In early July, the land in Liaodong was steaming, and the weather was hot. Affected by the small glacier climate, the Liaohe Plain was extremely dry this year. There was almost no rain in June, which was originally full of rainfall. Even the runoff of the Liaohe River was significantly reduced, and large swathes of tidal flats were exposed. Out of the water, there were small fish and shrimps that had dried up and turned into mud.
Thanks to Emperor Wuding's heavy investment in Tunpu agriculture when he was stationed in Liaodong, water conservancy on both sides of the Liaohe River was quite complete, and all kinds of irrigation equipment were readily available. Especially in the third year of Taichang, Xu Guangqi and Jinnige invented and popularized the dragon tail car. Using this sharp tool to draw river water to irrigate crops is ten times more efficient than the previously used keel cart. It is said that this kind of irrigation tool uses the principle of Archimedes' spiral motion. It uses spiral transportation, and uses the rotation of the internal shaft to drive the spiral blades to run in the opposite direction, moving the water upward to achieve the purpose of raising water.
In addition, Emperor Wuding spent a lot of money on the construction and maintenance of farmland ditches. During Liu Zhaosun's six years in Liaodong, he invested more than 100,000 taels in farmland water conservancy tools and seeds every year.
Real money investment, a relatively stable farming environment, scientific and reasonable fertilization and irrigation, the continuous introduction of high-yielding crops (upland rice, sweet potatoes, lodging-resistant corn, alfalfa), and of course an efficient and clean civil affairs official system. Under the superposition of various factors, From the forty-seventh year of Wanli to the first year of Wuding (1619-1626), most of the grain produced every year in the forts in Liaodong was transported to various granaries for storage...
In the first year of Wuding, the spring wheat growing on the Liaohe Plain was not only not affected by the harsh climate, but also grew more gratifyingly because of sufficient sunlight.
In early May, after Qiao Yiqi, Xu Guangqi and others fled back to Liaodong, Xu Guangqi suggested that Xie Yang immediately start transporting grain to several major cities in Shenyang and Liaoyang, just in case. Although Xie Guangkun was not an army officer and did not know how to march and fight, he saw with his own eyes that the emperor was besieged by hundreds of thousands of bandits in the capital. At this time, even a fool knew that Da Qi's withdrawal to Liaodong was a certainty, so this The chief civil affairs officer failed to petition the emperor - there was no way to do so at that time - so he ordered the civil affairs officers and commanders of various villages to start transporting grain. Only twenty days of rations were left for the garrison, and all other grain and grass were transported to the great city of Liaoshen.
In this way, by the end of May, all the food in the cities and villages in Liaodong was gradually transported, and even the people and merchants began to evacuate in batches - the vast majority of Liao merchants voluntarily went to Shenyang, but only a few were reluctant to part with their property and fields and were willing to stay. Waiting to die.
Since the Daqi troops stationed in various places have been stationary, some cities even have a tendency to gradually increase their troops. In order to confuse Jianzhou North Korea, Qi Jin sent additional troops to Fushun near Hetuala and Kuandian near North Korea. Jianzhou North Korea He did not dare to act rashly for the time being, especially in Du Du's view, the traces of the Qi army were quite suspicious. After all, this kind of behavior of not plundering the people and escaping, but letting the merchants retreat first, was not something that the Qing Emperor could understand by people like Du Du. .
At the same time, the two surviving Kaiyuan chambers of commerce in Shandong and Liaonan purchased grain from various places in Nanzhi at high prices. Although the Nanming court repeatedly issued orders strictly prohibiting the smuggling of grain to Qi, many bold businessmen still took risks driven by profit. ······By the time the war officially started between the two sides, Shenyang, Liaoyang Tieling and other cities had already stocked up an astonishing amount of grain, grass, gunpowder and other military supplies.
It was not until the last batch of farmers in Fushun and Kuandian had finished harvesting the spring wheat and corn that Emperor Kangxi and Qianlong finally realized that something was wrong. He ordered Dorgon Aobai and others to set fire to the fields in various places in Liaodong and burn them down. The crops cultivated in the fort were used to weaken Da Qi's war potential as much as possible, but by this time it was already too late.
The ferocious Oboi was surprised to find that before the Eight Banners warriors could take action, Liu Zhaosun's disciples and grandsons had already taken a step ahead of them and burned everything that could be burned in Fushun, Kuandian and other cities, and smashed everything that could be smashed. Not a grain of rice, not a pound of gunpowder, not even an arrow cluster was left to me in the Qing Dynasty.
Not only that, the cunning and vicious coir raincoat guards also poisoned wells everywhere, and even the few pastures were poisoned by them. From time to time, there would be a deadly mine cannon or bamboo poles planted on the avenues where people passed through in the city. The trap of the lottery is waiting for the Eight Banners warriors to take risks and conquer.
Emperor Wu Ding had been operating in various places in Liaodong for a long enough time, and the espionage network was strong enough. In addition, Shen Lian, Zhang Dong (both of whom were killed in battle), and Liu Xingzuo led the raincoat guards who tirelessly carried out counter-espionage operations in various places. Du Du The fine works installed in various cities in Liaodong will be cleaned by the coir raincoat guards basically every half a month. Fortunately, our Qing Dynasty (formerly known as Jianzhou) has never been short of coatings, so these spies are like leeks in winter, cutting one wave and then growing another wave, and growing one wave and then cutting off another wave. In the end, the two sides reached a tacit agreement, and Du Du consciously sent those prisoners (political opponents) who had committed capital crimes but did not need to do it themselves to the boundaries of the Capry Guards. The name was to spy on military intelligence, but in reality it was just to kill people with a borrowed knife.
In short, in the first year of Wuding, during Liu Kan's reign, the decisive battle that determined the life and death of the Qi Dynasty was completely different from the bloody battle of Hunhe River fought by his father, Liu Zhaosun, and the subsequent Battle of Hetuala. Qi Jun is no longer in the same state as before, where he went up to fight the enemy to the death with his eyes darkened.
In the words of Kang Yingqian and Qi Jin, the little emperor has God's blessing. The Qi army is well aware of the attack of Jiannu. In addition to military strength, our army has an absolute advantage and will win this battle. Qi Jin required that every soldier of the Qi army must kill or injure more than ten Jian slaves in the battle to defend Liao and Shen before he could die, otherwise he would be suspected of collaborating with the enemy...
