**Readers of the first edition of this book will note significant differences in the accounting and chronology of the losses suffered by the Group on this mission, for which some explanation is in order. The account in the original version of this chapter was based on a chronology derived from crew observations in the Group’s mission file, together with certain inferences drawn by the writer regarding which PFF aircraft was lost, and when, from Roger Freeman’s original 8^th Air Force history, The Mighty Eighth. The new chronology is based not only on the Group’s mission file, but also on the additional personal accounts of Jack Fawcett and Vern Moncur contained in this chapter, the extensive MACR (Missing Air Crew Report) data summarized by Harry D. Gobrecht in his 303^rd history, Might in Flight, and much more specific aircraft loss information contained in Roger Freeman’s latest B-17 book, The B-17 Flying Fortress Story: Design, Production, History, which establishes that Capt. Lecates’ PFF ship, B-17F 42-3491, was not lost in action until March 3, 1944. Even with this new information, however, it is impossible to reconcile all contradictions in points of view and time in a battle this intense and chaotic. It goes without saying that the chronology presented here represents the writer’s best analysis of what happened when, and that I bear full responsibility for any errors that remain.
