The image is a photograph of a plaque on a wall. The plaque is rectangular in shape and has a beige background. On the left side of the plaque, there is a quote written in black text that reads, "She went down in twelve minutes and not a soul aboard was lost." Below the quote, it reads "The Cairo was the first armed vessel in the history of warfare to be sunk by a torpedo (today called a mine). Torpedoes had been placed in the Yazoo River by Acting Masters Zedekiah McDaniel and Francis M. Ewing of the Confederate Navy. They were detonated from the shore by volunteers placed in camouflaged torpedo pits behind the levee." The quote is attributed to Admiral David Dixon Porter.
