in German, the only language that Hitler spoke, should visit Berlin to meet Hitler to tell him that an Anglo-German rapprochement was still possible. On 17 July 1939, Helmuth Wohlthat, Hermann Göring's deputy in the Four-Year Plan Organisation, attended the meeting of the International Whaling Conference in London as part of the German delegation, and the next day, he and Dirksen met Sir Horace Wilson, the Chief Industrial Adviser to the Government and one of Chamberlain's closest friends. Wilson decided to talk to Wohlthat of the Four-Year Plan Organisation, rather than the Auswärtiges Amt since the latter was run by the Anglophobic Ribbentrop. Without informing Ribbentrop, Dirksen allowed the Wilson-Wohlthat meetings in London to go ahead in which Wilson offered that in an exchange for a German promise not to attack Poland and a "renunciation of aggression in principle" as a way of solving international disputes, he would agree to an Anglo-German nonaggression pact, a "delimitation of spheres of influence" in Europe and a plan for the "international governance" of Africa in which all of the European great powers would jointly administer Africa. However, Wilson clarified to Wohlthat that he regarded Germany as the source of the tension between Germany and Poland by laying claim to Danzig and that the onus was on the Reich to reduce tension with Poland, not the other way around. Halifax told Dirksen much the same thing at the same time. Dirksen and Wohlthat argued that Wilson and another British civil servant, Robert Hudson, had given them a memorandum, "Programme for German-British Cooperation", but Wilson denied having given them such a document, and Wilson's account of the meeting to the Foreign Office suggested that neither Wohlthat nor Dirksen seemed very serious, as both expected all of the concessions to come from Britain, with Germany making none. On 20 July 1939, Hudson, of the Department of Overseas Trade, visited the German embassy to meet Dirksen and Wohlthat. Hudson, an ambitious civil servant and former Conservative MP who was addicted to intrigue, acted on his own in the hope of scoring a great success to help his otherwise-stalled career. In a somewhat-vainglorious account of his meeting at the German embassy, Hudson spoke of about having Danzig rejoin Germany if the latter promised to leave Poland alone. According to Hudson's notes, in exchange for a German promise not to invade Poland and for ending the Anglo-German arms race,
