Origin and History
After the Bulavin Uprising (1707-09), the land along the Khopyor River was taken away from the Don Cossack Host and repopulated by amnestied Don Cossacks and partly by Slobodian Cossacks who formed the Khopyor Cossack command.

|Illustrations of Cossacks
|The Anne S. K. Brown Military Collection at Brown University make available a large number of illustrations depicting Cossacks. Even though they are mostly of the 1812-1815 period, they give a fairly good idea of the way Cossacks dressed during this era.
At the outbreak of the Seven Years' War, these Cossacks did not wear uniforms. The following description is very conjectural and based on the clothing of other Cossack units.
Caftans and waistcoats were often made of blue cloth. Their hair was cut in roundel. They wore a high bonnet of sheepskin. Coats of rank and file were girdled with an ordinary sabre strap or a belt of coarse fabric material. Leaders wore silken belt from Persia or Poland over the sabre belt. Sabre was worn over the waistcoat. Some cossacks, especially the rank and file had only a mustache, beard was less common. They wore woollen trousers, half boots of black Morocco leather or simple leather. The Cossacks trousers were similar to the Turkish ones, but much tighter.
Troopers were usually armed with a lance, a sabre and a pistol. They could also carry a knife and a musket.
