Gudra used to be only a local force, and there was no regular army in his hands, although his soldiers equipped with Arthur 88 rifles were enough to have six corps and 180,000 troops, but because of lack of training, the combat effectiveness was incomparable with the regular army.

Therefore, under the sudden attack of the royal army, Gudra's army had to withdraw to their own territory, relying on hastily built fortifications. Admiral Calgis knew what it was like, and when he saw Gudra go on the defensive, he knew he couldn't wait any longer. Once Gudra is eliminated, the next person to die will be himself, and even if he does not rebel, the royal family will find an excuse to get rid of him, or force himself to rebel.

Immediately after the large-scale offensive of the Moss government army, Calgés issued a public statement, declaring that the Moss royal family had been a vegetarian for a long time, only knowing that the Moss had oppressed the common people and extorted tyranny, and his rule was rotten to the core, and he demanded that the king abdicate and form a constitutional monarchy in the kingdom of Moss like the Empire of St. Martin.

Seeing Kargess's statement, Hernande trembled with anger, and he didn't expect that the plan to make them fight in two places was unsuccessful, and he was actually tricked by him, losing a large number of weapons and equipment. Hernande, who was furious, immediately issued an order, calling Kardjes a traitor and demanding that the border guard generals not follow him in rebellion, and that anyone who followed Kargis in rebellion would be punished as treason.

Calgis is waiting for this news, with this news, even if there are people in the border guards who still want to be loyal to the royal family, there is no way, after all, it is still their own life that is the most important, as long as they use the names of all the generals to publish the telegram, who will not desperately resist for their heads.

Two days later, Calgés declared the independence of the provinces of Gutiérrez and Mansanier, and at the same time formed a military junta, with Kargés as the supreme leader, and announced that the border guards would help Gudra's autonomous army and join them in opposing the tyranny of the government of the kingdom of Moss.

Gudra, who had been overwhelmed by the government army, was very excited after receiving Kargess's briefing, and he immediately wrote back to Kargis to express his goodwill, and at the same time hoped that the two armies could be unified in command to jointly fight against the royal army.

Unified command was impossible, and Largeus ignored him at all, as the border guards had a higher combat effectiveness than the government army, and although they had the least number of their own troops, they did not need to be feared at all. Taking advantage of the fact that the government troops did not have time to adjust their deployment, the well-trained border guards quickly launched an attack from the flank of the government army, forcing the government army to abandon the attack on the autonomous army, and retreated 30 kilometers before stabilizing its position.

The civil war in the Kingdom of Moss has begun, except for the Yaman Empire and the Chinese Empire, which are secretly funded, no country can intervene in it, and when the three strongest countries in the world are playing, other countries can only watch the show. Due to the sensitive oil issue, whichever side actually intervenes first may withstand the joint resistance of the other parties, so in the territory of the Moss Kingdom, the three countries can only support their own forces behind the scenes, and the first proxy war under the new world pattern begins.

NATO, the Allies and the Boston Empire are all relatively restrained, in order not to expand the scale of the war, they have not provided advanced weapons to all parties in the Moss Kingdom, there are only a few torpedo boats on the warship, and the air force is completely absent, and the army weapons are only manual rifles that have begun to be eliminated, and a few old water-cooled heavy machine guns, not even mortars, let alone combat vehicles.

The war in the kingdom of Moss seems to repeat itself, with both sides fighting each other with weapons that they have equipped years ago, and each side is trying to make money in order to expand its military power against the enemy army. The best way to make money in the Moss Kingdom is naturally oil, and the self-government of Gudra and the military government of Kargis immediately purchased oil extraction equipment from their respective masters.

If no one would sell them these advanced drilling equipment in normal times, but now is a sensitive period, and companies from any country do not dare to rush into this hot spot, so it is cheaper for these two parties to let them mine on their own, while those foreign companies are only responsible for purchasing and transporting.

After having sufficient equipment, both sides soon began to dig wells in their own territories, and vigorously exploited oil, exchanging cheap oil for the arms of their masters, and the powerful armies of both sides soon began to expand rapidly.

Seeing the actions of the two sides, King Fernand of Moss could only reluctantly follow up, importing equipment from the Boston Empire to develop oil fields, and the government began to extract oil in its own control area, and the extracted oil would also be sent to the Boston Empire in exchange for sufficient military assistance, and then the contradiction arose.

Expanding the army requires a lot of oil, and the territory of the autonomous government and the military government together only accounts for 30% of the land area of the Moss Kingdom, and their oil reserves are naturally not comparable to the royal family, so their desire for new territory drives them to attack the royal family.

The Frontier Army, which had expanded to more than seven corps, began the offensive first, with Calgis attracting the main royal force on the frontal battlefield with four corps, while his most elite First Army launched a landing operation in the port of de Ostura, escorted by a large number of collected merchant ships and fishing boats, escorted by only five torpedo boats.

The port of Deostura is a small fishing port, the strategic location is not important, and the water depth is too shallow to dock large warships, not even fully loaded merchant ships, so it has always been relatively desolate, and the harbor is only a few dozen fishermen living here, relying on their ancestral ability to go to the sea to make a living, but it will soon be lively because of a war.

Caljes's landing force did not have any large warships, even merchant ships were few, and most of the soldiers were on fishing boats, but fortunately, the port of Deostura was not far from his base, and the road was all near the sea, so there would be no danger.

It was very fitting for the fishing boats with a shallow draft to land in the port of Deostura, where there were no troops stationed and the fishermen would not resist, and the vanguard of the border guards who landed first sealed off the entire port to prevent the news from leaking. Subsequently, a large number of border guards and their supplies relied on fishing boats and boarded the port docks without the knowledge of the royal army.

A few merchant ships kept shuttling between the base and the port of de Ostura, and then the fishing boats transported the supplies to the shore little by little, but the efficiency of the fishing boats was too low, and the speed of supply delivery was very slow.

Even so, after a week, the troops were still not fully supplied, and many pieces of equipment stayed at the base and were not delivered. Major General Bled, the commander of the First Army of the Frontier Army, knew that he could not wait any longer, and the 30,000 horses stationed here were too big a target, and he could be discovered at any time, so he decided to take the initiative to attack with insufficient supplies, disrupt the rear of the royal army, and create an opportunity for his own frontline troops to attack.

The attack is naturally methodical, and the best way to attack is to attack those weakly defended key areas, and the key point of the royal army is the material supply base in the rear, Kolima is such a place.

With a population of 300,000, the city of Colima can only be regarded as a third-tier small city in the Chinese Empire, and such a scale is already a rare large city in the Kingdom of Moss, because it is only more than 130 kilometers away from the front line of the Balthus River, it has become an important material distribution center for the front-line government army.

In the eyes of the top level of the government army, Kolima belongs to the rear, and it will not be attacked by the enemy at all, so the government army is very assured of the safety here, in this city the government army only has one division, less than 10,000 troops for defense, in addition to nearly 20,000 logistics soldiers responsible for the delivery and storage of materials all year round, of course, these logistics soldiers do not have much combat effectiveness, they are not even equipped with weapons.

The defense of the rear by government forces was very lax, and with the exception of a few fixed transport routes, scouts were not sent at all in other areas. In their consciousness, war is a front-line affair that has nothing to do with them, and landing operations or aircraft bombing are not within the scope of their consciousness at all.

This is indeed the case in the kingdom of Moss, where wars rarely occur, and his way of fighting is still very ancient, only knowing that the road is advancing in parallel and fighting hard, which makes the defense of Colima City, which is in the rear, very lax. However, the border guards did not have planes to bomb them, and they were not in any danger in normal times. Even Caljes was reminded by military observers sent by the Chinese Empire to learn about the mode of warfare of landing operations.

Major General Bred also had little experience with this kind of sneak attack tactic, and instead of sending a crack squad to carry out a sneak attack, he marched his whole army towards the city of Colima, hoping to capture it before the other side reacted. But how can the 30,000-strong army move secretly, twenty kilometers away from the city of Colyma, Major General Brad's troops were discovered, and the terrible sirens instantly sounded throughout the city, and the defending troops of the government army immediately entered their positions, and seeing that the sneak attack failed, Major General Braid had to order the troops to form a battle formation and prepare for a strong attack.
