For Danton, rounds were stored in cases with three rounds per case. Each gun on the 1st deck had 27 ready rounds stowed close to the mountings. Each gun on the main deck had 36 ready rounds. Additional rounds were stored in the magazines. The hoists leading to the guns were slow, and the rate of fire was greatly reduced once the ready rounds were used up.
