The friendship between the Kazakh and Russian peoples was undoubtedly evident in their joint war against Napoleon's army.
The Kazakhs provided the troops with provisions, cheap, high-quality meat, carts, and horses. Specifically, between 1804 and 1815, approximately 50,000 horses were purchased from the Kazakhs of the Bukey Horde.
According to official history, at least 5,000 Kazakh warriors participated in the Battle of Borodino. According to these sources, since steppe dwellers did not have compulsory military service, all Kazakhs who participated in this battle were volunteers. Among the so-called volunteers who swelled the ranks of the Russian army were those Kazakhs who lived in Siberia and the Urals or who neighbored the Ural and Siberian Cossack hosts. Among them were Kazakhs who had served in the Cossack armies and converted to Christianity.
