In 1937, during the Songhu War of Resistance, when the 20th Army of the Sichuan Army arrived in Shanghai, just when the Japanese army was carrying out the so-called "third reinforcement, fourth general offensive", the whole army immediately entered the position and defended the Japanese army in the area of Yunzaobin, Qiaotingzhai and Chen Jiaxing.
In the fiercest battle, the 20th Army held its position to the death, preferring to die rather than retreat.
On the fifth day of the fierce battle between China and Japan, in the afternoon, the Position of Chen Jiaxing, which was in charge of the Central Army, was broken by the Japanese army. Xue Yue, commander-in-chief of the 19th Army, ordered the Sichuan army to counterattack. Janssen ordered the 133rd Division to advance rapidly and carry out its mission.
As soon as the Sichuan army went up, they saw the remnants of the Central Army running away and running around, but they continued to move forward desperately, and after crossing the remnants of the Central Army, the vanguard troops immediately changed into scattered formations and fired fiercely at the pursuing Japanese troops with machine guns and rifles.
The Japanese army thought it was victorious and was pursuing the remnants of the Central Army, but suddenly so many Chinese soldiers appeared, so they stagnated. A standoff between the two sides. Then, the Sichuan army launched a charge, charging all over the line and engaging in hand-to-hand combat with the Japanese army. Casualties on both sides were heavy. However, the Sichuan army is a fresh force, the former servants followed, more and more people went up, the Japanese aircraft artillery could not play a role, after an hour of fighting, the Japanese army finally did not support, and fled backwards. The Sichuan army completely recovered the lost positions of the Central Army and captured a lot of guns and ammunition from the Japanese army.
Subsequently, the 133rd Division fought fiercely with the enemy for three consecutive days.
Every day after dawn, the Japanese sent aircraft to take turns bombing, artillery cover, and then infantry launched a continuous attack. The Sichuan army stubbornly resisted and suffered heavy casualties. Often, the follow-up troops supported by enemy aircraft can only lurk in the cotton field, wait for the Japanese aircraft to turn around and leave, then leap forward a section, and creep forward.
On the battlefield, officers and men can only eat one meal a day before dawn and at nightfall.
However, their morale is still strong, and their positions are standing still.
On the morning of the third day, the situation in the Position of Yunzaobang defended by Li Jieli's regiment was critical, and there was only one battalion left in the reserve Xu Zhaolin Regiment. There were only a few soldiers left in the Chen Jiaxing position. Division commander Yang Hanyu had no troops to send, so he had to send his own guard unit, the pistol company of the division headquarters.
In the afternoon, Xue Yue ordered that the 21st Army of Liao Lei in Guangxi take over the defense line of the 20th Army. Soon, the 48th Army of Wei Yunsong came to take over the positions of yunzaobang and Chen Jiaxing of the 397th Brigade.
At the time of the handover, the Japanese army attacked the position of Yunzaohama again. As soon as the Gui's receiving troops entered the position, they were not stable on their feet, and they retreated backwards. The 397th Brigade of the Sichuan Army immediately ordered Li Jieli's regiment to continue to resist and wait until the Gui army's position was completely secured before retreating.
Li Jieli immediately commanded a battalion to fight back bravely, repelling the Japanese. However, his own casualties were even greater, and Li Jieli was also wounded in the hand, and had to insist on commanding the battle.
It was not until dusk that the two armies were finished fighting,
After nightfall, Li Jieli retreated with the brigade headquarters to Lijia Village and was sent to Suzhou Hospital for treatment. After the war, he was promoted to major general.
In the seven-day and seven-night battle, the 20th Army of the Sichuan Army suffered unprecedented casualties, with 280 cadres above the platoon commander and above and more than 7,000 soldiers. In particular, the 397th Brigade had only 40 soldiers left.
