This flag was used to replace the stars and bars because they could not tell the difference form the unions flag,and thier flag in battle.I think it is interesting because it is perfectly square and has white bands on all three sides.This preticular flag is unique to the army of the Northern Virginia.It is different than the Confederate flag carried by Tennessee forces.Even though the flag had 13 stars only 11 states seceded from the Union.So the two stars that were included were border states that favoured the confederacy but didnt officialy secceed (Missouri,and Kentucky).
