Chapter 419 (2/2)
And to the north of the fort is the broad Ohio River, and to the East is the Tennessee River, which joins the Cumberland River. These two rivers are like two natural moats, protecting the north and east of the fortress.
Not to mention the Ohio River in the north, where the width of the river has exceeded two kilometers. Although the Tennessee River in the East is not as wide as the Ohio River, its width is more than 500 meters.
In this era when the effective range of artillery is generally only a few hundred meters, it is almost impossible for an enemy to attack from these two directions.
In the West and south of the hill where the fortress is located, there are large marshes. There are only one or two paths explored by human life in the marshes, and only a few people can get in and out at the same time. This also eliminates the possibility of large-scale enemy attacks from these two directions.
It is worthy of being a military fortress carefully built by the French. This kind of terrain alone is enough to ensure the fortress is safe in this era.
The defense of the fortress itself is also excellent.
The fortress is built on the top of this small hill which is about 40 meters high. The area of the fortress is not large. It only has the appearance of about 10 mu of land. It is round and its diameter is about 100 meters.
The wall of the fortress is not high, only three meters high, but the wall is very thick. The most important thing is that there are four 24 pound fortress guns on the four special fort built on the fortress wall!
Although this kind of Fortress gun can't fire the blossom bullet, this kind of 24 pound fortress gun has a maximum range of nearly 3000 meters. Although the projectile fired is not much bigger than a big apple, and the effective range is only a few hundred meters, even the battleship sailing on the sea can make a hole if it is hit by this kind of bullet.
As for the small armed transport ships that can only sail in inland rivers, if they are hit by four such shells at the same time, they will be destroyed!
The four fortress guns are scattered on the north and East walls. Because there are marshes in the South and West, if the enemy wants to attack, they can only attack from the river. Therefore, the four most powerful fortress guns are specially designed to protect the river.
In addition, in addition to the four fortress guns, there are more than ten small caliber infantry guns on the fortress wall. At least after the stone bear entered okron fortress last time, he saw more than ten 4-pound guns and 6-pound guns.
Although the diameter of the bullets fired by the four largest wallier system fortress guns on the city wall is only one circle larger than a big apple, and the power of this kind of shells driven by black powder is far less than that of the smallest 20 mm machine gun of later generations, in this era, this kind of fortress guns, together with the ”artillery group” composed of small caliber guns, It's enough to frighten most of the enemy.
Generally speaking, the defense of this fortress is very good. Excellent terrain and thick city wall, there are so many guns on the wall, and there are all kinds of musketeers inside. In this era, this kind of defense can easily resist the attack of thousands of people.
But the stone bear is just going to move this fortress this time!
If it is someone else, after seeing the almost indestructible defense of Fortress okron, it is estimated that he will turn around and leave very quickly. Even the stone bear two years ago had this idea. But after the development of 55 mortars, the defense of okron fortress looks like paper in the eyes of the stone bea
