I'd suggest Stan Bishops books.
Losses of the 8th and 9th Air Forces.

Volume 4 is currently in progress and will cover up until Sept 1944.
Stan informs me that co author John Hey has sadly passed away so its Stan thats carrying the baton now.
Good luck tracing copies, especially Volume 1.
However, if you have specific questions relating to a certain date then I'm sure someone who owns a copy will be able to give you the information listed in the book.
All the best,
Nige
