Victims of wolf pack attacks might have done better if they were able to avoid being attacked simultaneously, or from behind.
Historically, those who succeeded in finding a tree survived more often and with less injuries.
You might doubt your ability to kill a bunch of wolves but I know mine and I would not have any trouble.
Treadwell was not armed and didn't want to kill a thing, I an accomplished hunter with thousands of kills behind me. I would have no trouble pulling the trigger time and time again on a pack most likely it would be rather fun.
