This 125mm main gun is the second-generation naval gun developed by Fang Xiaoyue for the navy. The most amazing thing about it is its range!
The maximum range can reach an astonishing seven kilometers.
This is quite terrifying.
Such a range will make most warships in this era be beaten into a hornet's nest before they get close.
As for the main gun of the second-level battleship, it directly becomes the secondary gun on the first-level battleship.
This is not surprising, as the tonnage difference between first-class battleships and second-class battleships is somewhat large.
However, there are still some differences between the 88mm secondary guns of the first-level battleships and the 88mm main guns of the second-level battleships.
The 88mm secondary battery of first-tier battleships increases the rate of fire, shortens the range, and focuses on close guard defense capabilities.
Just before the summer of 1649, the Xinghai Kingdom formed a southward fleet to cooperate with the southward strategy of the Zheng family in Cochin.
After nearly a year of preparations for military reorganization, the Zheng regime's firearms force numbered as many as eight thousand, and it also owned one hundred Napoleon cannons.
There is no doubt that this is the limit of the Zheng regime's exhaustion of national power in a short period of time.
For this reason, the Zheng regime not only owed a loan of two million from the Xinghai State National Bank, but also signed a series of subsequent mine development agreements to make up for the debt.
To use an old saying, the Zheng regime at this time can be said to have failed or failed.
Because if they lose, not only will they not be able to repay the loan from the Xinghai Kingdom, but they will also be unable to resist the counterattack of the southern regime because of their injuries, which may lead to the destruction of the country.
Therefore, the Zheng regime not only dispatched 8,000 firearms troops, but also mobilized as many as 300,000 peasant soldiers!
Of course, these 300,000 peasant soldiers are not a complete combat force. The real combat force is only 100,000, and the remaining 200,000 peasant soldiers are logistics and transportation troops.
No way, considering the narrow mountainous terrain of Cochin, if you want to fly all the way from the north to the south, the logistics and transportation are quite difficult.
What to do if the problem is difficult? Then we can only increase the manpower of the logistics force to solve this problem.
In fact, Xinghai Kingdom gave them a better suggestion, which was to purchase Xinghai Kingdom's three-wheeled bicycles.
Although this kind of bicycle with three wheels cannot walk on flat ground in the mountains, it is at least much better than human hands carrying food and ammunition.
The only problem is that the Zheng regime is really out of money now, and the Xinghai State National Bank is unwilling to continue to increase the loan limit.
After all, the National Bank is a financial institution after all, and loan risks still need to be controlled.
Under such circumstances, the Zheng regime could only reluctantly give up the purchase of bicycles for the time being and spend its energy on the southern expedition.
As Prince Zheng, on behalf of the puppet little emperor, awarded Zheng Guoqi the general seal and appointed him as the general of the Southern Expedition, the Southern Expedition Army, numbering up to 300,000, then slowly moved towards the south.
Starting from Jiaozhihe to Zhengjiang, which divides the north and south, the straight-line distance is 310 kilometers. However, due to rugged mountain roads and other reasons, the actual distance exceeds 450 kilometers.
Even at the speed of Zheng's new army, the journey took a full half a month.
The two regimes deployed a large number of troops along the Zhengjiang River, among which the Ruan family had more troops. After all, throughout the Zheng-Nuan war, the Ruan family was on the defensive side, so they paid more attention to this natural danger.
The Ruan family stationed two camps in Xuanhua and Guangze respectively. The Xuanhua camp had 20,000 troops, and the Guangze camp had 15,000 troops.
Of course, this is not just the Ruan family's defense line in Zhengjiang.
You must know that these 35,000 troops are not peasant soldiers, but semi-professional garrison troops.
They are somewhat similar to the military households of the Ming Dynasty. When not fighting, they would farm near the garrison to solve their own food problems.
In addition, the Ruan family can recruit more than 100,000 peasant soldiers in nearby and subsequent territories at any time.
Even if the Zhengjiang defense line is penetrated, Tonghai, Guangling, Lishui, etc. all the way past will be heavily guarded.
With the ever-extending logistical supply lines, the rolling mountains and rivers, and the ever-increasing number of enemies, by the time the army of the Zheng regime reached Hue, it was almost exhausted and would be destroyed.
In addition, Hue's city wall was originally built to be taller and thicker over the past 300 years, which was almost unsolvable in the cold weapon era.
This is also the main reason why the Zheng regime made repeated southern expeditions and failed repeatedly.
Therefore, after receiving the news that Zheng's army was marching south, the current Lord Ruan couldn't help but smile contemptuously. He threw the general's newspaper on the long case piled with rare fruits, leaned back slightly, and turned his attention to the dancing girl.
On the dance posture.
But the news that came in the next few days was beyond Lord Ruan's expectation.
He never expected that Zheng's army would come so ferociously this time!
First, the Xinghai Kingdom fleet came up the river from afar and used artillery fire to baptize the city walls and barracks of Ruan's county along the way. After that, Zheng's army then crossed the river in countless wooden boats and attacked the two camps that were already in chaos.
.
Under the constant fire of the musketeers, Zheng's army easily defeated the two camps without even having time to use the Napoleon cannon.
Afterwards, the local government offices of the Ruan family who had no time to recruit peasants and soldiers were also strangled by the Zheng family's sudden army.
The fighting quickly spread to Hue, the capital of the southern regime.
More than 100,000 troops surrounded Hue Prefecture tightly, and the Xinghai Kingdom's fleet cruised along the coast, completely interrupting Hue Prefecture's information communication with the outside world.
Facing such a severe situation, Lord Ruan was pounding in his heart, but he remained calm on the surface.
After all, the city wall of Hue Province is probably the highest and thickest in the entire Cochin.
After surrounding Hue Prefecture, Zheng's army immediately brought in Napoleon cannons and bombarded Hue Prefecture day and night.
It's a pity that the Napoleon cannon is good for bombarding the city walls of those county towns, but it is a bit less powerful when used to bombard Hue Mansion on the city wall where horse racing is possible.
After three days of continuous bombardment and the consumption of thousands of artillery shells, large and small pits appeared on the city wall of Hue Province, but it is still strong.
The siege lasted for a long time.
Zheng's army besieged Hue Prefecture. On the surface, they had an advantage, but in fact they were at risk at any time due to the long logistics line.
Along this long logistics line, whenever the rebel army summoned by the Ruan family rose up, they attacked and killed the forage team and cut off the army's food and fodder.
In a few days, Zheng's army would be out of food and fodder and would have to withdraw and return.
In fact, this was one of the reasons why the previous southern expeditions failed.
Under such circumstances, Zheng Guoqi, the general of the Southern Expedition, had no choice but to beg the Xinghai Kingdom fleet shamelessly.
Xinghai Kingdom's fleet going south has nothing to do now, fishing and playing on the sea every day, which is extremely boring.
Therefore, Zheng Guoqi's request was agreed to, but the attack of the fleet going south was naturally not free.
