I have a suggestion, If I may>
Along with the information you put together on the events relating to Sumter, why not include a section to include how the information and views from:
Allegiance-Forts Sumter, Charleston, and the Beginning of the Civil War-David Detzer
Days of Defiance-Sumter, Secession, and the Coming of the Civil War- Maury Klein
vary from the material you find.
In other words, explain where they got it Wrong!...or Right, as the case may be.
