WWII history ~ I am fairly sure I read in my book "Pursuit" that the Rodney scored a direct hit on Bismarck's Citadel with one of her 16" A.P.C projectiles wrecking it along with effectively killing everyone in there.[/QUOTE]Bismarck was a heavy cruiser. She achieved her speed and heavy armament at the expense of armor. Her citadel was protected by 7-8" armor, for instance.
