months prior to the beginning of World War II in 1939, German newspapers and leaders had carried out a national and international propaganda campaign accusing Polish authorities of organizing or tolerating violent ethnic cleansing of ethnic Germans living in Poland. British ambassador Sir H. Kennard sent four statements in August 1939 to Viscount Halifax regarding Hitler's claims about the treatment Germans were receiving in Poland; he came to the conclusion all the claims by Hitler and the Nazis were exaggerations or false claims. From the beginning, the invasion of Poland by Nazi Germany was intended as fulfilment of the future plan of the German Reich described by Adolf Hitler in his book Mein Kampf as Lebensraum ("living space") for the Germans in Central and Eastern Europe. The goal of the occupation was to turn the former territory of Poland into ethnically German "living space", by deporting and exterminating the non-German population, or relegating it to the status of slave laborers. The goal of the German state under Nazi leadership during the war was the complete destruction of the Polish people and nation. The fate of the Polish people, as well as the fate of many other Slavs, was outlined in genocidal Generalplan Ost (General Plan for the East) and a closely related Generalsiedlungsplan (General Plan for Settlement). Over a period of 30 years, approximately 12.5 million Germans would be resettled in the Slavic areas, including Poland; with some versions of the plan requiring the resettlement of at least 100 million Germans over a century. The Slavic inhabitants of those lands would be eliminated as the result of genocidal policies; and the survivors would be resettled further east, in less hospitable areas of Eurasia, beyond the Ural Mountains, such as Siberia. At the plan's fulfillment, no Slavs or Jews would remain in Central and Eastern Europe. Generalplan Ost, essentially a grand plan to commit ethnic cleansing, was divided into two parts, the Kleine Planung ("Small Plan"), covered actions which would be undertaken during the war, and the Grosse Planung ("Big Plan"), covered actions which would be undertaken after the war was won. The plan envisaged that different percentages of the various conquered nations would undergo Germanization, be expelled and deported to the depths of Russia, and suffer other gruesome fates, including purposeful starvation and murder, the net effect of which would ensure that the conquered territories would take on an irrevocably
