All through the spring and summer of 1939 there was a massive media campaign in Germany demanding the immediate return of the Free City of Danzig to Germany under the slogan "Home to the "Reich"!". However, the Danzig crisis was a just a pretext for war. Ribbentrop ordered Count Hans-Adolf von Moltke, the German ambassador to Poland, not to negotiate with the Poles over Danzig as it was always Ribbentrop's great fear that the Poles might actually agree to the Free City returning to Germany, thereby depriving the "Reich" out of its pretext for attacking Poland. However, the German propaganda that all the "Reich" wanted was to bring Danzig home did some effect abroad. In April 1943, when mass graves of the Polish officers massacred by the NKVD in Katyn Wood were discovered, the Canadian Prime Minister William Lyon Mackenzie King wrote in his diary that it was the Poles who caused the outbreak of the war in 1939 by refusing to give in to Hitler's demand that Danzig be allowed to rejoin Germany, and as such it was the Poles' own fault for the Katyn Wood massacre and everything else they had suffered since 1939. The British historian Victor Rothwell described King's view that the Poles had caused their own suffering as one motivated by spite and his resentment at being pressured by public opinion into declaring war on Germany despite his own inclinations towards neutrality. From distant New Zealand, the Prime Minister Michael Joseph Savage offered to return Western Samoa, which had once been the colony of German Samoa together with the rest of the former German islands in the Pacific held by New Zealand, in exchange for Germany promising not to use violence to alter the status of Danzig.
