The 20 July Plot, codenamed Operation Valkyrie, represents a pivotal, albeit failed, attempt by a clandestine group of German military officers to assassinate Adolf Hitler and overthrow the Nazi regime. This audacious act, driven by a desperate desire to end the war and the atrocities of Nazism, faced immense internal and external opposition. The plotters operated within the highly controlled and paranoid environment of Hitler's inner circle, where betrayal and discovery were constant threats, and their success hinged on precise timing and unwavering execution against a leader who had already survived multiple assassination attempts.

The existing description highlights the daring nature of the 20 July Plot and its near-mythic status in historical accounts. It notes the existence of numerous factual and fictional works, as well as dramatizations, that have explored this event. The description specifically references the accuracy and acclaim of the film 'Valkyrie,' suggesting a high standard for historical representation of the plot. The inclusion of authors Mark Stacey and Neil Short, along with illustrator Peter Dennis, indicates a work that likely combines rigorous historical research with detailed visual documentation.
