Under the Bombs tells the story of the civilian population of German cities devastated by Allied bombing in World War II. These people went to work, tried to keep a home (though in many cases it was just a pile of rubble where a house once stood), and attempted to live life as normally as possible amid the chaos of war. Earl Beck also looks at the food and fuel rationing the German people endured and the problems of trying to make a public complaint while living in a totalitarian state.

In a book arranged in chapters which deal separately with the Home Fronts of each country, Beck is able to provide a comprehensive picture of the effects of the world's only 'total war' upon the civilians who often faced bewilderment, fear, death, and destruction all around them. Beck considers the effects of bombing and sometimes actual fighting in the streets and towns in which people lived, and the policies of individual governments that attempted to encourage and retain support for the war effort in varying ways.
