1989 book by Robert Ryal Miller is scholarly in tone, and includes some fascinating details, and indeed appears to have been well researched. Unfortunately, it is oddly incomplete. The book lacks the close up look at the prejudice faced by the immigrant troops, in combination with the severe discipline of the pre Civil War army. It mentions these things, but in a more detached way. The book also fails to explore the post Mexican War history of the deserters as well as The Rogues March.
