Green Standard Army
The Battle of Jiangnan (1860), also known as the Second rout of the Jiangnan Battalion () was a battle between the Qing government's Green Standard Army and the army of the Taiping Heavenly Kingdom during the Taiping Rebellion. The Green Standard Army twice attempted to besiege Nanjing, capital of the Taiping Heavenly Kingdom, but was unable to break through. To break the siege of Nanjing, the Taiping forces maneuvered to divert Qing forces by sacking Hangzhou, before quickly moving back to Nanjing to counter-encircle the Qing siege forces and routing the Green Standard Army garrison completely, breaking the siege of Nanjing.
