CSA started on February 4th. Provisional Constitution on February 8th. The Baltimore Plot was in late February, and the alleged perpetrators are not readily identified.
There is also some evidence that there never was any such plot, and the whole thing was made up by the Pinkertons.
So you would blame the Confederate government for a plot which may or may not have even existed, with pretty much no proof at all that any such action was taken by the Confederate government.
You would get an "act of war" out of the possible paranoid suspicions of the Pinkerton gang?
In the book you can see who the conspirators were and the power and influence they had.
Really? Because I don't see much proof beyond accusations against an Italian barber that never even resulted in an indictment.
Yeah, those Italian Barbers sure are powerful and influential.
