I have always wondered if they chose the Cross of St. Andrew because so many Scots and Scotch-Irish settled in the South, but I’ve never researched it.
Wouldn’t surprise me if it was...............
I would’ve thought that too, but it wasn’t according to wikipedia:
“According to Coski, the “Saint Andrew’s Cross” (also used on the flag of Scotland as a white saltire on a blue field), had no special place in Southern iconography at the time, and if Miles had not been eager to conciliate the Southern Jews his flag would have used the traditional upright, “Saint George’s Cross” (as used on the flag of England, a red cross on a white field). A colonel named James B. Walton submitted a battle flag design essentially identical to Miles’ except with an upright Saint George’s cross, but Beauregard chose the diagonal cross design.”
