Germany, Planning

After failing to achieve aerial supremacy over southern England, Hitler decides to suspend Operation Sealion. The Allies learn of this through an intercepted Enigma signal. Meanwhile, General Friedrich von Paulus, the Deputy Chief of the Army General Staff, presents a further plan for the attack on the Soviet Union. This version envisages three thrusts for Leningrad, Moscow and Kiev, but the emphasis is still on the central advance to the Soviet capital. Further consideration over the coming weeks confirms to the General Staff that the priority is correct (see December 5).

Rumania, Home Front

Antonescu requests a German Military Mission in Rumania for the purpose of modernizing the Romanian Army, specifically with tanks and artillery. In return he promises Hitler that his forces will be deployed on the Russian, not the Hungarian border.

The first German units arrive in the country on October 7. In total 22,430 military personnel will be deployed to Rumania, of whom 17,561 will be from the army. By mid-November the 13th Motorized Infantry Div, 4th Panzer Regt, engineers, signal troops and anti-aircraft detachments, plus 6 fighter and 2 reconnaissance Luftwaffe squadrond, had arrived in the country.

Unknown to either Antonescu or the mission members, on September 19 the OKW issued a statement detailing specific tasks of the mission in Rumania: to protect the Ploesti oil fields from a third party, to enable Rumania's armed forces to undertake specific missions according to German interests, and to prepare for operations by Axis forces from Romanian territory in the event of a war against the USSR.
