In 1707, Apostol Kigetsch, a Wallachian nobleman-serving Emperor Peter the Great, was commanded to form a "khorugv" ("banner" or "squadron") of 300 men to serve on the Ottoman-Russian border. The squadron consisted of Christians from Hungary, Serbia, Moldova and Wallachia. In 1711, prior to the Pruth campaign, 6 regiments (4 khorugv's each) of hussars were subsequently formed, mainly from Wallachia. Two other 'khorugv', for guerilla warfare, were formed, one Polish and one Serbian, to serve against the Ottomans.
