Very rare album of 70 photographic prints of the Russo-Japanese War by George Henry Rogers, operator and the war correspondent of the Charles Urban Trading Co. He has made his application from Paris. Here he waited three months before a permit to go to Russia was granted. After waiting three weeks in St. Petersburg, he was allowed to proceed as far as Irkutsk. At this town, he was turned out of the train, on the ground that transport was needed for the military for war stores. So Mr. Rogers bought a sledge and three ponies, and fortunately falling in with a troop of cossacks arrived, after seventeen days travelling, at Harbin where he was by the end of April (source: http://www.imdb.com/title/tt0821146/plotsummary). During that time, George H. Rogers managed to film the newsreel "The Russian Army in Manchuria" as well as took photos that were included in the album entitled "The Bioscope, with the Russian Army in Manchuria." Photographs captured scenes of the war including Russian troops in Irkutsk; Generals Kuropatkin, Grekov and Rennenkempf; reservists getting on the train; Russian infantrymen; a Cossack division; General Kuropatkin with viceroy of Mukden; General Kuropatkin in Harbin; beheading of prisoners; photographs of Rogers. There is an inscription in French: "Dédié Respectueusement a mm. les Généraux Rennenkampf et Grekoff en témoignage de remerciement pour leur courtoisie envers l'auteur, qui a suivi les troupes russes en mandchourie depuis le commencement de la guerre. G. H. Rogers Janvier 1905."

The collection includes Pli︠u︡shchevskiĭ-Pli︠u︡shchik's diaries for 1905-1909 (covering the Russo-Japanese War, and the 1905 Revolution) and 1914-1920 (covering World War I, the 1917 Russian Revolution and the Civil War). Among other manuscripts are a memorandum prepared by General Denikin's staff for the allied missions upon their arrival in Ekaterinodar (Nov. 1918) and Pli︠u︡shchevskiĭ-Pli︠u︡shchik's obituary of General Ivan Romanovskiĭ.
