your answer does not explain why you left it out.
your answer does not explain why they were flying it. they did not raise the flag over a captured castle to send a message to blacks.
by the time of wwii, the civil war was fading from living memory. the soldiers in question were the great grandchildren of the soldiers who fought in that war.
they were expressing regional pride, as part of a the greater whole of the usa.
the grandchildren of the union soldiers who fought along side them knew that.
i have seen no evidence that anyone was bothered by this display at that time, or at any time after that, until very recently as demonstrated by the dukes of hazzard nationwide acceptance.
By the time of WWII, the flag was a fading memory of a time past
It was not part of southern state flags, it was not flying from statehouses in the south, it was not used by the KKK
Things changed after WWII. Blacks came back from the war and demanded equal rights. That flag was brought front and center as a message to blacks what their proper place in society was
It is no longer a proper symbol
by the time of wwii, the civil war was a fading memory.
but the south was as alive and well as ever, as a strong regional part of the us
these soldiers were from that region, and were proud of their service and wanted their service and victories to honor their homes and ancestors.
it is interesting that they choose a battle flag of the confederacy instead of the national flag of the csa.
i am sure that the fighting men of the south, who did this wrote home and told their family and friends of what they were doing, and those that didn't certainly did when they got home.
and that is the beginning of the rise in popularity of the confederate battle flag in the 20th century.
not as a symbol of resistance to desegregation, but as a symbol of regional pride as part of a greater whole during the world war two.
you can see the easy acceptance that this received from the rest of the country, a generation later, when the dukes of hazzard presented the flag that way, and it was completely unremarked on.
