Operation Spark (1941)
Operation Spark (sometimes translated as "Operation Flash") was the code name for the planned assassination of Nazi dictator Adolf Hitler by the anti-Nazi conspiracy of German Army officers and political conservatives, known as the Schwarze Kapelle ("black orchestra") during World War II. The name was coined by Major General Henning von Tresckow in 1941. He believed that because of Hitler's many successes up to that time, his personal charisma, and the oath of personal loyalty to him sworn by all German army officers, it would be impossible to overthrow Hitler and the Nazis with Hitler still alive.
