Those facing the 15th in Italy rarely had the newest and best equipment, or were minor axis airforces (Like Romania or Croatia, for example.)These air forces, while rather enthusiastic in fighting the Red Army, saw the western allies differently, and it was rather daunting for even the Luftwaffe to approach the "combat boxes" of the B-17s/24s from the 12 O'Clock high position (head on, in a slight dive, so as to shoot up the cockpit and nose). Closing speeds were well, high, and it took nerves of steel to attempt this, and the other German allied AFs did simply didn't have the equipment or training to attempt this.
Also, everything that I have read about to the Tuskegee says they had no respect for the Germans and their allies. But, I think if they had faced the likes of JG 26 or 54, they might have had a rude shock. Just ask guys from 4th or 56th Fighter Group. They lost bombers..but they gave better than they got. I think if the Tuskegee had been on the Channel front, they would have had to learn fast, or die.
But with dad, it was personal with that particular unit. He also didn't like Mark Clark much . . . because he drowned some of his buddies in the Rapido river . . .
My dad can hold a grudge like nobody I've ever seen. When he got back from the war, Muse's, a local men's store, refused to sell him a suit because wool was still rationed and they were "saving their suits for their regular customers." "Then I," said dad, "will NEVER be a regular customer!" He kept his word, he never darkened their door - my sister bought him a tie from Muse's, he didn't return it, he had MOM return it. Muse's went out of business some time in the late 80s, and dad rejoiced, he outlasted 'em.
