In Luc’s eyes, the Brittany’s investigation and probing were still very effective.

The Brittany, which was only four kilometers away from Cape Henri, could clearly see what the thing floating in the sky was. Although the captain of the Brittany didn’t know what it was, one of them was The big guy floating in the air seems to have little threat to the fleet.

　　 Because after seeing the big guy clearly, the thing seems to be motionless in the air, it should be fixed by a rope or something.

The most important thing is that the large-caliber mortar on the stern of the Brittany fired four rounds in a row. Although the shells fell into the sea far away from the coastline, the opposite shore defense artillery did not. Didn't you fire it?

　　 After the captain of the Brittany asked the signal soldier to tell the flagship what he saw through semaphores, Julian Luc immediately made a judgment.

　　 The thing floating in the air should be an existence similar to an observation post. Although Luc couldn't figure out how these native Indians made such a big guy fly, but since that big guy can't move in the air, it poses no threat to the fleet.

　　 As for that indigenous tribe’s shore defense artillery does not fire, that’s even clearer.

　　 This aboriginal tribe may really have a powerful artillery, but as I have judged, this artillery has a very short range, and it should be a fortress gun similar to a large-caliber mortar.

　　 Thinking of this, Luc couldn't help but complain to Henry Antoine secretly in his heart.

　　 You said that you are a senior navy general with rich experience in naval warfare, how can you lead your fleet into the inland waterway without a daze?

　　The battleship in your hand is a sailing battleship sailing on the sea, not an inland river armed transport ship sailing on an inland river.

　　If it were in the sea, the powerful artillery of that indigenous tribe would definitely not be able to hit its warship.

　　 Alas, what a pity those three battleships...

　　 Since there is nothing suspicious, just do it!

　　 Then, the flagship Glory issued a semaphore, and the eight sailing battleships of the Royal French Navy were photographed in a row, and they rushed toward the mouth of the Chesapeake Bay aggressively.

　　In Julian Luc’s plan, first destroy the fixed shore defense guns at a long distance, then rush into the bay, continue to destroy the remaining shore defense guns, and finally shoot at close range.

　　 It is close to noon. If everything goes well, destroy the shore defense artillery in one to two hours, then end the shelling of the indigenous tribe before night falls, and lead the fleet away from the Chesapeake Bay when night falls.

　　 This kind of sailing battleship that crosses the oceans is best to sail on the sea, that is the safest...

It’s just that Julian Luc never knows. At this time, the water dog, standing on top of a coastal artillery fortress, was holding a binoculars and looking at his eight warships, while listening to the signal soldiers next to him. The distance between the fleet and the shore defense gun.

　　 With guns aiming at the hot air balloon, Julian Luc’s fleet has nowhere to hide.

　　 The eight warships of the Guadeloupe Fleet of the Royal French Navy quickly moved into the farthest firing circle of eight kilometers from the shore defense artillery, but Water Gouzi did not order to fire.

　　 In fact, in terms of the range of the gun, it is already possible to shoot at a distance of eight kilometers.

　　Because of the limitation of the cannon steel material, the caliber of the artillery of the Yanhuang tribe has not been improved, and the gun is still the mainstay.

　　 The caliber of the artillery can't be increased, so the range is limited.

　　 However, the artillery engineers in the military factory have not been idle in the past few years. They have made a lot of improvements to the existing artillery under the guidance of Shixiong. For example, the installation of muzzle brakes, the development of anti-recoil devices, namely the parking machine and the recoil machine, and the installation of a high and low machine that can quickly adjust the muzzle, and a sight that can greatly improve the accuracy of artillery shooting. And sight.

The muzzle brake is necessary for army artillery, because this thing is to reduce the impulse of the gunpowder gas energy on the recoil part of the gun during the after-effect period, so as to reduce the recoil length and the force acting on the gun mount. .

However, although the muzzle brake can greatly weaken the recoil during shelling, when this is installed, the shock wave, airflow, fire and dust at the muzzle are increased when shooting, and it is safe for the concealment of the position and the safety of the gunner. Very unfavorable.

　　Moreover, with such a big iron guy added to the muzzle, the length of the barrel has been increased, which will affect the shooting accuracy and also affect the observation and aiming. The higher the efficiency of the brake, the greater the unfavorable factors. So anyone who can be uneasy is as uneasy as possible, like later tank guns, anti-tank guns, recoilless guns, and mortars, they are uneasy, and naval guns are not used.

However, it is very necessary to install a muzzle brake in the army artillery of the Grizzly Army, especially field artillery, because the installation of the brake can greatly reduce the recoil after all, and the maximum can even be reduced by 40%. As a result, the gun mount can be made lighter, and the maneuverability of the gun is improved.

　　 The army’s field artillery requires not only firepower, but also mobility.

　　 But like a coastal defense gun, there is no need to install a muzzle brake. With the current range of the gun, even if the enemy discovers the coastal defense fortress, their artillery can't reach that far.

　　 Compared with the mobility of field guns, shore defense guns need accuracy.

　　 However, even if the shore defense gun is not equipped with a muzzle brake, the retreating machine and the reclining machine are installed.

　　 In this era, when the field artillery fires, the recoil of the artillery is directly transmitted to the gun mount, and is transmitted to the ground through the artillery frame and the hoe. However, due to the moment of force, the artillery wheel will jump up when firing, and it will also move backwards. The gunner needs to push the artillery back to the original position and re-aiming before the second shot.

　　 Some large naval guns, fortress guns, and coastal guns~lightnovelpub.net~ are retreat guns that use sliding rails. This large-caliber artillery will be mounted on a slope-like slide. Each time it is fired, the gun mount will slide backwards on the inclined slide, and then slide forward to reset under the influence of gravity. The steel wheels and tracks under the gun base are used to adjust the gun's shooting direction. These cannon bodies are rigidly connected to the gun mount, and the artillery that uses the gun mount to recede to absorb recoil energy is called a retreat.

As for the artillery used by the Yanhuang tribe with the retreat and retreat, the barrel of the artillery is no longer directly rigidly connected to the gun mount like a retreat gun, but is supported on a U-shaped cradle, and then Together with this U-shaped cradle, it forms the pitching part of the artillery, and it pitches up and down on the gun mount. The barrel and the U-shaped cradle are not fixedly connected, but are connected by an elastic anti-recoil device. When shooting, the barrel can sit back on the cradle. The anti-recoil device absorbs energy, and then the barrel is fired. Return to the original location.

In the original historical time and space, the retreat machine and the reentry machine could not be developed until the last few years of the end of the nineteenth century. This thing works with the upper station **** to greatly stabilize the artillery and keep the artillery in the fire. Maximum stability, thereby maximizing shooting accuracy.

　　 Shixiong, with the help of the Golden Finger, directly raised the level of the 76 guns and 105 guns of the Yanhuang tribe for a full century!

　　 Therefore, even if the artillery level of the Yanhuang tribe is not as good as the artillery of the First World War, it is not far off.

　　 At a distance of eight kilometers, if a salvo of twenty-eight 105 heavy guns and 42 76 guns are fired, there is still a high probability that they can cover the target!
