In his collection of essays "Of Poetry and Poets," Eberhart said that he wrote "The Fury of Aerial Bombardment" in 1944 while, as a Navy officer, teaching aerial free gunnery; that too often names of his students turned up on the death lists; and that this depressed him so much that, feeling acutely the ruthlessness and senselessness of war, he wrote the first three stanzas of the poem. It was probably a week or two later that, feeling something should be added, something quite removed from the passion of the first three stanzas, he composed the final stanza. This, he wrote, it is said, in relation to the others made the poem particularly modern and, if he had not added it, he would probably never have published the poem. "This is an example of a certain fortuitous quality determining the fate of a poem."
