How interested Göring truly was in winning the war in Stalingrad and the success of the airlift...
After Göring visited Hitler at the Berghof on the 22d Nov, he departed for Paris in “Asia,” his luxurious command train. He spent the next four days—when he should have been organizing the airlift—visiting Parisian art dealers and galleries. Von Richthofen was appalled. “I urge Jeschonnek and Zeitzler to report my views to the Führer,” he wrote in his diary on the 25th, “and to harness the Reichsmarschall, but he's in Paris!” Göring arrived back at Hitler's headquarters in Rastenburg on the 27th...( this quoted from about the middle of the page )
