Wave Your Grand Army of the Republic Banner High?

History can help a bit with the issue around the Confederate flag (truly the Battle Flag), though it can’t solve everything.  In this cast part repeat and current commentary we reexamine some questions.  Were confederates traitors, thus the flag a flag of illegality?  What flag would have flown over Charleston when the Civil War began?  When did that term Civil War start being used?, and what did they call the war before?  And what about that time when the North would have been the one waving flags around?
