Before Christmas, Heynckes and his Sixth Regiment arrived in Dublin with the full force of ships and warships of the North Sea State. On the England side, because it needs to transport 15,000 combat troops and 20,000 civilians, it is still in the process of transportation.

Marin also came to Dublin with the fleet, but he did not plan to go to war, but only to make a show at the beginning. Moreover, Edward did not want him to go to war. After all, the reunification of Ireland is a very politically significant thing. Edward wants to be the emperor of the ages, so naturally he doesn't want others to steal the limelight.

So, Marin just came to Dublin to show his support for Edward. Then, it's time to go back. However, Marin sent an artillery battalion to facilitate Edward's siege.

This artillery battalion, sent by Marin, had 18 guns, 300 artillery. In fact, 180 artillery people operating the artillery were enough. The other 120 people were coolies in the reserve and carrying shells.

The artillery on land was different from the artillery on a battleship, which could have enough shells and gunpowder on board, and only a few people needed to serve each gun. And the artillery on land is more troublesome. Because, the army artillery needs to be disassembled and installed. When you get to the location, you have to dig a pit and get a gun emplacement that is easy to reset or something.

Moreover, through the war on the Italian side, Marin discovered that artillery could be protected by mounds......

Gonzalo. Morality. Córdoba was a skilled earthworking tactician, who liked to dig in front of his army to form a wall of earth to keep out enemy shells. The Spanish musketeers, on the other hand, hid behind mounds of dirt and could calmly abuse their opponents with muskets......

In fact, this trick is very useful even in the wars of later generations. In the anti-Japanese films that Marin watched, soldiers often appeared behind rudimentary fortifications made of sacks filled with dirt and shooting at the enemy. In particular, such scenarios are very common in street battles.

Of course, this defense has limitations. If the opponent only uses guns, it is indeed difficult to break through such a defense. But if the opponent uses artillery...... With the level of artillery during World War II, this rudimentary street fortification can be eliminated with absolutely one shot.

So, such fortifications, piled with sacks filled with silt, are only suitable for rookies pecking each other - everyone has no artillery, come on, hurt each other! But when you encounter a devil with a 92 infantry gun, you can't stop it......

At that time, during the civil war, everyone used Hanyang to build, and they could rely on the mound to shoot at each other with the enemy for a long time. But when encountering an opponent with aircraft artillery, directly GG ...... Of course, later our army realized the huge gap in firepower and simply switched to a night attack. At this time, the enemy was dumbfounded - Nima, my artillery can't show its strength in the middle of the night. Even if there is a flare, if the other party is familiar with the characteristics of the flare and hides it, the devil will be helpless......

Putting aside those superfluous thoughts, Marin found that in this era, because it was very difficult to transport artillery by land, it was generally possible to transport only some small-caliber artillery. This kind of artillery, the average shell is only 3 pounds at most, and it can't penetrate the mound at all......

Do you know why every time Turkey attacks the German region, it first attacks Vienna, the capital of Austria? It's not that the Turks are dead-eyed, but because - Vienna is on the Danube, which facilitates the transportation of artillery by ships on the Danube......

The Ottoman Empire had artillery, and the caliber was still very large. However, those large-caliber guns were very unsuitable for transport on the land march. Because Vienna was located on the Danube River, the Ottoman army could transport heavy artillery to the edge of Vienna by ship through the mouth of the Black Coast of the Danube, and then pull ashore to bombard the city of Vienna.

So, the army of Ottoman Turkey was very stubborn in besieging Vienna again and again, without choosing other directions for a breakthrough. Of course, there are also political reasons why Vienna is the nominal capital of the Holy Roman Empire. After all, having laid down the nominal capital of the Holy Roman Empire could break the confidence of the Germans......

……

However, Marin's artillery is different. He had long since come up with a two-wheeled gun carriage from memory, which could facilitate the transportation of artillery.

In particular, he also made a simple cage ball wheel bearing, which greatly reduced the resistance of the war horse to drag the artillery, so that the cannon with a weight of less than one ton could be pulled forward by the horse on the dirt road.

And this time he sent 18 guns, 10 of which were 12-pounder Napoleonic guns, cast in bronze. This kind of artillery is mainly used to destroy enemy battle formations. Twelve-pound iron ball shells flew by, striking a line that could smash through an entire company column at a distance of 600 yards, with great power.

As for the other 8 guns, it was even more powerful - it was the army version of the 8 32-pounder Karen naval guns......

Don't look at the large caliber of this artillery, but because of the short-barrel design, its barrel weight is only about 800 kilograms, which is not much heavier than the Napoleonic gun. If you only carry 8 doors, as long as the manpower is sufficient, the transportation can still be done. Of course, as long as it doesn't rain.

If it rains and the dirt roads are muddy, it will definitely not be possible to transport such heavy artillery. Unless, there are stone-paved Roman avenues. But Ireland has been an alien land for thousands of years, and the Roman Empire never conquered it. Therefore, there is no Roman road in the native-controlled area here. So, if you want to transport artillery, you can only wait for good weather......

Fortunately, the island of Ireland is so big, even if you wait a few days, the artillery will still be delivered. The Irish natives were generally poor, and the cities they built were small and dilapidated towns. Marin took out this 32-pounder Cullen cannon, which was definitely enough to blast open the city gates.

But considering that there are too many rainy days on the island of Ireland, even in winter. Therefore, Marin also specially equipped the artillery with a huge canopy to facilitate the firing of the cannon on rainy days.

As for the dampness of the gunpowder of the artillery, there is no such thing. Because, the artillery propellant of the North Sea Country is all sealed with waterproof oil-paper bags. Only before the cannon is fired, the seal is torn open and reloaded. Even on a rainy day, as long as the assembled canopy is built, it can be launched.

As for the canopy damaged by enemy artillery? does not exist, because, in this era, the indigenous Irish did not have artillery......

……

And in stealing the division of Gonzalo. Morality. After Córdoba's earthworking technology, Marin discovered that when digging trenches before the war, it was completely possible to put the excavated soil into sacks and pile it in front of the guns, leaving only the gaps in the barrel designed.

In this way, with the cover of fortifications made of sacks filled with dirt, the safety of the gunners was greatly improved.

You must know that artillery is a technical job in this era, and if you kill a single person, you will suffer huge losses. Therefore, after having the cover of fortifications made of sacks filled with earth, the artillery losses of the Beihai State in the future are estimated to be significantly reduced.

What the? Are you afraid that the opponent's artillery will do the same? Unafraid! Because, the pile of dirt piled up by the opponent could not stop the bombardment of the 32-pounder gun. Not to mention the bombardment of the iron balls of the 32-pounder Cullen gun, even the 12-pounder shells of the Napoleonic cannon were difficult to withstand by ordinary mounds of earth. Only the shells of those two- or three-pound cannons will be blocked by the mounds of dirt......
