Historically, not all of the four crossings of Chishui were actually commanded by Mao Weiren.

The first and second crossings were in fact successfully commanded by several veteran leaders such as Zhou Weiren and Zhu Weiren. Because at that time, Mao Weiren had not yet fully gained the initiative, and was still subject to certain constraints, and his command was not neat. However, the third and fourth crossings were directly commanded by Mao Weiren.

As a matter of fact, as early as after the Zunyi Conference in history, the Central Revolutionary Military Commission issued a "River Crossing Operational Plan" to the commanders of all army corps, drawing up: After the various units of the Central Red Army entered the area near Chishui and Tucheng, they would cross the Yangtze River north in three columns from Lantian Dam, Dadukou, and Jiang'an between Yi (Bin) and Lu (Zhou).

From January 19, 1935, the 1st, 3rd, 5th, and 9th Army Corps of the Red Army set out from Zunyi, Tongzi, and Songkan areas in three directions, and advanced to Tucheng and Chishui. On the 24th, the vanguard Red 1st Army Corps defeated the resistance of the Guizhou army, captured Tucheng, and marched towards Chishui. On the 25th, the Red 3rd Army Corps arrived at Tucheng. On the 26th, the Red 1st Army was blocked by the Sichuan Army's Zhang Anping Brigade and Dafenggang Brigade at Huangpidong and Fuxingchang, and the Red Ninth Army Corps was blocked by Xu Guoxuan's unit of the Sichuan Army's special detachment at Jiantan, and the Red Army's plan to occupy Chishui was frustrated. On the 27th, the Central Military Commission column was stationed in Tucheng. On the 28th, the 3rd and 5th Army Corps of the Red Army, the columns of the Military Commission, the cadre regiments, and the 2nd Division of the 1st Army Corps of the Red Army, which had returned from Bing'an, launched a fierce attack on the Guo Xunqi Brigade and Pan Zuo Brigade of the Sichuan Army in the Tucheng and Qinggangpo areas, and inflicted heavy losses, but the 4 brigades of the follow-up troops of the Sichuan Army were quickly reinforced, and the two sides formed a confrontation situation. On the evening of the 28th, the Politburo and the Military Commission held an emergency meeting and decided to withdraw from Qinggangpo, change the route of the march to the north, and avoid a strong enemy. In the early morning of the 29th, the Red Army divided into three routes, left, center, and right, and crossed the Chishui River from Yuanhou and Tucheng to the west, that is, the first crossing of Chishui in the four crossings.

The main force of the Red Army advanced to the Tashi area, but the enemy still judged that the Red Army would cross the Yangtze River to the north, and in addition to increasing troops at the main ferries in the Yibin section, he also transferred the Yunnan Army and the Pan Wenhua Division of the Sichuan Army to approach the Tashi area, in an attempt to attack the Red Army separately and jointly. In view of the fact that most of the enemy's main force had been attracted by the Red Army to the Sichuan-Yunnan border and that the troops in northern Guizhou were empty, the Red Army decided to return to the east by surprise and turn back to Guizhou. The first regiment of the Red Army rushed to Erlangtan before the enemy, successfully covering the troops to cross the Chishui River for the second time at Taipingdu and Erlangtan from February 18 to 20, and continued to advance in the direction of Tongzi and Zunyi. On the 24th, Tongzi was occupied. On the night of the 25th, they occupied Loushan Pass. On the 27th, the enemy's 3 regiments were defeated at the Dong Gong Ancestral Hall, and on the morning of the 28th, Zunyi City was captured again. At noon on the same day, after the Red Army entered and occupied Laoyashan, Honghuagang, and Zhongzhuangpu in the south of the city, it came into contact with two divisions of Wu Qiwei's column that the enemy had rushed to aid Zunyi, and took advantage of the enemy's unstable foothold to launch an attack, and after repeated killings, most of the enemy troops were annihilated, and Wu Qiwei led the remnants to try to escape across the Wujiang River, except for a few personnel who followed him across the river and fled, the rest of the more than 1,800 people and a large number of weapons that had not yet crossed the river were all captured by the Red Army. The operation in the Zunyi area, which lasted five days, defeated and annihilated two enemy divisions and eight regiments, and captured more than 3,000 enemies.

That is to say, the first and second crossings in history, one loss and one win. After the end of the second crossing, Mao Weiren's position in the center was established. With military command, he took military command by surprise and commanded the third and fourth crossings of the Red Army.

Historically, after the Red Army won a great victory in Zunyi, Chiang Kai-shek hurriedly flew to Chongqing on March 2 and personally commanded the siege of the Red Army, attempting to adopt a combination of fortresses and key attacks, defending the south and attacking in the north, and encircling and annihilating the Red Army in the narrow area of Zunyi and Yaxi. In order to smash the enemy's new siege, Mao Weiren planned to wander around the Zunyi area in disguise to find the enemy, so as to lure the enemy to advance, and then transferred to the northwest to seek a new maneuver. At the same time, the Red 3rd Army Corps made a feint to Jinsha in the southwest direction, mobilized the enemy's Zhou Hunyuan division to the south and Wu Qiwei's division to the west, and then transferred troops to attack the Lubanchang defenders. When the enemy Wu Qiwei's troops crossed the Wujiang River in the north and the Yunnan army's Sun Du troops approached, on March 11, Mao Weiren led the army to suddenly turn to the north, and on the 15th, he entered Renhuai, crossed the Chishui River from Maotai for the third time on the 16th, and then entered southern Sichuan. The enemy mistakenly thought that the Red Army was about to cross the Yangtze River to the north again, so he hurriedly adjusted his deployment and pressed the Red Army to the south of Sichuan, in an attempt to form an encirclement of the Red Army again and gather and annihilate the Red Army on the south bank of the Yangtze River.

In order to further create the enemy's illusion and surprise, on March 21, Mao Weiren disguised the main force with the strength of one regiment and continued to advance in the direction of Gulin and Xuyong in southern Sichuan, leading the enemy to the west. The main force returned to the division and advanced eastward with rapid action, and on the 22nd, crossed the Chishui River for the fourth time and turned back to Guizhou again. On the 28th, the Red Army passed through the blockade line of enemy pillboxes between Yaxi and Fengxiangba and reached the north bank of the Wujiang River. On the night of the 29th, a platoon of the Red Army's vanguard regiment took advantage of the cover of a thunderstorm to reach the opposite bank on a bamboo raft and successfully captured the ferry, and by the 31st, except for the Red 9th Army Corps on the north bank of the Wujiang River, which continued to contain the enemy, the main force of the Red Army crossed the Wujiang River to the south and skillfully broke away from the enemy's encirclement. At this point, the "four crossings of Chishui" came to an end, and the Red Army finally completely got rid of the enemy's encirclement.

Unlike in history, at present, because of the arrival of Li Jiansheng, Mao Weiren has fully established his position at the Zunyi Conference and can directly command the actions of the Red Army. Similar to history, this time, the Central Red Army still launched the "Four Crossings of Chishui"; What is somewhat different from history is that this "Four Crossings of Chishui" was completely commanded by Mao Weiren.

Because of the containment of the enemy by Li Jiansheng's subordinates, the number of enemies who surrounded the Central Red Army was much smaller than in history, and they were somewhat forward-looking. This makes Mao Weiren's command even more like a fish in water. As soon as the first day of the first day of crossing the Chishui, the Central Red Army of the Central Army won a great victory: the Red First Army completely annihilated the Zhang Anping Brigade of the Sichuan Army and the Red Third Army Corps defeated the Dafenggang Brigade, although the Red Ninth Army Corps was also as in history, it was blocked by the Sichuan Army Task Force Xu Guoxuan's Department at Arrow Beach, but its strength was far stronger than in history, and it only fought with Xu for half a day to defeat the enemy. As a result, all three main forces crossed the river safely.

Is the great man Mao who has passed through Chishui easy to provoke? Along the way, I have been thinking about cutting off the enemy's fingers. As a result, Qinggangpo came into his sight. After discussing with several corps commanders, the three corps of the Red 1st, 3rd, and 9th Army Corps quickly assembled and semi-surrounded the Guo Xunqi Brigade of the Sichuan Army from three sides. Guo Xunqi's brigade is also a strong force, and when he saw that the situation was not good, he immediately stuck to wait for help, and called for support from the Panzuo brigade. This Pan Zuo Brigade was not far from the Guo Brigade, and after receiving the telegram asking for help, it immediately followed behind the Red Ninth Army and suddenly launched a fierce attack.

Pan Zuo's meaning is to want the two armies to attack inside and outside, and wipe out the main force of the red bandits!
