The Confederate War Department, at least, is alert to the danger. As John Beauchamp Jones says in his diary entry today.
“Pemberton permitted one iron-clad gun-boat to pass, and all our boats below are now at its mercy.”

Thanks, I missed that. Pemberton was in a post too big for him. (A “what if” I think of sometimes is what if the “Arkansas” had survived.)
