Paul Fussell’s best-known book is The Great War and Modern Memory. In that book, he wrote about the effect of World War I, especially trench warfare, on British writers. Wartime is Fussell’s similar book about World War II. This one isn’t mainly concerned with the war’s effect on writers, however. It has a much broader scope. There are discussions, for example, of the myth of “precision” bombing; the frequency of military foul-ups; rumors; rationing; stereotypes; accentuating the positive; casualty rates; popular songs; swearing; hunger; and sexual frustration. There is even a whole chapter devoted to “chickenshit” – the petty crap that superiors inflict on subordinates.
Fussell wrote from experience. He was awarded the Bronze Star and the Purple Heart as an infantry officer in France. His goal in Wartime was to capture the reality of World War II as it was endured by American and British soldiers, sailors and airmen, especially those who actually saw combat (a small minority of those who served). He often does this by contrasting military reality with the sanitized version presented to the people back home. If you were in the service but not in combat, your main emotions were boredom and anger. If you were in combat, it was fear and horror.
According to Fussell, the authorities eventually realized that engaging in more than 240 days of combat (not consecutive days, but total days) would drive anyone insane. That sums up World War II for the men who did the actual fighting.
