“At this time a high-ranking SS leader hinted to me that Himmler was preparing decisive steps. In February 1945, the Reichsführer-SS had assumed command of the Vistula Army Group, but he was no better than his successor at stopping the Russian advance. Hitler was now berating him also. Thus what personal prestige Himmler had retained was used up by a few weeks of commanding frontline troops. Nevertheless, everyone still feared Himmler, and I felt distinctly shaky one day on learning that Himmler was coming to see me about something that evening. This, incidentally, was the only time he ever called on me. My nervousness grew when Theodor Hupfauer, the new chief of our Central Office- with whom I had several times spoken rather candidly- told me in some trepidation that Gestapo chief Kaltenbrunner would be calling on him at the same hour. Before Himmler entered, by adjutant whispered to me: "He's alone." My office was without window panes; we no longer bothered replacing them since they were blasted out by bombs every few days. A wretched candle stood at the center of the table; the electricity was out again. Wrapped in our coats, we sat facing one another. Himmler talked about minor matters, asked about pointless details, and finally made the witless observation: "When the course is downhill there's always a floor to the valley, and once it is reached, Herr Speer, the ascent begins again." Since I expressed neither agreement nor disagreement with this proverbial wisdom and remained virtually monosyllabic throughout the conversation, he soon took his leave. I never found out what he wanted of it, or why Kaltenbrunner called on Hupfauer at the same time. Perhaps t hey had heard about my critical attitude and were seeking allies; perhaps they merely wanted to sound us out.”
