Despite the heartbreak and gruesomeness that often accompanies war, there's no doubt that the subject is fascinating to read about.
Michael Inman, Curator of Rare Books at The New York Public Library, and curator of the current exhibition Over Here: WWI and the Fight for the American Mind, picked out the best nonfiction books about war.
These books are a selection of scholarly histories, journalism, first-hand accounts, and works on the tactics and theory of warfare from the crusades to the wars in Iraq and Afghanistan.
"The Crusades: The Authoritative History of the War for the Holy Land" by Thomas Asbridge

The battle for the holy land launched in 1095, and pinned Catholics and Muslims against each other for the next almost 200 years. Asbridge puts the conflict in context, from Pope Urban II's call upon "Latin Europe" to take a stand against the Muslims to the Muslim reclamation of the holy land.
Asbridge lays out a clear timeline of events, and offers a compelling retelling of the crusades that reads nothing like a history textbook.
"This Kind of War" by T. R. Fehrenbach

Taking place in part along the 38th parallel where American and North Korean troops faced off, "This Kind of War" is a profound portrayal of the Korean War which includes maps and photographs to illustrate a human perspective on war.
First published in 1963, "This Kind of War" has become a classic in military history books.
"Thank You for Your Service" by David Finkel

A MacArthur fellow and Washington Post journalist, Finkel takes an in-depth look at some of the psychological issues, including PTSD, that plagued many of his fellow battalion members after returning from service in the Iraq war.
A sequel, if you will, to his book "The Good Soldiers,""Thank You for Your Service," presents snapshots of Finkel's battalion mates post-war, and how their service has affected their lives and loved ones.
