What was the process of attacking Jingxing Coal Mine?

The battle of the central column attacking Jingxing coal mine was very beautiful.

After the Japanese army occupied Jingxing coal mine, it has always regarded the coal mine as an important garrison point. In order to plunder China's coal resources, the Japanese army built a wall nearly 4 meters high around the new and old mines, laid a power grid on the wall, added barbed wire outside the wall, and dug trenches. Within the fence, the Japanese army set up 22 forts in different corners of the new mine, the old mine and Beishan to monitor the whole mining area. Before the war, according to Commander Nie's instructions, the Central Column sent a small team to sneak into the mining area and got in touch with the coal miners. Under the cover of workers, the commanders of the 3 rd regiment cut off the power supply in the mining area and launched an attack in the dark.

120 division troops shelled enemy strongholds.
