Danny,
It looks like we'll have to find an original family source to find out for sure whether the name was Gibson or Gipson.
Bryan was saying that another source claimed the battalion had nine companies (Sifakis). He said that he had not been able to verify that claim. Considering the battalion only existed from approximately mid-July until mid-September, the sources you provided dated July 27th and August 28th would seem to confirm the battalion only had five companies.
I really appreciate all the unique sources you shared in this thread. They definitely shed a lot of light on the brief existence of Chew's Battalion.
