Now the army troops of the Kingdom of Krul are crossing the strait, then directly entering the Valia Empire, and then rushing to the southern battlefield to fight against the Korkel Empire.
In the past few months, the Krul Kingdom has successively invested millions of troops in the western continent, and its war participation intensity is not much worse than that of the Daheng Empire.
More importantly, with the addition of the Krul Kingdom Navy, facing the joint maritime strength of the Krul Kingdom and the Varia Empire Navy, the Kele Empire Navy can basically only huddle in the port.
This means that the Kekel Empire has lost the ability to directly obtain external resources on its own coast and can only rely on the coastal ports of the Kingdom of Oran to obtain supplies.
The current war situation on the western continent is still quite anxious, which is in sharp contrast to the Daheng Empire's grand opening and smooth progress on the Orissa Empire's side.
Especially in ground combat, the war between the Daheng Empire and the Orissa Empire did not include the trench warfare between the Kekel Empire and the Valia Empire.
This is mainly due to the powerful mobility of the Daheng Empire Army, which means that the Orissa Empire simply does not have enough time to mobilize and deploy troops, let alone dig out an endless trench defense system.
The rapid mobility of armored cars and a large number of trucks is enough to serve as the motorized troops of the Daheng Empire. They can cover tens of kilometers in a single move and cover hundreds of kilometers in just a few days.
Such rapid mobility directly disrupted the Orissa Empire's defense-in-depth system.
Even the Orissa Empire couldn't figure out where the Daheng Empire's troops were...
They always feel that there are Hengmanzi on the front lines, in depth, and behind them...
In this way, the war situation in the northern peninsula quickly became clear.
Half a month after the war started, the 27th Army of the Daheng Empire marched tens of kilometers northward, reached the coast of the Endless Strait, and captured a small port and fort.
After the 27th Army captured the eastern end of the Endless Strait, it meant that the Daheng Empire had pried open the Endless Strait.
In the future, coastal defense guns and a large number of naval warships can be used to cover the transport ships through the endless straits, making cross-sea transportation more convenient.
As a result, the entire landing plan has entered the third stage.
One month after the war started, the Daheng Empire Army had already sent all its millions of troops to the southern shore of the Endless Strait, and directly captured the coastal areas on the southern shore of the Endless Strait, and then began to sweep southwards.
The Orissa Empire did not sit still and wait for death. After the early chaos, the Orissa Empire saw that the northern peninsula could not be defended and directly began to establish a second line of defense in the north.
That is to say, a dense defense line was built in a narrow area of about 300 kilometers wide directly along the southern part of the northern peninsula and the hinterland of the interior.
Three months later, after the landing troops of the Daheng Empire took over most of the northern peninsula, the Orissa Empire had already built a trench defense system here that was more than 300 kilometers long and more than ten kilometers deep.
At the same time, more than one million troops were deployed, plus more than 200,000 remnant troops who retreated from the northern peninsula. The initial total defensive strength exceeded 1.5 million people and thousands of heavy artillery.
They directly referenced the trench warfare of the Kokel Empire and the Valia Empire on the western coast, dug complex and dense trenches, and deployed a large number of heavy artillery.
Faced with this dense trench defense system, and the enemy had prepared three months in advance, even the Daheng Empire Army had to stop its pace.
Because in the face of this kind of defense system, it is impossible for the Daheng Empire Army to rush through. Those armored vehicles that are very useful in mobile operations cannot climb through such dense trenches, let alone face a large number of them.
It is basically impossible to resist the artillery.
After the Daheng Empire's troops heading south tried to attack, they gave up the idea of a forceful attack.
One tentative attack cost the troops heading south nearly 10,000 troops. This was not how this battle was fought.
b After Lin Ziran, who was far away in Jingzhou, learned about the situation on the front line, he also told the front line troops not to be impatient. By taking the northern peninsula, the Daheng Empire's strategic goal has been achieved more than half. As for the Daheng Empire,
In fact, the next step is to think about how to end the war.
Therefore, if it is not necessary, there is no need to sacrifice the lives of countless soldiers to storm other people's trench defense lines.
What's more, the battle cases on the western continent also show that this kind of trench defense system is temporarily unsolvable, and silly force attacks have basically no effect except for death.
But Lin Ziran knows that this trench defense system can be broken through, but it only requires a special weapon: a tank!
When he started developing gasoline engines many years ago, Lin Ziran had already begun instructing relevant research departments to study a series of tank front-end technologies.
Including high-horsepower gasoline engines, crawler transmission systems, etc. For this reason, the military has also equipped a series of crawler tractors to tow heavy artillery.
In fact, many front-end technologies have already been developed when the gasoline engine was first developed.
It's just that at that time, the technicians didn't know that Lin Ziran wanted them to build tanks.
It wasn't until the seventeenth year of Qian Sheng's reign that Lin Ziran officially ordered the formation of a special tank research project team and began secretly researching tanks.
But tanks are quite difficult.
For the Daheng Empire, this thing is more difficult than building a battleship.
Well, actually the same is true for other countries.
This is mainly due to the developed maritime trade in Blue Star Shanghai. Since ancient times, various countries have attached great importance to the navy. Therefore, the development of the navy has actually surpassed that of the army, and its technical reserves are also very strong.
As for the Army, it's a bit worse.
Many messy technical problems appeared one after another, making many technicians of the Daheng Empire's tank research project extremely crazy.
Of course, this is also because Lin Ziran has very high requirements for the tank under development.
Lin Ziran required the tank to be able to directly cross the trench, with a speed of no less than ten kilometers per hour, equipped with an artillery of at least 30 mm caliber plus at least one machine gun, and then a turret that could rotate 360 degrees in all directions, and
The tank is required to have the ability to defend against 11mm heavy machine guns.
These requirements can be said to be quite high in this era, posing quite high challenges to the industrial design and manufacturing capabilities of the Daheng Empire.
Since the 17th year of Qian Sheng's reign, engineers have proposed designs one after another and produced numerous prototypes, but in the end they were all rejected due to various problems.
In the ongoing research and development process, many plans have been proposed. In fact, now, the new plans proposed by designers are actually more similar to the tanks in Lin Ziran's memory.
There is no longer a messy multi-turret layout, but a very traditional classic tank layout such as a single gun, rotating turret, and multiple road wheels.
In February of the 21st year of Qian Sheng, that is, before the war with the Orissa Empire started, Lin Ziran had officially approved the final design plan of the tank and entered the small batch trial production and testing stage.
If everything goes well, it is estimated that this brand-new weapon will be put on the battlefield in half a year!
By then, the so-called northern second line of defense of the Orissa Empire will become a paper-like existence!
