The police were not able to handle the situation alone, and the soldiers were called upon. These were Cossacks and recently trained. There was bad feeling between the police and the Cossacks, and so the Cossacks were inclined to listen to the people and to become friendly with them. On Sunday, March 11, the factory hands planned to make a great demonstration. The Tsar, learning of it, ordered notices to be posted warning the people that if they gathered, the soldiers were ordered to fire upon them. A few people did gather, and they were fired upon by machine guns and several were killed. The next morning, the officers who had ordered the soldiers to fire upon the people were killed by their own men. Then notices were posted by the government saying that unless the rioters went to work, they would immediately be sent to the front. Other regiments revolted, and there was a battle between these and the few who remained loyal to the government. It was not a serious battle; but some were killed and the loyal regiments were defeated. Then soldiers and people ran through the streets crying, "Down with the Government." The Tsar was at the front. Had he been in Petrograd, he might have saved the government by making some new promises; but, as it was, it soon fell. As soon as the government was overthrown and the Tsar taken prisoner, those who had long sought for a revolution and had been forced to flee from Russia, came rushing back from Switzerland, Greece, France, and the United States. They were the real leaders after they arrived. An American who was in Petrograd at the time gives the following account of the revolution: Their first demand was that all prison doors should be opened and that the oppressed the world over should be freed. The revolution was picturesque and full of color. Nearly every morning one could see regiment after regiment, soldiers, Cossacks, and sailors, with their regimental colors, and bands, and revolutionary flags, marching to the Duma to take the new oath of allegiance. They were cheered; they were blessed; handkerchiefs were waved; hats were raised, as marks of appreciation and gratitude to these men, without whose help there would have been no revolution. The enthusiasm became so contagious that men and women, young and old, high and low, fell in alongside, or behind, joined in the singing of the Marseillaise, and walked to the Duma to take the oath of allegiance, and having taken it, they felt as purified as if they had partaken of the communion.
