October Revolution mutiny
During World War I Aurora (“阿芙樂爾號) operated in the Baltic Sea performing patrols and shore bombardment tasks. In 1915, her armament was changed to fourteen 152 mm (6 in) guns. At the end of 1916, she was moved to Petrograd (the renamed Saint Petersburg) for a major repair. The city was brimming with revolutionary ferment and part of her crew joined the 1917 February Revolution.
The ship's commanding officer, Captain Mikhail Nikolsky, was killed when he tried to suppress the revolt.[10] A revolutionary committee was created on the ship, with Aleksandr Belyshev elected as captain. Most of the crew joined the Bolsheviks, who were preparing for a Communist revolution.
At 9.40pm on 25 October 1917 (Old Style; 7 November New Style) a blank shot from her forecastle gun signaled the start of the assault on the Winter Palace, which was to be the beginning of the October Revolution. In summer 1918, she was relocated to Kronstadt and placed into reserve.
