Luo Xian's chosen place to cross the river was Guangwudu in the south of Huai County, which was named after the city of Guangwu on the south bank of the Yellow River. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

When it comes to Guangwu City, it is famous and known all over the world. The ancient city of Guangwu is located on the Guangwu Mountain, divided into two cities, east and west, and there is a deep stream in the middle, which is the confrontation place between Liu Bang and Xiang Yu in those years.

Guangwu Mountain is steep from the riverside, from north to south, continuous, the peaks and peaks are sharp, the steep pull is dozens of zhang, the morning glow and twilight smoke, the metamorphosis is ten thousand. To the north, the Yellow River clings to the foot of the mountain; In the southwest, thousands of mountains are wrong, and the peaks are towering. Here, not only the valley is deep and steep, the cliff is uneven, and there is the danger of Chenggao in the west, there is the millet of Aocang in the northeast, and there is the important town of Xingyang in the south, which is the throat of the ancient traffic and the place where the soldiers must fight.

When Chu and Han fought each other, the Han army took advantage of Xiang Yu's eastward attack to seize Chenggao, and then stationed troops to block Chu's westward advance. Xiang Yu, the king of Chu, hurriedly led his troops to the west, and also stationed troops in Guangwu, and the Han army across the stream to confront, the two armies fought here repeatedly, holding each other for several months, and finally because of the lack of food in the Chu army, the army was disheartened, and Han Xin also sent troops to attack Chu, Xiang Yu was forced to make peace with the Han Dynasty, and divided the world in the "chasm" (that is, Guangwu Stream) as the boundary. The "Chu River and Han Boundary" on the Chinese chessboard refers to this chasm.

Lu Kang marched west along the Yellow River, naturally it was impossible not to consider the threat of the Han army on the north bank of the Yellow River, but the Yellow River thousands of miles of defense line, Lu Kang could not predict that the Han army would cross the river from that ferry, if the comprehensive defense along the river, the strength of the Wu army was insufficient, not to mention that the main offensive target of Lu Kang was Luoyang, for the enemy on the north bank of the Yellow River, it could only be a little precautionary, and heavy troops were deployed in several important places to defend, such as Tiger Pass and Xingyang, which were important towns on the east-west passage, so they naturally had to focus on defense.

Moreover, Xingyang is the place where the Wu army stores grain, and the grain and grass mobilized by the Wu army from all over the country are concentrated in Xingyang, and then transferred to the front line, the importance of Xingyang is naturally self-evident.

If the Han army takes Xingyang, the Wu army is not only cut off from retreating, once the supply of grain and grass is lost, the Wu army will be in chaos.

However, Lu Kang could not pay attention to the defense of Xingyang, the Yellow River defense line was too long, and the Wu army had limited strength to take care of it, but to hold the city of Xingyang, Lu Kang was confident and sure.

Lu Kang arranged for Pingdong General Zhang Xiang to be the general of Xingyang, and Pingkou General Cai Min led 30,000 troops to garrison Xingyang, and the Tiger Pass and Xingyang were not far away.

After receiving the order, Luo Xian immediately arranged for the operation of crossing the river.

Since it was determined that he wanted to cross the river from Guangwu, Luo Xian first sent scouts to cross the river overnight in small boats to find out the situation on the south bank.

The scouts quickly sent back the news on the other side of the river, the Wu army was trapped by the lack of troops, and could only focus on the defense of Xingyang and Hujiao, as for Guangwu on the south bank of the Yellow River, the Wu people did not send any men and horses to garrison at all, but left a patrol team of dozens of people.

Luo Xian laughed and said, "God help me!" So he ordered an elite team of scouts to be sent over, first to kill this patrol of the Wu people, and then to mobilize ferries to transport men and horses across the river day and night.

Zhang Xiang sent a patrol team to monitor the movements of the Han army on the south bank of the Yellow River, with these dozens of people, of course, it could not be stopped, but Zhang Xiang could grasp the movements of the Han army in the first time, so as to prepare a countermeasure.

Luo Xian naturally could not let the Wu people grasp their own movements, and when he detected that the Wu army had a patrol post on the south bank, he first sent someone to kill this patrol team, and then Zhang Xiang became blind and knew nothing about the Han army's river crossing operation.

Although there was no Wu army to stop it, the right army was all cavalry, and it took much longer to cross the Yellow River.

In the past two days, Wu's army has advanced eighty miles from the Tiger Prison Pass, and can already see the towering city walls of Luoyang City in the distance.

After Luo Xian assembled the army in Guangwu City, the troops were divided into three routes, the east route was led by Lu Xun to lead the Suzaku Army to Longcheng to cut off the enemy retreat to the east of Xingyang, and the west route was led by Deng Pu to lead the Qinglong Army, capture Yuting, cut off the contact between Xingyang and the Tiger Prison, and Luo Xian personally led the White Tiger Army, Xuanwu Army, and Qilin Army in the middle to take Xingyang.

The right legion is all cavalry team, the momentum is extremely fast, ten thousand cavalry are crowded, the momentum is monstrous, Xingyang guard general Zhang Xiang heard that the Han army has crossed the Yellow River to Xingyang to kill, immediately a little panicked, hurriedly discussed with the deputy general Cai Min: "The Shu people are menacing, how should this be good?" ”

Cai Min said: "Although the Shu people are numerous, but all are cavalry, cavalry is conducive to field battles and not conducive to siege, we only need to defend and refuse to fight, and quickly send someone to notify General Wu stationed in Hujiao Pass to come to reinforcements, or report to Lu Da Sima, we only need to hold on for a few days, when the reinforcements arrive, the siege of Xingyang can be solved." ”

Zhang Xiang also knew very well the strength of the Han cavalry, how dare to go out of the city to fight, and immediately ordered all the troops stationed in Xingyang to go to the city to defend the palace, the city gate was closed, the drawbridge was hanging, and no one was allowed to go out of the city to fight without his order.

On the other hand, Zhang Xiang quickly asked for help from Wu Yan, the general of the Tiger Prison, and sent a fast horse to report to Lu Kang.

Xingyang City is the place where the Wu army is stocked with grain, the grain and grass collected from all over the place are first gathered in Xingyang, and then transferred from Xingyang to the outside, the grain and grass required by the 200,000 army is a huge number, in order to ensure that the grain and grass are not lost, Lu Kang arranged heavy troops in Xingyang to guard.

Under normal circumstances, the army's grain storage places are placed in places where the terrain is dangerous and the water and land are to be rushed, in order to facilitate transshipment, but Lu Kang knows that the Han cavalry is powerful, if the grain storage is arranged in the field, how to defend against the attack of the Han cavalry is a headache, so Lu Kang thought about it again and again, and chose Xingyang City as the place to store grain.

Xingyang City is an important town, the city wall is strong, the fortifications are complete, like such a strong city, even if it is a special siege force to attack, it will take a lot of effort, if it is a cavalry force, it can only be a sigh of hope.

Secondly, Xingyang is relatively close to Luoyang, and the Wu army can effectively shorten the distance of grain and grass transportation by gathering grain and grass here, so as to prevent the Han army from attacking the grain transport team on the way.

The most important thing is that Xingyang is very close to the large army, and in case of emergency, the large army can be reinforced at any time.
