Krakovetsky appointed two representatives, stabskapitän Frizel in West-Siberian Military District and praporshchik Kalashnikov (both members of SR Party).
On May 30 a meeting took place in Novonikolaevsk, the so-called "Council of representatives of PGAS", which organized the provisional Western Siberian Commissariat.

After several crushing defeats at the hands of the resurgent Red Army, the Eastern front largely collapsed, and dissolved by November 1919.
