In this large area where the Tennessee River and the Ohio River meet, except for a few scattered hills, the rest of the area is very flat.

Of course, this flatness does not mean that you can trust the horse. After all, this is the confluence of two big rivers. Although it is flat, it is mostly swamp and woodland.

Just like the large swamps to the south and west of Fort Okron are the natural barriers of Fort Okron, even better than the Ohio River and the Tennessee River that act as a moat.

It is naturally impossible for the first regiment of the Burst Bear Brigade to attack from those two directions. Attacking from the swamp in this spring season is basically a death-seeking behavior. This huge swamp is enough to swallow tens of thousands of people in. There are more than a thousand people in the first regiment of the Burst Bear Brigade, which is not enough to see in front of this swamp.

The Ohio River to the north was too wide to be suitable for attack, so Shi Xiong set the direction of attack to the east of the fortress.

To the east of Okron Fortress is the Tennessee River with a river surface of more than 500 meters. Although the river surface is not wide, the current is very turbulent. Without a large enough boat, it is impossible to forcibly cross the river.

However, Stone Bear did not intend to forcibly cross the Tennessee River to attack Okron Fortress, and it would be no different from seeking death. Among other things, just the two fortress cannons facing this side on the Okron Fortress and the small-caliber infantry cannons are an insurmountable sky.

But there is no way for others, but Shi Xiong has full confidence.

Because the first regiment of the Burst Bear Brigade has as many as fifteen 55 mortars!

That's right, the entire Burst Bear Brigade was equipped with twenty 55 mortars. This time the division of forces, Shi Xiong brought fifteen mortars.

It’s not that the Stone Bear does not take care of the bighorn sheep. It is the West Route Army who fought along the way, and only the weak Chekashas have to face. The 55 mortar is not very useful when dealing with such weak chickens. A grenadier and a musket are enough. The five 55 mortars are only reserved for handling accidents.

The Northern Army wanted to attack the fortress of Okron, so it needed more 55 mortars.

Now the first regiment of the Burst Bear Brigade has more than 1,000 people, and these soldiers are all veterans. In addition to calling fifteen 55 mortars, the first regiment was also equipped with fifty grenadiers. In addition, there are two hundred cavalry equipped with blasting bear rifles, three hundred infantry equipped with blasting bear rifles, two hundred guerrillas and two hundred logistic and scout soldiers.

The first regiment’s armed forces are very powerful, and it is no match for the entire Burst Bear Brigade.

This time he was going to attack Okron Fortress, and Stone Bear was counting on the fifteen 55 mortars.

On the east bank of the Tennessee River, there are also several small hills that are 20 to 30 meters high. Now on the top of three of these hills, they have become 55 mortar positions.

The straight-line distance from Fort Okron to the west bank of the Tennessee River is no more than 400 meters, and the straight-line distance from these three hills to the east bank of the Tennessee River is no more than 300 meters, plus the width of the Tennessee River. The straight-line distance between the hills and Okron Fortress is about 1,200 meters! The distance of 1,200 meters is the best shooting distance for the 55 mortar!

At this distance, even the two 24-pound fortress guns on the walls of Okron Fortress facing the east could not play any role. Although this fortress gun has a range of 3,000 meters, its effective range is even less than 500 meters. At a distance of 1,300 meters, the gunners of the fortress cannons can only pray for God's love, otherwise, at such a distance, the cannonballs fired by the fortress cannons are enough to go tens or even hundreds of meters!

Yes, the artillery of this era is of this kind of virtue. Don't look at the range of the artillery as high as 3,000 meters, but the effective range is only a few hundred meters, and even a few hundred meters is a big deal! Otherwise, the sailing battleships of this era will not pull closer to 200 meters before firing...

Although this 24-pound fortress gun is placed on a turret, its stability is much better than that of a sail battleship gun, but its true effective range is not much stronger, and it is close enough to make you cry without tears.

For the artillery of this era, it’s not that your one shot misses and the next shot can be guaranteed to hit by adjusting the muzzle direction. The artillery of this era fired sub-caliber shells, and the diameter of the shells was smaller than the caliber of the barrel.

So when the cannonball is fired by black powder, because there is a large gap between the cannonball and the barrel, the cannonball will advance in the barrel in a "jumping" manner. A cannonball advancing in this way, the ghost knows which direction the cannonball is aimed at when it exits the chamber?

Even if the gun pops out of the bore by one millimeter, the error caused by one kilometer away does not know how many meters there are!

These three hills are 1,200 meters away from the Fortress of Okron. Therefore, the 15 55 mortars of the first regiment can appear on those three hills, even in France, which is fortified by Okron. It doesn't matter if people see it. Shi Xiong and the others just stood here and let the artillery hit them, and they couldn't hit them either.

The most important thing is that with the rate of fire of the mortar, it is estimated that the fortress guns in the fortress of Okron need at least one minute to load a shell, and at most, there is only a chance to fire one shell...

There are three small hills, and five 55 mortars are arranged on each hill, ten of which are dedicated to bombing the fortress of Okron, and the remaining five are dedicated to "care" from the fortress To the 400-meter-long stepped road between the piers.

Shi Xiong never thought of giving the French in the fort a way to survive. The main entrance and exit of the fortress is the wooden pier on the west bank of the Tennessee River. As long as the road leading to the pier is controlled, the French escape route can be cut off.

Although there are trails in the swamps to the west and south, the Stone Bear had made 500 cavalry and infantry equipped with Burst Bear rifles to cross the river several kilometers away from the fortress long before the mortar position was built. On the Tennessee River, a long ambush circle was constructed on the periphery of the swamp.

As long as someone dares to walk the path in the swamp, they will be taken care of by these musketeers in every possible way~lightnovelpub.net~ Ishikuma doesn’t believe it at all. In front of 500 blasting bear rifles with an effective range of 600 meters, they still Anyone can escape this swamp. Even shooting at a distance of four hundred meters is enough to strangle the French from escaping the swamp path!

Originally, Stone Bear was a little worried about the crocodiles living in the swamp, but this time is far from when the crocodiles wake up from hibernation. As long as they don't deliberately provoke these terrifying big guys, these crocodiles won't jump out to find trouble.

When the soldiers of the first regiment were building their positions and ambush circles, the French soldiers in the Okron Fortress had already discovered them, but they had no choice but to watch the "small black spots" in the distance. Ants are also active.

When the mortar position was constructed under the rays of the rising sun, the stone bear issued the order to attack.

"There are all 55 mortars, let's test fire one shot, and measure the distance and direction!"

Following this order, fifteen 55 mortars fired at the same time, and fifteen sharp whistles resounded through the world...
