"German troops crossed the frontier and marched on Vienna... As luck would have it, Goering was giving a monster party at the Haus der Flieger that night [11 March 1938]... News of the Austrian coup had reached the guests... As usual after a coup, the Germans showed signs of nervousness and did all they could to reconcile foreign opinion. Goering at once took Henderson into a corner and urged him to use his good offices to see that peace was not broken. He even sought to placate Mastny, the Czech Minister in Berlin, to whom he gave his word of honour that events in Austria would have no detrimental effect on relations between the Reich and Czechoslovakia. He then sought out the Minister again and repeated the assurance, adding that he was able to give Hitler's word as well. It was a perfect example of Nazi technique. First you brutally assault a man; then you rush round to his neighbours to express the pious hope that there will be no breach of the peace, particularly since you do not intend to assault them."
