the best indepth book about Luftwaffe fighter activity
 

Can anyone tell me where can I find the best books about luftwaffe fighter activity on daily reports? I overheard there is one in german within 9 or 10 volumes written by Prien, but is it even better then the books treating one jagdgeschwader apart?
I am particularily interested in pilot order or battle, and losses
Thank you much in advance. Bogdan
