In mid-May 1935, Chiang Kai-shek mobilized more than 30 regiments to "encircle and suppress" the Red 25th Army. The Eyu-Anhui Provincial CPC Committee held a meeting on anti-"encirclement and suppression" operations, and commander Xu Haidong put forward the operational policy of "first tired and then fighting," that is, taking advantage of the new arrival of the Northeast Army, our army first went north, tried to eat one of its parts, and then dragged the enemy for a long time, and once it caught a favorable fighter, we would strive to annihilate one or two of its divisions (brigades).
This proposal was agreed by the provincial party committee.
Subsequently, the Red Army set out from the Second Heavenly Gate in Yunxi, and the procession first went north, then to the east, and then to the south, dragging the enemy away. Seventy miles today, eighty miles tomorrow, walking every day, night and night. On the night of June 15, Xu Haidong personally commanded the pistol regiment, ran 130 miles a day, pretended to be the enemy's 44th Division, and captured Jingziguan, a key area on the border of Hubei and Shaanxi, in one fell swoop, and completely annihilated more than 200 enemy defenders.
This place was the supply depot of the enemy's 44th Division, and the Red Army captured a lot of military supplies, and one by one they smiled.
In fact, annihilating 200 enemy personnel was not Xu Haidong's goal.
It was one of his enticing plans.
Xu Haidong took Bauhinia Pass in order to attract the enemy over.
When the others were worried that the enemy would not take the bait, information suddenly came: the three divisions of the enemy's 67th Army, the 44th Division, the 1st Police Brigade, and other units immediately came to Jingziguan as if they had stabbed a honeycomb.
Therefore, the Red 25th Army began to move according to Xu Haidong's predetermined route. The procession continued westward along the lofty mountains. Stop-and-go. On 25 June, the troops were transferred back to the Shanyang Xiaohekou area. That night, Xu Haidong held a meeting of cadres at and above the regimental level and said: "Don't leave, wait and see, whichever way the enemy comes up first, he will eat it." ”
As a result, they waited for four days, looked at the terrain, rested their troops, and the 1st Enemy Garrison Brigade chased after them.
The enemy's combat effectiveness of this brigade was not too strong, but because it had not suffered the defeat of the Red Army, it began to be very arrogant. Brigade Commander Tang Sitong came out of the Whampoa Military Academy, bent on grabbing a head, full of energy, so he ran to the front.
At dawn on July 2, the Red Army suddenly launched an attack on the 1st Police Brigade at the mouth of Yuanjiagou, and after only more than eight hours of fighting, more than 1,800 people of the 1st Police Brigade were all annihilated.
As soon as the battle was over, Xu Haidong personally took a platoon of pistols to find the "big official" from the prisoners. The enemy brigade commander Tang Sitong was full of beards, but at this moment, he changed into a gray cloth military uniform on his upper body and only a pair of yellow cloth shorts on his lower body, which was worse than ordinary soldiers, like an old man, and was immediately found out and trembled when he was escorted to Xu Haidong.
Xu Haidong saw him like this, smiled and said, "Brigadier Tang, you have worked hard these days!" ”
"The Red Army is hard, the Red Army is hard..." Tang Sitong did not know how to answer, nor did he know that the person in front of him was Xu Haidong. When Xu Haidong asked him some more military information, he was stubborn and refused to answer.
Xu Haidong was on fire, and after a few reprimands, he said: "Not honest, not convinced, without your good fruit to eat!" Bet on!"
Tang Sitong was a little flustered, and said in a loud voice, "Please send me to see your General Xu!"
Xu Haidong didn't hear clearly, twisted his face back and asked, "Who do you want to see?"
"See, see... General Xu Haidong. ”
Xu Haidong personally interrogated many prisoners, but for the first time he heard him called "general", he smiled bitterly and said, "You can't see him, you have already eliminated him." Saying that, he took out a Kuomintang leaflet from his pocket, shook it to Tang Sitong a few times, and said: "Your piece of paper is printed, the leaders of the Red Army are dead, and the Red Army is already a group of leadersless rabble- ”
The 1st Police Brigade was completely annihilated, and Tang Sitong was captured, which shook southern Shaanxi and shocked the Northeast Army and the Northwest Army. At this time, the 110th Division of the enemy's Northeast Army was only 40 miles away from the Red Army, and despite shangfeng's death orders, it did not dare to advance. At this point, the enemy's second "encirclement and suppression" was bankrupt.
