I have found sources stating Old Baldy was wounded between 5 to 14 times.
I found the number 5 being the most creditable as those accounts generally list the battles of Baldy being wounded & location of wounds. The sources stating 14 don't seem to list any, or a best few, battles where wounded.
I go with 5.
I think the real correct answer will turn out to be "a number of times", as it is reported variously as from three to fourteen, with "at least five" being mentioned also. I will take 14, since a few have actually counted up that many.
