Many of these shells were fired at the two 305 mm twin-gun armored turrets of the Maxim Gorkii coastal defense battery, http://www.allworldwars.com/The%20History%20of%20Maxim%20Gorky-I%20Naval%20Battery.html, retrieved on 13 January 2009 although shells fired at the turrets had little effect other than to jam one of the turrets and possibly knock out electrical power to the turrets, both of which were repaired without too much trouble.
