The only reference we could find [ed.] is the story told by Harry McEvoy in one of his books. It is the story of Skeeter Vaughan.

McEvoy wrote that during World War II, Skeeter Vaughan was deployed somewhere on the German lines. It happened that one particular mission assigned to the squad that Skeeter was part of was to neutralize a German sentry post. From Skeeter's position, a sentry was downhill across an open area at a range of over 100 feet. A building, presumably filled with other enemy, was very nearby. Making noise was out of the question, so firing weapons was not desired. I was decided that Skeeter should attempt a knife throw. He then moved as close as possible without giving up his presence. His position is estimated at about 90 feet. From here Skeeter made the throw, in a night lit, downhill and long range situation. There was silence. Assuming a miss, the squad prepared for the worse and moved in towards the sentry's position ready for a fight. Once at the sentry's position, they found the knife had hit its target in the upper body area and silently eliminated the sentry.

Skeeter retrieved the knife and the sentry post was neutralized. For the details, see Harry McEvoy's story in: Knife & Tomahawk Throwing: The Art Of The Experts, pp. 92-94.
