The German public was not officially told of the impending disaster until the end of January 1943, though positive media reports had stopped in the weeks before the announcement. Stalingrad marked the first time that the Nazi government publicly acknowledged a failure in its war effort. On 31 January, regular programmes on German state radio were replaced by a broadcast of the sombre Adagio movement from Anton Bruckner's Seventh Symphony, followed by the announcement of the defeat at Stalingrad. On 18 February, Minister of Propaganda Joseph Goebbels gave the famous "Sportpalast" speech in Berlin, encouraging the Germans to accept a total war that would claim all resources and efforts from the entire population.
