Alexander Simplot (1837-1914) was an Iowa artist who applied to Harpers Weekly and became an artist/correspondant serving the far-away Trans-Mississippi. This 7” X 11½” pencil sketch chronicals the spiking of Confederate guns above Island No. 10 by sailors and marines. Simplot was an eye witness to the event and his drawing shows an amazing amount of detail including the actual spiking, musket fire and a tinclad in the distance.
