But "to put a stop" to the revolution was no longer possible. On the 4th Company of the Reserve Battalion of the Pavlovsky Regiment opened fire, not on the workers, however, but on squads of mounted police who were engaged in a skirmish with the workers. A most energetic and persistent drive was made to win over the troops, especially by the working women, who addressed themselves directly to the soldiers, fraternized with them and called upon them to help the people to overthrow the tsarist autocracy. The practical work of the Bolshevik Party at that time was directed by the Bureau of the Central Committee of the Party which had its quarters in Petrograd and was headed by Vyacheslav Molotov. On February 26 (March 11) the Bureau of the Central Committee issued a manifesto calling for the continuation of the armed struggle against tsardom and the formation of a Provisional Revolutionary Government. On the troops in Petrograd refused to fire on the workers and began to line up with the people in revolt. The number of soldiers who had joined the revolt by the morning of March 12 was still no more than 10,000, but by the evening it already exceeded 60,000. The workers and soldiers who had risen in revolt began to arrest tsarist ministers and generals and to free revolutionaries from jail. The released political prisoners joined the revolutionary struggle. In the streets, shots were still being exchanged with police and gendarmes posted with machine guns in the attics of houses. But the troops rapidly went over to the side of the workers, and this decided the fate of the tsarist autocracy. When the news of the victory of the revolution in Petrograd spread to other towns and to the front, the workers and soldiers everywhere began to depose the tsarist officials. On , the liberal members of the Fourth State Duma, as the result of a backstairs agreement with the Socialist-Revolutionary and Menshevik leaders, set up a Provisional Committee of the State Duma, headed by Rodzyanko, the President of the Duma, a landlord and a monarchist. And a few days later, the Provisional Committee of the State Duma and the Socialist-Revolutionary and Menshevik leaders of the Executive Committee of the Soviet of Workers' and Soldiers' Deputies, acting secretly from the Bolsheviks, came to an agreement to form a new provisional government of Russia, headed by Prince Lvov. The Provisional Government included Milyukov, the head of the Constitutional-Democrats, Guchkov, the head of the Octobrists and the Socialist-Revolutionary Kerensky amongst others.
