Please look at General Ding's description in the film: "The commander of the column, Ding Yaodong, followed the specific policy of" attacking the city for assistance and division of labor and cooperation ",analyzed the enemy's situation and made a battle plan. In the battle between Dongguang and Xijiao Airport, Ding Yaodong boldly used Wang's wrong judgment to subtly transfer the enemy's trump card, the 19th Army, and then took advantage of it to quickly capture Dongguang Mountain, which was easy to defend but difficult to attack. At the same time that our army took a strong military offensive against the enemy, our underground party closely cooperated with the siege troops to strengthen the political work against Wu, the commander of the airport garrison in the western suburbs of the enemy, and finally made him understand the situation and lead the uprising. "
This is the record of 9 vertical Nie Fengzhi. He attacked from the east and laid the Maoling Mountain for a long time, which made Wang think that the main attack direction was the eastern line, so he could only mobilize the reserves to the east, creating conditions for the attack to the west.
