顺治十八年，清廷为应对郑成功等反清势力的威胁，派祖永烈率汉军八旗进驻苏州，以加强江南地区的军事防御力量。苏州八旗驻防官兵人数约为数千人，驻营于苏州城北部。祖永烈所部军纪败坏，八旗军圈地占房，强行驱赶居民等行为，对当地社会经济造成较大的冲击与破坏。苏州八旗军的军费开支也成为沉重的财政负担。康熙三年，由于反清武装对江南的威胁减轻，清廷重新调整了军事部署，并将苏州八旗驻防裁撤。

In the 18th year of the Shunzhi-reign period ( 1661) ，in response to the threat of Zheng Chenggong and other anti- Qing forces，the Qing government ordered Zu Yonglie to lead the Hanjun Banners stationed in Suzhou，to strengthen the Jiangnan region's military defense forces． There were thousands of officers and soldiers in the Eight Banners Army in Suzhou and their barracks were in the north of the city． Zu Yonglie's troops were undisciplined and they occupied lands and homes，forced evictions of residents，and a destructive impact on the local society and economy． The military spending on the Eight Banners Army in Suzhou had also become a heavy financial burden． In the 3rd year of the Kangxi-reign period ( 1664 ) ，because the anti-Qing forces' threat to Jiangnan had been reduced，the Qing government re-adjusted its military deployment and abolished the Banner garrison in Suzhous.
