Stauffenberg took part in the Invasion of Poland, the 1941–42 invasion of the Soviet Union in Operation Barbarossa and the Tunisian campaign during the Second World War. Alongside Major Generals Henning von Tresckow and Hans Oster, he became a key figure in the German resistance to Nazism within the Wehrmacht.
On 20 July 1944, Stauffenberg’s assassination attempt failed, the explosive he had placed only dealing Hitler minor injuries. The conspirators were arrested, and many of them executed, including Stauffenberg on the day after the attempt. His wife Nina was also arrested, giving birth to their fifth child Konstanze while imprisoned.
