I found a Newsweek link. It says a commando, one of ours, hit him or hit him with a rifle butt. Check it out.

Had one heckuva time getting your link to completely open yet I did get to read far enough down to see that part. You're right and I stand corrected. Thank you for finding it. That must have been one soul-satisfying blow!
