Top Five Books on War

I read lots of books on war, inspired by a freshman writing seminar that I took with James Tatum at Dartmouth many years ago. (He turned that seminar into a book.) Here are, in my estimation, the top five books on war:

1. The Illiad by Homer

2. The Things They Carried by Tim O’Brien

3. The Red Badge of Courage by Stephen Crane

4. Matterhorn: A Novel of the Vietnam War by Karl Marlantes

5. A Rumor of War by Philip Caputo

I acknowledge the emphasis on Vietnam, but it seems that war generated some of the greatest writing of any war.

What books do you think I’m missing?
