In the fall of 1919, Pyotr Wrangel, the general of a White Russian army launched an offensive to capture Moscow from Bolsheviks as they were too busy fighting Alexander Kolchak in Siberia. But in our real timeline, it got repelled and he was pushed back. Can someone come up with a good realistic scenario of how Anton Denikin successfully captures Moscow and causes the end of the whole Russian Civil War for the Bolsheviks? And what happens after the defeat of the Reds?
