The year is 1942, and while America is reeling from the first blows of WWII, Osgood is just a nine-year-old boy living in Baltimore. As the war rages somewhere far beyond the boundaries of his hometown, he spends his days delivering newspapers, riding the trolley to the local amusement park, going to Orioles' baseball games, and goofing around with his younger sister.

With a sharp eye for details, Osgood captures the texture of life in a very different era, a time before the polio vaccine and the atomic bomb. In his neighborhood of Liberty Heights, gaslights still glowed on every corner, milkmen delivered bottles of milk, and a loaf of bread cost nine cents.

Osgood reminisces about his first fist-fight with a kid from the neighborhood, his childhood crush on a girl named Sue, and his relationship with his father, a traveling salesman. He also talks about his early love for radio and how he used to huddle under the covers after his parents had turned off the lights, listening to Superman, The Lone Ranger, The Shadow, and, of course, to baseball games.

Defending Baltimore Against Enemy Attack is a gloriously funny and nostalgic slice of American life and a moving look at World War II from the perspective of a child far away from the fighting, but very conscious of the reverberations.
