The Third Battle of Nanjing in 1864 was the last major engagement of the Taiping Rebellion in the Qing Empire. With the fall of Nanjing, the capital of the Taiping Heavenly Kingdom, the rebellion came to an end. The Hunan Army, an unpaid and barely fed militia commissioned by the Qing Empire, lost all their discipline and committed mass-scale random murder, wartime rape, looting and arson against the civilians of Nanjing, seen as "rebels". 200,000–300,000 "rebels" were reported dead by Zeng Guofan, the commander-in-chief of the Hunan Army.
