(TV series "Nie Rongzhen")
After the Hundred Regiments War, the Japanese North China Front believed that one of the lessons was that the intelligence collection of the Eighth Route Army was insufficient, so they adjusted and strengthened it, including monitoring and deciphering the telegram code of the Eighth Route Army. Since the Jin-Cha-Ji organs were targeted by the Japanese army, Nie Rongzhen, commander of the Jin-Cha-Ji Military Region, discovered that the enemy had been tracking and listening to the radio stations of the Military Region, and the reason why the organs had fallen back into the circle of combined strikes that day was because the enemy had already found their position in Leibao through the radio position of the Military Region.
Nie Rongzhen decided to continue the transfer after dusk, and at the same time, he ordered all the radio stations of the military region to temporarily stop contacting the outside world, and left a reconnaissance detachment and a radio station behind, disguised as the military region radio, and still using the call sign of the military region to constantly communicate with all sides.
After drilling through the gaps in the enemy's combined strike circle, the mechanism was hidden in a new location for several days. After the use of radio stations ceased, Nie Rongzhen and other military region chiefs only used secret telephone lines to direct "counter-sweeping" through secret telephone lines; in addition, there were no fireworks or fireworks during the day and no traces were revealed, so the enemy could not detect their location at all.
The Jin-Cha-Ji organs had close to 10,000 personnel and many heavy horses, but the enemy did not know that this huge marching contingent had broken out of the circle of combined attack, and one of the reasons was that the reconnaissance detachment had led the enemy past by constantly sending out reports. The reconnaissance detachment had only more than fifty people, and the target was small, so it was easy to break through. In order to confuse the enemy, in addition to setting up radio stations and "communicating" with all sides during the transfer process, they also deliberately used many different unit numbers to post road signs and houses along the way, and even sometimes threw away a few insignificant pieces of waste paper, so as to better prove to the enemy that they were "Nie Headquarters" radio stations.
Of course, this was only temporary; at that time, the radio stations of the CPC Central Committee, the headquarters of the Eighth Route Army, and the military sub-districts were calling all the time, and the radio stations of the Jinchayi Military Region could not always fail to answer. On September 7, after completely breaking away from the enemy's encirclement and moving to the outer line, the Jin-Cha-Ji organs continued to use radio stations to communicate normally with all parties.
(TV series "Eastern Battlefield", Five Heroes of Wolf's Tooth Mountain)
In late September, the Japanese puppet army encircled the eastern gateway of the Jin-Cha-Ji base area, Wolf's Tooth Mountain, which broke out into the Battle of Wolf's Tooth Mountain, and the famous "Five Heroes of Wolf's Tooth Mountain" emerged. At this time, the enemy's autumn "sweep" was basically over, and in this "great sweep", the Japanese army failed to attack Jizhong as much as it did
In the sense that the Tenth Division inflicted heavy losses on the main forces of the Eighth Route Army,
The "Great Sweep" was a failure, even
Okamura also had to admit that "the elimination of the Eighth Route Army will not work in the short term."
Jin-Cha-Ji is an old base area and is also recognized as a model base area behind enemy lines, where the Eighth Route Army can fight without a map, the troops will not lose their way even in the night of the storm, when fighting, the wounded and sick can be treated in time, and supplies, ammunition, and medicine can be supplied everywhere. Not only that, the guerrillas and militias in Jin-Cha-Ji were also extremely active; during the anti-"mopping-up, the militia organizations continued to kill and injure the enemy through "sparrow warfare" and other means, and the Japanese army was amazed by it, believing that the militia in the Jin-Cha-Ji Border Region even had the same significance as the Eighth Route Army.
Nevertheless, the situation facing Jin-Cha-Ji is still extremely grim. After the end of the "Autumn Sweep," the Japanese army immediately adopted a new policy of "encroachment" on the Jin-Cha-Ji base area, and they approached the base area step by step by repairing the bunkers of the artillery towers, digging blockade ditches, and building blockade walls. Under the enemy's "encroachment" and blockade, beiyue district suddenly lost more than a thousand villages, several counties belonging to the third sub-district were occupied by the enemy for seventy percent, and all the troops and sub-district organs were forced to retreat to the southern mountains of Fuping and Taihang Mountains.
In the base areas, the fields were deserted, the people had no means of subsistence, and the supply of troops was extremely difficult, and sometimes even wild vegetable leaves could only be used to fill the hunger, and Jin-Cha-Ji entered the most arduous period of the War of Resistance.
