I think the stars are too large to be a first wool bunting. I have always suspected that the flag in the photo is the 11th Alabama Infantry in our collection. A reporter who interviewed McClellan shortly after, described the flag mentioning the tear through the cross and an attached cotton square detailing the capture information. Note the image and provenance of the 11th in my flag report. No facts beyond that, just a suspicion. Hope all is well.
