The Battle of Changde (Battle of Changteh; ) was a major engagement in the Second Sino-Japanese War in and around the Chinese city of Changde (Changteh) in the province of Hunan. During the battle, the Imperial Japanese Army extensively used chemical weapons. The purpose of the Japanese offensive was not to hold the city but to maintain pressure on the Chinese National Revolutionary Army to reduce its combat ability in the region and its ability to reinforce the Burma Campaign. The Japanese were initially successful in their offensive operation by bacteria-infected bombs and captured parts of the city of Changde, which forced civilians to evacuate. However, the Japanese were pinned down in the city by a single Chinese division long enough for other Chinese units to surround them with a counterencirclement. Heavy casualties and the loss of their supply lines then forced the Japanese to withdraw, which returned territorial control to the original status quo. Some contemporary Western newspapers depicted the battle as a Chinese victory. American government film footage showed victorious Chinese troops with Japanese prisoners and captured Japanese flags and equipment on display after the battle. In addition, an American newsreel titled Chinese troops drive Japs from Changteh showed Chinese troops firing, with dead and captured Japanese on display. A British newsreel titled Japs Loose Changteh Aka Japs Lose Changte showed similar footage.
