A memo titled W.Wette/G.Ueberschär "Unternehmen Barbarossa" from L OKW/WFSt from September 21st, 1941, expands on the above.
- Take the city, as we have done with other large Russian cities.
Declined, as then we would be tasked with feeding the population.
- Surround the city with a tight ring, and preferably an electrified fence, which would be guarded by machinegunners.
Deficiency: of the two million citizens, the weak will die, and the strong will control their supplies, and remain alive. There is a danger of an epidemic that will transfer to our front. Additionally, we do not know if our soldiers are willing to shoot at women and children attempting to break out.
- Women, children, and old men should be removed, the rest left to starve in the city.
- The expulsion through Volhov and into enemy lines is preferable, but impractical. Who is going to control and direct the hundreds of thousands? Where will the Russian front be then?
- If they cannot be expelled past the Russian front, they should be distributed among captured territories.
In any case, there is the possibility that the survivors will be the bearers of an epidemic and will hold in the city for a long time.
- After the Finns advance and encircle the city, retreat past the Neva and transfer all territories to the north of it to the Finns. The Finns unofficially requested tat they would like to have their border at the Neva, and that Leningrad must vanish. This is a good political outcome. However, the Finns cannot solve the issue of the population. We must do that.
- We announce to the world that Stalin defends Leningrad as a fortress, and thus we must treat it as a military installation. Nevertheless, we will appear merciful, and allow Roosevelt to supply the imprisoned citizens with food using neutral ships supervised by the Red Cross, which we will provide free transit to. Of course, we will not do so, only announce this from a propaganda standpoint.
- Leningrad must be tightly encircled and destroyed with artillery and aircraft (initially available aircraft are insufficient).
- When the terror and hunger grips the city, a limited number of unarmed civilians will be released through individual openings, and either deported into the depths of Russia or spread out among captured territories.
- The fortress garrison is left to itself for the winter. We will enter in the spring. If the Finns enter earlier, no objections will be made. Everything in it will be either captured or deported deep into Russia. Leningrad will be levelled with explosives, and the territory north of the Neva given to the Finns."
The excuse of bombs in Kiev is given, but Hitler has already expressed his desire to level Moscow and Leningrad long before then.
