Careful when you throw numbers around. 3000-5000 soldiers dead was the ENTIRE count for D-Day during the operation. I seriously doubt that this single soldier was responsible for every death on that day. (Not ot say he didn't kill a LOT of people).
Can you provide any further links?
You're right, I've just realized it comparing the numbers. Unfortunately - the only link I can provide is in Polish, so - I don't think it would be useful for You.
