Battle of Changsha (1944) - Aftermath

Aftermath

After 47 days of bitter fighting, Japanese troops managed to occupy Hengyang with a high price in casualties over the city of Hengyang - many lives were lost, including 390 Japanese commissioned officers dead and another 520 wounded. The 68th and 116th Divisions lost their combat strength and were reassigned to garrison duties. Thus, the Chinese troops to the north were able to expand their influence despite the loss of Hengyang city.

On the side of the Chinese National Revolutionary Army, Xue's Ninth Military Front in this campaign lost two effective corps loyal to Chiang Kai-Shek: the 4th and the 10th corps. This rendered "Tiger Xue" a toothless tiger until the end of the Second Sino-Japanese War.

Sequentially, the Japanese 11th Army moved toward Lingling, seizing it on 4 September 1944, and controlled Guilin on 10 November 1944. The Japanese China Expeditionary Army ostensibly had completed the strategic objective of the Imperial Japanese General Staff: linking up by occupation their territories in east Asia, (although they did not have enough manpower to maintain actual control over it due to their heavy losses).

Moreover, the United States Army Air Forces transferred all their bomber groups in the above Chinese air bases to newly captured Saipan in July 1944, during the battle of Hengyang. From Saipan, United States aerial fleets began their bombing campaign against the home islands of Japan. One of the Japanese tactical achievements in this bloody campaign, (Operation Ichi-Go), had been easily neutralized by a simple American military maneuver in the Pacific.

After the battle of Hengyang, the Japanese could not continue to fight effectively. During this period Japan discovered that government privileges from Wang Jingwei's puppet regime were useless, consequently they rejected plans to take more Chinese territory. At the same time their negotiating position with China became significantly less powerful—to the point where they agreed to set aside the "Tang Ju" treaty.

The Chinese government continued to pressure the Japanese to completely withdraw from the northeast. The Japanese, in a desperate measure, collected as many troops as possible in April 1945 to invade a heavy settlement (Zhijiang) in the west of Hunan, hoping to open a path to Sichuan. The troops were intercepted in an ambush by the Chinese National Guard and almost completely wiped out. China regained some of its territory. At this point, the course of the war had turned. The Japanese subsequently surrendered at the Zijiang River.
