Chapter 1548 A Game of Chess in the Far East ([-])
Gao Wushi’s remarks are relatively informative, and mainly mentioned two things. One is that if there is a big gap in Jinghua’s funds, he is going to develop the Sado Gold Mine; Crisis to rent half of the Miura Peninsula.

The Sado Gold Mine is the first large alternative gold mine discovered in Japan after Kaijin was "exhausted" during the Takeda Katsuyori period.It was one of the three major gold mines in Japan during the Tokugawa shogunate, and its output accounted for half of Japan's. It has been dug for 400 years, and it was not until 1989 that it was exhausted before it entered the 21st century.

However, this is not the primary reason for the high-practical idea of ​​Sado Gold Mine, because if we want to compare reserves, grades, mining difficulty and other aspects, then Sado Gold Mine is actually not as good as Hishikari Gold Mine.

The Hishikari Gold Mine is located about 45 kilometers north-northeast of Kagoshima City in the southern part of Kyushu, Japan. It is in the northeast of the Kita Satsuma area. It currently belongs to the border area between Satsuma and Osumi. Part of it belongs to Satsuma and the other part belongs to Osumi.

Of course, both Satsuma and Osumi are the territory of the Shimadzu family. Speaking of which, it should be very convenient for Jinghua or the Maritime Trade Alliance to "discover" this high-grade large gold mine that was originally discovered around 1750.However, there are two major problems with the gold mine that lead Gao Pragmatic to hide it first.

One is political and military considerations.At first glance, the Shimadzu family is following closely with the Maritime Trade Alliance, even going so far as to clearly declare that they are descendants of the Qin Dynasty.However, judging from the performance of the Shimadzu family after Toyotomi Hideyoshi asked the Shimadzu family to follow him to send troops to Kanto, they are still speculating on both sides according to the "tradition" of Warring States Japan.

Although it is not incomprehensible to be highly pragmatic in this approach, understanding is understanding, and defense is defense. Since the Shimadzu family does not dare to devote themselves to the Maritime Trade Alliance camp and draw a line with Toyotomi Hideyoshi, then naturally high pragmatism will not be careless Trust them unconditionally.

What's more, Gao Pragmatic's method of controlling the Shimadzu family is to first consider economic penetration, and then consider military penetration. It is still in the stage of economic penetration, and the military does not have much pressure on the Shimadzu family. Sea power is of course suppressed, but The Shimadzu family at this moment is not the Satsuma clan after the Meiji Restoration. The navy is not their forte, but the army is their strength.

Under such circumstances, since Gao Wushi did not send an army to the Shimadzu family, how dare he go and discover such a large gold mine?In case the Shimadzu family sees the money and decides to dig it themselves instead of "cooperating", it is not good to be highly pragmatic and send troops to fight the Shimadzu family now, right?In that case, the previous Japanese plan would basically have to be overthrown and restarted.

But politics and military affairs are only part of the reason, and the bigger reason is the problem of the gold mine itself.Although the Lingjia Gold Mine is a large gold mine, it has been continuously mined during the time of high-level travel, not only has huge reserves, but also has extremely high grades. However, this "huge reserves and high grades" are all aimed at high-tech mining levels Word.

In fact, although the Japanese discovered gold mines in the Lingjia area in 1750, they only carried out exploration and small-scale mining intermittently thereafter. In 230, due to the unsatisfactory condition of the vein, the exploration was stopped.

Before the mid-20s, no basic regional survey was conducted in this area. Later, after many geologists from Sumitomo Company analyzed the regional metallogenic geological background, it was determined that the Northern Saxony area was rich in gold deposits. There may be hidden gold deposits under the Pleistocene volcanic rocks in this area, so it is recommended to use advanced methods for exploration.

In this context, from 1975 to 1977, the Japanese Metal Mining Corporation carried out regional geological surveys in the Ikushino area of ​​Beisa, and the selected working area was 900 square kilometers. In 1975, a gravity survey was carried out in the whole area, and a regional geological survey was carried out in 1976-1977, and the main geological structures were finally identified.

In 1978, on the basis of regional geological survey and gravity survey, regional electrical sounding and airborne electromagnetic survey of Slomberg arrangement were carried out in the Dakou-Lingjia area (high gravity area), and it was found that the upper and lower parts were high resistivity layers, A high-low-high three-layer structure with a low resistance layer in the middle.

After more than ten years of detailed investigations, at the end of 1985, Sumitomo Mining Company summarized the existing data and finally came to the following understanding:
First, the volcanic rocks in this area were originally considered to belong to the Miocene, but they were found to be Pleistocene by K-Ar dating;

Second, the K-Ar analysis of ice-feldspar-bearing ores confirmed that the age of gold mineralization was 80-100 Ma);

Third, the high gravity and deep resistivity are equivalent to the local uplift of the basement (Shimanto supergroup), while the low resistivity near the surface is caused by hydrothermal altered rocks (containing smectite and interlayer clay minerals near the mineralization zone) of;
Fourth, the abnormal induced polarization in the low-resistivity zone is very consistent with the distribution of the main vein system.The most exciting discovery during these studies was that a geophysical assemblage similar to the present deposit (induced polarization anomaly in a low-resistivity zone) extends under young volcanic rocks in the Yamada area, 1.2 km southwest of the main deposit of the present mine.

These statements may be too professional, but in short, they concluded that the Lingjiae deposit is located at a depth of 150 meters below the surface. Quartz, calcite, ice feldspar, chlorite, zeolite and clay minerals, etc.

To put it more simply, the mine is good, but not easy to mine.At least for the current era and the level of technology possessed by Jinghua, at most it can only develop the upper part of the mine, and the upper part of the mine is neither rich in reserves nor high in grade. suitable.

In fact, if you think about it, why didn't a big gold mountain like Lingjia Mine be discovered until the 80s?The reason is that both the Sado Gold Mine and the Konomai Gold Mine (in Hokkaido) were formed 1000 million years ago, but the Hishikari gold deposit is estimated to have been formed 100 million years ago.

From a geological point of view, the Lingjia Gold Mine is a very new mine, so its ore veins are not exposed on the ground, so it is difficult to be discovered, and even if found, it is difficult to mine.

Now that the Hongzhimai Gold Mine is mentioned, by the way, there are two main reasons why Gao Yushi did not dig it: one is that the weather in Hokkaido is not conducive to mining under the current technical conditions, and the other is that there are no people in Hokkaido now. It is practically impossible to mobilize at least 1 people to mine there - the cost is too high.

From this point of view, the Sado Gold Mine is actually the most suitable for highly pragmatic ideas at present.Sado Island hangs alone in the northern sea off the Echigo region of Japan. The current ruling daimyo is the Uesugi family. There used to be a local daimyo, the Honma family (Sado guardian generation), but it happened to be attacked by the Uesugi family this year (1589). .

The Uesugi family fought relatively smoothly in this battle, and soon became the owner of Sado Island.

As one of the "five elders" after the death of Toyotomi Hideyoshi in the future, Uesugi's family governor, Uesugi Kagekatsu, is not weak in theory, but in the eyes of Gao Yushi, his strength is not a threat to Jinghua - anyway, what Gao Yushi wants is Sado Island, it's not to get rid of the Uesugi family.

Since it is just an island, under the blockade of the maritime power of the Maritime Trade Alliance, the Uesugi family's land power is nothing more than a piece of shit, not to mention that the Uesugi family has been in civil strife since the "Dragon of Echigo" Uesugi Kenshin died of drinking too much It's been a few years, and it's just settled down now.

A few years ago, Toyotomi Hideyoshi, in order to win the Uesugi family to assist him in the decisive battle with Shibata Katsuie, allowed the Uesugi family to "take the country freely". However, the Uesugi family didn't dare to do anything, so that Toyotomi Hideyoshi was very annoyed later, thinking that Uesugi Jingsheng broke the alliance and broke the contract.

In fact, it was not that the Uesugi family didn't want to be able to go to the country at the time, but that they really didn't have the ability.Now, although the rebellion of the Shinbata family was finally suppressed, Toyotomi Hideyoshi's Odawara conquest order was also issued, and the Uesugi family sent troops to help attack the Hojo family.

When Toyotomi Hideyoshi launched the Korean War, Uesugi Kagekatsu also sent 5000 troops to Nagoya (northern Kyushu Island, the base camp for crossing the sea), but he did not participate in any fierce battles. Instead, he was mainly responsible for providing troops from the territory. funding.

Although it was for logistics, and the Korean War also failed, after the war, Uesugi Kagekatsu still won the award and moved it to Aizu, jumping from 90 koku in Echigo and Sado to 120 million koku in Aizu.

In any case, there was no ZTE in the subsequent Uesugi family anyway, and later became the number one target of Tokugawa Ieyasu's troubles.All in all, the Uesugi family is a famous name with limited strength, and it cannot threaten the Maritime Trade Alliance at all.

Of course, if you really want to occupy Sado Island, you don’t have to worry about Uesugi’s family, but you have to worry about Toyotomi Hideyoshi’s reaction—it’s not because he’s afraid of anything else, but because he’s afraid that he’ll change his plan, which will frustrate Gao Yushi’s plan. Do not follow the change.

Therefore, regarding the matter of Sado Island, it was just a matter of being pragmatic, just in case, and he would only take action if he was really short of money, otherwise he would not stimulate Toyotomi Hideyoshi and others now.

The big thing he really mentioned was to find the Hojo family to rent half of the Miura Peninsula.

Some people may not be familiar with the Miura Peninsula, but if you say "Yokosuka", there are probably few people who have never heard of it.Gao Yushi wanted to lease the Miura Peninsula, and he was also aiming at the Yokosuka Naval Port of later generations.

The Yokosuka area is located in Tokyo Bay in later generations. Of course, even Tokyo is still called Edo, so there is no such term.The current Tokyo Bay is called "Uraga Waterway", and "Ura" is this Ura on the Miura Peninsula.

However, the Yokosuka Naval Port in later generations was divided into several areas, among which the "Honko Area" was located in the north.Gao Wushi felt that if he proposed to include the "Great Yokosuka" including the Hong Kong area, it would be difficult for the Hojo family to agree because it would mean including most of the Miura Peninsula.

However, there was a city at the southernmost tip of the Miura Peninsula at this time. The city was called Misaki Castle, and there was also a good port here.

Misaki City and Misaki Port are geographically advantageous for Jinghua. Once the fleet is stationed here, it can control Tokyo Bay to the east (Note: I will use this name in the future, after all, everyone is more familiar), To the west, you can look after Sagami Bay.

Of course, there is a premise that Jinghua may need to send army troops as the land defense force for Misaki Castle.

In fact, if the high-practical goal is smaller, it is not impossible not to station the army, because there is a not-so-small island at the southernmost tip of this place, called "The Island of Misaki Castle".

The island is quite large, but even in later generations, the population was not large, because it was not suitable for cultivation.There is a very famous scenic spot on this island called "Horseback Rock". From this name, it is known that the edge of the island is full of rocks.

The edge of the island is full of reef-like rocks, and the middle is hilly. The altitude is relatively high and the view is good, so it naturally means that it is very suitable for defense, especially when Jinghua has enough sea power.

[Note: In order to write this paragraph, I searched for aerial photography of Misaki Castle Island for a long time.According to the video and photos, assuming that the food is guaranteed by sea, at least [-] troops can be stationed on this island.Since the island is similar to a hilly landform except for the edge, theoretically there should be fresh water.

It is suitable for the fleet to berth in the hinterland of the north of the island, which is the side facing Misaki Castle.In the aerial video, there is a bridge connecting here, which is also the closest to the peninsula.Since I couldn't find any information, I had to check it visually, and the distance may be about three or four kilometers.Based on Jinghua's current artillery level at this distance, coastal defense artillery can be installed to prevent the concentration of troops on the beachhead on the opposite bank. ]
However, considering that Jinghua's grain production area is too far away, if the food supply of the base there is completely solved by transportation, it is not cost-effective after all. Therefore, Gao Wushi only planned the city island as the minimum requirement. In the negotiation with the Hojo family In China, we still have to try our best to win half of the Miura Peninsula, or at least we have to win Misaki Castle and its surrounding areas.

In this way, Misaki Castle can serve as Jinghua's fulcrum in eastern Japan, forming a dual control with the Shimadzu family.As for the island of Misaki Castle, it can be used as a place of retreat in case of a strong land attack, and it can be used as the last stronghold, and it can definitely stand firm and wait for help.

The Battle of Odawara lasted for about half a year. If there is no deviation in history, it should end around July next year when Hojo Ujimasa and Uji Teru were required to perform seppuku, and Ujizhi was exiled to Koyasan.

In other words, there is still more than half a year left.However, apart from the time for Gao Wushi to send envoys, contact the Hojo family, negotiate, and hand over Misaki Castle, it can no longer be delayed casually.

After all, although this battle has been fought for so long, Toyotomi Hideyoshi's conquest of the Hojo family was not the only battle in Odawara. If it was delayed for a long time, it would be very embarrassing for the place to be taken by Toyotomi Hideyoshi or his affiliated forces in advance.

At this time the night was getting dark, Gao Wushi also dragged Huang Zhiting to the study.The two discussed for a while in front of the map, and Huang Zhiting made an analysis with a more professional tactical perspective, and even determined the division of the defense zones, which saved Gao Pragmatic a lot of trouble.

But after that, Huang Zhiting was a little worried, saying: "If the handover of this city and the island is smooth, and there is a one or two month deployment time, the problem of city defense and island defense is not serious, but there are still two points worthy of attention. .

One is that if we want to ensure the stability of the city defense, not only the Misaki City in this area may need to be expanded, but we also need the land division to fortify north and build at least two lines of defense.

I don't know the combat effectiveness of the Japanese army. Assuming that their level is similar to that of the Burmese army at the time, in terms of the terrain of the peninsula, we need to maintain at least 1 troops for defense-this is when the enemy sends 3 people to attack. The premise.If the opponent dispatches [-] or more troops, we'd better ensure that [-] to [-] troops are stationed in Misaki City. "

Gao Wushi scratched his head and said, "Toyotomi Hideyoshi dispatched an army of 30 to attack the Hojo Clan. In addition, the strength of the Japanese army... as a whole must be stronger than that of Myanmar."

Huang Zhiting said "Oh", looked at the map again, and said after a little thought: "It's okay, the area in the south of the Miura Peninsula that the master is looking at is less than eight miles away at the narrowest point.

Not to mention that it is impossible for Toyotomi Hideyoshi to attack a Misaki Castle with an army of 30. Even if he does come, the force will not be spread out, and only a few people can be invested.

Our army occupies this hilly mountain (she doesn't know the name of the mountain, it is called Paotai Mountain in later generations), the western plain can be blocked by the fleet on the one hand, and the army on the other hand can be guarded or deterred; the coastal plain area on the east is narrower and easier to defend .

From this point of view, the enemy can only forcibly pull out the stronghold on the mountain.Under the premise that our army has the superiority in firepower, this difficulty...it would be very difficult for me to command, and it would have to be filled with human lives.Therefore, although this mountain is not big, but there are not [-] corpses, it is definitely impossible to exchange. "

Gao Wushi smiled and said: "The first line of defense will lose 2 people. I don't think Toyotomi Hideyoshi may be happy."

Huang Zhiting did not answer, but talked about the second line of defense, pointing to the "gap" on the peninsula called "Xiao Tsunashiro Bay" in later generations, and said: "This is not far from Misaki City, it is the last line of defense in the outer city area. A field line of defense is only about five miles wide, and there are dense forests to the west, no matter whether there are mountains or not, it should be easy to defend; the east is a plain, or there may be a lot of fields, generally speaking, it is most likely to break out a decisive battle... "

Gao Yushi frowned slightly, and before he could speak, Huang Zhiting chuckled, "But at this distance, naval guns can cover almost all of it. If anyone really wants to fight our army here, I suggest them Find some monks and priests in advance, and prepare to perform deeds."

Gao Wushi laughed, and nodded after a long time: "In this case, my husband will send someone to inform the Japanese fleet tomorrow, and ask them to go to Kanto to get in touch with Hojo's family after they' patrolled Kyushu Island."

Huang Zhiting nodded, and reminded: "Since the master has decided, I won't say much. But the master should make an inventory of Master Lu first, so as not to be in a hurry. In addition, the Japanese side is a bit far away. If there is any unexpected situation, I am afraid it will be difficult to ask for instructions and receive orders in a timely manner. My concubine suggests that it is best to choose a person in charge who has an overall view, and give him a certain amount of autonomy to facilitate his actions."
