Huai Army
In September 1862 a Taiping army of 80,000 under the command of Tan Shaoguang mounted a second attack on Shanghai, which was defended by Maj. Gen. Guo Songlin (郭松林) of the Huai Army. The initial assault, led by Chen Bingwen (陳炳文), faltered when Cheng Xueqi destroyed all 20 Taiping camps (one of which accommodated 500 soldiers); Chen Binwen retreated to Sijiangkou (四江口), where he joined Tan Shaoguang.
