In early September 1932, as Chiang Kai-shek's 500,000 troops attacked the Eyu-Anhui Soviet Region, the main force of the Red Fourth Front retreated to the Jinjiazhai area, joined the Red 25th Army, and divided the 74th Division of the Red 25th Army into the main divisions.
This was the only all-army division of the Red Fourth Front.
However, because of the defeat of the anti-"encirclement and suppression" campaign, the Kuomintang army Wei Lihuang led his troops to occupy Jinjiazhai.
In late September, when the enemy was more than 100,000 and chased after them, the Eyu-Anhui Central Sub-Bureau adopted the advice of Cai Shenxi, commander of the Red 25th Army, abandoned the plan to dive out of the east and moved towards Pinghan Road.
The Five Star County Independent Regiment was responsible for cover.
They defeated the tail-chasing enemy at the Mao River.
Under the cover of the Independent Regiment, the main force of the Red Fourth Front successfully broke through.
On October 8, the Red 10th Division and Hu Zongnan's 1st Division encountered each other at the mouth of the Huang'an River. The Red Army immediately attacked the enemy bravely and fought fiercely for several hours. Due to the arrival of 1 brigade of the 88th Division of the enemy reinforcement Qian Dajun, the Red 25th Army covered the transfer of the main force, and Commander Cai Shenxi personally commanded the battle, unfortunately, he was seriously wounded in the battle, and still sat on a stretcher to direct the battle. Finally, the Red Army finally defeated the enemy soldiers.
However, Commander Cai Shenxi was unfortunately killed.
In the Battle of Estuary, the Red 29th Regiment captured for the first time more than 30 enemy automatic rifles.
After the war, the Red Fourth Front withdrew to Huang chaiba north of the estuary.
Hong Xuezhi, commander of the machine gun company of the Red 29th Regiment, was ordered to lead the unit to guard the headquarters of the Red 10th Division.
One day, the political commissar of the Red 10th Division, Gan Jishi, came to the Red 29th Regiment. He happily came to a large courtyard to check the spoils of the last battle.
Many captured guns were concentrated in the compound.
The guard platoon did not pay attention, and there were bullets in the guns. Unexpectedly, a prisoner took advantage of everyone's lack of attention, picked up a gun from the ground, pulled the trigger, "snapped", and a shot hit the political commissar of Ganjishi in the abdomen.
The political commissar of the Red 10th Division was thus sacrificed.
In the Battle of Hekou, the Red Fourth Front killed two division-level generals, one was Cai Shenxi, the commander of the Red 25th Army, and the other was Gan Jishi, the political commissar of the Red 10th Division. Hong Xuezhi lamented the battle decades later, saying: "Commander Cai is very talented, and he was only 28 years old when he died. Commissar Gan's sacrifice was too undeserved, and if he were alive, he should also be a general. ”
