The more commonly seen Confederate Battle Flag is the “Southern Cross”, not the “Stars and Bars”. The latter refers to the CSA national flag.
The stars ‘n’ bars is the term loosely associated with the Confederate battle flag, for better or worse. Most of the clowns who stigmatize the south are not historians.
From Wikipedia:
The first official flag of the Confederacy, called the “Stars and Bars,” was flown from March 5, 1861, to May 26, 1863.
The very first national flag of the Confederacy was designed by Prussian artist Nicola Marschall in Marion, Alabama.[1] The Stars and Bars flag was adopted March 4, 1861 in Montgomery, Alabama and raised over the dome of that first Confederate Capitol. Marschall also designed the Confederate uniform.[2]
One of the first acts of the Provisional Confederate Congress was to create the Committee on the Flag and Seal, chaired by William Porcher Miles of South Carolina. The committee asked the public to submit thoughts and ideas on the topic and was, as historian John M. Coski puts it, “overwhelmed by requests not to abandon the ‘old flag’ of the United States.” Miles had already designed a flag that would later become the Confederate battle flag, and he favored his flag over the “Stars and Bars” proposal. But given the popular support for a flag similar to the U.S. flag (”the Stars and Stripes”), the Stars and Bars design was approved by the committee.[3] When war broke out, the Stars and Bars caused confusion on the battlefield because of its similarity to the U.S. flag of the U.S. Army.[4]
