摘要:The article examines the losses of the Caucasian troops of the Russian army during the Russian-Turkish and Russian-Persian wars in the 19th century. The attention is paid to the chronology of events, the active periods of hostilities, as well as to the identification of the average daily losses of the Russian army in the Caucasian theater of operations.As a source, the authors used the “The collection of information on the losses of the Caucasian troops during the wars of the Caucasus-Gory, Persian, Turkish and in the Trans-Caspian region”, which was published in Tiflis in 1901. It was prepared by employees of the military-historical department of the headquarters of the Caucasian Military District, its compiler was A.L. Gisetti. The materials presented in the collection cover the period of the Caucasian War of 1801−1864, the Russian-Persian and Russian-Turkish wars in the XIX century, as well as the campaigns of the Russian army in Central Asia.Methodologically, the work is based on the principles of historicism and objectivity, which means that the authors used maximum information to obtain the objective results. A statistical method was widely used in the work, thanks to which it was possible not only to identify the number of days in which active hostilities were conducted, but also to calculate the average daily losses of soldiers and officers of the Russian army in the Caucasian theater of operations, as well as the average daily losses of senior officers and generals.The authors came to the conclusion that of the five conflicts in which Russia, Turkey and Persia took part in the XIX century, the longest was during the Russian-Persian-Turkish war of 1803–1813, which consisted of 291 days of active hostilities. In second place in terms of duration was the Russian-Turkish war of 1877-1878 – 249 days. In third place is the Russian-Persian War of 1826−1828 – 225 days, on the fourth – the Eastern War of 1853−1856 – 175 days, and the shortest in terms of the number of active combat days was the Russian-Turkish war of 1828–1829 – 73 days.By degree of bitterness, namely, the average daily losses of soldiers and officers of the Caucasian troops, in the first place was the Eastern War of 1853−1856, in the second – the Russian-Turkish war of 1877−1878, and in the third – the Russian-Turkish war of 1828–1829. If we talk about the losses of senior officers and generals, then here the greatest losses were during the Eastern War, and in second place was the Russian-Turkish war of 1828–1829, and already in third place was the Russian-Turkish war of 1877–1878.
