I guess you’re right... something about the way it was worded just irked the crap out of me.
One controversial account—states that the Monitor was sunk by a submarine! A steam powered Rebel submarine what used a mine to sink the ironclad. The blast sank the sub but the Rebel Captain escaped and was captured by a Yankee Gunboat. I believe it was the CSS Captain Sterling. If they recover the Monitor—they might find the sub resting near her. It had a 3 man crew—used a steam engine—to build up steam—the fires were put out and the compressed steam used to power it for a limited run under water. If true it would re-write naval history.
