Personally, I don't believe it. Stretching the topic a bit, I'd like to relate a story I was told when I worked as a masonry laborer during college summers.

One of the masons told me he was in a bridge building outfit during WWII, and one day while they were building a bridge (and taking sporadic enemy fire) across some unknown river in France, a jeep with general's stars came barrelling up to the bank of the river. Patton hopped out (wearing the ivory gripped sidearms), and said "Hurry up and get that bridge done boys, I want to go over there and shoot my guns." Then he jumped back in the jeep and away it went.

The man who told me this story said he and the troops LOVED Patton. I got the impression they admired him for exposing himself to fire near the front, just like they were doing. Sorry for going off topic here, but snippets like this show the myth surrounding Patton had a basis in fact.
