The "Stars and Bars" was also known as the 1st National Flag. It consisted of three horizontal bars, two red and one white, and a blue canton with a circular constellation of 13 stars, one each for the 11 states of the Confederacy, plus Missouri and Kentucky, which were prevented from seceding by Federal action. This flag closely resembled the US flag at the time, especially when not flying straight out with the wind. As this sometimes caused confusion on the battlefield, P.G.T. Beauregard designed the battle flag, which has come to be recognized by all. In fact, the original battle flag was square, and the current rectangular version was the naval ensign.

Later versions of the national flag incorporated the battle flag design in the canton, with either a white field (2nd National) or a white field edged with red on the fly (3rd National).

I don't remember the exact dates that these flags were used, but I have the information at home where I can look it up if anyone is interested.
