Later in autumn 1919 the forts were unsuccessfully attacked by the 1st Division of the Estonian Army, supported by bombardment by HMS "Erebus". In 1921 the guns of the fort bombarded Kronstadt during the rebellion. During World War II the fort played a vital part in defending the Siege of Leningrad and maintaining the Oranienbaum Bridgehead. The fort was decommissioned in 1960 and partially demolished. The local authorities of the St Petersburg region are discussing whether to convert the site into a military museum.
