should (I guess you have) document it all and continue the research when those items become declassified. I'm so sorry your dad had so many health issues from his service.
As far as my knowledge goes, there is some basic stuff I'd tell you only in a message so as not to ID myself to anyone on this board. But other things, I learned from watching those abbreviated documentary series on cable tv, such as WWII in Color. They have segments on various turning points in military actions, including the capture and liberation of Malta, how Montgomery took the place of another British general in N. Africa, the taking of El-Alamein, etc.
What was striking to me as an adult was Hitler's hubris in firing so many of his generals. ("I know more than the generals. 
) He lost the war not just by taking on Russia, but not having clear reasons for attempting to take certain areas.
The movie with Benedict Cumberbatch about Enigma was pretty good. I don't know how much of the technical stuff was reality. But one dramatic (and likely untrue) detail in the movie that was so heartbreaking was when they discovered they had the code, and realized the next attack from that first decripted message would be against an Allied resupply convoy. One of the people in the group had a brother aboard one of the ships. The sibling insisted they be warned. The mathematician said they couldn't; that would have to be a strategic decision by the generals and pols. Preventing every attack using sigint would tip off the Germans. They needed to keep the secret until more critical objectives could be achieved. I had never thought about that detail and the pain and guilt it creates in sacrificing "pawns."
I'll send you a message shortly.
