Their real claim to fame is "They were the only unit to not lose a single bomber on missions they have escorted".
Lots of good info here too:

My father-in-law, JC Goodwin, flew B26s in Europe in WWII, ending with 48 missions. He said the only fighter excorts the B26s could count on to stay with their mission of bomber protection and not go off hunting kills, were the Polish guys and the Tuskegee Airmen. He, even though being from Mississippi, praised the "Red Tails" as the best fighter escorts and pilots in the USAAF. He, an engineer in civilian life, believed in giving praise where praise was due.
