Alone on the Kreuzberg 20 cannons were put up directing towards the approaching French "Armée de Berlin" under Oudinot. However, with the Allied "Northern Army" under Crown Prince Charles XIV John of Sweden defeating the French already in the Battle of Großbeeren on August 23, the sconce was never used for defence and was later called "Lärmkanonenschanze" (noise cannon sconce). Already in September 1813 the sloppily constructed huts of the citadel collapsed.
