No, as far as I know, Torretta Field was never bombed. There is nothing in the records to indicate that Torretta Field was ever attacked. I suppose that with as many Allied field that were in the area, the Axis couldn't get close and by early 1944 when Torretta Field was established, that area of Italy was fairly secure.
I do remember hearing of a German fighter that buzzed the field once, but it didn't attack. That was the closest Torretta Field ever came to being attacked.
My Dad wrote about that buzzing incident in his memoirs. He did a real nice job of compiling a 256 page memoir of diary entries, orders, mission recaps and personal thoughts. Let me know if anyone is nterested in a peek. Teflonlawyer@yahoo.com
