Le 20 juillet 1944, l'attentat de Stauffenberg contre Adolf Hitler est commis.

On July 20, 1944, a bomb planted by Colonel Claus Schenk Graf von Stauffenberg exploded in the briefing barracks at the Wolfsschanze headquarters in East Prussia. The device was intended to kill Adolf Hitler, marking one of the most dramatic moments of resistance against Nazi rule. The explosion occurred at approximately 12:42 p.m., with Stauffenberg having left the room just before the blast. He believed the Führer dead, as he fled in a military aircraft toward Berlin, where the failed coup attempt known as Operation Walküre had been planned. Operation Walküre was originally conceived by the Wehrmacht as a means to suppress potential uprisings within the Nazi regime. However, the conspirators sought to repurpose it for their own putsch, involving high-ranking military officers, diplomats, and civil servants. Stauffenberg, regarded as the key organizer of this conservative-led rebellion, had previously expressed his belief that killing Hitler was the only option remaining. “There is no other choice but to eliminate him,” he had told close associates days earlier. Despite the initial shock of the attack, Hitler survived with minor injuries. The thick oak table and open windows due to the summer heat helped absorb some of the blast’s force. Nevertheless, the coup quickly unraveled. Delays, missteps, and poor planning contributed to its failure. Some conspirators hesitated under pressure, while others remained passive or even switched sides. By evening, the plot had collapsed entirely. Hitler responded to the attempted assassination by addressing the nation via radio, attributing his survival to divine providence. Within hours, Stauffenberg and several co-conspirators were arrested. That night, they were executed summarily. Others were discovered later, resulting in the deaths of around 200 resistance fighters. Historian Wolfgang Benz attributed the failure largely to the absence of prominent generals such as Erwin Rommel, who refused to participate. “At least one of these leaders should have taken charge,” Benz noted, suggesting that public support might have followed if a respected figure had led the effort. The failed coup became a powerful symbol of resistance against Hitler. Stauffenberg's fellow conspirator, Henning von Tresckow, had already concluded that success was secondary to the act itself. “It is no longer about victory,” he stated, “but about the German resistance movement daring to make a decisive throw, risking lives, before history and the world.” Other acts of defiance had occurred prior to the July 20 plot, including the near-successful bombing of Hitler in Munich in 1939 by carpenter Georg Elser, and the leaflet distribution campaign of the White Rose group. These efforts, however, were overshadowed by the more recent resistance. Benz described the July 20 uprising as part of a delayed but ultimately significant pushback by conservative elites against the Nazi regime. Memorialization of the July 20 plot has evolved over time. Initially, the conspirators were viewed as traitors. Stauffenberg’s widow faced denial of her officer’s pension early on. Over decades, however, recognition grew. Today, streets, schools, and military installations bear their names. Public buildings are adorned with flags on July 20, and ceremonies are held annually for recruits in the German armed forces. The modern military of democratic Germany invokes the legacy of those who resisted Hitler, drawing strength from the courage of Stauffenberg and his compatriots.
