Hello Chris,
Great to hear you want to learn more about your father. Here in Holland there are many people like you, also trying to find out about their family history. It was back in the time the world was in great turmoil and so were family relations and records.
The founder of Maple Leaf Up, Geoff Winnington-Ball, wrote a webpage with pointers on how to research a veteran’s wartime exploits - see

Here’s hoping this is of some use to you.
Regards,
Hanno
