Yup. Yes sir. Cooled the place down REAL NICE. Especially considering that "high tech" for the day involved vacuume tubes, ie; *HEAT SOURCE* from hell. Bismarck survivors recounted "shredding" and horrific injuries to gun crew + coming topside to wonder why perfectly good guns weren't firing. Oooops. Dead FC crew. Rodney's hit - lucky or otherwise - never destroyed Anton and Bruno. It merely jammed both mounts. But did it really?
A graze or near miss would have spewed molten slag and "pellets" that showered the hapless director crews. Consider the round that passed through POW's bridge: you remember, the one that killed all hands but Capt. Leach? Twas "pellets" shrapnel that did the deed. Original thinking of the day was that the covers protected the gear when not in use, but during combat, removal allowed better visuals of the tactical situation; similar to British "open bridges".
As Texas and her sisters were of similar vintage, perhaps it was the plan for the day?
