So how did the talks go?
"On March 9, Ribbentrop, the new German Foreign Minister, had arrived in London to wind up his affairs at the embassy, where he had been ambassador. He had long talks with Chamberlain, Halifax, the King and the Archbishop of Canterbury. His impressions of the British Prime Minister and Foreign Secretary, he reported back to Berlin, were "very good." After a long conference with Lord Halifax, Ribbentrop reported directly to Hitler on March 10 as to what Britain would do "if the Austrian question cannot be settled peacefully." Basically he was convinced from his London talks "that England will do nothing in regard to Austria.""
