U.S.S. Cairo

This is a Union Gunboat (one of four that was used) that was sunk (in the Mississippi River)by the Confederate Army using gun power in a barrel (under water) an electric charge, that was set off on by two Confederate Soldier's from land. It sank completely in 12 minutes with 175 soldier's on board, no one died, they got off safely.

The picture at the top is a drawing of (land mine/bomb) what the Confederates used.

They started bringing pieces of the U.S.S. Cairo up from the bottom of the Mississippi in 1960, and since it sank so fast, they got a lot!
