? General Lee's battle flag is not the flag of the Confederacy. The 28th Army of North Virginia used it, a unit out of Tennessee used it and it eventually became the Navy Jack. There were many battle flags.
The battle flag on the general lee is not a real confederate flag. The virginia one that most closely resembles it is square, not rectangular. They navy flag that has similar dimensions uses different colors. Yeah dukes of hazard flag and most you find in stores were never flown
What in the world are you talking about? General Lee commanded the 28th Army of Northern Virginia. It was his battle flag. The actual flag of the Confederacy has a blue field with stars and 3 bars red white and red. It changed twice and all the units had their own battle flags. https://en.wikipedia.org/wiki/Flags_of_the_Confederate_States_of_America
It is square... the flag on the car from dukes of hazard is rectangular... what don't you get? The most popular confederate flag design you can buy was never actually flown.
