I also learned much about World War II from the veterans with whom I traveled to battlefields in Italy, the Solomon Islands, and Normandy. For their service to their country, and for their generosity to me, I thank them.
Several research assistants have given me invaluable help: Leslie Berlin, Elizabeth Kopelman Borgwardt, Mark Brilliant, Kyle Graham, Tom Jackson, Sean Malloy, John McGreevy, and Jonathan Schoenwald.
