The full list is (for now) complied on the site Letterboxd under the same title, WWII Films In Chronological Order - TgL, link. For now this is a work in progress, with the list updated regularly as more films are watched. And this is, nor will ever be, a full list of movies on the subject--but the list is growing.
I've also started to compile a brief list of useful links on the subject. With the project well under way, yet still far from complete, this list will likely be ammended again later (see comments below):
