Whether in ancient times or in modern times, the most important premise of marching and fighting a war is to have enough food, enough military expenditure, and enough ordnance, and these three most important components of waging war and conducting war are actually the embodiment of logistics, so there is such a saying that fighting a war is to fight logistics, although such a statement is biased, but once the two armies of two countries are inseparable, logistics will often become the decisive factor.

In ancient times, limited to the level of productive forces, the amount of grain reserves was generally not very large, no matter how large and rich the country was, it was the same, and the number of strategic grain reserves of the country that could be used by the army for war would not exceed one year at most, because grain first had a storage period, and the problem of harvest should also be taken into account, and this was still a situation where only one army fought a war and not several battlefields were opened up at the same time.

The reason why the ancient art of war taboos two-front warfare is that there is a lack of food supply in it, there is no better means of storing grain and enough food, and they do not dare to fight at all.

Goguryeo was not a very big country in the first place, Rao is a big country like the Tang Dynasty, so much territory and arable land, in the first few years before getting the seeds of high-yield crops, it still did not have the confidence to wage war against Xue Yantuo and the Western Turks at the same time, otherwise Zhenguan could start a war in five or six years, and it was not without corresponding considerations at that time. However, after Li Ermajesty summoned the officials of the Ministry of Civil Affairs to settle an account, he depressedly dispelled such an idea.

Not to mention the Western Turks, even Xue Yantuo can't fight, the grain reserves in the late Wude period and the first four years of Zhenguan were basically consumed by the Eastern Turkic War in the four years of Zhenguan, and the battle of Lingzhou that followed was bigger and bigger, and a lot of food was also consumed, so that when the potatoes and rice were just obtained, the Tang Dynasty was in a situation where the grain was about to bottom out, so Li Erqi was so excited, it was not only for the long run. There are also thoughts for the present.

After that, the situation stabilized. After the start of the Jiangnan Rise Plan, grain cultivation in Yangzhou and Jingzhou began to be fruitful in two quarters a year. After that, it was a great success. Only then did it gradually begin to promote planting in Jiangnan. The food crisis was gradually resolved after the expansion of the planting area and the target audience in the Guanzhong area, and then with the development of the commodity economy and the abundance of money. Li Ermajesty spent a lot of money to pull agriculture up, and the grain reserves of the Tang Dynasty returned to the level of Zhenguan for four years after Zhenguan's six years.

But as long as you endure the most difficult period, the next will be easy, Zhenguan six years, seven years, eight years, nine years and four years of bumper harvests, grain output is higher and higher year by year, Zhenguan eight years, nine years and two years of grain production is to put hundreds of strategic grain reserve warehouses in the Tang Dynasty to the full, several large granaries around Chang'an City are rising, so that there can be a lot of wealth, potatoes and rice piles everywhere, Huang Chengcheng and a piece of gold is particularly gratifying.

Under such circumstances, in the tenth year of Zhenguan, as the problems in the south of the Yangtze River were gradually sorted out by Suning, the finances were abundant, the food was sufficient, the reform plans were steadily advanced, and the internal stability was basically stable, Li Erma put forward the strategic idea of solving Xue Yantuo and the Western Turks, and authorized the General Staff Headquarters to plan the entire battle with full powers, eliminate Xue Yantuo and the Western Turks in one fell swoop, completely sweep away the northern border troubles, and lay the foundation for the next step of the strategy of the eastward crusade and westward advance.

With the support of such abundant and strong national strength, Datang has the confidence to launch the grassland battle, and has the confidence to open up two battlefields, which are carried out at the same time, the battlefield of Goguryeo is unexpected, and it is very difficult for Datang to support at the beginning, with the implementation of Suning's surprise attack strategy, the crisis has been lifted, and Datang has demonstrated a strong war potential with the support of abundant national strength and sufficient population, and in just over three months, the enlistment plan of 200,000 recruits has been basically completed. Graduates of military universities were also sent to the recruit corps as junior officers and grew up with the recruits.

Compared with the Tang Dynasty's easy war force, Goguryeo is weak and powerless, the domestic people are severely wounded and starved for thousands of miles, basically in a state of exhaustion and fishing, leading donkeys to quench thirst, the three major forces continue to recruit and prepare for war, young and strong men are no longer there to start against other men, men really have no way to go to the battlefield to start from strong women, and organize a lot of women's special teams.

The men are used up, only the women are left, and the children are basically almost dead, there is not a single infant in a thousand people, the problem of offspring is worrying, this generation is gone, how many people will grow up in the next generation? The young people were all dragged out to serve as soldiers, and then died quickly, and there was no chance to create the next generation, and the population of Goguryeo was sharply reduced and even the entire ethnic group was wiped out.

And with the hot climate, another problem that cannot be ignored appeared, on the 16th day of the seventh month of the 10th year of Zhenguan, a lot of information suddenly came from the blood droplets hidden in various parts of Goguryeo, and these information were surprisingly consistent, after comprehensive judgment, Suning can determine that there was a plague in Goguryeo on the north bank of the Daedong River and the original Goguryeo territory on the south bank of the Daedong River.

Marching and fighting inevitably kills, and the corpses of the dead will rot and produce bacteria, especially when the weather is hot, the decay rate of the corpses will be accelerated, and the plague will inevitably arise, so after the ancients learned this, they would cremate or bury the corpses immediately after the war to avoid the emergence of plague.

And in this battle that affected the entire Liaodong and most of the Korean Peninsula, except for the Tang Dynasty consciously disposed of all the corpses in the cold season, there were few people in the entire Goguryeo except for Quangae Suwen, or they were interrupted by the war before they could do so, from the beginning of the war five months ago to the present, the entire Goguryeo has not exceeded the 20-day truce, and it always stopped and began to fight within a few days.

Now there are only three factions, so the truce period is slightly longer, compared to before. There is no such statement at all, more than 50 local powerful factions are nesting in such a small place, today you beat me tomorrow I will beat you, after the fight, the corpses are all over the field, and before the clean-up is completed, the others will call again, how can there be time to clean up the corpses?

The corpse didn't have time to clean up, so it was left there, it was fine when it was cold, but when it was hot, the corpse decomposed faster. Where there is a dense concentration of corpses. The stench could be smelled for miles away, and it was even more inaccessible, and the entire area was a dead area, and there were few living creatures to be seen.

It's not the deadliest. There is no one living in a place where there are many dead people. The population of Goguryeo was now mainly concentrated in the centers of several powers. In remote areas, there is no one except for the border guards, there is no one for thousands of miles, and the epidemic cannot be transmitted. It is fatal to die in the vicinity of the water, and even in the upper reaches of the water, which means hundreds of thousands, and after all of them die, the corpses are either in the water or at the edge of the water, and at first it is fine, but gradually the corpses decompose, and a large number of bacteria that cannot be seen by the naked eye enter the water source, and slowly move towards the populated areas as the river slowly moves.

As a result, the Goguryeo people did not have the habit of not drinking raw and dirty water from the Tang Dynasty now, and they must drink boiled clear water if they want to drink it, and the bacterial incubation period passed, with the arrival of a hot summer that was short and hot, the plague had already been determined but broke out without warning, and the people around several major water sources all got the plague, and the main road of the Datong River because of the large water flow, the defense corps that lived on the water source of the main road had nothing to do, but the people living around the tributaries suffered.

Generally speaking, because the Silla people had relatively abundant time and the country was unified, the situation was relatively good, and they organized an epidemic prevention team to start a war against the plague at the first time of the outbreak of the plague, and they also began to drink boiling water instead of raw water, and drank water far away from the epidemic area instead of drinking the water from the epidemic area, and isolated the epidemic area and burned the corpses, but on the contrary, the spread of the plague was controlled, and the safety of the Silla people was guaranteed.

But the Goguryeo people, the Goguryeo people on the north bank of the Daedong River were miserable, and the three major forces that were still in a state of confrontation with each other and a state of imminent war were attacked by the plague without warning, and the ferocity of the attack was unprecedented, from the first person with high fever to the first person died, it only took half a day, half a day before only one person had symptoms, and after half a day, not only were all patients, but the dead also appeared.

This time the plague came more ferociously and harshly, much more powerful than the original plague of Datang, Datang's strong medical strength and Suning's strict orders and the complete cooperation of the army, and there were still 10,000 people killed under the three-pronged approach, not to mention the three major forces of Goguryeo, which had no time and preparation for epidemic prevention at all.

Quangai Suwen is okay, there are many troops, there is time to clean up the corpses, and the awareness of disaster prevention is relatively heavy, the initial outbreak point of the plague is not in the territory of Quangai Suwen, but in the territory of Jinsheng, and then the territory of Li Yuenan in the north, the ultimatum guò border regiment infected the territory of Quangai Suwen, Quangai Suwen sent people to isolate the northern border and the southern border for the first time, sent enough crossbowmen, killed people who tried to cross the border, killed I don't know how many people and then burned them down, and finally controlled the spread of the plague again, Saved his lair.

But Jin Sheng and Li Yuenan are different, the flashpoint of Jinsheng's territory is his lair, the flashpoint of Li Yuenan's territory is the northern Great Wall area, which is ferocious, from the occurrence to the large-scale infection for almost a few days, they didn't realize it at all, the reason why Jin Sheng found the plague was that a guard around him suddenly fell to the ground while on duty, and died a day later, which scared him out of his mind, and then he began to pay attention, and then realized that the plague had broken out.

As for Li Yuenan, he received a letter from a team sent to the north to find food, and learned that there was a plague outbreak on the Great Wall in the north, and the population was not one in ten, but when he wanted to stop it, the first wave of plague survivors who fled from the Great Wall into the territory had died, and there were a large number of plague patients in the barracks.

How could the Goguryeo people, who couldn't even get food, still have medicine to treat the plague? Besides, the plague is a killer, don't mention any treatment, curb the spread first, otherwise before you develop a special drug, people will all die, Datang's luck in defeating the plague last time is irreproducible, since then, public safety and health issues have entered the field of vision of Datang's high-level management, and this has begun the collective movement to clean up the garbage of sanitation, which has gradually matured in the past two years.

But this qiē did not appear in Goguryeo, the damned people will still die, and those who will not die may also die, Suning received the information as soon as he strictly ordered the northern garrison corps to block the current Tang-Gao border, and no one from Goguryeo was allowed to enter the territory of the Tang Dynasty, no matter who it was, without explaining the identity of those who tried to cross the border, shoot them directly, and burn the corpses, and the soldiers who came into contact with these people must wear gloves and masks, and then go to the military doctor to wash their hands with wine, and only after getting the permission of the military doctor can they regain their freedom.

Goguryeo suffered, it will not let the Tang people also suffer, there are no people in the Liaodong Peninsula, they are all armies, once infected with the plague, it is too terrible, and there is no special medicine here, Sun Simiao is in the grassland, not to mention the research and treatment of the plague, the Goguryeo people still ask for more blessings!
