After the failure of the Nivelle Offensive, and with Russia collapsing into chaos, the British Cabinet unleashes Haig, who begins his latest offensive.
By autumn of 1917, the Russian Provisional Government had failed. It lost popular support, the Army was collapsing, and the Germans were advancing on Petrograd. Lenin determined it was time for the Bolsheviks to make their move.
Following the July Days, Alexander Kerensky became convinced that the biggest threat to his government now loomed on the political right, and he became increasingly suspicious of the new army commander-in-chief, Lavr Kornilov.
The Kerensky Offensive was supposed to prove that the Russian Provisional Government was in control and that Russia could still field an effective army. Instead, it demonstrated that neither of these were true.
The Kerensky Offensive provoked discontent among soldiers in Petrograd which triggered a Bolshevik uprising against the Provisional Government. The uprising was put down and evidence was made public that the Bolsheviks were being supported and funded by Germany.
