Hitler's inner circle became acutely aware of his intentions regarding Poland early in the war. On September 9, Colonel Eduard Wagner recorded in his diary a conversation he had with General Halder, the Army Chief of Staff, wherein they discussed the plans for the future of Poland. The gravity of their discussion highlighted the sinister goals that Hitler and Goering had in mind for the Polish nation.

Wagner's remarks indicate a chilling resolution to annihilate the Polish people, suggesting that such intentions were not just military strategies but aimed at complete extermination. His writings reflect the urgent need to keep these discussions discreet, emphasizing the atrocities that were being planned against Poland during this dark period of history.
