OK, I can't help you with the surgeon. Was going to give you Lt. J. B. Pirtle, one NCO, and nineteen men from the 1st Texas Sharpshooters Bn., but it seems that's not what you need. (The official reports give the 1st Tex SS Bn's contribution as 25 men, but according to the battalion's records, there were 60 involved on Queen of the West, Webb, and Grand Era.)
