What were the tactics used in the October Revolution?

Lenin and the Bolsheviks staged a military coup rather than a true revolution on October 25, 1917 to take power away from the Russian Provisional Government. They seized important strategic installations in Petrograd (St. Petersburg), Moscow and other important cities. They railway stations so that troops could not be moved to fight the Bolsheviks. They seized telegraph and telephone centers so that the Provisional Government could not communicate with forces loyal to them. They had already gotten support from Russia's military forces who refused to take action against the Bolshevik takeover. These actions made the Provisional Government unable to defend itself and the Bolsheviks walked into the Winter Palace and arrested the members of the Provisional Government with hardly a shot fired. They then announced to the country that they were now in charge.
