Ussuri Cossack Host

Ussuri Cossack Host (Russian: Уссури́йское каза́чье во́йско) was a Cossack Host in Imperial Russia, located in Primorye south of Khabarovsk along the Ussuri River, the Sungari River, and around the Khanka Lake.

The Ussuri Cossack Host was created in 1889 on the basis of an unmounted half-battalion of the Amur Cossack Host and later reinforced with settlers from the Don Cossack Host, Kuban Cossack Host, and other Cossack hosts. The Ussuri Cossack Host headquarters was first located in Vladivostok and then in Iman (now Dalnerechensk). Its nakazny ataman (who was also the military governor of the region) subordinated to the Governor General of the Amur region, who, in turn, was the nakazny ataman of the Amur and the Ussuri Cossack Hosts.

The Ussuri Cossacks possessed 6740 km² of land. In 1916, they numbered 39,900 people in six stanitsas, which comprised 76 settlements. In times of peace, the Ussuri Cossacks supplied one cavalry battalion (300 men) and one platoon. The Ussuri Cossack Host was used for border patrol, postal and police service. It participated in the Russo-Japanese War. During the World War I, the Ussuri Cossacks supplied one cavalry regiment (600 men), one cavalry battalion, one platoon of guards, and six special sotnyas (total of 2,514 men). Most of the Ussuri Cossack Host took the side of the White movement during the Russian Civil War.
