The German Civil War erupted after the success of Operation Spark, which killed Hitler, Himmler, and Goring all at once. Immediately, both Speer and a combination of Bormann and Jodl attempted to form Governments to take over. Meanwhile, the army, now under the control of the rebels, fought against both with the aid of many of the most famed generals, including Rommel, Stauffenburg, and Tresckow.
For several years prior, a group in the Wehrmacht known as the Schwarze Kapelle, or Black Orchestra, had been planning to overthrow the Nazi Government of Germany. Led by Major General Henning von Tresckow and supported by prominent, popular officers including Claus von Stauffenberg and Erwin Rommel. Rommel, though initailly opposed to the idea, declared support for the revolution once it had been effected.
Hitler is Assasinated[]
Operation Spark went into action on July 20th, 1944. As Stauffenburg was able to detonate both bombs (instead of just one as OTL), Hitler, Himmler, and Goering were all killed along with a large section of the German High Command.
