folding metal spring is also the evidence of the wide application of elastic deformation metal spring, this so-called "metal spring" technology has long been rotten in China, and it has actually reached the mouth of some kneeling people There is no spring steel in ancient China, and a flintlock pistol cannot be made. As for the ancient folding metal spring, its structure is similar to the U-shaped folding spring of the flintlock pistol, so they directly covered their eyes and said, "I can't see, I can't see, anyway, the ancients can't make it." Co-author: Only foreigners can make foreign things.

Although he never doubted the ability of the ancients, when the flintlock pistol made by Jiannu was sent to him by the internal guards, Zhu Guoqiang still looked a little surprised, and he didn't calculate that Jiannu would imitate the flintlock pistol so quickly. If I had known this, I would have used a firing pistol for the people in the morning.

After all, a flintlock pistol is a flintlock without a thunder cap, but unlike a flintlock pistol, it can be used as long as there is flint and gunpowder. The only thing that makes people happy is that the gun pipe made by Jiannu is far from being sophisticated, and the accuracy is not much better than that of the bird gun.

But, after all, this is a firearm.

Perhaps the most surprising thing is that Jiannu actually began to use firearms in large quantities.

Fortresses, firearms......

Isn't this a Manchu Tartar?

It seems to be.

The Manchu Tartars relied on the bird cannon to level the Jungar.

It's just that, historically, they learned to use bird guns, and now, they have learned flintlock pistols, and even learned bastions.

The fortress is hard to attack!

But...... No matter how difficult the fortress is, it will not be eliminated from the competition!

The corners of his lips lifted slightly, and Zhu Guoqiang said.

"Order the whole army to speed up its march and bypass Gaizhou City."

How was the bastion eliminated?

A hundred years later, in the Napoleonic era, the size of the army of more than 100,000 or even tens of thousands of people has become more and more common, compared to the attack and defense of the fortress, the operation of the army in that era is similar to the long drive of the blitzkrieg, however, they are not blind to the fortress, but at the same time divide the troops to cut off the supply of the fortress, of course, the widespread use of howitzers is also a threat to the fortress, in this case, the fixed fortress gradually withdrew from the stage of history, and the simple mud fortress that takes a few days to complete is more and more common, In the Battle of Lobodino, Jiannu's artillery relied on mud forts, causing heavy losses to the French army.

"Lord Shizi, what about Gaizhou City?"

Zhu Guoqiang said with a smile.

"I'll personally lead the troops over, I want to see how difficult the fortress-like fortress is!"

In the evening, when Zhu Guoqiang arrived at the front line in Gaizhou, Su Chun and other generals of Huwei Town pleaded guilty to him, and he just laughed at this.

"It's just a fight, what's not guilty. What about the casualties of the soldiers? How's the morale? ”

"Hui Shiziye, at the end of today, the general only made a tentative attack, and after being frustrated, he withdrew, and the casualties were only one hundred and eighty-six."

This kind of tentative attack, whether it is now or in the future, is very common, especially in the battle of the fortification, when the opponent is not clear, the tentative attack is a necessary choice to obtain battlefield intelligence.

"Well, the casualties are not large, how is the situation in Gaizhou City now?"

"Hui Shiziye, at the beginning, we underestimated the fortification, most of the defenders of Gaizhou City stayed under the earthen fortress built according to the roots of the city, the earthen fortress is composed of logs and thick soil, and they used mud baskets to build a parapet on the city wall, and the soldiers all had mud baskets as trench protection, unless the cannonballs fell directly into the basket trench, they would not cause direct casualties......"

The best learning is war!

Jiannu's learning speed is not slow!

Then again, if it were slow, I guess there would be no business for them. Smiling, Zhu Guoqiang stared at the sand table of Gaizhou City, and then fell into deep thought.

One of the simplest siege methods in the fortifications of this era was to concentrate siege fire completely in one place, open a passage, and then carry out a costly charge from there. Even this tactic will have to wait a few more decades before it is invented. When the famous Vauban was attacking the city, it first let the artillery fire grenades to kill and injure the defenders in large numbers. When the parallel trenches were completed, Vauban opened the gap with artillery and ordered the grenadiers to charge, capturing the fortress within ten days.

In order to improve the assault power of the infantry, Vauban invented the bayonet with both shooting and hand-to-hand combat, allowing elite troops to carry grenades, bombard the enemy with dense firepower, and then launch hand-to-hand combat with bayonets. The bayonet was invented for storming, not as a replacement for the spear.

However, both methods require a large number of casualties, ranging from a few thousand to tens of thousands, which is obviously not in line with the efficient combat pursued by Zhu Guoqiang. Moreover, he was deeply influenced by the thinking of modern warfare, and did not approve of a strong attack, unless it was necessary, not many troops were willing to choose a head-on hard encounter, and a detour was the most commonly used tactic, forcing the enemy to abandon the defensive line by detouring to the rear of the enemy's fortified area, and turning the attack into a field battle. But what if the enemy doesn't give up?

"To the east of the city, dig a parallel trench from the east of the city to approach the city wall, and then concentrate artillery fire on the east city!"

"Lord Shizi, our cannonballs are itching with the boots, what's the use at all? You can't blow up the people inside! ”

Zhu Guoqiang was not surprised by this, according to some information, when the fuse is set to be "instantaneous," the crater is very small, and a 122mm anti-explosive grenade, equipped with an instantaneous fuse, explodes on medium-hard ground, and the crater is about the size of a washbasin. If you want to destroy fortifications, or destroy anti-tank trenches, steep walls and other obstacles, the shell fuse should be set as a "delay", at this time the shell does not explode as soon as it touches the ground, but has a short delay after hitting the ground, so that the shell penetrates the target and explodes, at this time, a large amount of high-pressure gas generated by the explosion of the shell charge forms a shock wave, which lifts off the soil and scatters it, and can blow up a large crater.

"That's because our shells use instantaneous fuses!"

What is the purpose of the instantaneous? Of course, it is for the purpose of killing and wounding infantry in large numbers, but anti-fortifications are not his strong point!

Since it's not his forte, let's change another one that's his forte.

"This kind of shell doesn't work, then let's change it!"
