Here the 'B' turret shows evidence of a direct hit between the gun barrels, and damage to the turret roof.
See that dark circle at about 8:00 O'clock from the right-side gun barrel?
That's a hole punched in the armor by a high-calibre shell.
The missing section of the gunhouse ( turret ) roof is where the resulting detonation blew the armor ( several inches thick ) off.
You don't want to know what happened to the men inside...
