Who is Wally Moon from Goodbye, Darkness: A Memoir of the Pacific War and what is their importance? "Goodbye

Wally Moon is one of the original enlisted men in the author's intelligence section. He is described as a little corpulent, eccentric and peculiar, devoid of social graces, but very intelligent. Before his military service, Moon attended MIT with the class of 1943, intending to become a physicist. Moon adopts the peculiar habit of always sleeping alone in his own foxhole—nearly all Marines paired off for security reasons. Moon dies during one rainy night when an artillery barrage collapses his foxhole and he is trapped under the mud and drowns. The author comments particularly upon the waste of life and future possibility when Moon's death is described.
