At least give Prof. Foner credit for presenting the military part of the war seriously. When I took David Donald's CW course back in the late 80s, he barely mentioned the "war" part of the CW. Some of us undergrads at the time met him after class asked him about that. I forget his exact words, but Prof. Donald gave the impression that he did not feel comfortable lecturing about war on the Harvard campus back then. Instead, he suggested that we read the Killer Angels.
