October 1651 CE
Yerofey Khabarov sets off down the Amur after receiving reinforcements in June 1651.
His expedition had reached the mouth of the Sungari by September, and had by the 29th reached Achansk, near present-day Khabarovsk; they decide to winter here.
They are attacked on October 8 by a thousand local people, who, upon being defeated, appeal to their Manchu overlords.
