In the Argentine presidential palace, the interim president of Argentina, Mitre, who is over 70 years old, is stamping back in the room, and from time to time he looks back at the map on the wall.

The map hanging on the wall covers the entire territory of Argentina, but the three areas marked in red, white and yellow on the map indicate that Argentina does not form a unified whole.

The six northern provinces marked in red belong to the areas occupied by the Han state, the areas marked in white in the central and western regions are the local opposition forces represented by Urquisa, and the yellow areas are the areas that obey the orders of the federal government.

Among the three areas, the white area is the smallest, and the yellow area is the largest, but a large part of the area covered by the yellow area is the Patagonia Plateau in the south, although the Patagonian Plateau is divided into the control of the federal government by Mitre, but due to the existence of local Indians and the penetration of Han forces, the Argentine federal government has limited control over there, and the climate of Patagonia is dry, and the barren land and sparse population cannot provide effective help to Mitre, so, Excluding the weakly controlled region of Patagonia, the area under the direct control of the Argentine federal government is not much larger than that of the local powers.

Argentina's worsening division stemmed from the defeat in the 1870 war, in which the Central Army suffered a crushing defeat in the battle between the Han National Defense Forces, and the former president of Argentina lost not only his life, but also Córdoba, where he had borrowed his position.

Located in central Argentina, the province of Córdoba is an important industrial base and economic center of Argentina, second only to the capital Buenos Aires in terms of economic and political status.

It was precisely because of the special status of the province of Córdoba that Mitre chose Sarmiento as his heir to power after resigning from the presidency, but what Mitre did not expect was that Sarmiento, who had always been favored by him, encountered a more powerful opponent, not only lost the army that supported his power position, but also lost the base area.

In Mitre's mind, the assassination of Sarmiento was an unfortunate event, and the consequences of the loss of the province of Córdoba were even more serious.

It didn't matter if Sarmiento died, Mitre had many cronies, and it was acceptable to choose a few more people as Sarmiento's replacements, but when Mitre's old rival took advantage of Sarmiento's assassination and the weakening of the authority of the central government to occupy the province of Córdoba, Mitre's situation became even worse.

Urquiza and his cronie Ferna occupy the two provinces of Argentina, and as Córdoba, the second largest province in Argentina, falls into his hands, Urquisa gains the capital to compete with Mitre in one fell swoop, and then, the situation in Argentina develops towards a situation that Mitre does not want to see, and the provinces around Córdoba Mendoza and San Juan have changed their courts to join Urquisa's side, and with the excuse of losing the war, he continues to pressure him, causing Mitre to plan to restore the Argentine economy. and population growth plans have not been effectively implemented.

Before the war of 1870, Argentina had a total land area of about 2.7 million square kilometers and a total population of 1.8 million, but after eight or nine years, due to the loss of territory in the six northern provinces and the continuous civil strife, even if the domestic white families maintained a high fertility level, the population of Argentina hovered only around 1.5 million to 1.6 million, far from the size of the population of more than 2 million in Mitre's target.

The seventies and eighties of the nineteenth century was the first outbreak of large-scale migration from Europe, but the turbulent situation in Argentina made it miss the most favorable opportunity to receive immigrants, and the vast majority of white people who intended to immigrate to Argentina gave up their plans to immigrate to Argentina because of fears for their own safety and other factors, and chose the United States, Canada, Australia and other regions as the destination of immigration.

In contrast to the slow growth of Argentina's population, the Han population continued to influx, which was only a quarter of Argentina's population a decade earlier, and by the end of 1878, the Chinese population of the Han Dynasty had reached 56.7 million, more than three times the total population of Argentina.

Population is an important manifestation of a country's potential military strength, and Mitre's rapid population growth has made Mitre feel a great threat, and the policy decree that Han has just issued directly makes him give up the last bit of luck in his heart, and makes him understand that the greatest challenge to determine the Argentine command has arrived.

The ambition of the Han State for Argentina can be described as Sima Zhao's heart, and everyone knows that Mitre has been preparing for the decisive battle with the Han State, but in Mitre's cognition, the big war between the two countries may not start until at least three or five or even ten years later, and he still has a lot of time to prepare slowly, but the sudden outbreak of the Guano War and the actions of the Han side seriously disrupted Mitre's deployment.

The number of federal troops had not yet recovered to the level they had been before 1870, and the federal government was not strong enough to suppress local opposition forces such as Urquiza, and war with Han was very disadvantageous to Argentina.

Of course, Mitre hoped to have more time to prepare for the decisive battle with the Han State, but the God that the white West believed in was obviously unable to fulfill his wishes, so when the war was about to break out, Mitre could only rely on the strength of the federal government itself to face the challenges posed by the Han State.

Mitre meditated in his room for a morning, and at noon, after roughly sorting out a plan to deal with the Han attack, Mitre instructed his entourage to invite Uruguayan President Lourenço la Torre to come and discuss important matters.

After the Han government issued a decree with war signals, it was not Argentina's interim President Mitre who was most anxious, but Uruguayan President Lourenzo Latorre.

Uruguay is a small country, and more than 60,000 square kilometers of the total land area of 170,000 square kilometers have fallen into the hands of the Han State.

Uruguay has a population of only a few hundred thousand, and the only way to protect its national security is to seek help from Argentina, so after Lorenzo Latorre learned the news of the Han state, he immediately took a boat to Buenos Aires, the capital of Argentina, to discuss with Mitre how to fight the Han state.

"President Lourenço la Torre, I think Your Excellency already knows very well what the decree issued by the Han Kingdom means, so I won't say more."

Mitre saw Lorenzo Latore who was hurrying over, and said directly, "Now what we have to do is to unite closely and jointly deal with the threat of force from the Han Kingdom, on this point, Your Excellency should have no doubts, right?" ”

"No, no, the people of Uruguay are willing to join the Argentine people in resisting the invasion of the yellow race in the East."

Uruguayan President Lourenço Latorre immediately stated his position.

"With the big war just around the corner, Argentina and Uruguay really need to work closely together."

Argentina and Uruguay were originally part of the congestion zone of La Plata under Spanish rule, and Argentina dominated diplomatic relations between the two countries, so Mitre was not surprised that the Uruguayan president was willing to be in a subordinate position to fight with Argentina against Han.

After agreeing on the ownership of the partnership between the two countries, Mitre went on to elaborate on a specific plan to deal with the Han threat:

Based on the geographical location of the Han Kingdom, I speculate that there are three main routes of the Han Kingdom.

The first is to start from Riolande do Sul and march from the territory of your country, first attacking Montevideo, the capital of your country, and then using Monteville as a base of advance to Buenos Aires.

The second is to go south along the Paraná River, capturing Santa Fe, Paraná, Rosario along the way, and finally besieging Buenos Aires.

The third is to use its naval power to land in La Plata, south of Buenos Aires, and threaten the security of Buenos Aires from behind. ”

"Which offensive route do you think the Han troops will choose?"

"The fastest route of attack is to go south along the Paraná River, but if the Han troops choose this route, they need to occupy the coastal fortresses such as Santa Fe and Rosario, which is very difficult.

Starting from Rio Grande do Sul and using your country as a springboard to finally attack Buenos Aires, the Han government needs to provide a large amount of logistical support for the attacking troops, and the material consumption is huge, which is not conducive to long-term warfare.

If the Han army chooses to land at sea, although it can avoid our defense forces deployed in the north, the landing force will also face the dilemma of material supply and limited number of transporters. ”

After analyzing each of the possible offensive plans of the Han army, Mitre explained: "Each of the three advance plans has its own advantages and disadvantages, and according to my judgment, the Han army may adopt a three-way offensive strategy, and then designate one or two troops as the main attack and the other as a feint attack in the three attacking forces." Of course, it is also possible that the Han State will attack the main force on all three fronts, but this is very unlikely, and I don't think the Han army commander will do this. ”

After judging the possible route of the Han army based on the information gathered, Mitre began to make-for-tat deployments:

First of all, the number of armed patrol boats in the Paraná River valley was increased, and the vigilance of the Han side was strengthened.

Second, troops were stationed in Montevideo, the capital of Uruguay, Santa Fe and Rosario, which are important cities along the Paraná River, and Laplace, a city in the south of Buenos Aires

Third, it promulgated a decree on tax reduction and the strengthening of local self-government, and called on young and strong citizens to join the army
