Jornadas de Julio
The Tsar was threatened with being incarcerated at the Fortress on his return from Mogilev to Tsarskoe Selo on March 8 (O.S.); but he was placed under house arrest. On July 4 (O.S.) during the July Days demonstrations, the Fortress garrison of 8,000 men declared for the Bolsheviks. They surrendered to government forces without a struggle on July 6 (O.S.).
