Geographically, Changsha is adjacent to Xiangjiang River in the west, high in the south and low in the north, especially in the east and north of Changsha city. Liuyang River and Laodao River are like a bag, with the mouth in the south and the bottom in the north. If the enemy can be driven to Liuyang River and Laodao River as the decisive battle sites, they can be gathered and annihilated. Of course, "Pocket Array" is the common name of citizens who have read many romance novels. In the third Changsha Battle, Xue Yue summarized the experience and lessons of the previous two battles and set up a more scientific "Heavenly Furnace Array".
Xue Yue himself said: "In order to form a deep-net-like stronghold position at the scheduled battle site, the soldiers of the Heavenly Furnace should deploy necessary garrison troops, and use ambush, luring the enemy, flank attack, interception, tail attack, blocking attack and other means to consume the enemy's strength one by one, and then use superior forces to counterattack and encircle the enemy at the decisive battle site, thus annihilating the enemy. Beggars' gangs are the way to retreat to the decisive battle. It is a new strategy to defeat the enemy because of the enemy's change, such as melting iron in the furnace and alchemy, hence the name. "
194 10+02 Before the third Changsha Battle broke out, Xue Yue had already worked out the tactics of the cupola, printed it into a manual and sent it to senior cadres, and arranged troops in advance. /kloc-in the middle of 0/2 years, the enemy invaded northern Hunan, and the enemy's front was directed at Changsha City, but it was like a controlled chess piece on the chessboard. Xue Yue said that he had "chosen the new wall and Miluoer water as ambush and bait areas. Diaoyu Island and Liuyang River are decisive battle zones. During the war, people stepped up the work of farming, storing water and building roads. " Therefore, when the Japanese invaders invaded northern Hunan and Changsha for the third time, Xue Yue asked the Tenth Army guarding Changsha to hold the Japanese army tightly like a magnet, and at the same time, reinforcements from all walks of life marched in and surrounded the Japanese army with superior forces.
