Did William T. Thompson design the rebel flag?

William T. Thompson is often credited with designing the Confederate battle flag, also known as the "rebel flag," in 1861. He was a member of the Confederate Army and created the flag as part of a proposal for a new battle standard for the Confederate forces. The design was intended to represent the Southern states during the American Civil War. However, it's important to note that the flag has since become a symbol of controversy and differing interpretations, particularly regarding its associations with racism and rebellion.
