At nine o'clock on January 29, Shaozong received an official order from the Central Revolutionary Military Commission, demanding that Shaozong immediately seize the downstream ferry of the Chishui River in Tucheng. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

After receiving the order, Zhang Cheng immediately made arrangements, demanding that the whole army must abandon all unnecessary materials, including damaged mountain artillery and mortars, and ordered that the weight of each officer and soldier should not exceed 20 kilograms.

The 1st Division of the Young Communist Party and the engineer regiment directly under the column were the vanguard troops, and immediately seized the downstream ferry of the Chishui River in Tucheng, and after seizing the ferry, the engineer regiment immediately built a pontoon bridge.

Zhang Cheng led the troops directly under the column and the 2nd Division to defend the central column to cross the river, and the 3rd Division of the Young Communist Party was the rear of the whole army, demanding that the whole army must cross the Chishui River by 12 o'clock tomorrow noon.

After Li Yunlong and Lin Jianshe received the order, they immediately set off in full gear and galloped towards the downstream ferry of the Chishui River in a rapid marching manner.

When they arrived at the ferry, they found that there were no enemy guards on both sides of the Chishui River.

Li Yunlong and Lin Jianshe immediately ordered the troops to devote themselves to the work of building the bridge.

The engineer regiment immediately began to erect the pontoon bridge, and the 1st Division was responsible for the vigilance and sent various detachments to collect boats along the coast and prepare materials for the engineer regiment to build the bridge.

About an hour later, the search force collected more than a dozen large wooden boats, and the soldiers of the engineering regiment immediately placed the boats on the river, sank the large iron anchors to fix them, connected them with thick ropes and wooden poles, and then tied the boats firmly, and finally only laid wooden planks or door panels to build a pontoon bridge.

During the Long March, our army crossed the Xiaoshui, Xiangjiang and Wujiang rivers all the way, and it can be said that they are familiar with building bridges, and the water flow in the lower reaches of the Chishui River is far less turbulent than that of the Wujiang River, and the river surface is not very wide, so the speed of building bridges is very fast.

At 10 o'clock in the evening, a strong pontoon bridge capable of passing mule, horse, and mountain artillery crossed the surface of the Chishui River, and Li Yunlong immediately led the 1st Division and 1st Brigade to cross the river first, and set up a guard force on the south bank of the Chishui River, while the 6th Brigade stayed on the north bank to guard the pontoon bridge.

Half an hour later, Zhang Cheng led the 2nd Division to the ferry, and found that the pontoon bridge had been built and the 1st Division and 1st Brigade had crossed the Chishui River.

At about 11 o'clock in the evening, the central column also arrived at the ferry, Zhang Cheng and the political commissar hurriedly rushed forward, and then the central column began to cross the Chishui River, and by one o'clock in the morning of the next day, the whole army crossed the river smoothly.

Because the most powerful model division of the Sichuan army had just been wiped out by the Red Army, this achievement made the Sichuan army extremely frightened, and they did not dare to approach the Red Army easily, until the Red Army had crossed the Chishui River with all its troops, and the reconnaissance unit of the Sichuan army looked at the river and sighed, and watched the Red Army disappear into the vast night on the north bank of Chishui.

At the same time, the right column composed of the Red 1st and 9th Army Corps, under the leadership of Lin Nie and the two bosses, easily crossed the Chishui River at the Monkey Field Ferry.

The left column composed of the 3rd and 5th Red Army Corps, under the leadership of Mr. Peng, crossed the river from the upstream ferry of Tucheng.

Soon after crossing the river, Zhang Cheng again took the initiative to ask the commander-in-chief, and in accordance with the commander-in-chief's strategic intentions, the central column and the rest of the troops went straight to the Tashi area, and the 1st Division of the Young Column attacked the Xuyong and Gulin areas in southern Sichuan.

Zhang Cheng knew that in history, due to the tall and thick city walls of Xuyong County and the extremely strong garrison of the Sichuan army, the first army and the second division of the first army, which were originally responsible for capturing Xuyong, did not capture Xuyong City for three days due to the lack of heavy weapons, but instead lost troops and suffered heavy casualties.

Zhang Cheng naturally would not watch this tragic history repeat itself, so he took the initiative to suggest to the commander that the First Division of the Young Column should take on the heavy task of capturing Xuyong.

The commander-in-chief considered that the 1st Division of the Young Column had artillery units that the other units of the Red Army did not have, and that it was very beneficial to the siege of the city, so he decisively agreed to Zhang Cheng's active request for battle.

At half past three o'clock in the afternoon of January 31, Li Yunlong led the 1st Division and the artillery regiment directly under the column to Xuyong City, five miles away.

Xuyong is located at the southern edge of the Sichuan Basin, bordering Gulin County in the east, Bijie in Guizhou Province in the south, Xingwen in Yibin in the west, and Naxi in Luzhou in the north. It is connected to the northeast by the Yangtze River and Chishui in Guizhou Province, and by Xiongxian County and Weixin County in Yunnan Province in the southwest. It is the traffic artery connecting Guizhou Province and Yunnan Province, and it has always been a battleground for soldiers.

Xian Zhiyuan, the magistrate of Xuyong, was a reactionary element who was extremely opposed to the Workers' and Peasants' Party, and after hearing that the Red Army was coming to attack Xuyong, he built the city wall and fortifications day and night in the eastern city with strong men, and built eight pillboxes on the hills on the outskirts of the city.

On the one hand, more than 1,000 houses outside the city were forcibly demolished, and moats were dug along the foot of the city wall, and deer barriers were set up.

Considering that the area of Heiniwan, not far from the old east gate of Dongcheng, is low and gentle, and it is easy for the Red Army to attack, Xianzhiyuan determined this place to be a key defensive area.

He built the Black Mud Bay Bunker on a hill more than ten feet away from the city wall.

The bunker building is three-storey, the upper floor is higher than the city wall, and the view is wide. The pillbox had no door, only a firing muzzle.

There is a hidden ditch dug outside the bunker, which must be entered from the entrance of the dark hole in the inner wall of the old east gate, and can only enter the bunker through the tunnel.

Before the fortifications were completed, Xian Zhiyuan boasted that Xuyong City was impregnable, and the red bandits did not want to enter the county seat.

At this time, defending this place were five "volunteer brigades" composed of a regiment of the 1st Brigade of the Sichuan Army, two companies of the 2nd Brigade and the county militia regiment.

Just as the Sichuan army was stepping up the construction of fortifications and the Heiniwan bunker had not yet completed the roof, Xianzhiyuan received the news that "the Red Army had passed through the Sancha River and went straight to Xuyong County".

Xian Zhiyuan hurriedly agreed with Zhou Ruilin, commander of the 1st Brigade of the Sichuan Army: to defend Dongcheng with a battalion and the 1st Brigade of the Volunteer Brigade of the People's League, a battalion and the 2nd Brigade of the Volunteer Brigade of the People's Regiment to defend the Xicheng, and a battalion headquarters to be stationed between the upper and lower bridges for reinforcements.

After careful investigation by leading the reconnaissance company, Li Yunlong found that it was indeed difficult to break through Xuyong City, but with the help of the artillery regiment of the column, he decided to attack the city by force.

Li Yunlong then ordered his troops to feint on three sides to contain the defenders.

He personally led the main force of the 1st Division and Sun Youdao of the artillery regiment to hoard more than 100 cannons under the Nancheng Gate, and concentrated powerful firepower and troops to launch a general attack on the county seat.

At five o'clock in the afternoon, the battle officially began, and more than 100 mountain guns and mortars concentrated on the southern section of the city wall.

Only five minutes later, the southern city wall collapsed, and a large number of pillboxes, fortifications, and trenches outside the city were all razed to the ground by artillery fire.

Then the first division under the cover of artillery fire, the whole division sounded more than a dozen loud charges, the first division formed a commando team of 300 people, with a large number of automatic weapons to open the way, rapid attack, in one fell swoop from the collapsed city wall into Xuyong City, and then cover the follow-up troops into the city, a large number of troops suddenly rushed into the city like a tide.

After entering the city, the battle went very smoothly, and the enemy, under the attack of the Red Army's powerful firepower, was discouraged, and he was eager to let his father and mother have two more legs and began to flee for his life.

As the large troops of the first division continued to pour into the city, coupled with the encirclement on three sides, the enemy army completely became a turtle in the urn, Li Yunlong ordered the troops to shout "surrender the gun and not kill", and the enemy finally began to give up resistance and surrendered to the Red Army one after another.

An hour later, the fighting gradually subsided.

In order to avoid casualties among our troops, Li Yunlong immediately brought in eight mortars and only drove towards the government building, and Xian Zhiyuan finally surrendered in despair.
