The German mines, industry and railroads continued to work, albeit at a reduced pace right up to March 1945. As the Soviets devastated Silesia and the Western Allies captured the Rhur, the Germans had only central Austria and Bohemia left, and they could not provide enough to support what little rag tag of an army they had left. However, stockpiles and depots were enough to fuel the German armies for another month.

Gasoline was at a critical low already in Februaryt 1945, but the Luftwaffe had practically ceasxed to exist and did not need any supplies, and there were no long-range fuel intensive manouvres.

I mean the last few days and the days after the capture of Berlin. There was a final push at one point in Berlin of 10,000 troops to try and break free...that is a lot of resources and logistics...is it all from dumps, stores and reclaimed stuff?
