In August 1942, the Chief of the OKH, Colonel-General F. Halder signed instruction No. 8000/42 concerning "The use of local auxiliary forces in the East." In it, all volunteer formations were categorized by their political loyalty and battle-worthiness. It read: "Cossacks and peoples of the Turkish race, fighting against the Bolshevik enemy arm in arm with German soldiers, stand out as fullfledged brothers-in-arms. Here also are included: Turkish battalions, Cossack sub-units, Crimean Tatars..."
The exact origins of Cossacks remain unclear. In the modern view, Don Cossacks descend from Slavic people connected with Russian lands like the Povolzhye, the Dnieper, the Novgorod Republic, and the Principality of Ryazan.
