Still , images of the '' Abwehr '' as a veritable organ of resistance inside the heart of the Third Reich are not an accurate reflection across the spectrum of its entire operations or its personnel . There were some committed Nazis in its ranks . Before the invasion of Poland for instance , the '' Abwehr '' and SiPo jointly drew up a list of over sixty-thousand names , people who were to be the targets of Operation Tannenberg , an effort designed to systematically identify and liquidate the Polish elite . For several months before the invasion of the Soviet Union , the '' Abwehr '' was key in deception operations set up to convince the British and the Soviets that Great Britain was under threat of imminent invasion , an undertaking which helped soften the eastern territories for Operation Barbarossa . Before the commencement of the attack on the Soviet Union , the '' Abwehr '' also spread rumours that the British talk of an impending German attack was nothing more than disinformation
