Li Tangshan: "Although the military Fan Zeng suggested that Xiang Yu first fight Wang Li in the north, and then fight Zhang Han in the south. Fan Zeng's idea was to first annihilate the Qin army's naval division, then compress the Great Wall army to a narrow area by the Qingzhang River in the east of Julu City, and then the Chu army from the south to the north, and the princes' coalition army from the north to the south to surround Wang Li's army. Although the benefits have been obtained, there are still three difficulties in front of Xiang Yu? ”

Panli was surprised and said, "There are still three major difficulties? ”

Li Tangshan nodded: "The first major difficulty is how to reach Julu City safely?" You have to cross the river first, and to cross the river first, you have to have a sailor. ”

Pan Li asked, "What is the second difficulty?" ”

Li Tangshan: "The second major difficulty is how to separate Wang Lijun from Zhang Hanjun? At this time, Zhang Han's army was in Pingxiang, and Wang Li's army was only half a day's journey from the two armies under Julu City, and if he wanted to separate them, he had to separate the two armies for at least 3 days. The most direct way is to attack Zhanghan's southern base camp: Thorn Plain, and force the army on the front line of Zhang Han to defend from Julu City to Thorn Plain. Then the Chu army went to attack the inner Yongdao of the sand dunes, because it was not only the grain and grass of the Qin army, but also the front-line command post of the Qin army. This is difficult, because Xiang Yu's Chu army is still in Anyang at this time, and it is still far away from Julu, and can the Chu army's combat strength defeat the Great Wall Army of the Great Qin Empire? ”

Pan Li: "The third difficulty? ”

Li Tangshan: "This difficulty is the most difficult for Xiang Yu to solve, appeal!" How to persuade the princes in the north of Julu City to listen to Xiang Yu and surround Wang Li together. This is even more difficult, because Xiang Yu was only 26 years old at this time, and he was simply a "nobody". ”

Pan Li: "That big difficulty is difficult, let alone the three major difficulties? ”

Li Tangshan nodded: "This is war, you live and die, not a game of playing house." ”

Panli asked Li Tangshan again: "Husband, how do you think Xiang Yu will solve these problems?" ”

Li Tangshan: "Julu County is actually a barrier in the core area of the Chu people, don't underestimate Xiang Yu, the battle of Julu will definitely become a big stage for Xiang Yu's rise." You can think about it, if you were Xiang Yu and took command, what would you do? ”

Pan Li simply replied: "If it were my Xiang Yu, he would definitely continue to march north to the Yellow River, the supplies of the Qin army almost all relied on the Yellow River for water transportation, but it was impossible for the army to be stationed by the Yellow River." Therefore, a grain transportation channel was built in the distance from the river bank to the camp. In the face of the surprise attack launched by the Chu people with superior forces, the Qin army guarding these narrow passages was powerless to stop them. When Wang Li's army began to starve, Xiang Yu led all the main forces to continue to advance. ”

Li Tangshan nodded: "I also think that after getting the command, Xiang Yu continued to march north to the plain on the bank of the Yellow River, and then joined the reinforcements of the Qi State. ”

Pan Li: "Husband, no, Xiang Yu doesn't have any sailors?" Although there are still sailors of the Qi army on the Yellow River, they are only transport teams, and they are all very weak. ”

Li Tangshan: "Because of the lack of boats, all Xiang Yu did not rush to cross the river, and shipbuilding was much easier for the Chu people in Jianghuai than other countries. ”

Pan Li said worriedly: "But there are patrolling Qin army sailors on the Yellow River, as long as the Qin army sailors are there, they will not let the Chu army build ships leisurely." On the other hand, the Qin army had a very large naval division force, and the number of ships was much larger than that of the Chuqi naval division. ”

Li Tangshan: "So Xiang Yu must build a ship first, but at the same time as building a ship, Xiang Yu sent a cavalry unit to make a detour from the territory of Wei to attack Huaxian. The leader of the troops was General Pu. General Pu set off with the Qi army's naval division, which had just arrived, preparing to attack the Qin army's important ports by land and water. ”

Panli clapped his hands and said: "This trick is wonderful, Zhang Han didn't expect that the first target of the Chu army was Huaxian, and Zhang Han must have been unprepared." It is conceivable that he was caught off guard by the cavalry of the Chu army, and not only lost an important port, but also the fleet in the port was basically annihilated. ”

Li Tangshan: "Yes! More importantly, if Huaxian fell into the hands of the Chu army, then the connection between the Qin army north of the Yellow River and the area south of the Yellow River in the east of Dongjun would be cut off, and the supply line of the Qin army from the east of the entire Zhao land would also be cut off. The war could only be sustained by supply lines from the western capitals of Xianyang and Aocang. ”

Pan Li: "Huaxian is so important, how could Zhang Han easily give it to Xiang Yu." Therefore, the Qin army must recapture Huaxian, Zhang Han was forced to mobilize ships further west due to the situation that there were no ships to adjust in the area east of Huaxian, and even the sailor troops defending Aocang were also transferred, and it was the general Sima Xin who led the troops to recapture Huaxian, but at this time, the cavalry troops of the Chu army and the water division of the Qi State had directly retreated to Pingyuanjin, because the goal of the coalition army was obviously to annihilate the sailors of the Qin army, so that the Qin army in Zhao would lack supplies from the east. ”

Li Tangshan gave a thumbs up to Panli and said, "Madam, smart! Therefore, when the Qin army's naval division arrived in Huaxian, it was long gone, and the coalition army was long gone. In the end, all Zhang Han could do was to put the newly assembled sailors back in the port of Huaxian County and continue to serve as a transport force. But at this time, the news came that the Chu army had been found on the Zhanghe River north of the Thorn Plains, his big rear. ”

After getting Li Tangshan's affirmation, Panli said happily: "In fact, Xiang Yu's combat intention is to separate Wang Li and Zhang Han, and to separate the two, you must attack Zhang Han's big rear, the Thorn Plain. Because only by attacking this place can it be possible to lead Zhang Han in Qiu County to rescue. Xiang Yu is really powerful. ”

Li Tangshan: "Of course, the overlord of Western Chu is not called in vain. If you want to attack Jianyuan, you must first annihilate Zhang Han's naval division on the Zhanghe River, but the Qin army's naval division is composed of a large number of warships, but to maintain a long supply line from the east and west, the number of warships is too scattered, and the land troops defending Huaxian County can't think of anyone coming to attack here, so after the Chu army succeeds in the sneak attack on Huaxian, most of the ships of the Qin army's naval division have been annihilated, and the rest still need to continue to transport grain and grass, so that the Chu army has created time for building sailor warships. ”

Pan Centrifugal couldn't help but admire Xiang Yu: "Amazing! What a military genius! Wang Li can't play Xiang Yu this time, and even Zhang Han is not an opponent. ”

Li Tangshan: "After having a water division, he immediately crossed the Yellow River, and then entered the Wei River valley along the Yellow River, and chose Guantao as the second attack point, because Guantao also had a naval base of the Qin army.

And Zhang Han still didn't expect that the second attack point of the Chu army was actually Guantao. After capturing the base of Guantao's sailors, Xiang Yu's Chu army captured a large number of warships. After that, the Chu army then took a warship to the south along the Zhanghe River in Guantao, preparing to cross the south bank of the Zhanghe River and land to attack Zhanghan's rear base camp - Thorn Plain.

And the gains and losses of Thorn Plains are related to the overall situation, because at this time, the supply line of Huaxian County in the east has not been repaired, if the Thorn Plains are lost again, the 400,000 Qin troops will not only be cut off from retreat, but will also fall into a situation of running out of food. So at this time, Zhang Han could only lead the whole army south to return to the Thorn Plain, and what Xiang Yu was waiting for was Zhang Han's return to the Thorn Plain. ”

Pan Li: "Why did Xiang Yu have to wait for Zhang Han's return to the Thorn Plain?" ”
