Morison wrote some great books on WW2, especially The Two-Ocean War (naval ops). Commager, if he’s not in your library, it ain’t a library!
I’m now reading Patriot’s History of the U.S. by Schweikert and Allen. It’s comparatively light reading but would serve today’s students adequately. (A few hundred copies per school and watch the brats start the bonfires.)
Ping.
