Don Cossack regiments of:

GL Nikolai Vasil'vich Ilovaiskii 5 (1772 (1769?)-1828);

GM Aleksei Vasil'evich Ilovaiskii 3 (1767-1842);

PK Andrei Ivanovich Bykhalov 1 (1757-1815); and

VS (Voiskovoi starshina - Cossack major) Vasilii Afanas'evich Kuteinikov 6 (1762-1823),

It should be noted that regiments were, at times, commanded by officers other than the 'regimental shef'. Ilovaiskii 3 is known to have been present.
