The battle of Yinji (尹集战斗) was fought at the Yin Village (Yinji, 尹集) of Wuyang (舞阳) County in southern Henan, and it was a clash between the communists and the former nationalists turned Japanese puppet regime force who rejoined the nationalists after World War II. The battle was one of the Chinese Civil War in the immediate post World War II era, and resulted in communist victory.
Like other similar clashes immediately after the end of World War II between the communists and the nationalists in China, this conflict also rooted from the fact that Chiang Kai-shek had realized that his nationalist regime simply had neither the sufficient troops nor enough transportation assets to deploy his troops into the Japanese-occupied regions of China. Unwilling to let the communists who had already dominated most of the rural regions in China to further expand their territories by accepting the Japanese surrender and thus would consequently control the Japanese occupied regions, Chiang Kai-shek ordered the Japanese and their turncoat Chinese puppet regime not to surrender to the communists and kept their fighting capabilities to “maintain order” in the Japanese occupied regions, fighting off the communists as necessary, until the final arrivals and completion of the deployment of the nationalist troops. As a result, most members of the Japanese puppet regimes and their military forces rejoined the nationalists.
However, most of these former nationalists turned Japanese puppet regime forces were not from Chiang Kai-shek's own clique, but instead, they were mainly consisted of troops of warlords who were only nominally under the Chiang Kai-shek's before World War II, since they were nationalists in name only and mostly maintained their independent and semi-independent status. These warlords were only interested in keeping their own power and defected to the Japanese side when Japanese invaders offered to let them keep their power in exchange for their collaborations. After World War II, these forces of former Japanese puppet regimes once again returned to the nationalist camp for the same reason they defected to the Japanese invaders. Obviously, it was difficult for Chiang to immediately get rid of these warlords for good as soon as they surrendered to Chiang and rejoined nationalists, because such move would alienate other factions within the nationalist ranks, and these former Japanese puppet regime's warlords could still help the nationalists to gain more territories by holding on to what was under their control until Chiang completed the deployment of his own troops to take over. Chiang Kai-shek's objective was to simultaneously solve the warlord problem that had plagued China for so long and the problem of the extermination of communism together, which proved to be an extremely fatal mistake for him and his nationalist regime later on, as shown in this conflict.
In accordance with his strategy to simultaneously solve the warlord problem that had plagued China for so long and the problem of the extermination of communism together, Chiang Kai-shek and his followers had hoped that these former Japanese puppet regime's warlords who rejoined the nationalists would be able to hold on to the regions long enough for Chiang to deploy his own troops by holding off communists. If the communists were victorious in such conflicts, however, the result would still benefit to Chiang and China because the power of these warlords would be reduced as their military forces were smashed by the communists, and the warlord problem plagued China for so long could thus be greatly reduced, while at the same time, communists would be weakened by the fights and Chiang's own troops would have easier time to take control.
For the former nationalist turned Japanese puppet regime forces, these warlords and their troops had no problem of following Chiang Kai-shek's orders, and they were eager to prove themselves. These warlords and their troops were well aware that due to the collaboration with the Japanese invaders during the Second Sino-Japanese War, they were well hated by the general population in China, including those nationalists who refused to surrender to the enemy and fought the enemy until the eventual victory. Therefore, in the impending demilitarization after World War II, they would certainly be disarmed and discharged, which would probably be the best outcome and the power of these warlord would be reduced or even completely eliminated as a result. Chiang Kai-shek's ordering them not surrendering to the communists and fighting off the communists was a savior for them because by carrying out such orders, these warlords and their troops could legitimize themselves and thus retain their power by fighting the communists who were targeted as rebels by Chiang Kai-shek and his nationalist regime.
The communist strategy was much simpler than that of the nationalists because there was not any huge division within the communist rank like that of the nationalist. The communists already earned considerable popular support by being the only Chinese force left in the region fighting the Japanese invaders and their puppet regime after the nationalist withdrew, and after successfully establishing communist bases in the rural regions where better life was provided to the general populace in comparison to that of Japanese occupied regions, the general Chinese populace agreed that the communists were well deserved to represent the China to accept the invaders’ surrender in the region and takeover the regions occupied by the invaders.
On August 26, 1945, the 13th Brigade of the 5th Division of the communist New Fourth Army decided to take Yin Village (Yinji, 尹集) of Wuyang (舞阳) County in southern Henan by force after the local defenders consisted of former nationalists turned Japanese puppet regime force who rejoined the nationalists after World War II refused to surrender. The 38th Regiment, 2 battalions of 39th Regiment, and 4 companies of the 4th Marching-on Regiment of the 13th Brigade of the 5th Division of the communist New Fourth Army attacked the village from both the east and the west. The communist 38th Regiment first annihilated a regiment of defenders at the outskirt of the village while at night, the two battalions of the communist 39th Regiment annihilated another regiment of defenders at Cypress Village Camp (Baizhuangzhai, 柏庄寨). After losing two regiments and all of strongholds outside the village, the remaining defenders lost the will to fight and escaped to Wuyang (舞阳) on August 27, 1945. The communists managed to capture more than 800 defenders alive and over 300 guns in their victory.
Like other similar clashes immediately after the end of World War II between the communists and the nationalists in China, this conflict also showed that Chiang Kai-shek's attempt to simultaneously solve the warlord problem that had plagued China for so long and the problem of the extermination of communism together proved to be a fatal mistake. Although the result of the campaign turned out exactly like Chiang Kai-shek and his subordinates had predicted, and consequently the power of the warlords in this region was indeed reduced as their military forces were smashed by the communists, so that the warlord problem plagued China for so long was thus reduced for this particular region, and Chiang Kai-shek's secondary objective was achieved here, any positive gains obtained by the nationalists were negated by the politic fallout. The reason was that this success of achieving the secondary objective came at a huge cost in nationalists’ loss of popular support in this region formerly dominated by the Japanese, because the local population had already blamed nationalists for losing the regions to the Japanese invaders, while reassigning these former Japanese puppet regime forces as the nationalist forces to fight the communists, the only Chinese force left in the regions, only further alienated the local populace and strengthened the popular resentment to Chiang Kai-shek and his nationalist government.
