During the July Days, Donskoy at early hours of July 17 called to the leader of the Left Socialist-Revolutionaries in the Tauride Palace to discuss the organization of the military protest and later announced it at the Kronshtadt City Council. Along with Nikolai Rivkin, Donskoy led a combined squat of Baltic sailors against the Kornilov's protest. During the October Revolution Boris Donskoy was a commissar at the Fort Ino, just outside Saint Petersburg, from where he directed military formations to the Pulkovo Heights.
