In the Yimeng anti-sweeping campaign, the Japanese company was hit by the special service battalion of the 115th Division, and it gritted its teeth and was bound to put it to death and then quickly, on the 24th, more than 200 Japanese puppet troops in the old village stronghold directly attacked the north village where the special service battalion was stationed, and was immediately repelled. When the Japanese army heard the news, they were still not satisfied, and gathered more than 700 people overnight, and at dawn the next day, they once again invaded the North Village, and the two sides fought fiercely for one day, and the special service battalion repelled the enemy's three consecutive onslaughts. At dusk, after a company detoured to the enemy's side, the Eighth Route Army attacked on both sides, reportedly killing and wounding nearly three hundred enemy soldiers, and the remnants of the enemy were forced to retreat.
The Battle of Kitamura brought the prestige of the special service battalion, and since then, the Japanese army has remained in the stronghold, and a few people easily dare not leave the stronghold. According to this situation, Luo Ronghuan led some personnel of the organs to the mountain column to deploy the counter-"sweep" of the external troops.
The anti-"sweeping" on the inner line was extremely arduous and dangerous, and in addition to the strength of the Japanese army that remained in the stronghold, its main force was still repeatedly looking for a decisive battle for the Eighth Route Army. On November 29, 1941, the first branch of kang da was transferred to Daqingshan in the "Dongmengshan" area, and at this time, more than 5,000 people of the 10th Brigade of the Japanese Army were secretly entering the area around Daqingshan and arranging a closed circle.
The 10th Brigade was the main force of the Japanese army involved in the "Winter Sweep", and it was also coordinated by thousands of people from Liu Hei's seven puppet armies and local stubborn troops (referring to local puppet armies), with a total strength of more than 10,000 people. Due to the confusion of the small units of the Japanese army and other reasons, the Eighth Route Army did not find out in advance such a serious enemy situation.
On the morning of the 30th, the northeast mountain pass where the First Campus of the Kang University was stationed suddenly sounded with the sound of rapid gunfire. The First Branch of the Kang Da Was organized as the Tenth Detachment in the Shandong Eighth Route Army, and in the past it also undertook the task of cooperating with the fraternal units, and the cadets all heard that this was the kind of sound peculiar to the Japanese Army's 38th Dagai, from which it could be judged that it had encountered the main force of the Japanese army.
The situation was critical, and Zhou Chunquan, the principal of the First Branch of kang university, immediately ordered the whole school to urgently assemble to seize Daqingshan, and at the same time sent an urgent report to the main forces of the 115th Division and the Mountain Column: "There are a large number of devils here, we are surrounded, and we are organizing a breakthrough!" "The Japanese army touched it at dawn, and a squadron with a 92nd infantry gun seized the no. 1 height of Daqingshan and launched a rapid attack on the outpost of the branch school.
