I don't think I know enough about any of the campaigns in World War Two. I really don't know anything yet, I've just begun researching for about a year now and there's just so much to learn. Everyday it's just overwhelming how much there is out there, I want to learn it all but don't think that's ever going to happen, but hey, I'll do my best.
I really would like to know about the Russian campaign more. Every WWII historian mentions it so highly, I would really like to research it more.
