Just to make sure that we are on the same page about what happened at St. Charles I don't know if I gave you enough information in order to locate the Union reports that I was talking about.

As I stated they are located in the Official records of the Union and Confederate Navies in the War of the Rebellion. / Series I - Volume 23: Naval Forces on Western Waters (April 12, 1862 - December 31, 1862) Starting on page 165. They are located online at http://cdl.library.cornell.edu/moa/browse.monographs/ofre.html
