Alex and Carlos, thanks for your attention.
I already know the Mattioli book: those two pictures of the P-38 are well known in Italy.
I've checked the POW database at the
www.armyairforces.com looking for POW reports amongst 11 and 21 june 1943 related to operations in Sardinia but I've found anything that seems to fit to this episode.
About the 15 june 1943 MACR: according to the MACR database of the same website, 432465 was a P-38 of the 4th FG.
On that day 14th FG lost two P-38 in Sicily: one pilot was Browne, the other one was taken prisonner by italians but then he came back to his unit.
I've read it some years ago in microfilm A0741 from AFHRA.
Best regards
Gianandrea
