Revolution broke out in Russia, and was centered in Petrograd, the capital. General Alekseyev proposed to send a detachment by its commander with full power, to restore order in the capital. The tsar then ordered to allocate an infantry and cavalry brigade from the Northern and Western Fronts, and appointed Ivanov as the head of the general-adjutants and commander-in-chief of the Petrograd Military District, replacing Lieutenant-General Sergei Khabalov. Later on, the tsar ordered him to take command of the St. George Battalion in Tsarskoye Selo to ensure the royal family's safety. There was also a speech of the Stavka about strengthening the Petrograd Garrison by allocating "strong regiments" from the front back to the capital. Later, when the soldiers and police loyal to the Imperial Government surrendered to the revolutionaries, Minister of War General Mikhail Belyaev declared Petrograd a stage of siege, and military operation against the revolutionaries in the capital had begun. General Alekseyev ordered Northern Front commander-in-chief General Yuri Danilov to send Ivanov two infantry and two cavalry regiments, reinforced by a machine-gun team: The Western Front informed General Alekseyev about dispatching the 34th Sevsky and 36th Orlovsky Infantry Regiments, the 2nd Hussar Pavlograd and the 2nd Don Cossack Regiments during February 28 and March 2. The Northern Front singled out the 67th and 68th Infantry Regiments, the 15th Ulansky Tatar and the 3rd Ural Cossack regiments.
