GDG- 1st day

[MICHAEL DAVIDSON]

Hi.  I'm a new subscriber, getting my feet wet.  I've been reading some of the discussions with fascination, and though I never subscribe to lists or discussion groups, I could not resist this one, Gettysburg being one of my favorite spots on the globe.
   
  I have a research question.  In Shue's "Morning at Willoughby Run," p 127, there are two paragraphs that especially caught my eye, about a private R.E. Davidson of the 2nd Wisconsin,  Co. H, who, after Reynolds, his colonel, his lt. colonel, and his color bearer went down, grabbed the colors and led his unit in a charge down Herbst's Woods.
   
  I'm not on an ancestor hunt, but the name has enlivened my informal tours for family and friends.  But I haven't been able to confirm the story.  Shue attributes it to Stine, "History of the Army of the Potomac," pp 730-731.  I haven't found Stine on line.  I haven't found the story in any of many other books I have on the battle.
   
  The Wisconsin roster of volunteers (http://www.wisonsinhistory.org/roster/) lists a Russalas Davison ("Rasselas" in the company roster), in the 2nd Wis., Co. H, who served from Apr. 24 '61 to June 29 '64.  The missing second "d" is not problem, it's an acceptable spelling of the family name, and the folks who maintain the roster note that there are spelling discrepancies because of the difficulty of transcribing old, handwritten ledgers.  However, Shue says Davidson "fought at Antietam, Chancellorsville, and in both battles at Bull Run, and had come through all of them unscathed."  The Wisconsin registry says "wnd. Antietam."  Shue says he was a private, promoted to Sergeant for his actions on July 1.  The Wisconsin registry has his ranks as "Corp., Sergt."   I don't know if the descrepancies are Shue's, or Stine's, or whether for certain I have found "a most unlikely private...R. E. Davidson."
   
  I would be glad for any leads and suggestions.
