The corps headquarters formed in the
Transbaikal Military District in September 1939. It was commanded by Major General
Trofim Kolomiets, its second and last commander, from 29 November 1939. On 22 June 1941 the corps included the
46th and
152nd Rifle Divisions and was part of the
16th Army. The corps and the 16th Army were transferred west and became part of the
Southwestern Front in late June. On 2 July they were transferred to the
Western Front after the German breakthrough in the
Battle of Białystok–Minsk. The units of the corps were committed in attempts to recapture
Smolensk in mid-July. As the 152nd Rifle Division was placed under direct army control, the corps headquarters was left with only the 46th Division under its control by 17 July. The corps headquarters was disbanded on 15 August 1941 as the Red Army eliminated most corps headquarters due to command and control difficulties. == Second formation ==
