My dad, Gordon Brant, was in the 484th BG, 824th SQ based in Torretta. I recently found a document authored by my dad that stated that he was based in Africa for awhile, presumedly prior to going to Torretta. I would be interested to find any information about the 824th Sqd in Africa (dates, base name, etc) during WWII.
I know that many of the 484th bomb groups flew from Nova Scotia, to the Azores and then to Marrakesh, North Africa. My uncle Woody Wilson in the 827th squadron made that trip. He and his flight engineer James Clemmons got the DFC for saving their plane when the engine caught fire leaving Marrakesh. This was sometime between May and August of 1944. They got to Torretta near the end of August. Their first mission was hauling oil and gas to Southern France to Patton's 3rd army.
Take a look at Torretta Flyer number 14, page 16. There is a humerous story about the route over to Italy. I don't think anyone spent much time in Africa going to the war zone but after the 484th left Italy I think they went to Casablanca for a couple of months.
