What I published is from the OR's. I can tell you the 2nd SC reports are in the OR's from Chicamauga. I can check on the rest put doubt they are in there.
Sadly one of the best authors/letter writer from Kershaw's Brigade, Dick Talley from the 3rd was killed at Chicamauga. If you'd are looking for information on Kershaw's Brigade, try Mac Wykoff at the Frederickburg NPS. There's probably few people as knowledgable about the brigade as he.
