Also from my notes today:
Lost in the news of the German invasion of the Soviet Union there is also some news on the atomic development front. G. P. Thompson drafts a final report on the MAUD Committee's determination of the possibility of a fast neutron bomb.
But enough of that, back to the war in Russia.
L.Z. Mekhlis is appointed Chief of the Red Army's Main Political Directorate, a position of political watchdog over the Soviet officer corps.
Lieutenant-General K.D. Golubev's 10th Army tries to make a counter attack against German forces, but to no avail. Within days, the 10th Army would no longer exist.
Major-General Karpezo's 15th Mechanized Corps manages to commit only a weak forward detachment from his 10th Tank Division to attempt to counterattack Kleist’s forces.
Upon war with Germany, the Soviets quickly formed a wartime national command structure from its existing Peoples' Commissariat of Defense [Narodnyi komissariat oborony - NKO] and the Red Army General Staff [General'nyi shtab Krasnoi Armii - GshKA] by forming headquarters [Stavka] of the Main Command [ Stavka Glavnogo Komandovaniia - SGK].
