[4] He immediately wrote nine letters in Orašac, in which Karađorđe called on important people to join the insurrection against the occupying forces.
When it became known that the Russians would go to war with the Turks again, negotiations in Iasi became pointless, so the Serbian delegation returned to Belgrade in early April 1809.
After the fall of Deligrad, the Serbian insurgent army was in a great crisis, and on September 14, 1809, Karađorđe transferred all his powers to Janićije Đurić.
[7]In difficult moments, on July 22, 1813, Karađorđe again temporarily transferred the supreme power to Janićije Đurić.
[1] After the defeat of the insurgent army at Zasavica, Đurić fled to Belgrade, and then, together with Karađorđe, he moved to Zemun on October 3, 1813.
[4] He managed to find a way to deliver Russian messages to Karađorđe so that they would remain consistent in their wishes to move to Russia.
[4] When Austrian General Crvenka learned of Đurić's skilful delivery of letters, he called him the Russian spirit.
[1] Karađorđe blamed Metropolitan of Belgrade Leontije Lambrović, and Janicije Đurić of being responsible for the fall of Serbia.
[11] Together with Jakov Nenadović, Luka Lazarević, Petar Dobrnjac and Milenko Stojković, he was in opposition to Karađorđe and supported Prince Miloš Obrenović's strategies and tactics with the Turks.
During his stay in Russia, he began to record the events from the First Serbian Uprising and Karađorđe's biography -- Povešnica od početka vremena vožda srpskog Karađorđa Petrovića (The History from the Beginning of the Time of Serbian Grand Vožd Karađorđe Petrović).
