Is that so? Well, it seems like he had friends in high places. This is a quote from a speech made by Ike as late as 1961:
"There was a little sergeant. His name was Culin, and he had an idea. And his idea was that we could fasten knives, great big steel knives in front of these tanks, and as they came along they would cut off these banks right at ground level—they would go through on the level keel—would carry with themselves a little bit of camouflage for a while. And this idea was brought to the captain, to the major, to the colonel, and it got high enough that somebody did something about it—and that was General Bradley—and he did it very quickly. Because this seemed like a crazy idea, they did not even go to the engineers very fast, because they were afraid of the technical advice, and then someone did have a big questions, "Where are you going to find the steel for all this thing?" Well now, happily the Germans tried to keep us from going on the beaches with great steel "chevaux de frise"—big crosses, there were all big bars of steel down on the beach where the Germans left it. And he got it—got these things sharpened up—and it worked fine. The biggest and happiest group I suppose in all the Allied Armies that night were those that knew that this thing worked. And it worked beautifully."
