Who warned general braddock about the danger of ambushes on the way to battle?

The correct answer is Benjamin Franklin. He mentions in his Autobiography that he knew that an ambush was being prepared and that he warned general Braddock but the general disregarded this and the rest of what happened is history. The terrible outcome was not prevented even though he warned him.
