Operation Clausewitz was the code word initiating the defence of Berlin by Nazi Germany during the final stage of the European Theatre of World War II. Clausewitz was established in the 9 March 1945 document, "Basic Order for the Preparations for the Defense of the Reich Capital" (), a 33-page document containing 24 separate points. The second point of the document, in full (translated) is: "The Reich capital will be defended to the last man and to the last bullet." It has been referred to as the Nazis' last stand against the Soviets.
