My sources for the present piece have been: daily operations/intelligence summaries of Mediterranean Allied Strategic Air Force (MASAF) and Mediterranean Allied Tactical Air Force (MATAF); 8th US Air Force Mission Reports; RAF Operations Record Books; Mediterranean Allied Air Forces (MAAF) Signals Intelligence Reports; prisoner of war reports; Government Code & Cipher School reports on deciphered Luftwaffe communications; a list of JGr. 200 casualties (thanks to J. Richard Smith); Tony Wood’s compilation of accredited Luftwaffe victories; USAAF Missing Air Crew Reports at fold3.com plus the database at armyairforces.com; and the USAAF Honour Rolls on the Shark Squadron site.
Mission reports and other useful material are reproduced on several excellent websites commemorating the USAAF Bombardment, Fighter and Fighter Bomber Groups operating over Southern France in 1944, for example:
The huge collection of US 8th AF fighter pilots' Encounter Reports at http://www.wwiiaircraftperformance.org/ was helpful regarding the action of 14 July 1944.
For the Free French Air Forces, I consulted:
… and some barely legible operations reports on microfilm at the National Archives.
Information about Uffz. Cöster's temporary captivity came from:
My thanks to Jan Bobek, Guy Julien and Lino von Gartzen for the information and comments they contributed in response to the publication of the first section of this article. The discussions on the Luftwaffe section of the French site Südwall Superforum have also brought some useful comments. Klaus Fischer and Lino von Gartzen have compiled a list of over 500 pilots who flew with Jagdgruppe Süd and Jagdgruppe 200. Steve Coates provided me with a copy of document Ob.d.L. Fü.St. Ia 8947/43 (which is held in the US National Archives).
I’ve tried as far as possible not to use published sources here, except to cross-check a few points after I’d drafted a narrative from the archival material. This is supposed to be my version of the story and it differs in several particulars from what I've seen in print. Of course you can’t completely do without other people’s work and I’ve referred to:

A recent French publication which covers the air combat leading up to and during operation Dragoon is:
Guy Julien & Christian-Jacques Ehrengardt Combats dans le Ciel de Provence, Aéro Journal Hors-série No. 2 (2009)
I didn't read my copy until after completing this article. It includes one-page biographies of Eduard Isken and Horst Rippert of JGr. 200 as well as many firsthand accounts from the American side. Guy's narrative of the 1st FG's action against JGr. 200 on 15 August 1944 is especially good.
