Hitler was woken up just after midnight and met with Birger Dahlerus and Göring. Dahlerus later recalled Hitler as appearing glassy-eyed and highly agitated, at one point going on a bizarre rambling monologue repetitively asserting that Germany could win a rapid war and that he would "build U-boats, build U-boats, U-boats, U-boats, U-boats" and "airplanes, airplanes, airplanes, and I shall annihilate my enemies." After calming down Hitler laid out a set of proposals more detailed than Nevile Henderson had been given, which included annexation of Danzig and the Polish Corridor.

Germany was reminded that "His Majesty's Government have obligations to Poland by which they are bound and which they intend to honour. They could not, for any advantage offered to Great Britain, acquiesce in a settlement which put in jeopardy the independence of a State to whom they have given their guarantee." Britain suggested that the next step "should be the initiation of direct discussions between the German and Polish Governments on a basis which would include the principles stated above, namely, the safeguarding of Poland's essential interests and the securing of the settlement by an international guarantee." The reply concluded with a warning that failure to reach a settlement "would ruin the hopes of better understanding between Germany and Great Britain, would bring the two countries into conflict, and might well plunge the whole world into war. Such an outcome would be a calamity without parallel in history."[55]
Hitler read a German translation of the British government's note and told Henderson he was willing to negotiate, but Poland could not be reasonable. Henderson firmly replied that Hitler would have to choose between war with Poland or friendship with Britain. Hitler said he would prepare a written reply of his own.[71]

Nevile Henderson handed Joachim von Ribbentrop the British government's reply at midnight. "His Majesty's Government repeat that they reciprocate the German Government's desire for improved relations, but it will be recognised that they could not sacrifice the interests of other friends in order to obtain that improvement", the note explained. "They fully understand that the German Government cannot sacrifice Germany's vital interests, but the Polish Government are in the same position and His Majesty's Government believe that the vital interests of the two countries are not incompatible." The note expressed "reservation in regard to the statement of the particular demands put forward" by Germany, but said that German proposals would be "fully examined" during discussions.[77]
