It's a miracle!
In the blackpowder days, the skill of a surgeon varied. Some "apprenticed" for a few years under another "surgeon" while others actually attended a medical college. Soldiers who saw the regimental surgeon during the Civil War were prescribed all sorts of medicine including the famous blue pill. Here's a case of a miraculous recovery without assistance from the regimental surgeon.
"One of the boys in the 2nd mess, Jaber Blackmer, lost his voice and was excused for several weeks from guard duty. But one unlucky night for him, he got to dreaming and talked as plain as any man in the mess. Some of the boys heard him talking and reported him, and from that time forth he had to do his duty the same as the rest of us."
Darn if that wasn't short of a miracle!
Now, that company was commanded by Capt. Scribner and the author tells us of his misadventures too:
"Captain Scribner had a good deal of trouble with his men. Some were in the guard-house about all the time. Some were fond of whiskey, and would contrive all ways to get it. He seemed to have a particular grudge against one named Sullivan; he told him he would put him in the guard-house and keep him there almost forever. One day he was drilling them in the manual of loading and firing. He told them he would put every man in the guard-house if they didn't do just as he wanted they should. He told them to load - aim- aim higher; about one half mistook the order for aim - fire and fired. It was fun to see the Dutchman rave and storm, using language not generally heard on drill. More of the men were put into the guard-house."
Vigilantibus et non dormientibus jura subveniunt. Molon Labe!
