Kerensky-Krasnov Uprising

After the Bolsheviks took Saint Petersburg, Alexander Kerensky led a counter-revolt against the Bolsheviks in nearby Pskov and marched on the city from there.

Fighting
From November 8th Kerensky gathered troops from the countryside. A group of cossacks led by Pyotr Krasnov in Gatchina refused to support the Bolsheviks and joined Kerensky who arrived on November 9th. When Kerensky showed up Pyotr's fighting started between local reds and whites. The red won and Kerensky with his whites were marrooned in the palace. Meanwhile Pyotr managed to take Pskov on November 10th. Kerensky had assigned Pyotr Krasnov as his general and he marched on Saint Petersburg. On November 11th the Junker Mutiny occurred to support Kerensky's offensive. On November 12th he captured Tsarskoe Selo, but was defeated at the Battle of Pulkovo on November 13th.The revolt would end the next day with the fall of Pskov. Kerensky had to flee into exile similar to Lenin before him on the 14th with the palace falling soon after on the next day.

Analysis
His battle despite being little known was key to the future of the new bolshevik government and the anti-bolshevik forces. That decision lay in the hands of a few unprofessional troops and victory was easily possible for either side.
