I think I would go to the supermarket and read the cooking instructions on the likes of a Homepride potato bake sauce jar, and just copy that. I'm fairly sure you use raw potatoes with that and cook for about 35-45 mins at about 200 degrees C. You don't stir it or you'll disturb the layers.
You could add cheese for the last 10 mins or so. If you want to parboil them like the person above said, I'd do it for about 10 mins, drain the water off and put them back on a low heat for a minute or two to dry the potatoes off, before slicing and layering with the sauce. You'd only need to bake for about 20 mins that way.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
