Yesterday Petrograd seemed to be enduring a second revolution, with radical workers, soldiers and Kronstadt sailors looking like they were about to overthrow the Provisional Government and hand power to the Petrograd Soviet. The radicals controlled the streets and there was no power in the city that could resist them. However the Soviet leaders declined the power offered to them and the revolutionary tide began to ebb.
Now the fortunes of the Provisional Government are once more in the ascendant. Loyalist troops arrive on the streets of Petrograd and begin to take control from the radicals.
The loyalist soldiers have been turned against the Bolsheviks by shocking reports now beginning to appear in the newspapers, alleging that Lenin is none other than a German agent, based on the testimony of an escapee from a German prisoner of war camp and on the Germans having let Lenin travel through Germany on his special train.
Realising that a reactionary crackdown is imminent the Bolshevik leadership prepares to go into hiding. The Kronstadt sailors are persuaded to abandon the Peter and Paul Fortress. They return to their base while demonstrators drift back to their homes and radical soldiers to their barracks.
