Every book I read about the P-38 mentions its first victory in the ETO as shooting down an Fw 200C near Iceland. The most specific sources list the pilot as Elza Shaham, and that he shared the victory with a P-40C, on August 14, 1942.
However, several other sources report a P-38 "shooting down an Fw 200 within hours of the declaration of war", ie Dec. 8, 1941. One such source is
American Warplanes of WWII edited by David Donald. Another is Bill Gunston's
Combat Aircraft of World War II. Neither of these sources get more specific than that. It would seem, based on the more detailed evidence of other sources, from Einzo Angelucci's
The American Fighter to multiple other sources including Wikipedia, that the Elza Shaham August 1942 report is accurate. For instance, what on earth would US Army P-38's have been doing in Iceland before the declaration of war? They were just marginally operational stateside, let alone on foreign soil. David Donald's book lists it as a P-38E, whereas others refer to it as a P-38F.
So. What I want to know is, if this oft-repeated rumor is false, how did it get started? Who is responsible, and what is the legacy of this myth? To me this is almost as reprehensible as the myth (perpetuated, at least, by John Wayne) that the Flying Tigers were in routine combat with the Japanese before the US declaration of war.
The other question is, what else can we learn about the P-38's, P-40's, and from one source I seem to remember, P-39's? that operated out of Iceland during the war? Many discussions of the P-40 mention how it was never used in the ETO (although it was indeed used in Italy, in the MTO) by the USAAF. I suppose you could say that Iceland wasn't really part of the ETO, but rather the ATO, or Atlantic Front. But what about these units, and their operational history? What more can we learn about them?
