In his 1974 article "England's Place In Hitler's Plans for World Dominion", Hillgruber argued that, during the Nazi period, German foreign policy went through ten different phases. Hillgruber contended that, during the early phases, Hitler was intent on having the anti-Soviet alliance with Britain he had written of in Mein Kampf and Zweites Buch. By the time of the Hossbach Memorandum of 1937, Hillgruber argued, Hitler was undertaking a course of expansion either "without Britain" or, preferably, "with Britain", but if necessary "against Britain".[46] By the late 1930s, when it became clear that Britain had no interest in his overtures, German foreign policy turned anti-British as reflected in the Z Plan of January 1939 for a gigantic German fleet that would crush the Royal Navy by 1944.
