 == Giorgi Kazbegi  == 

 I am from ru.wiki (you use my article about gen. Kazbek). 

 ""He was appointed Chief of Staff of the Warsaw Fortress in 1891 and promoted to major-general on October 29, 1892"" - no, he was promoted and apointed the same day, October 29 1892. November 11 1887 - 29 October 1892 he was commander of 51 Infantry Litovsky regiment.  

 ""Kazbegi then served as Chief of Staff of the Ivangorod Fortress from 1899 to 1902, when he received the rank of lieutenant-general and appointment as Chief of Staff of Warsaw Military District. In 1905, he was made governor-general of Khabarovsk and commandant of Vladivostok. He served in this capacity during the Russian Revolution of 1905, which saw his promotion to the rank of general of infantry"" - it's number of mistakes of Gogitidze. 

 After Warsaw Fortress gen. Kazbek was: 

 General-quartermaster of Staff of Warsaw military district (March 27 1897 - July 3 1899) (he never was head of staff of this district) 

 Commandant (not head of staff) of Ivangorod Fortress (July 3 1899 - June 23 1902). Lieutenant-General (promoted January 1 1901, with seniority since December 6 1900) 

 Commandant of Warsaw Fortress (June 23 1902 - January 25 1905) 

 Commandant of Vladivostok Fortress (January 25 1905 - March 7 1906) 

 At disposal of Commander-in-chief on Far East (March 7 1906 - December 14 1906) 

 Attached to Chief Staff (December 14 1906 - September 25 1907) 

 September 25 1907 - promoted to General of Infantry and put to retire with uniform and pension  

 ""his 37 years of military service"" - according to ""Список генералам по старшинству"", he was on military service since 1860, so - 47 years, not 37.  

 And Ivane Kazbegi - it's mistake of Gogitidze, his name was Иван Николаевич, not Иван Георгиевич (Gogitidze wrongly made him the son of general Georgy).   "
