Who beside Churchill and Patton was concerned about Soviet occupation?
Evidently, I should have used a different wording. My comment about casualties/occupation was in respect to Soviet casualties in taking Berlin and how through the cold war, western documentary producers and authors seemed to steadily up the count to the point where I was hearing numbers of over 1 million for a two week battle.
Post-Soviet era, I've never tried to determine if any researchers produced BoB casualty figures from Soviet archives.
