Flad index at ADAH does not include this regiment. All the other regiments in Wilcox's Brigade are represented, so you can check them to see examples of other flags that would have been identical. Over time flags became worn and torn, and others were captured. Few if any regiments carried the same flag throughout the war. The 9th Alabama Regiment likely carried several between 1861 and 1865.
