Essay from the inaccessible edition of the Note of the Russian Scientific Institute. No. 9. Belgrade, 1933The task of this work is to find out and view in chronological order, the first combat clashes, the first mutual meetings on the battlefield, the first, so to speak, "military acquaintance" between two great peoples: the Russians and the Turks by the Ottomans ("Turk-Ottomans") - two historical rivals, whose struggle was then full of subsequent centuries. This struggle cost both the Russian and Turkish peoples innumerable victims. She broke the power and great power of the Ottoman Empire. The Russian people, however, were not destined, at least in our time, to bring this struggle to the cherished dream that his best sons cherished for centuries.
