Southern Jiangsu Campaign (Chinese: 苏南战役) was a 1945 series battle fought at the Southern Jiangsu and adjacent regions in Anhui and northern Zhejiang, 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 with their Japanese ally. The battle was one of the Chinese Civil War in the immediate post World War II era, and resulted in communist victory.
Prelude
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 former Japanese-occupied regions of China. Unwilling to let the communists who had already dominated most of the rural regions in occupied China to further expand their territories by accepting the Japanese surrender and thus would consequently control other 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 administration 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 and allegiance. 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.
Nationalist Strategy
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 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.
Communist Strategy
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.

Campaign
On September 8, 1945, the 1st Column of the communist Jiangsu – Zhejiang Military Region decided to take controls of regions in central Jiangsu, northern Zhejiang and adjacent regions in Anhui by force after the local defenders consisted of Japanese troops and former nationalists turned Japanese puppet regime force who rejoined the nationalists after World War II refused to surrender. Since mid August, 1945, over a dozen enemy strongholds in the region from Jurong (句容) County in Jiangsu in the north to Changxing (长兴) County in Zhejiang in the south had fallen into the communist hands, including those at Front Horse (Qianma, 前马), Southern Crossing (Nandu, 南渡), Celestial King Temple (Tianwangsi, 天王寺), Baonian (宝埝) and Jiapu (夹铺 on Taihu Lake in Changxing County) regions.
On August 14, 1945, the 8th Regiment of the 3rd Division of the former nationalists turned Japanese puppet regime force totaling over 1,200 ventured out Jurong (句容) in an attempt to counterattack, and they were assisted by two companies of Japanese troops. The 1st Regiment of the 1st Column of the communist Jiangsu – Zhejiang Military Region ambushed the enemy at Zhang Family's Hills (Zhangjiagang, 张家岗), and Duan Family's Bridge (Duanjiaqiao, 段家桥) regions, and after an eleven-hour long fight, succeeded in killing over 30 Japanese troops and over 370 nationalist troops, including the regimental commander of the nationalist 8th Regiment of the 3rd Division. One Japanese troops and over 350 nationalist troops were also captured alive by the communist troops.
On August 19, 1945, the 1st Column of the communist Jiangsu – Zhejiang Military Region attacked Jintan and Liyang, and annihilated the defenders consisted of a detachment of Japanese troops and two regiments of former nationalists turned Japanese puppet regime force in the process. Over 1,700 nationalist troops were captured alive by the attacking communists. Four artillery pieces and 48 machine guns also fell into communist hands. Taking advantage of their gains, communists took towns of Lishui (溧水), Gaochun (高淳), and towns of Eastern Hill, River Ripe (Hushu, 湖熟) of Jiangning (江宁) County, threatened the suburb of Nanjing. On August 24, 1945, Ji'an fell into communist hands, and on August 25, 1945, Langxi County fell into the communist hands. The campaign finally concluded on August 28, 1945, when Guangde County fell into communist hands.
Outcome
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 and Wang Jingwei regime, 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.
