The Third Battle of Changsha (known on the Japanese side as the Second Battle of Changsha), which took place from late December 1941 to mid-January 1942, was the first victory on the Allied side since the outbreak of the Pacific War. As far as the Chinese theater is concerned, this battle was one of the larger battle-level victories on the Nationalist side during the strategic holding phase marked by the end of the Battle of Wuhan. Not even the biggest victory of the strategic counter-offensive phase from March to May 1945: the Battle of Xiangxi (also known as the Battle of Xuefengshan, and by the Japanese side as the Zhijiang and Laohuokou Campaigns) can be compared to it.

Because Li Yutang and other generals commanded the Tenth Army to successfully defend Changsha, after the battle, Li Yutang, the army commander who had been "left in charge," was promoted to deputy commander of the 27th Group Army, Fang Xianjue, the former commander of the 10th Division, was promoted to commander of the 10th Army, and Ge Xiancai, the former commander of the 28th Regiment, was promoted to deputy commander of the 10th Division, while other generals who had received battle honors were also rewarded with awards and awards. Other generals who gained battle honors were also rewarded by the National Army Command. Although the Chinese side won the battle, but also concluded that in the late interception of the Japanese operation, the Chinese army neglected to focus on the control of the river crossing point and was not able to forcefully destroy the Japanese crossing equipment so that the Japanese army did not suffer a large establishment of annihilating blow; the Japanese side that the battle was not well-prepared, in the process of changing the order of the command was inappropriate, so that the operation was trapped in a passive.

After the Third Battle of Changsha, a large-scale celebration was held in China's Ninth Theater. Shortly after the end of the battle, the United States announced a loan of 500 million U.S. dollars to China, and the Allied Powers decided to appoint Chiang Chung-cheng as the supreme commander of the Allied Forces in the China-India-Burma Theater. In the following month, Chiang Chung-cheng visited India and lobbied for India to join the Allied Forces, and because of the influence of the victory of China in the battle, India finally agreed to join the Allied Powers. Subsequently, the United States and Britain announced the abolition of the unequal treaties with China. In the following two years, the Japanese army did not launch any large-scale attack on the Ninth Theater. However, the troops of the Ninth Theater, especially the first-line garrison of Changsha, relaxed their vigilance due to the long-term hold, and the Japanese summed up the lessons learned after the battle, so in the Battle of Changsha and Hengshan in 1944, the Japanese army, after full preparation, concentrated its main force of more than 200,000 men to launch an offensive to the Ninth Theater and changed its strategy of advancing, instead of going up against the water of the Xiangjiang River to capture the Yuelushan artillery position first, and the Japanese army succeeded in capturing Changsha in the Fourth Battle of Changsha in 1944. In the Fourth Battle of Changsha in 1944, the Japanese army successfully captured Changsha, and in the entire Battle of Changheng, the Ninth District was crushed and no longer had the ability to counterattack until the end of the war. Only in the Battle of Hengyang, the Tenth Army held Hengyang alone for 47 days and dealt a heavy blow to the Japanese army, which greatly slowed down the process of the Japanese army's plan to open up its "land lines of communication", and made Japan's domestic production of raw materials in short supply, thus creating strategic advantages for the Chinese army to meet the Allied counterattacks in the west of Yunnan and north of Burma as well as the U.S. army's counterattacks in the Pacific Theater. The first is to make a new one, and the second is to make a new one.
