Beauregard was a key figure in the creation of what we today know as the Confederate flag. After the First Battle of Bull Run, Beauregard noticed that it was too easy to confuse the American flag with the Confederate “Stars and Bars” in battle because they looked similar from a distance. He worked with a few others, namely William P. Miles and Joseph E. Johnston, to create the battle flag, with a blue X with white stars (representing the states of the Confederacy) on a background of red. The flag was modified from the design of a South Carolinian secessionist flag and made into a square (rather than a rectangle) to save materials. The flag, known as the flag of the Army of Northern Virginia or “Beauregard’s flag,” was disbursed to the Army of Northern Virginia on 28 November 1861 and soon became identified with the entire Confederacy and eventually the South.
