Two post-Civil War photographs of steamboats on the Mississippi River at St. Louis, Missouri; one includes a bridge spanning the river into Illinois; the other features a loading and unloading area with supplies in the foreground. St. Louis was a major supply port for the Union forces in the Trans-Mississippi Theatre. Following the fall of Vicksburg, the Mississippi River was open to Union ship traffic all the way from its source to the Gulf of Mexico.
